Decred aims to build a community-directed cryptocurrency whose security, adaptability, and sustainability make it a superior long-term store of value. It is achieving this aim by building the world's first truly decentralized autonomous organization.
Dragonchain Great Reddit Scaling Bake-Off Public Proposal
Dragonchain Public Proposal TL;DR:
Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and postsper Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625. Watch Joe walk through the entire proposal and answer questions onYouTube. This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!
I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale. For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube. We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoC
In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks. 24 hours in 4 minutes (YouTube): 24 hours in 4 minutes The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period. Tooling to reproduce our demo is available here: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired. Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity. TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block. TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain. With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times. We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment. Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in Scaling
Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems. We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node. Getting started is easy...
Download Dragonchain’s dctl
Input three commands into a terminal

Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain. Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain. After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks. Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD. For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments. Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users. Over a 5 day period, your scaling PoC should be able to handle: *100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes. Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum. Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node. Examples:
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users. All of Reddit's Transactions on Blockchain (month) Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees. Reddit Internal Token Transaction Fees Reddit Ethereum Token Transaction Fees When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here. Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here. In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here. A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible APIs should be well documented and stable
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected. Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR. Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus points Public, third-party implementation review available or in progress
Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).
Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open Source
The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group. https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html
In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney. Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects
Verify no conflict of interest
Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
Obtain legal approval
Approval from corporate, parks, and other business units
Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
Trademark searches conducted for the selected name Dragonchain
Obtain IT security approval
Manual review of OSS components conducted
OWASP Dependency and Vulnerability Check Conducted
Obtain technical (software) approval
Offer management, process, and financial plans for the maintenance of the project.
Meet list of items to be addressed before release
Remove all Disney project references and scripts
Create a public distribution list for email communications
Remove Roets’ direct and internal contact information
Create public Slack channel and move from Disney slack channels
Create proper labels for issue tracking
Rename internal private Github repository
Add informative description to Github page
Expand README.md with more specific information
Add information beyond current “Blockchains are Magic”
Add getting started sections and info on cloning/forking the project
Add installation details
Add uninstall process
Add unit, functional, and integration test information
Detail how to contribute and get involved
Describe the git workflow that the project will use
Move to public, non-Disney git repository (Github or Bitbucket)
Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney. The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

A common sentiment is brewing online; a shared desire for the internet that might have been. After decades of corporate encroachment, you don't need to be a power user to realize that something has gone very wrong. In the early days of the internet, the future was bright. In that future, when you sent an instant message, it traveled directly to the recipient. When you needed to pay a friend, you announced a transfer of value to their public key. When an app was missing a feature you wanted, you opened up the source code and implemented it. When you took a picture on your phone, it was immediately encrypted and backed up to storage that you controlled. In that future, people would laugh at the idea of having to authenticate themselves to some corporation before doing these things. What did we get instead? Rather than a network of human-sized communities, we have a handful of enormous commons, each controlled by a faceless corporate entity. Hey user, want to send a message? You can, but we'll store a copy of it indefinitely, unencrypted, for our preference-learning algorithms to pore over; how else could we slap targeted ads on every piece of content you see? Want to pay a friend? You can—in our Monopoly money. Want a new feature? Submit a request to our Support Center and we'll totally maybe think about it. Want to backup a photo? You can—inside our walled garden, which only we (and the NSA, of course) can access. Just be careful what you share, because merely locking you out of your account and deleting all your data is far from the worst thing we could do. You rationalize this: "MEGACORP would never do such a thing; it would be bad for business." But we all know, at some level, that this state of affairs, this inversion of power, is not merely "unfortunate" or "suboptimal" – No. It is degrading. Even if MEGACORP were purely benevolent, it is degrading that we must ask its permission to talk to our friends; that we must rely on it to safeguard our treasured memories; that our digital lives are completely beholden to those who seek only to extract value from us. At the root of this issue is the centralization of data. MEGACORP can surveil you—because your emails and video chats flow through their servers. And MEGACORP can control you—because they hold your data hostage. But centralization is a solution to a technical problem: How can we make the user's data accessible from anywhere in the world, on any device? For a long time, no alternative solution to this problem was forthcoming. Today, thanks to a confluence of established techniques and recent innovations, we have solved the accessibility problem without resorting to centralization. Hashing, encryption, and erasure encoding got us most of the way, but one barrier remained: incentives. How do you incentivize an anonymous stranger to store your data? Earlier protocols like BitTorrent worked around this limitation by relying on altruism, tit-for-tat requirements, or "points" – in other words, nothing you could pay your electric bill with. Finally, in 2009, a solution appeared: Bitcoin. Not long after, Sia was born. Cryptography has unleashed the latent power of the internet by enabling interactions between mutually-distrustful parties. Sia harnesses this power to turn the cloud storage market into a proper marketplace, where buyers and sellers can transact directly, with no intermediaries, anywhere in the world. No more silos or walled gardens: your data is encrypted, so it can't be spied on, and it's stored on many servers, so no single entity can hold it hostage. Thanks to projects like Sia, the internet is being re-decentralized. Sia began its life as a startup, which means it has always been subjected to two competing forces: the ideals of its founders, and the profit motive inherent to all businesses. Its founders have taken great pains to never compromise on the former, but this often threatened the company's financial viability. With the establishment of the Sia Foundation, this tension is resolved. The Foundation, freed of the obligation to generate profit, is a pure embodiment of the ideals from which Sia originally sprung. The goals and responsibilities of the Foundation are numerous: to maintain core Sia protocols and consensus code; to support developers building on top of Sia and its protocols; to promote Sia and facilitate partnerships in other spheres and communities; to ensure that users can easily acquire and safely store siacoins; to develop network scalability solutions; to implement hardforks and lead the community through them; and much more. In a broader sense, its mission is to commoditize data storage, making it cheap, ubiquitous, and accessible to all, without compromising privacy or performance. Sia is a perfect example of how we can achieve better living through cryptography. We now begin a new chapter in Sia's history. May our stewardship lead it into a bright future.
Today, we are proposing the creation of the Sia Foundation: a new non-profit entity that builds and supports distributed cloud storage infrastructure, with a specific focus on the Sia storage platform. What follows is an informal overview of the Sia Foundation, covering two major topics: how the Foundation will be funded, and what its funds will be used for.
