Dragonchain Great Reddit Scaling Bake-Off Public Proposal

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 posts per 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 on YouTube.
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.

Executive summary

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.

Live Demo

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

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.

Scaling

How it works & scales

Architectural Scaling

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.

Economic Scaling

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.

Scaled Deployment

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

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

Getting Started

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...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
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.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • 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.

Requirements

Scaling

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

Decentralization

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 multi-cloud
  • 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.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. 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).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

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

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

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

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

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.

Dragon Den

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
See above

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.

Other Considerations

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).

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

Open Source

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
  • Preferred license
  • 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.

Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol

  1. SUMMARY
Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.
  1. KEY CONCEPTS

  1. REVENUE MODEL
A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:

6 Reasons Why Serum Won't Succeed

6 Reasons Why Serum Won't Succeed

The world of DeFi is exploding but is it all it’s made out to be?

DeFi (decentralised finance) is most certainly the buzz in the crypto world this minute. It’s bringing similar feelings which was the 2017/18 ICO phase, where a mammoth of new projects begun to explode onto the scene, each with their own promise of new innovation and use case.
Hindsight has shown us that most of those projects have ultimately failed, or worse, were outright scams that took advantage of not so wise investors looking to make a buck. Obviously, not all projects fit that description, with many teams still around today working on and delivering their individual visions. Crypto is, after all, still a big experiment of new technology.

Enter DeFi: Serum

DeFi has exploded into the limelight over the last few months, with some tokens appreciating hundreds of percent in price. It appears to be the catalyst that has driven a huge market shift in the crypto world, and for those who’ve been around a number of years, this is a welcome change.
In this piece, I’m going to examine a particular project called Serum.
Serum is the world’s first completely decentralized derivatives exchange with trustless cross-chain trading brought to you by Project Serum.
The Serum Project is aiming to create both a decentralised exchange and a cross-chain swapping mechanism. In this article, I’m going to focus solely on the cross-chain swapping aspect of Serum.
Although the Serum whitepaper is quite short and lacking in detail, it is useful to derive some understanding of how the cross-chain swapping protocol should work. Throughout this review, I will use it to describe how the imagined protocol works.

Overview

Let's assume Alice wants to trade some BTC for ETH and Bob wants to trade some ETH for BTC using Serum. These two users are matched and agree on a price using an on-chain order book on the Solana blockchain (whitepaper provides no practical details on how to do this).
Once these users are matched, Bob must send the ETH he wants to trade to an Ethereum smart contract, plus some amount of ETH ~200 USD worth (see section 4 below) to the smart contract as collateral. Alice will also need to send some collateral to the smart contract. Once this initial setup process is complete Alice then has to send her BTC to Bob’s BTC address and if Bob receives the BTC from Alice he can then release his ETH from the smart contract sending it to Alice’s ETH address. Upon completion of this both Alice and Bob are refunded their ETH collateral.
So what happens if something goes wrong? For example, say Alice never sends BTC to Bob, after some period of time Bob can initiate a dispute. When the dispute begins both Alice and Bob present a portion of the Bitcoin blockchain information to the smart contract (see section 3). The smart contract then decides whether or not Alice did send BTC to Bob. If she hasn’t then the smart contract returns Bob's ETH and collateral to Bob and also takes Alice’s ETH collateral and gives that to Bob. The same occurs in reverse if Alice sends BTC but Bob never approves the transfer of ETH from the smart contract.
This scheme seems pretty simple, there’s no oracles and no centralised parties, however, it has a number of disadvantages.

1. User-Provided Collateral Is Bad for User Experience

Each time a user conducts a swap they must reserve some percentage or fixed amount to cover the collateral for the swap. This collateral amount needs to be present to prevent griefing attacks where users initiate swaps with no intention of ever following through and sending funds to the alternate participant.
However, this creates a poor user experience as both Alice and Bob need to have at least the value of the dispute fee committed to the contract in collateral before they conduct a swap. This is totally foreign from the normal exchange experience in which you only require a single coin and a single transaction to begin trading. For example, if using Serum to trade Bitcoin you would need to hold Bitcoin and ~200$ of Ethereum and also interact with the Ethereum chain before any swap occurs. This adds unnecessary complexity and confusion, especially for newcomers to the crypto space.

