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 summaryDragonchain 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 PoCIn The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactionsOn 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
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:
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.
How it works & scales
Architectural ScalingDragonchain’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 ScalingAn 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 DeploymentDragonchain 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 ScalingDragonchain’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.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table
How to run itBuilding 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...
ArchitectureDragonchain 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.
APIs (on chain & off)
Known issues or tradeoffs
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to considerDragonchain’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.
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 transactionsDragonchain 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.
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.
Users should be able to view their balances & transactions via a blockchain explorer-style interfaceFrom 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 & simpleWithdrawing 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
Documentation should be clear and completeFor 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 Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
TIMECommunity 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 DenDragonchain 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 elseUsers 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 elseThrough 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 offlineIf 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 availableTo 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 pointsSee above
Compatibility with HSMs & hardware walletsFor the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directlyThis 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 scalableThis is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferredDragonchain is fully open source (see section on Disney release after conclusion).
ConclusionWhether 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 SourceThe 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.
Open SourceIn 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:
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.

We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
SolutionsSyscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Syscoin + Matic IntegrationMatic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Proving Performance & Cost SavingsOur POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014
The demonstration was executed using this tool. The results can be seen in the following blocks:
It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.
Cost SavingsTotal cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

DocumentationSyscoin Bridge & How it Works (description and process flow)
Superblock Validation Battles
HOWTO: Provision the Bridge for your ERC-20
HOWTO: Setup an Agent
Developer & User Diligence
Trade-offThe Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
CostEthereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Z-DAGZero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).
APISyscoin-js provides tooling for all Syscoin Core RPCs including interactivity with Z-DAG.
DocumentationZ-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana
Trade-offZ-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.
Syscoin SpecsSyscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
WalletsWeb3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.