The Sia Foundation will be structured as a non-profit entity incorporated in the United States, likely a 501(c)(3) organization or similar. The actions of the Foundation will be constrained by its charter, which formalizes the specific obligations and overall mission outlined in this document. The charter will be updated on an annual basis to reflect the current goals of the Sia community. The organization will be operated by a board of directors, initially comprising Luke Champine as President and Eddie Wang as Chairman. Luke Champine will be leaving his position at Nebulous to work at the Foundation full-time, and will seek to divest his shares of Nebulous stock along with other potential conflicts of interest. Neither Luke nor Eddie personally own any siafunds or significant quantities of siacoin.
The primary source of funding for the Foundation will come from a new block subsidy. Following a hardfork, 30 KS per block will be allocated to the "Foundation Fund," continuing in perpetuity. The existing 30 KS per block miner reward is not affected. Additionally, one year's worth of block subsidies (approximately 1.57 GS) will be allocated to the Fund immediately upon activation of the hardfork. As detailed below, the Foundation will provably burn any coins that it cannot meaningfully spend. As such, the 30 KS subsidy should be viewed as a maximum. This allows the Foundation to grow alongside Sia without requiring additional hardforks. The Foundation will not be funded to any degree by the possession or sale of siafunds. Siafunds were originally introduced as a means of incentivizing growth, and we still believe in their effectiveness: a siafund holder wants to increase the amount of storage on Sia as much as possible. While the Foundation obviously wants Sia to succeed, its driving force should be its charter. Deriving significant revenue from siafunds would jeopardize the Foundation's impartiality and focus. Ultimately, we want the Foundation to act in the best interests of Sia, not in growing its own budget.
The Foundation inherits a great number of responsibilities from Nebulous. Each quarter, the Foundation will publish the progress it has made over the past quarter, and list the responsibilities it intends to prioritize over the coming quarter. This will be accompanied by a financial report, detailing each area of expenditure over the past quarter, and forecasting expenditures for the coming quarter. Below, we summarize some of the myriad responsibilities towards which the Foundation is expected to allocate its resources.
Maintain and enhance core Sia software
Arguably, this is the most important responsibility of the Foundation. At the heart of Sia is its consensus algorithm: regardless of other differences, all Sia software must agree upon the content and rules of the blockchain. It is therefore crucial that the algorithm be stewarded by an entity that is accountable to the community, transparent in its decision-making, and has no profit motive or other conflicts of interest. Accordingly, Sia’s consensus functionality will no longer be directly maintained by Nebulous. Instead, the Foundation will release and maintain an implementation of a "minimal Sia full node," comprising the Sia consensus algorithm and P2P networking code. The source code will be available in a public repository, and signed binaries will be published for each release. Other parties may use this code to provide alternative full node software. For example, Nebulous may extend the minimal full node with wallet, renter, and host functionality. The source code of any such implementation may be submitted to the Foundation for review. If the code passes review, the Foundation will provide "endorsement signatures" for the commit hash used and for binaries compiled internally by the Foundation. Specifically, these signatures assert that the Foundation believes the software contains no consensus-breaking changes or other modifications to imported Foundation code. Endorsement signatures and Foundation-compiled binaries may be displayed and distributed by the receiving party, along with an appropriate disclaimer. A minimal full node is not terribly useful on its own; the wallet, renter, host, and other extensions are what make Sia a proper developer platform. Currently, the only implementations of these extensions are maintained by Nebulous. The Foundation will contract Nebulous to ensure that these extensions continue to receive updates and enhancements. Later on, the Foundation intends to develop its own implementations of these extensions and others. As with the minimal node software, these extensions will be open source and available in public repositories for use by any Sia node software. With the consensus code now managed by the Foundation, the task of implementing and orchestrating hardforks becomes its responsibility as well. When the Foundation determines that a hardfork is necessary (whether through internal discussion or via community petition), a formal proposal will be drafted and submitted for public review, during which arguments for and against the proposal may be submitted to a public repository. During this time, the hardfork code will be implemented, either by Foundation employees or by external contributors working closely with the Foundation. Once the implementation is finished, final arguments will be heard. The Foundation board will then vote whether to accept or reject the proposal, and announce their decision along with appropriate justification. Assuming the proposal was accepted, the Foundation will announce the block height at which the hardfork will activate, and will subsequently release source code and signed binaries that incorporate the hardfork code. Regardless of the Foundation's decision, it is the community that ultimately determines whether a fork is accepted or rejected – nothing can change that. Foundation node software will never automatically update, so all forks must be explicitly adopted by users. Furthermore, the Foundation will provide replay and wipeout protection for its hard forks, protecting other chains from unintended or malicious reorgs. Similarly, the Foundation will ensure that any file contracts formed prior to a fork activation will continue to be honored on both chains until they expire. Finally, the Foundation also intends to pursue scalability solutions for the Sia blockchain. In particular, work has already begun on an implementation of Utreexo, which will greatly reduce the space requirements of fully-validating nodes (allowing a full node to be run on a smartphone) while increasing throughput and decreasing initial sync time. A hardfork implementing Utreexo will be submitted to the community as per the process detailed above. As this is the most important responsibility of the Foundation, it will receive a significant portion of the Foundation’s budget, primarily in the form of developer salaries and contracting agreements.
Support community services
We intend to allocate 25% of the Foundation Fund towards the community. This allocation will be held and disbursed in the form of siacoins, and will pay for grants, bounties, hackathons, and other community-driven endeavours. Any community-run service, such as a Skynet portal, explorer or web wallet, may apply to have its costs covered by the Foundation. Upon approval, the Foundation will reimburse expenses incurred by the service, subject to the exact terms agreed to. The intent of these grants is not to provide a source of income, but rather to make such services "break even" for their operators, so that members of the community can enrich the Sia ecosystem without worrying about the impact on their own finances.
Ensure easy acquisition and storage of siacoins
Most users will acquire their siacoins via an exchange. The Foundation will provide support to Sia-compatible exchanges, and pursue relevant integrations at its discretion, such as Coinbase's new Rosetta standard. The Foundation may also release DEX software that enables trading cryptocurrencies without the need for a third party. (The Foundation itself will never operate as a money transmitter.) Increasingly, users are storing their cryptocurrency on hardware wallets. The Foundation will maintain the existing Ledger Nano S integration, and pursue further integrations at its discretion. Of course, all hardware wallets must be paired with software running on a computer or smartphone, so the Foundation will also develop and/or maintain client-side wallet software, including both full-node wallets and "lite" wallets. Community-operated wallet services, i.e. web wallets, may be funded via grants. Like core software maintenance, this responsibility will be funded in the form of developer salaries and contracting agreements.