2. ETH Must Always Be on One Side of the Swap

Although the Serum method of cross-chain swapping could occur on any blockchain with smart contracts, the Serum whitepaper makes it clear the Serum arbitration contract is going to be deployed on the Ethereum blockchain. This means one party must always be locking the full value of the trade in ETH using an Ethereum smart contract.
This makes it impossible, for example, to do a single step trade between Bitcoin and Monero since the swap would need to be from Bitcoin to ETH first and then from ETH to Monero. This is comparable to other proposed cross-chain swap systems like Thorchain and Blockswap, however since those networks use AMM’s (automated market makers)and decentralized vaults to take custody of funds, the user needs not to interact with the intermediary chain at all.
Instead in Serum, the user wanting to swap Bitcoin to Monero will need to do the following steps:
  1. Send Ethereum collateral to the Serum arbitration contract
  2. Send Bitcoin to the user they are swapping with.
  3. Receive Ethereum
  4. Send Ethereum back to Serum arbitration contract
  5. Receive Monero
  6. Send Ethereum out of Serum arbitration contract
  7. Receive back Ethereum collateral
It might be possible to remove or simplify step 4, depending on how the smart contract is built, however, this means a swap from BTC to Monero would require 2 Ethereum and 1 Bitcoin transaction in the best-case scenario. Compared with the experience of other cross-chain swapping mechanisms, which only require the user to send a single transaction to swap between two assets, this is very poor user experience.

3. Proving Transactions on Arbitrary Chains to a Smart Contract Is Not Trivial

Perhaps the most central part of the Serum cross-chain swapping mechanism is left completely unexplored in the Serum whitepaper with only a brief explanation given.
“[The] Smart Contract is programmed to parse whether a proposed BTC blockchain is valid; it can then check which of Alice and Bob send the longer valid blockchain, and settle in their favor”
This is not a trivial problem, and it is unclear how this actually works from the explanation given in the Serum whitepaper. What actually needs to be presented to the smart contract to prove a Bitcoin transaction? Typically when talking about SPV the smart contract would need the block headers of all previous blocks and a merkle inclusion proof. This is far too heavy to submit in a dispute. Instead, Serum could use NIPoPoW, however, these proofs only work on chains with fixed difficulty and are still probably prohibitively too large (~100KB) to be submitted as a proof to a contract. Other solutions like Flyclient are more versatile, but proof sizes are much larger and have failed to see much real-world adoption.
Without explaining how they actually plan to do this validation of Bitcoin transactions, users are left in the dark about how secure their solution actually is.

4. High Dispute Fees Force Large Collateral on Small Trades

Although disputes should almost never happen because of the incentives and punishments designed into the Serum protocol, the way they are designed has negative impacts on the use of the network.
Although the Serum whitepaper does not say how the dispute mechanism works, they do say that it will cost about ~100 USD in GAS to dispute a swap.
Note: keep in mind that the Serum paper was published in July 2020 when the gas price was about 50 Gwei, as Ethereum use has picked up over the past month we have seen average GAS prices as high as 250 Gwei, with the average price right now about 120 Gwei.
This means that at the height of GAS prices it could have cost a user ~500 USD to dispute a swap.
This means for the network to ensure losing cross-chain swaps aren’t made each user must deploy at least $200 in collateral on each side. It may be possible to lower this to collateral if we assume the attacker is not financially motivated, however, there is a lower bound in which ransom attacks become possible on low-value trades.
Further and perhaps more damagingly, this means in a trade of any size the user needs to have at least 300 USD in ETH laying around. 100 USD in ETH for the required collateral and 200 USD if they need to challenge the transaction.
This further adds to the poor user experience when using Serum for cross-chain swapping.

5. Swaps Are Not Set and Forget

Instead of being able to send a transaction and receive funds on the blockchain you are swapping to, the process is highly interactive. In the case where I am swapping ETH for Bitcoin, the following occurs:
If the Bitcoin transaction is never received then I need to wait for a timeout to occur before I can participate in the dispute process.
And on the Bitcoin side (assuming the seller is ready), the following must take place:
If the Seller never accepts the Bitcoin I sent to him then I need to wait on line for the dispute process.
This presents a strange user experience where the seller or seller’s wallet must be left online during this whole process and be ready to sign a new transaction if they need to dispute transactions or unlock funds from a smart contract.
This is different from the typical exchange or swapping scenario in which, once your funds are sent you can be assured you will receive the amount you expected in your swap back to you, without any of your wallets needing to remain online.