Protect the ecosystem
When it comes to cryptocurrency security, patching software vulnerabilities is table stakes; there are significant legal and social threats that we must be mindful of as well. As such, the Foundation will earmark a portion of its fund to defend the community from legal action. The Foundation will also safeguard the network from 51% attacks and other threats to network security by implementing softforks and/or hardforks where necessary. The Foundation also intends to assist in the development of a new FOSS software license, and to solicit legal memos on various Sia-related matters, such as hosting in the United States and the EU. In a broader sense, the establishment of the Foundation makes the ecosystem more robust by transferring core development to a more neutral entity. Thanks to its funding structure, the Foundation will be immune to various forms of pressure that for-profit companies are susceptible to.
Drive adoption of Sia
Although the overriding goal of the Foundation is to make Sia the best platform it can be, all that work will be in vain if no one uses the platform. There are a number of ways the Foundation can promote Sia and get it into the hands of potential users and developers. In-person conferences are understandably far less popular now, but the Foundation can sponsor and/or participate in virtual conferences. (In-person conferences may be held in the future, permitting circumstances.) Similarly, the Foundation will provide prizes for hackathons, which may be organized by community members, Nebulous, or the Foundation itself. Lastly, partnerships with other companies in the cryptocurrency space—or the cloud storage space—are a great way to increase awareness of Sia. To handle these responsibilities, one of the early priorities of the Foundation will be to hire a marketing director.
The Foundation Fund will be controlled by a multisig address. Each member of the Foundation's board will control one of the signing keys, with the signature threshold to be determined once the final composition of the board is known. (This threshold may also be increased or decreased if the number of board members changes.) Additionally, one timelocked signing key will be controlled by David Vorick. This key will act as a “dead man’s switch,” to be used in the event of an emergency that prevents Foundation board members from reaching the signature threshold. The timelock ensures that this key cannot be used unless the Foundation fails to sign a transaction for several months. On the 1st of each month, the Foundation will use its keys to transfer all siacoins in the Fund to two new addresses. The first address will be controlled by a high-security hot wallet, and will receive approximately one month's worth of Foundation expenditures. The second address, receiving the remaining siacoins, will be a modified version of the source address: specifically, it will increase the timelock on David Vorick's signing key by one month. Any other changes to the set of signing keys, such as the arrival or departure of board members, will be incorporated into this address as well. The Foundation Fund is allocated in SC, but many of the Foundation's expenditures must be paid in USD or other fiat currency. Accordingly, the Foundation will convert, at its discretion, a portion of its monthly withdrawals to fiat currency. We expect this conversion to be primarily facilitated by private "OTC" sales to accredited investors. The Foundation currently has no plans to speculate in cryptocurrency or other assets. Finally, it is important that the Foundation adds value to the Sia platform well in excess of the inflation introduced by the block subsidy. For this reason, the Foundation intends to provably burn, on a quarterly basis, any coins that it cannot allocate towards any justifiable expense. In other words, coins will be burned whenever doing so provides greater value to the platform than any other use. Furthermore, the Foundation will cap its SC treasury at 5% of the total supply, and will cap its USD treasury at 4 years’ worth of predicted expenses. Addendum: Hardfork Timeline We would like to see this proposal finalized and accepted by the community no later than September 30th. A new version of siad, implementing the hardfork, will be released no later than October 15th. The hardfork will activate at block 293220, which is expected to occur around 12pm EST on January 1st, 2021.
Addendum: Inflation specifics The total supply of siacoins as of January 1st, 2021 will be approximately 45.243 GS. The initial subsidy of 1.57 GS thus increases the supply by 3.47%, and the total annual inflation in 2021 will be at most 10.4% (if zero coins are burned). In 2022, total annual inflation will be at most 6.28%, and will steadily decrease in subsequent years.
We see the establishment of the Foundation as an important step in the maturation of the Sia project. It provides the ecosystem with a sustainable source of funding that can be exclusively directed towards achieving Sia's ambitious goals. Compared to other projects with far deeper pockets, Sia has always punched above its weight; once we're on equal footing, there's no telling what we'll be able to achieve. Nevertheless, we do not propose this change lightly, and have taken pains to ensure that the Foundation will act in accordance with the ideals that this community shares. It will operate transparently, keep inflation to a minimum, and respect the user's fundamental role in decentralized systems. We hope that everyone in the community will consider this proposal carefully, and look forward to a productive discussion.
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works. You can even run a node on a Raspberry Pi.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".
Where can I spend bitcoins?
Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins.
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
one bitcoin is equal to 100 million satoshis
1,000 per bitcoin
used as default unit in recent Electrum wallet releases
1,000,000 per bitcoin
colloquial "slang" term for microbitcoin (μBTC)
100,000,000 per bitcoin
smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

I've been sharing conspiracies on reddit longer than this sub has been around. I have a story to tell.
This story is mostly crafted from my own experiences, my conversations with some of the people involved, and the rest is my own guesswork as I try to fill in the gaps...so bear with me! That's why I wanted to share with this community, which I've watched grow over the years. I remember posting about the death of Barry Jennings (who witnessed explosions in the WTC on 9/11) the day after it happened. This was before /conspiracy (or right around when it was formed), and I remember thinking "we really need a sub for conspiracies on reddit!" And here we are, 12 years later and over 1.3 million subscribers...incredible! So... My story starts with a young man. We'll call him Andrew. Andrew grew up in the 90's in a coastal US town and quickly blossomed into a tech whiz at a young age. He began building his own computers, and after a brief stint using Windows, he decided that Bill Gates was everything wrong with technology (and the world), and he made it his mission to make sure folks like Gates were NOT the future of computers. He really believed that the use of technology was a fundamental human right, and that charging people for "proprietary" OS's that hid their source code was a violation of these rights. He saw a possible Deus Ex-like future, with a technocracy literally around the corner if we didn't act now. Andrew soon joined the Free Software Foundation and began rubbing elbows with the likes of Richard Stallman. He begun exclusively using GNU/Linux and was the type to correct you if you called it just "Linux". He also began visiting tech-savvy forums like slashdot and started networking in earnest. By 2006 (his senior year of high school) Andrew was completely over his "education" and decided to just drop out completely. Shockingly, a college accepted him anyway. A small East Coast school had been actively courting Andrew, and when they learned he had failed to get his HS diploma, they accepted him anyway! Now sometime during this period Andrew went to Iceland and stayed in Reykjavik for several months. This trip may have happened during the summer, fall, or early winter of 2006. The reason for his trip had something to do with his efforts in the FSF or similar group. The possible significance of this trip will become clear as we go on. What is clear is that Andrew started college in the fall of 2006, and that the circumstances were unusual. Andrew soon met several like-minded individuals and began building a social and technological network at his school. Two individuals in particular would become key players in his life (one more prominently in this story, but the other was significant as well), and eventually the 3 would live together in town for several years. But for now let's stick with Andrew. Andrew had an idea to build a social network for his college. Except, it wasn't just a network, it was a wiki for information about the school...and beyond. Soon, it began to morph into something much bigger in Andrew's mind. He saw his project as being one of many data "hubs" for leaks of important documents and otherwise sensitive information. So yeah, he saw the opportunity for a wiki for leaks (see where this is going yet...?). As his ambitions grew, his behavior started to become increasingly erratic. He was caught with drugs and arrested. Strangely, the charges were pretty much dropped and he was given a slap on the wrist. Eventually he decided to leave the school, but still lived in town and had access to the servers on campus. By 2010 Andrew was still living in the small town with his two "hacker" buddies, who were still enrolled at the school. This house was in some ways legendary. It appears that many "interesting" people spent time at or visited the residence. Indeed, some of the early movers and shakers of /conspiracy itself passed through. There was usually a full NO2 tank for anyone who was into that kinda thing, and they were stocked with every hallucinogen and research chemical known to man. It was also likely under surveillance by multiple intelligence agencies (NSA/Mossad/etc). Over time, the mental state of Andrew was slowly starting to deteriorate, which wasn't helped by his abuse of drugs. Still, Andrew decided to move his base of operations to Europe, spending time in Belgium, the Czech Republic and elsewhere. One of his housemates was soon to join him on his adventures in Europe and elsewhere abroad. We'll call him "Aaron." Aaron had a very similar story and upbringing as Andrew. Aaron was also from a coastal US town and was born into privilege. He was also, supposedly, born into a family with some serious connections to intelligence agencies, including an uncle with ties to the NSA, and both parents connected to military brass. By 2015, Andrew and Aaron were living together in the Czech Republic. During this time they were working directly and/or indirectly for the NSA (via Cisco and other companies). You see, the "college" they met at was actually a front for the recruitment of kids into the IC. Apparently, many "schools" in the US function that way. Go figure. Their intelligence and valuable skill set (hacking etc) made them valuable assets. They were also possibly involved with the distribution of certain "research chemicals" (of the 2C* variety) to dignitaries and their entourages (in one example, they provided 2CB to a group with David Cameron). In addition, Andrew was allegedly involved with, or stumbled upon, an NSA-linked surveillance project directed at the entire country of Malaysia, while Aaron was involved with Cisco. Aaron himself had gotten into hot water for releasing damaging information about the NSA, and even claimed to be an NSA whistleblower, and was also possibly the individual who leaked the 2014 (or 2015) Bilderberg meeting list. And then things went bad. Andrew quit the Malaysia project and Aaron left Cisco. It seems Andrew and Aaron were "set up" during a fiery false flag event in the Czech Republic in 2015. It may have happened at an embassy, but it's unclear which. There is no information on the web about anything like this (afaik). Aaron was immediately targeted and spent several years on the run. Allegedly, he was added to the list of victims in the so-called "Great Game". The Great Game is the term used for an international assassination program where intelligence agencies share a list of targets to be neutralized. The German BND and Mossad are heavily involved, as other networks. Individuals targeted by the Great Game may be offed by actual assassins, or by NPC-like humans whose minds will be influenced by mind control tech (a la Matrix...say influencing someone to ram your car unwittingly ie). As Aaron went on the lam, Andrew soon returned to the US, shell-shocked by his experience. Both Andrew and Aaron continue to suffer from some sort of PTSD from these series of events, rendering Andrew largely incapacitated and Aaron scattered and discombobulated. The Meat of the Matter OK...where does that leave us? Why am I sharing all of this? I think there's much more to this story. So let's start speculating! Everything I'm about to say is stuff that was told to me personally. I can't vouch for any of this information, though obviously I thought it was compelling enough to share. Here's the gist: The so-called whistleblowers you see in the media are almost all fake. This includes: Edward Snowden, Julian Assange, Thomas Drake and William Binney (hey look, his AMA is pinned on this sub right now...no comment!). These individuals, and others, are controlled opposition. The real whistleblowers are severely punished. For example, Bradley Manning was punished with chemical castration in jail. His "transformation" was chemically induced torture. Andrew was not alone in his passion. There were lots of other young visionaries like him who dreamed of a freer and more transparent world. In this story, Julian Assange was an intelligence asset...a psyop meant to steal the thunder from real activists like Andrew. In this story, a small college-based "wiki" for government leaks was used as the model for an intelligence operation known as "wikileaks". In this story, Andrew traveled to Iceland at some point in 2006. When was Wikileaks founded? Wikileaks was founded by Julian Assange in December 2006, in Iceland. Aaron discovered (legally, like Manning who had clearance to access all the data he leaked) damning information about surveillance happening by the NSA, specifically against recruits entering the US army and elsewhere. In this story, the "Andrew" identity was co-opted and turned into "Julian Assange", and "Aaron" became "Edward Snowden". Granted, there were probably other people that these whistleblower imposters were modeled after, but Andrew and Aaron seem like very strong contenders for some of this inspiration. Now, much of the following may be gobbledygook (lol I spelled that right first try!) for all I know, but since I'm having a really hard time making sense of it all, I'll just include everything I can and let you guys run with it. Here are some phrases, ideas, terms and people of note that may be involved with this story...MODS: None of this is doxing! All of the links of people are wikipedia pages or published interviews/articles. So yeah. Not dox!
Rootkit: These are currency and the weapons of the intelligence agencies that allow access to any computer or OS on the planet.
"schizo-affective disorder" doesn't exist, it's cover for EM warfare. For those they can't attack chemically (like Manning), they punish via EM. This technology has been used for decades. Both Andrew and Aaron were likely subjected to this punishment after they stopped playing ball. It likely continues for them both as well.