6. The Serum Token Seems to Lack a Use Case

The cross-chain swapping protocol Serum describes in its whitepaper could easily be forked and launched on the Ethereum blockchain without having any need for the Serum token. It seems that the Serum token will be used in some capacity when placing orders on the Solana based blockchain, however, the order book could just as easily be placed off with traditional rate-limiting schemes.
There is some brief mention of future governance abilities for token holders, however, as a common theme in their whitepaper, details are scarce:
Serum is anticipated to include a limited governance model based on the SRM token. While most of the Serum ecosystem will be immutable, some parameters without large security risks (e.g. future fees) may be modified via a governance vote of SRM tokens.

Conclusion

Until satisfactory answers are given to these questions I would be looking at other projects who are attempting to build platforms for cross-chain swaps. As previously mentioned, Thorchain & Blockswap show some promise in design, whilst there are some others competing in this space too, such as Incognito and RenVM. However, this area is still extremely immature so plenty of testing and time is required before we can call any of these projects a success.
If you’ve got any feedback or thoughts about Serum, cross-chain swapping or DeFi in general, please don’t be shy in leaving a comment.

4. Transaction Fees

Transferring funds across the blockchain and withdrawing them from Bittrex costs a fee for customers, with the rate unique for every coin.
Bittrex Global charges no commission for deposits. Please keep in mind that some tokens or cash may be required to perform a transaction by a crypto coin or token’s community. Bittrex crypto exchange can’t keep away from it.
Every token or coin has a blockchain transaction fee that is built in it, and the Bittrex fee is a small amount to cover this charge. You can view the fee percentage for every coin or token by clicking Withdrawal near to the coin. There you will see a transaction fee you will be charged for withdrawing a specific coin or token.
In the example below, the withdrawal fee amounts to 1 USDT

Trading expenses are incurred when an order is prepared by means of the Bittrex worldwide matching engine. While an order is being executed, the purchaser and the vendor are charged a rate primarily based on the order’s amount. The fee charged by Bittrex exchange is calculated by the formula amount * buy rate * fee. There aren't any charges for placing an order which is not being executed so far. Any portion of an unfinished order will be refunded completely upon order cancelation.
Prices vary depending on the currency pair, monthly trade volume, and whether the order is a maker or taker. Bittrex reserves the right to alternate fee quotes at any time, including offering various discounts and incentive packages.

Monthly Volume

Your buying and selling volume affects the fee you pay for every order. Our expenses are built to encourage customers who ensure liquidity in the Bittrex crypto exchange markets. Your buying and selling charges are reduced according to your trade volume for the last 30 years in dollars.
Bittrex calculates the 30-day value every day, updating every account's volume calculation and buying and selling charge between of 12:30 AM UTC and 01:30 AM UTC every day.
You can check your monthly trade volume by logging in and opening Account > My Activity.

6. Withdrawing Funds

Withdrawing any type of funds is likewise simple. You can profit by buying and selling Bitcoin, Ether, or any other cryptocurrency.
You determine the crypto address—to which the amount will be credited—and the transaction amount. The withdrawal fee will be automatically calculated and shown right away.
After confirming the transaction, the finances will be sent to the specified addresses and all that you need to do is to wait for the community to confirm the transaction.
If the 2FA is enabled, then the user receives a special code (via SMS or application) to confirm the withdrawal.

7. How to Trade on Bittrex Global

Currency selling and buying transactions are performed using the Sell and Buy buttons, accordingly.
To begin with, the dealer selects a currency pair and sees a graph of the rate dynamics and different values for the pair.
Below the chart, there is a section with orders where the user can buy or sell a virtual asset.
To create an order, you just need to specify the order type, price, and quantity. And do not forget about the 0.25% trade fee whatever the quantity.
For optimum profit, stay with liquid assets as they can be quickly sold at a near-market rate effective at the time of the transaction. Bittrex offers no referral program; so buying and selling crypto is the easiest way to earn.

Order Types

Bittrex helps you alternate Limit and Stop-Limit orders.
A limit order or a simple limit order is performed when the asset fee reaches—or even exceeds—the price the trader seeks. To execute such an order, it is required that there's a counter market order on the platform that has the identical fee as the limit order.

Differences between Limit Order and Stop Limit Order

A stop limit order is a mixture of a stop limit order and a limit order. In such an application, charges are indicated—a stop charge and the limit.