IN CONCLUSION I don't know how these terms, theories and individuals fit into this story, but that they may be somehow related. Hopefully there are enough bread crumbs in here to keep some of you busy! Any help/insight would be appreciated. I confess I'm not so tech-minded so I can't offer any more explanation about some of the more techy terms. Anyway, thanks for reading, and thanks for continuing to stimulate after all these years! It's really nice to see this place continuing to thrive after all of this time!
How YFI came out of nowhere to become the fastest coin to reach $1B and the fastest coin to ever get listed on Coinbase
Note: As mentioned to the original 624 Reddit subscribers, there will be $YFI based Exclusive Original Content released here by myself and others from time to time. These kinds of interactive Deep Dives with a Q&A with fellow Investors / Beta Testers right afterwards is a rare thing in Crypto, and will only be found with this level of immediacy, social interaction, permanence, depth, and complexity of analysis and feedback on a platform like Reddit. A lot of projects have low innovation, just copying something that someone else has already done, but with small tweaks to things like variables in Smart Contracts. A few rare projects have genuine innovation, providing genuine value to investors and users by providing attractive new products that simplify a lot of things in this space. Even rarer are the Unicorns that not only have innovation, but they have innovation in spades, oozing out of every pore. $YFI is one of these types of Unicorns. The scope of products and rapidity of release of new revolutionary products of this project has been simply unmatched in the short history of Crypto. Since 2009, the world of crypto has never seen anything like this lightning fast pace of development spanning such a wide scope of products - optimized automated yield farming and lending that relentlessly hunts the best yields, crypto insurance on Smart Contracts, a revolutionary Stablecoin idea that essentially makes a USD altcoin "smart" with built-in yield farming capabilities for the first time, to name a few - all built by a genius Smart Contract Builder who provided the world the first Fair Launch token. Key to wrapping your head around the advantages that the yEarn Finance ecosystem has over - well, every single other option out there at this time - are the concepts below:
CeFi vs. DeFi
Smart Contract Stacking
The power of a Talented and Diverse DAO
To discuss these concepts, and to educate beginners, we have to understand what the terms above truly mean. This post doesn't discuss any particular products and their advantages, only the systemic advantages that are available only to $YFI. This project seems to attract the smartest and the highest risk taking of crypto investors, and an important thing in truly understanding all of the risks involved, is that you have to know the terms and concepts first. Even veteran crypto and DeFi users may be thrown for a loop by some of the innovative products and concepts that keep coming out of the YFI Labs. This project is going through an expansion phase, where the scope of everything and the reach of the various released products is increasing (Insurance, A truly pegged Stablecoin, yETH Version 2, ySwap, yLiquidate, etc, etc..) You know that there's some motherforker or twenty that is now just avidly waiting for every piece of code that Andre drops onto GitHub, so that they can be among the first to copy it verbatim then claim it as "their own variation" because they changed some variables and titles. Yawn. From the definitive glossary for the DeFi space - yet another $YFI innovation - I'll list their definitions below. These may not be their final definitions when I finish any V1.1 edits to it, but they're good enough for now, and at least 3 or more YFI Dev Team members have read, reviewed, or edited these definitions. I've also invited my fellow Beta testers to provide comments to my RFC on this subreddit and in the Governance forum (among the documentation volunteers). Yes, this is how early DeFi investors are in the development and maturation of the DeFi space. Anyone reading this right now is so early into DeFi's evolution that the terms used for this space are literally still being finalized by the community. I've given a little bit of a sneak peek into how technical documentation is somehow self-organized in a powerful DAO such as this one. In this example, it starts off with a call for help on Twitter to improve our documentation by tracheopteryx. Interested and qualified volunteers show up (or don't) when such a call is made. Your writers and editors have spent many a moment pondering off into space debating whether this term really means this or that, or if the term was either succinctly described, or fully sufficient. It's a usually thankless and anonymous job, that is critical in providing enough relevant information to its users and investors. [Note: Just like anything you see related to the $YFI project: You can help us improve this documentation - any of it - if you see errors or better ways of describing this information.] All terms are shamelessly plagiarized from myself and my fellow writeeditors - u/tracheopteryx and Franklin - from the draft definitions in our new DeFi glossary: https://docs.yearn.finance/defi-glossary 1. CeFi vs. DeFi CeFi - Centralized Finance. In terms of cryptocurrency, CeFi is represented by centralized cryptocurrency exchanges, businesses or organizations with a physical address, and usually with some sort of corporate structure. These CeFi businesses must follow all applicable laws, rules, and regulations in each country, state, or region in which they operate. DeFi - DeFi, or Decentralized Finance, is at its root a set of Smart Contracts running independently on blockchains such as the Ethereum network. Smart Contracts may or may not interact with other smart contracts and even other blockchains. The goal of DeFi is to enhance profitability of investors in DeFi through automated smart contracts seeking to maximize yields for invested funds. DeFi is marked by rapid innovative progression and testing of new ideas and concepts. DeFi often involves high risk investing sometimes involving smart contracts that have not been audited or even thoroughly reviewed (a review is not as comprehensive as an audit, but may be also be included as part of an audit). Due to this and other reasons, DeFi is conventionally considered to be more risky than CeFi or traditional investing. Comment: DeFi is higher risk, partly because it moves so fast. A lot of yams, hot dogs, and sushi can get lost when you move so fast that you can't even bother to do a thorough audit before releasing code. The cream of the crop projects will all have had multiple audits done by multiple independent auditors. Auditors are expensive. At such an embryonic stage, most projects can't afford to have one audit done let alone 5. But if you can live with that higher risk intrinsic in DeFi and be willing to be a part of "testing in prod," then financial innovation can truly blossom. And if you let your best and brightest members of your community focus only on doing what they do best, then they don't have to bother to try to grow a business like a Bezos, Musk, or a Zuckerberg. Innovative entrepreneurs in this mold such as Andre, don't have to even try to do this business growth on their own because the DAO sets it up so that they don't have to do this.The DAO both grows the business while supporting and allowing these innovators to simply innovate, instead of trying to get nerds to do backroom deals to gain market share and access to new customers. It turns out that nerds are much more productive when you just let them be a nerd in their labs.
Composability - The measure of the usability and ability of a product to be used as a building block (or "money lego") in the construction of other products or domains. A protocol that is simple, powerful, and that functions well with other protocols would be considered to have high composability. Comment: The maturity of the cryptocurrency ecosystem and the evolution of composable building tools in the DeFi space now make new products and concepts available. $YFI would not have been possible only 2 or 3 years ago; the tools and ecosystem simply weren't ready for it yet. This is why only now are you and many other now hearing about YFI. In 2018, Andre began providing free code reviews to Crypto Briefing. Andre had to learn to walk before he could run, and the composable tools needed to work on embryonic ideas in his head were simply not ready or available then. By reading and reviewing so many Smart Contracts he learned to recognize good code from bad code at what was still a very early stage in Smart Contract development in 2018, only 3 years after ETH's launch in July 2015.
Smart Contract Stacking
Smart Contracts - A digital contract that is programmed in a language that is considered Turing complete, meaning that with enough processing power and time, a properly programmed Smart Contract should be able to use its code base and logical algorithms to perform almost any digital task or process. Ethereum's programming languages, such as Solidity and Vyper, are Turing complete. Comment: Smart Contracts have actually gotten smarter since ETH launched in July 2015. It's because Smart Contract builders needed to learn Solidity and how it functions and interoperates before they could spread their wings as designers. With more time and experience under their belts, the early SC builders that stuck to it have gotten much better. In Andre Cronje, we may have been witness to the rise of the next Satoshi or Vitalik of crypto. There is a reason that a couple of days ago, I counted 6 of 41 YF clones - nearly 15% - among the top gainers on the day. Success breeds copycats showing a ton of flattery. A smart contract is so smart, it can be used to be stacked upon other smart contracts such as at Aave or Maker. True innovation takes time, sacrifice, blood, sweat, and tears. It does not come without cost to those doing the innovating. There is not a single project in DeFi, CeFi, or even all of cryptocurrency that can claim the breadth and diversity of innovation and product reach that is found in the $YFI ecosystem. As a tech investor and professional nerd who's been involved at Research Labs and around product development and testing since before the year 2000. Prior to that I've ready widely and keenly to keep up with technological changes and assess investment potential in these disruptive changes nearly my whole life. The amount of innovation shown in this project is breathtaking if you're a Tech or FinTech researcher. It's being released at a ridiculously rapid pace that is simply unmatched in any private or government research lab anywhere, let alone at any CeFi or traditional financial institution one can name. The only comparable levels of innovation shown by this young project is typically only seen during periods of epochal changes such as The Renaissance or times of strife and war, such as World War II. Unless you've been in the industry and working with coders:I don't think those that haven't been around software development and testing can understand, can truly grasp that no one, no group does this.This isn't normal. This rapid-fire release of truly innovative code and intelligent strategies would have to be comparable to some of the greatest creative periods of human ingenuity and creativity. It's truly on par with periods of brilliance seen by thinkers like Newton, Einstein and Tesla, except with software code and concepts in decentralized finance. When the history of FinTech writes this chapter in its history, $YFI may need its own section or chapter. Don't forget all of these financial instruments we take for granted all around us, all had a simple start somewhere, whether it was an IOU system of credit, insurance, stocks, bonds, derivatives, futures, options, and so on...they all started off as an idea somewhere that had to get tested sooner or later "in production." One brilliant aspect of $YFI Smart Contracts is that they're built as a profitable layer atop existing DeFi protocols, extracting further value from base crypto assets and even primary crypto derivatives. $YFI is built atop existing smart contracts to create further value where there was none before, and help maximize gains for long term investors.
The Power of a Talented and Diverse DAO
DAO - Distributed Autonomous Organization. The first DAO was started in 2016. According to Wikipedia's definition, it is an: "organization represented by rules encoded as a computer program that is transparent, controlled by the organization members and not influenced by a central government. A DAO's financial transaction record and program rules are maintained on a blockchain." When implemented well, a DAO allows for real world experiments in decentralized democratic organization and control, with more freedom of action and less regulatory oversight for DAO controlled projects and products when compared to legacy corporate structures and organizations. Comment: yEarn Finance has shown us what a properly motivated and sufficiently powerful DAO can do in a short amount of time. There's many reasons why this project with an already profitable business model is the fastest original project in history to ever reach a $1B marketcap in any market - traditional or crypto - accomplishing this amazing feat in less than two months. There's reasons why this is probably the fastest coin in history to get listed on Coinbase in less than 2 months. The power of a sufficiently talented and diverse development team and community is stunning in its power, speed, and ability to get things done quickly. There are risks aplenty with parts of this project, but $YFI is now seen as a "safe" place in DeFi, because you know you that as far as yield farming you probably couldn't do it better yourself unless you took a chance on unaudited code with anonymous Devs, or you were doing the trading equivalent of throwing darts blindfolded and somehow won, except that you even more improbably kept doing that over and over and winning. Summary: There's reasons why YFI has been called the Bitcoin of DeFi and the Berkshire Hathaway Series A of crypto. I've listed some of the reasons above. The confluence of these 4 factors has helped lead to explosive growth for this project. This isn't financial advice as I'm not a financial pro but make no mistake: as a Crypto OG around crypto since early 2013, who was deeply involved in multiple community projects as an early organizer, and who was a small investor during the DotCom era investing in early giants that went on to be gorillas, I don't say this lightly that the $YFI project is lightning in a bottle and a diamond in the rough. What $YFI allows, when all is said and done, is the rapid fire implementation of great ideas that have gone through a rapid Darwinian evolution, where only the best ideas are implemented. Thoughts and ideas are powerful things. The valuation of this coin and ecosystem has to, itmusttake into account that this nascent financial innovation hub and ecosystem actually works and allows the best of these ideas to actually blossom rapidly. You just don't find too many gems like this.