Stop Limit Order Purpose

https://preview.redd.it/hlxvy9ti4zh51.jpg?width=1141&format=pjpg&auto=webp&s=064a77459a4dcb4555a885cbc56629aae10fc38b

Trade Terminal

Let’s discuss how you could trade conveniently with our service.
The key features include a user-friendly interface and precise currency pair statistics (timeframe graphs, network data, trade volumes, and so forth).
The platform’s top-notch advantage is handy, easy-to-analyze, customizable charts. There is also a column for quick switching between currency pairs and an order panel beneath the fee chart. Such an all-encompassing visual solution helps compare orders efficiently and in one place.
You can use the terminal in a day or night mode; when in the night mode, the icon in the upper-right corner changes and notice the Bittrex trading terminal in night mode is displayed. The main menu consists of 4 sections: Markets, Orders, Wallets, Settings.
Markets are the trade section. Bittrex allows handling over 270 currency pairs.
Orders. To see all open orders, go to OrdersOpen.
To see completed orders, go to OrdersCompleted.
Wallets. The Wallets tab displays many wallets for all cryptocurrencies supported by the exchange and the current balance of each of them.
After refilling the balance or creating a buy or sale order, you will see all actions in the section. Bittrex allows creating a separate wallet for every coin. Additionally, you can see how the coin price has changed, in terms of percentage, throughout the day.
Here’s what you can also do with your wallets:
  • Hide zero balances: hide currencies with zero balance
  • Green and red arrows: replenish balance/withdraw funds
  • Find: search for a cryptocurrency
The Settings section helps manage your account, verification, 2FA, password modification, API connection, and many more.

How to Sell

The process of selling crypto assets follows the same algorithm. The only difference is that after choosing the exchange direction, you need to initiate a Sell order. All the rest is similar: you select the order type, specify the quantity and price, and click Sell *Currency Name* (Sell Bitcoin in our case).
If you scroll the screen, the entire history of trades and orders will be displayed below.

LONG and SHORT

You can make a long deal or a short deal. Your choice depends on whether you expect an asset to fall or rise in price.
Long positions are a classic trading method. It concerns purchasing an asset to profit when its value increases. Long positions are carried out through any brokers and do not require a margin account. In this case, the trader’s account must have enough funds to cover the transaction.
Losses in a long position are considered to be limited; no matter when the trade starts, the price will not fall below zero with all possible errors. Short positions, in contrast, are used to profit from a falling market. A trader buys a financial instrument from a broker and sells it. After the price reaches the target level, the trader buys back the assets or buys them to pay off the initial debt to the broker.
A short position yields profit if the price falls, and it is considered unprofitable the price matches the asset value. Performing a short order requires a margin account as a trader borrows valuable assets from a broker to complete a transaction. Long transactions help gain from market growth; short from a market decline.

Trade via API

Bittrex also supports algorithmic trading through extensive APIs (application programming interface), which allows you to automate the trading process using third-party services.
To create an API key, the user must enable the two-factor authentication 2FA, verify their account, and log in to the site within 3 minutes.
If all the requirements of the system are fulfilled, you can proceed to generate the API key. Log in to your Bittrex account, click Settings. Find API Keys. Click Add new key (Create a new key).
Toggle on / off settings for READ INFO, TRADE, or WITHDRAW, depending on what functionality you want to use for our API key.
Click Save and enter the 2FA code from the authenticator → Confirm.
The secret key will be displayed only once and will disappear after the page is refreshed. Make sure you saved it!
To delete an API key, click X in the right corner for the key that you want to delete, then click Save, enter the 2FA code from the authenticator and click Confirm.

Bittrex Bot, a Trader’s Assistant

Robotized programs that appeared sometimes after the appearance of cryptocurrency exchanges save users from monotonous work and allow automating the trading process.
Bots for trading digital money work like all the other bots: they perform mechanical trading according to the preset parameters.
Currently, one of Bittrex’s most popular trading bots is Bittrex Flash Crash Buyer Bot that helps traders profit from altcoin volatility without missing the right moment.
The program monitors all the market changes in the market every second; also, it even can place an order in advance. The Bittrex bot can handle a stop loss—to sell a certain amount of currency when the rate changes in a favorable direction and reaches a certain level.

8. Secure Platform

Bittrex Global employs the most reliable and effective security technologies available. There are many cases of theft, fraud. It is no coincidence that the currency is compared to the Wild West, especially if we compare the 1800s when cowboys rushed to the West Coast of America to earn and start something new in a place that had no rules.
Cryptocurrency is still wild. One can earn and lose money fast. But Bittrex has a substantial security policy thanks to the team’s huge experience in security and development for companies such as Microsoft, Amazon, Qualys, and Blackberry.
The system employs an elastic, multi-stage holding strategy to ensure that the majority of funds are kept in cold storage for extra safety.
Bittrex Global also enables the two-factor authentication for all users and provides a host of additional security features to provide multiple layers of protection.