I thought I'd write about the last four years, an eventful time for Bitcoin and me. For those who don't know me, I'm Hal Finney. I got my start in crypto working on an early version of PGP, working closely with Phil Zimmermann. When Phil decided to start PGP Corporation, I was one of the first hires. I would work on PGP until my retirement. At the same time, I got involved with the Cypherpunks. I ran the first cryptographically based anonymous remailer, among other activities. Fast forward to late 2008 and the announcement of Bitcoin. I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it. When Satoshi announced Bitcoin on the cryptography mailing list, he got a skeptical reception at best. Cryptographers have seen too many grand schemes by clueless noobs. They tend to have a knee jerk reaction. I was more positive. I had long been interested in cryptographic payment schemes. Plus I was lucky enough to meet and extensively correspond with both Wei Dai and Nick Szabo, generally acknowledged to have created ideas that would be realized with Bitcoin. I had made an attempt to create my own proof of work based currency, called RPOW. So I found Bitcoin facinating. When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them. Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs. After a few days, bitcoin was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me. In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there at the beginning. It's one of those glass half full half empty things. The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there. As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they'll be worth something to my heirs. Speaking of heirs, I got a surprise in 2009, when I was suddenly diagnosed with a fatal disease. I was in the best shape of my life at the start of that year, I'd lost a lot of weight and taken up distance running. I'd run several half marathons, and I was starting to train for a full marathon. I worked my way up to 20+ mile runs, and I thought I was all set. That's when everything went wrong. My body began to fail. I slurred my speech, lost strength in my hands, and my legs were slow to recover. In August, 2009, I was given the diagnosis of ALS, also called Lou Gehrig's disease, after the famous baseball player who got it. ALS is a disease that kills moter neurons, which carry signals from the brain to the muscles. It causes first weakness, then gradually increasing paralysis. It is usually fatal in 2 to 5 years. My symptoms were mild at first and I continued to work, but fatigue and voice problems forced me to retire in early 2011. Since then the disease has continued its inexorable progression. Today, I am essentially paralyzed. I am fed through a tube, and my breathing is assisted through another tube. I operate the computer using a commercial eyetracker system. It also has a speech synthesizer, so this is my voice now. I spend all day in my power wheelchair. I worked up an interface using an arduino so that I can adjust my wheelchair's position using my eyes. It has been an adjustment, but my life is not too bad. I can still read, listen to music, and watch TV and movies. I recently discovered that I can even write code. It's very slow, probably 50 times slower than I was before. But I still love programming and it gives me goals. Currently I'm working on something Mike Hearn suggested, using the security features of modern processors, designed to support "Trusted Computing", to harden Bitcoin wallets. It's almost ready to release. I just have to do the documentation. And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go. That's my story. I'm pretty lucky overall. Even with the ALS, my life is very satisfying. But my life expectancy is limited. Those discussions about inheriting your bitcoins are of more than academic interest. My bitcoins are stored in our safe deposit box, and my son and daughter are tech savvy. I think they're safe enough. I'm comfortable with my legacy.
Part 1Part 2 I'm at $BigClient, which is taking a Citroen like approach to infrastructure and operations. "We recognize that the McPherson strut is simple, efficient, good enough for most use cases and accepted by everyone in the industry, but we shall do it with hydraulic fluid at high pressure. What could go wrong?" Except $BigClient's far away from a competent Citroen shop. $BigClient's Citroen has gone through a few years of 'just keep it running on the cheap' upkeep without access to factory parts. I've got an odd patching problem on a handful of servers. Systems are rolling back to insecure versions (2.0.2 ->1.4.6) and nobody knows why. Or at least, nobody's talking. I don't know what to do yet, so I decide to go and get lunch. I work out the possibilities.
There's something wrong with our validation procedure- they're actually patched and we're reading the wrong thing.
There's something or someone else downgrading these systems.
Number 1 requires more documentation, which $BC doesn't seem to want to show me. Number two might be hiding in logs, which are emailed to me on a regular basis. I walk back to my cubicle, grab my laptop and a notebook and find a quiet corner to figure things out. I find one in a tiny conference room. I read through my emails and search for any of the logs from the api servers. I spend about ten minutes on Stack Exchange for the appropriate sed, awk, tee and cat munging to pare them down to what I want. Eventually I dump them all to Excel, because I am a bad person. Some filtering and I can see what's going on. The system orchestration updates each server every other midnight. I see about three quarters of them download the 2.0.2 version as a part of the night's update. Every two nights a (seemingly) random selection of servers updates. I scribble the order on the conference room whiteboard and stare at them for a few minutes. Nothing in the orchestration system logs shows another process loading the older 1.4.6. version. But something is. Nothing in the logs emailed to me obviously points to another process. I take a walk to get a coffee and think. Nothing comes to me and I have to scour the kitchen for unflavored coffee. I walk back to my conference room to find an intern-like person. me:"Hey, I apologize. I didn't know the room was reserved. I'll take my stuff." Other person:"That's ok. Are you Rob?" me:"Nope, sorry" I take my stuff and make my way back to my cubicle. A few minutes searching leads me to a shared root password for the servers stored in the password vault. I login to one of the remaining servers running 2.0.2 and look at the running processes. Nothing obvious like "random updater". I'm stumped. I lean back and stare at nothing in particular trying to come up with some ideas. Unfortunately, it's fairly packed and I'm next to a bullpen. Voice 1:"So the Sky Caps put blotter in the vat without telling anyone" Voice 2:"Hilton Honors kicks' Marriott Bonvoy's ass any day." Voice 3:"No, I'll pick her up at 4" The voices wash over me in some clip reel workplace sitcom haze. I'm not going to get anything done. I take a walk around the offices to get the lay of the land. It's a Hanna-Barbera cartoon of grey cubefarms, tan breakrooms, free coffee but no snacks. The only attempts at color are people's cubicles. Family pictures, shirtless men with fish, desk toys and action figures. It's like a mall- everything's pleasant, non threatening and in identically-sized stalls, with colorful (but bounded) individuality, all for commerce. Then I find the Hot Topic meets Successories manifesting in a cubicle. There are two dorm-room sized posters of the gold Bitcoin-coin, along with framed inspirational quotes about success and perserverance set against pictures of Game Of Thrones characters and muscle-bound men in insignia-less camo. A new leather jacket with an embroidered skull is on the back of the chair. This person is either a hoot or insufferable. I keep walking. I have a breakthrough. Where are the API servers getting the older version to install? Maybe that'll lead me into the library. I'm not yet Adso, but perhaps I'm one of the other ,lesser scribes copying my book and scribbling fanciful drawings of the things I miss, like decent coffee and a cell-mate that doesn't snore. I walk back to my cubicle. A different intern-shaped person is in the conference room, all alone. I can't save them. Eventually they'll be standing in the corner of their cubicle looking away while the middle manager cleans out the rest of their team. I'm in my seat. Some searching results in a few possible repositories. Some more searching finds me the one repo that still has v1.4.6 of this application. Just to make sure, I compare a downloaded copy of v1.4.6 and the installed version of v 1.4.6 on one of the servers. I search all the folders and files for the URL of the repo server and find it. In the application itself. The server waits every two days and looks to the repo. If the installed version is not equal to v 1.4.6, it downloads v 1.4.6 from the server and installs it, then forces a restart. This code is commented out (made non-executable) along with an actual comment: /REMOVE BEFORE PRODUCTION I quickly scan through the API servers to find one of the ones still running 2.0.2. I search for the term "REMOVE BEFORE PRODUCTION" And there it is, in the application code. Except it's not commented out. In a text editor, I write up my findings, conclusion and a recommended fix- delete the upgrade code snippet, increment to 2.0.3, push it out using the orchestration tool and call it a day. LC Chat won't let me attach my text file, so I breathlessly LC Chat my document, line by line at Vincent, the poor bastard tasked with closing audit finding 162, the mystery of the random rollback. Vincent:... Clearly, Vincent is choosing his congratulatory language carefully. Vincent:"Can't apply the fix. The application is owned by Development. They're behind on other things, so they won't update the software until next quarter." me:"It's about thirty lines of code we can comment out" Vincent:"Can we say it's fixed for the audit since we know what the problem is?" me:"No. We can patch it, or we could write up a remediation plan and get it on some schedule." me:"But that's more paperwork than the actual fix." Vincent:"But Ops isn't on good terms with Development." me:"So they're not going to touch it any time soon." Vincent:"Probably not" me:You guys own that repo server, too" Vincent:"I don't see how that's good for anything" me:"We cut out the update code in 2.0.2 and call it 2.0.3. We name the file 1.4.6 and replace the existing 1.4.6 on the repo server. Either the app gets updated via your orchestration server or it updates itself. We're fixed in two days either way. Vincent:"But policy requires that we get approval" me:"There's an exception, if you have a superior in Operations to sign off, you can call it an emergency fix. Ask Trevor. He just needs to not tell anyone else. You submit the ticket and eventually the devs will get to it and fix the problem for good. Until then, you pass that part of the audit." Vincent tells me he's going to talk to Trevor. I'm going to take a walk. Out of curiosity, I go back to the Hot Topic cubicle to get a look at its occupant. The jacket is gone and the monitors are off. Mystery person has left for the day, I assume. I look at the large jars of nutritional supplements with macho names- Gorilla Rage, LumberJacked, Psycho Focus". I notice the name-plate on the outside of the cubicle. Oh, no. Ian. To Be Continued... edit- made modifications to satisfy Internal Audit 8-)
Syscoin Platform’s Great Reddit Scaling Bake-off Proposal
https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44 We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution! Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality. Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining. This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.
Syscoin + Matic Integration
Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both. Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Total cost for these 100k transactions: $0.63 USD See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing: ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37) Syscoin price: $0.11 Snapshot of live fee comparison chart Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions. Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.
Tools to simplify using Syscoin Bridge as a service with dapps and wallets will be released some time after implementation of Syscoin Core 4.2. These will be based upon the same processes which are automated in the current live Sysethereum Dapp that is functioning with the Syscoin mainnet.
The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms. The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).
Unique fee-market that is more efficient for microtransaction redemption and settlement
Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
Provides high throughput and secure fulfillment even if blocks are full
Probabilistic and interactive
99.9999% security assurance within 10 seconds
Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus
Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.
Syscoin 3.0 White Paper (4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
SHA256 merge mined with Bitcoin
UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
Z-DAG on asset layer, bridge to Ethereum on asset layer
On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.
Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask. Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2. Current supported wallets Syscoin Spark Desktop Syscoin-Qt
Pretty sure a family member of mine is being scammed via a trading/bitcoin site?
Basically an older member of my family read up about bitcoin, specifically a news article about a guy who invested £250 and 2 weeks later it turned into thousands of pounds so he very hastily signed up to a site called onlinemarketshare.com and deposited £250, It required him to upload some documents and personal ID, along with a picture of his bank card luckily with alot of the sensitive info blacked out, He then got phone calls daily who I presume was the stock broker? He isn't computer savvy at all so she got him to download some software that lets her access his computer remotely (i know wtf) Looks to me though that he has to give her a code before she connects and he can disconnect her at any point?? Anyway she will talk him thorugh where his money goes, pulling up charst and such, I think he said she could only invest 15% a day or something like that, Anyway she called him today asking him to invest more ($2000) he got cold feet and has tried to withdraw his money, However he can't just withdraw it, its come up as 'withdraw pending' and that a manager would phone him?? Eventually someone phoned from a completely different site called Active Brokerz looking for bank details, He was smart enough not to give anything to which he got in touch with me, after a quick google of Active Brokerz first thing that comes up is scam site, There's quite a few red flags that the whole thing is a scam, Whats throwing me is that he got the link to the site from a news article after he signed up for the news letter, surely a news website wouldn't link a dodgy site? However if it is a scam, what should our next steps be?
Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Overview We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too! Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know). To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts. 1.1 Why Ethereum Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract. The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both. Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice. 1.2 Why Arbitrum While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools. Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users. We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth. 2. Arbitrum at a glance Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes. Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability. Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow. Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below. Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn. Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask. Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract. Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details). Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users. Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum. Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain. Limitations Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals. As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit). Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here). So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality. 3. The recipe: How Arbitrum Rollup works For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents: Arbitrum Rollup Whitepaper Arbitrum academic paper (describes a previous version of Arbitrum) 4. Developer docs and APIs For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/. Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release. 5. Who are the validators? As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators? Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers. Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators. 6. Reddit Contract Support Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain. Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain. For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2. Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios. In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process. To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum. When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) . The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform. 8. Benchmarks and costs In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking. Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here. Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum. On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support: Over a 5 day period, your scaling PoC should be able to handle:
100,000 point claims (minting & distributing points)
75,000 one-off points burning
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.) We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks). Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c. We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic. Our model. Our cost model includes several sources of cost:
L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system. Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.) 9. Status of Arbitrum Rollup Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade. Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet. 10. Reddit Universe Arbitrum Rollup Chain The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo. If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access. 11. Even more scaling: Arbitrum Sidechains Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide. While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic. The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout. Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator. Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol. Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest. We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help. While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined). 12. How Arbitrum compares We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects. Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components. But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.