The new IP address must be confirmed from the device that you are using to access Bittrex Global. This means that you must follow the CLICK HERE TO LOGIN link in an email on the device that you want to use to access your account.
https://preview.redd.it/tq9eje795zh51.jpg?width=607&format=pjpg&auto=webp&s=160b2ebfd1b9e0a287d4d2b99017dd45518ef2f7
To ensure even more security, Bittrex Global supports whitelisting of IP addresses and Crypto addresses. These two features can help protect the account in the event of credentials or API key loss.

How to Add IP Address to Whitelist

By setting one or more whitelisted addresses, you are telling Bittrex Global to only authorize trades or withdrawals from those IPs. This concerns both the global.bittrex.com web interface and API-based trades or withdrawals. To do this, click IP Whitelist in Site Settings.
https://preview.redd.it/m2klahja5zh51.jpg?width=971&format=pjpg&auto=webp&s=7cfb941ecb5284973baed1a2b0301459e36a0ab6

How to Add Crypto Address to Whitelist

By setting a withdrawal address, you are telling Bittrex Global to authorize withdrawals only to that address.
This concerns both the global.bittrex.com web interface and API based withdrawals.
Note that when opting into this feature, you need to specify a withdrawal address would like to withdraw funds from for every currency. To do this, click Withdrawal Whitelist in the Site Settings section. The example below shows a BTC address.
https://preview.redd.it/yrror8zd5zh51.jpg?width=974&format=pjpg&auto=webp&s=179dd7da9f6e59d3fca628cbfcd2c3962562f911

Depositing USD on Bittrex

Crypto assets ensure that replenishment and all exchange transactions are kept through digital currency. Therefore, in case you need to withdraw cash, you must first convert it into Bitcoin (BTC).
At the same time, there may be some other ways to refill the balance with US dollars, which entails filling a particular form for depositing in dollars—Fiat USD trading Request.
To gain a digital currency on the exchange you need to visit your private account and find the Wallets section where all the wallets are shown.
The platform creates a crypto address to which we transfer funds. Money can be credited to the exchange within two days, with the time required depending on the currency and mode of payment (e.g. bank transfer, credit or debit card, and so on).
Therefore, after the transfer, the funds are credited to the exchange's internal wallet.
In order to include a user account for depositing and withdrawing funds in dollars, Bittrex must add the user’s bank account to the white list. Therefore, to replenish the balance with fiat money, you must fill a special form.
  1. Obtain approval for Fiat (USD) Trading, Deposits, and Withdrawals.
To do this, fill out and submit the form: https://bittrexglobal.zendesk.com/hc/en-us/requests/new?ticket_form_id=360000352300
https://preview.redd.it/jwcp2jguied51.jpg?width=861&format=pjpg&auto=webp&s=9ef519cbcf579cc3567e53b55af29fa154e342e3
Keep in mind that wire transfers can only be received from bank accounts approved through the fiat trading application.
2) Make sure your bank account has been whitelisted.
Sign in to your Bittrex Global account. Go to the Holdings Tab. Type “US Dollar” in the search bar. Click the Withdraw button beneath Actions. All available whitelisted (approved) bank accounts will be shown.
https://preview.redd.it/ldwmvt3wied51.jpg?width=974&format=pjpg&auto=webp&s=71d3da503e050f5b4d231184ea82f65fd477b671
3) Generate your USD deposit code.
To get a USD deposit code, click the Holdings tab. Type “US dollar” in the search bar, click Deposit beneath Actions. Your USD deposit code will appear at the bottom of your Wire Transfer Instructions. Copy this code and input it in the memo/notes subject of the wire transfer form to your financial institution.
https://preview.redd.it/pf7sowxxied51.jpg?width=974&format=pjpg&auto=webp&s=c99b3c10a1921254e8247c77a04f529bc60e290b
Use your USD deposit code every time making wire transfers. Wire transfers cannot be processed without a correct USD deposit code.
4) Best practice: Use the wire transfer information provided in your USD wallet when asking your bank for assistance.
Bittrex recommends that users resort to a local bank branch when sending wire transfers for the first time.
To show wire info, enter the "US dollar” in the search bar at the bottom of the Holdings page. Then click Deposit beneath Actions. You will see all the wire information. Use the deposit data to fill out a wire transfer form correctly. In case the info does not appear or if you have questions, please contact Bittrex Global support.
Make sure the wire transfer is not sent as an ACH transfer. ACH transfers aren't permitted so they will be banned.
Be aware: Wire deposits (wires sent to Bittrex Global) CANNOT be initiated on the Bittrex Global webpage. Only withdrawal wires can be initiated on the webpage. All wire transfers must be processed from the bank account number that was provided to Bittrex Global, in your fiat money transfer application.
5) Wait for the amount to be credited to your Bittrex Account.
All USD deposits are credited the same or next-business-day once settled in Bittrex's bank account.
Wires take 5-10 days to settle.
More delays will occur if the wire data does not fit the whitelist.
Wire transfer charges: Bittrex exchange does not take any wire transfer fee. Please ask your bank about the commission it charges for sending or getting a wire transfer. International banks usually involve mediators so check the commission the intermediary charges for their services.

Bittrex Review: One of the First Crypto Exchanges Part 1

Bittrex Review: One of the First Crypto Exchanges Part 1

By Rinat Arslanov, CEO at Revain
Despite the fact that digital asset trading is a relatively new phenomenon, among cryptocurrency exchanges Bittrex is considered a time-tested trading platform that can guarantee a high level of security and reliable service. Today, in this all-encompassing review, we will study how Bittrex Global, one of the most popular and secure crypto exchanges, operates.

Review Contents:

  • Bittrex History and Founders
  • What Bittrex Is and How It Works

1. Bittrex History and Founders

Bittrex Global is currently the oldest holding company concerned professionally with digital assets, as well as having access to major US and European financial markets. It grew out of a small cryptocurrency exchange that started with mining bitcoins for $30 back in 2011. Now the holding, whose headquarters is located in the Principality of Liechtenstein, provides a trading infrastructure to its users, enjoying a reputation of one of the safest exchanges in the world.
Bittrex Global has managed to gain such customer trust and loyalty through the continuous development and implementation of the most advanced technologies that have proven their worth by continuous and reliable operation throughout the 7 years of their existence. The company always ensures fair opportunities for investing in and trading digital assets for all clients, regardless of trading experience.

To this day, since January 2018, Bitcoin has not been able to rise higher than that time.
https://preview.redd.it/nqcifr3hodc51.jpg?width=974&format=pjpg&auto=webp&s=dfb81067c58d42dcf423b303b2e108d04c5121c9
The future Bittrex team really wanted a way to acquire Bitcoins again. Mining was going to prove untenable, so they brainstormed and started the first crypto-based business—GiftcardBTC.
At that time, Bittrex had a simple idea of earning through selling gifts and calling cards for Bitcoin. It was so easy to earn cryptocurrency and then convert it into fiat US dollars, and that endeavor made it possible to offset the costs. Then, the founders of the future cryptocurrency platform designed a Bitcoin miner that started to earn money continuously, but this was not the limit of their dreams.
Less than a year later, the first cryptocurrencies—Bitcoin and its fork Litecoin—got up in price many times and then the creators of Bittrex added Litecoin to their package. Using Coinpayments.net infrastructure for processing payments, they ran into problems, since there were still practically no abilities to convert or withdraw cryptocurrencies into fiat currencies. The founders began to look for convenient automatic ways to do this but at that time exchanges could not provide such services.
At that time, Bill Shihara and Richie Lai regularly traveled to Las Vegas and in late 2013, during one of such trips, they were discussing the problems they faced for many hours, trying to find a solution and considering various options. In the end, they decided to start software development in the west. Now this decision is considered the birthday of the Bittrex trading crypto platform.
They decided to invite a professional from Microsoft, Rami Kawach, to discuss their idea. After some time, they had an ambitious plan to develop and launch a platform for crypto exchange in less than two months. The plan was accompanied by a gentleman's dispute among Rami, Richie, and Bill over a bottle of 25-year-old whiskey, which concerned the timing of the plan.
The formed team began to work actively on a project to which they devoted all their free time and worked day and night. In mid-February 2014, they launched the Bittrex website, and on the last day of February, they made it accessible for the general public. As a result, Richie and Rami won over whiskey against Bill.

It was then when a large partnership began; later, the alliance ensured the joint company’s future success. They formulated several postulates that became the cornerstone of their business:
  1. We ourselves will never trade cryptocurrencies on our exchange. Too many shadows occurred in too many places, and we will not trade against our clients.
  2. We will always maintain honesty on our exchange. No one gets special information. No one gets special prices. Transparency is paramount.
  3. We will never sacrifice long-term gain for short-term gain. We have been together for a long time.

2. What Bittrex Is and How It Works

Bittrex is a multi-currency trading platform where you can exchange, buy, or sell cryptocurrency and fiat money. The exchange is available in all facets: you have great opportunities in making foreign exchange transactions, both with digital assets and with ordinary money.
Not everyone understands what fiat currencies are, but in fact, these are the good old usual paper cash and non-cash money that are issued by the central banks of various states. Fiat money mainly differs from cryptocurrencies in that it is regulated by governments, which can influence their output and exchange rate.
On the Bittrex crypto exchange, you will find more than a quarter of thousand of various types of cryptocurrencies and 364 currency pairs. A currency pair is a pair of currencies that can be exchanged one for another at a certain rate. The most common currencies can be exchanged for hundreds and thousands of other currencies, both digital and fiat. Cryptocurrencies such as Bitcoin Litecoin or Ether have the largest number of pairs available for exchange.
Appearance cements the first impression, and the user interface is key in any digital. In Bittrex, the interface is intuitive even for those taking their first steps in trading. Not only does it look sleek but it’s also very easy-to-use. You only see what you need on the trading screen.
Here you can see structured information about trading pairs, history of changes in exchange rates, and wallets. The website will guide you on how to make a deposit, how to work with orders, what happens to your money, and how to withdraw it.
All work with such a platform begins with the opening of an exchange account. You can find everything you need to configure a wallet in Settings.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. 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)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
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.

"Swap" is Poised for Take-off


https://preview.redd.it/mnxeb74hk4j51.jpg?width=990&format=pjpg&auto=webp&s=32d152a7495971c10e1af12185abe5e77b61fd14

How popular is DeFi?
Link, known as the leader of the oracle machine, has increased by 305.19% for the past three months, with an investment return of 17,052%, climbing to the fifth spot in the cryptocurrency ranking list by market value in the short term;
Since its issuance, YFI, which has soared 350 times all the way, has attracted 630 million US dollars of investment in 5 days, and was even dubbed the next Bitcoin in this circle;
From Comp for lending, KNC and BAL, governance tokens for decentralized exchanges, to SNX which is a stable currency payment network, various governance tokens of the DeFi ecosystem have emerged in an endless stream, stirring the blood in the market.
Such a boom is not only reflected in the currency price, but also pushes the brand new DEX based on the AMM (automated market making) model an overnight hit. UniSwap, known as the next-generation casino, has surpassed the world's first-tier centralized exchanges such as Binance, OKex, and Huobi in user activity, daily trading volume, and daily turnover.
With the rapid rise of UniSwap, the DEX threat theory has once again triggered heated discussions among the media and communities in the blockchain industry.
DEX on the Rise
The success of UniSwap is by no means something accidental. As early as 2018 when centralized exchanges suffered the hacker theft one after another, Vitalik Buterin, founder of Ethereum, predicted that the future lay in decentralized exchanges and that Ethereum, by developing a "better" decentralized platform, could empower the cryptocurrency community to regain the dominance from the centralized cryptocurrency exchange.
To realize the decentralized concept of returning to users their asset ownership, geeks in the blockchain industry have made many attempts.
Kyber Network, Bancor, Balancer, 0X, Curvefi, etc. are all DEXs based on Ethereum blocks. For a long time, affected by the performance of Ethereum and cross-chain issues, these DEXs were once stagnant.
With the lessons learned from Ethereum DEX, newcomers to the DEX have focused on high performance, high TPS, and rich assets as the ultimate goal for product development.
Amid the DEX threat theory, major exchanges have deployed their own public chain DEX products in a response to their respective development strategies: Binance launched Binance DEX on its Binance Chain, and Bittrex Exchange unveiled Ethfinex on the Ethereum and EOSfinex on the EOS blockchain, two platforms where users can exchange for fiat currencies; last year, CoinEx officially launched CoinEx Chain, a public chain dedicated to decentralized transactions, followed by CoinEx DEX.
Since the birth of the DEX in the blockchain world, this field has never run out of competition.
By independent development or other’s advantage?
From 2017 when it was established to 2019 as it stabilized, DEX has witnessed its annual trading volume skyrocketing from less than US$5 million to over US$2.5 billion. As DeFi gains fame and grows rapidly, DEX has grown into the most popular source of money, attracting a flood of speculators. In the past month, the trading volume of the global cryptocurrency market DEX has exceeded US$ 4 billion, more than twice the figure across 2019.
In the past two years, despite the increasingly in-depth exploration in the DEX, the cross-chain issue remains a stumbling block in its development path. DEX will not outperform CEX in the trading experience until a cross-chain solution is worked out.
The concept of DeFi went viral in 2019. With the continuous improvement of the DeFi ecosystem, the current Ethereum blockchain has developed into a complete decentralized financial system, covering mortgage lending, interest from deposit, leveraged trading, token exchange, identity authentication, and other infrastructure essential to traditional financial systems.
In addition to the mouth-watering profit, the DeFi ecosystem has also brought along explosive growth in both the type and quantity of digital assets, making DEX a market favorite. Compared with the DEX dedicated to public chains, the Ethereum-based DEX has been equipped with more possible functions and thus become more attractive thanks to the comprehensive supplementary infrastructure on Ethereum.
This also presents DEX pioneers with new opportunities. Dubbed “Swap’s summer”, the summer of 2020 has seen a market rush in Swap development after UniSwap became a hit.
Miniswap, Justswap, and btswap are no more innovative than UniSwap according to their product structures and white papers.
By comparison, OneSwap has injected unique essence into its product design and governance model based on UniSwap's automated market making.
Upgraded UniSwap
OneSwap, which has a double mining model + order book, has received an investment of tens of millions from CoinEx even before the product is launched. It is known that OneSwap is jointly developed by a group of technology geeks who have engaged in the cryptocurrency community for many years. The project was initiated by a member of the team in an attempt to upgrade UniSwap after he experienced the convenient AMM enabled by UniSwap.
Without limit orders, users have to trade in the price set by the platform, which, however, compromised their experience. In addition, the lack of liquidity mining and transaction mining rewards cannot reduce the losses of liquidity providers caused by unilateral market conditions.
"DEX still has much room for perfection, and could even surpass CEX in trading experience"
The OneSwap development team always believes that UniSwap still has a long way to go before it becomes the strongest DEX in the DeFi ecosystem. They have endeavored to, relying on their abundant experience in exchange product development and digital currency trading, create the most powerful DEX product in the DeFi ecosystem based on smart contracts.
OneSwap is called the “upgraded UniSwap” in the community. By the combination of the Constant Product Market Maker (CPMM) model in the Uniswap project and the on-chain order book, it reduces restrictions on users’ trading, and, through its OneSwap Wallet, improves user interaction methods and further enhances their experience in trading and product usage.
OneSwap boasts one-click token issuance and listing essential to DEX. Unlike the listing review mechanism on Binance DEX, the setting of OneSwap is more consistent with the concept of decentralization. Anyone can put his or her good projects and ideas, if any, into practice through OneSwap without permission.
In terms of product design, OneSwap will add to its function menu the Candlestick chart, order form, and depth chart according to user habits, apart from limit orders. These functions will offer OneSwap users an experience as smooth, easy-to-use, and convenient as in the CEX.
A new source of money? A two-pronged platform with transaction mining + liquidity mining
To support on-chain governance, OneSwap will issue a ERC20 governance token called ONES. The total number of ONES remains constant at 100 million, 50% of which will be used as community funds to support the construction of the OneSwap ecosystem and 50% will be owned by the OneSwap team. Community funds can be applied for through on-chain governance. 5% of the part held by the team will be unlocked initially, and the rest will be unlocked at a rate of 5% every six months until all is unlocked after four and a half years.
After the OneSwap product was launched, the OneSwap team will take part of the initially unlocked tokens as airdrop rewards for the open beta. Then OneSwap will officially start liquidity mining and transaction mining, and the governance token ONES will also be simultaneously launched on centralized trading platforms across the world. The first round of mining activities will last for one month, and mining rewards are yet to be made public.
Liquidity mining is a popular way of obtaining governance tokens in the DeFi ecosystem. Well-known DeFi projects including COMP, Cure, and Banner have all enabled liquid mining.
Transaction mining could date back to 2018 when Fcoin grew popular.
The transaction mining model initiated by Fcoin in 2018 once set off a bull market that year, pushing many investors into financial freedom in the rush of transaction mining. In addition, transaction mining based on the DeFi ecosystem is still a blue ocean, which is not common in the current market. The success of OneSwap's double mining model, if possible, would surely start a craze in the cryptocurrency market.
The OneSwap team has not yet announced specific mining rules, but disclosed that it has developed the smart contract code. To ensure the product security, OneSwap will invite three well-known security agencies in the blockchain industry to audit the code and announce the auditing results in early September at the soonest.
Conclusion
DeFi did not rise to fame without reason in 2020. Such overnight popularity is an inevitable result of Ethereum's efforts to build a decentralized consensus mechanism and improve infrastructure in the past few years. Ethereum has almost become the only public chain in the DeFi circle and the only construction base for well-known DEX. If OneSwap succeeds, it means a huge breakthrough for both DeFi and Ethereum, and decentralization in its true sense is around the corner.