We recently had the opportunity to interview the VP of ViaBTC Group, Eddie Jiang. ViaBTC Group owns popular crypto exchange CoinEx and ViaBTC Pool. In this interview Eddie discusses being the first exchange to use BCH as the base currency, ViaBTC Pool and integrating with CoinEx, new features and ambassador program, and competing with other exchanges like Binance and Huobi. Please enjoy the interview below.
How come you decided to open up CoinEx to other cryptos other than just BCH?
Eddie Jiang: CoinEx is the world’s first exchange to implement Bitcoin Cash as a base currency. At that time, it was evident that there was a demand for BCH trading markets, and we are the first to explore this opportunity. It also shows our determination to support the BCH’s development.
As CoinEx is developing, our goal becomes bigger and we are aiming at the global market. We need to constantly improve our product diversification to meet the different needs of more users, so we open up to other cryptos. In the past six months, we have listed more than 50 new tokens. Up to now, we have listed 129 cryptos and 313 markets. Besides, in addition to spot trading, CoinEx also supports perpetual contract and other derivatives trading.
How does CoinEx integrate with the ViaBTC Pool?
Eddie Jiang: ViaBTC Group announced a strategic upgrade, which included a new organizational structure, product innovations and service improvements, on 30 May.
As part of the change, the Group has established three dedicated business units (BU): the financial services BU, consisting of ViaBTC mining pool and CoinEx exchange; the infrastructure services BU, including ViaWallet and Blockchain Explorer; and the ecological development BU, focusing on the research and development of public chain technology and the construction of the ecology.
After halving, the combination of mining and finance will become closer and closer. Investing in mining machines is like buying a Bitcoin option. Miners need more flexible financial products to maintain and increase the value of assets, or hedging services. Based on this judgment, the operations of ViaBTC mining pool and CoinEx exchange will be integrated in the future to realize the financial empowerment of the mining pool to meet the diverse financial needs of miners.
Features of this integrated product upgrade can be summarized as: “ The mining pool is the wallet, and the wallet is the transaction.” ViaBTC is the world first mining pool that has a wallet embedded in the mining pool account. Users do not need to transfer the mined coins, and can realize the function of coin exchange within the wallet. For example, they can directly convert the mined coins into USDT to pay electricity bill. What’s more, users can store, deposit and withdraw their revenue, and transfer assets to CoinEx at any time without charge, as well as complete other operations on the exchange, such as purchasing wealth management products for asset preservation and appreciation. In addition, we also provide hedging services. All of the above functions can be completed in one stop in the mining pool, without the need to transfer assets between different platforms.
The exchange empowers the mining pool, and the mining pool will further bring more traffic and resources to the exchange. The two complement each other and development coordinately.
CoinEx has recently added many new features. Can you talk about what new updates were made to the platform and why you made them?
Eddie Jiang: We have always attached great importance to the development of overseas markets since our establishment, and one of our major goals this year is to cover at least 10 different languages speaking markets.
To realize this and to meet the needs of more users worldwide, CoinEx has been continuously optimizing and upgrading its operating strategies, products and services. Our product diversifications are constantly improving. As I said before, we have launched leverage trading, perpetual contract trading, and wealth management products in addition to just spot trading. However, we don’t ignore the importance of spot trading. More mainstream, popular, and high-quality tokens have been listed, and up to now, there are 129 tokens and 313 trading pairs on CoinEx.
During the epidemic, we have never slowed down our development. Lacking of the OTC service has always been a shortage for CoinEx. In March, we partner with Simplex to integrate the first fiat onramp to our platform. People now can buy crypto with their credit cards, which lowers the threshold for more people to enter the crypto world. Moreover, we announced global strategic partnership with Matrixport to provide people with large amount of fiat to crypto needs the OTC service. These newly launched services also help to attract more users.
At the same time, CoinEx has been launched in Arabic, Italian, English, Japanese, Russian, Korean and other 16 languages. Earlier we also carried out product upgrades, making the UI and function sections clearer.
In terms of operations, we launched an upgraded CoinEx Ambassador program in March. To best utilize each ambassador’s personal strengths, there are four categories of CoinEx Ambassador with different responsibilities, namely Referral Ambassador, Marketing Ambassador, Operation Ambassador, and Business Ambassador, which will expand our brand’s exposure and help CoinEx grow into a more international exchange platform.
From March until now CoinEx has seen a 100% increase in user registrations. Why is that and are you able to see where they are coming from?
Eddie Jiang: Because of the efforts mentioned above, in 2020, we’ve seen an exponential increase in activity in just the past few months alone. In this year alone, CoinEx’s daily registered users increased by 100%. These new users mainly come from markets such as the Middle East, Asia Pacific, and more.
Interestingly, we saw an uptick in traffic from the Middle East in March. User growth in Southeast Asia also picked up significantly, newly registered users increased by 133.6% in April.
With Binance, BitMex, Huobi, Bybit, and Deribit, controlling most of the crypto futures and options markets, where do you see CoinEx fitting in? How do you plan to capture market share from these large exchanges?
Eddie Jiang: We won’t compete with others. We focus on ourselves to improve products and our goal is to be better than yesterday.
Our pace is solid and steady, instead of focusing on temporary heat and flow. We have always attached great importance of spot trading, and we are committed to be responsible for users’ investment. We have set up CoinEx Institution, which is dedicated on project research. A listing committee consist of core team members review and vote on projects recommended by the CoinEx Institution. In this way, fraud projects are avoided as much as possible.
Besides, we will focus on niche areas with great potential. For example, Southeast Asia and the Middle East. CoinEx can serve users in those countries well by providing a platform with rich cryptos to trade, and will pay more efforts on refined operations in different countries.
Moreover, CoinEx has a very complete ecosystem. Financial services, infrastructure, and ecological development, the three business units complement each other. The infrastructure BU is our cornerstone and is positioned as a defensive product; the financial service BU is a cash cow and is positioned as an aggressive product; the ecological development BU focuses on the public chain ecology and is the future infrastructure.
What is the geographical breakdown of the CoinEx userbase?
Eddie Jiang: The current proportion of CoinEx’s overseas users has reached 80% of the total registered users, and mainly in Australia, Southeast Asia, North America, Middle East and South Korea.
Do you have plans to focus on any certain jurisdictions? How will you do that?
Eddie Jiang: When we evaluate regions, two things matter: policy and potential.
Whether an exchange’s business expansion in a region is smooth or not largely depends on the region’s policies. If the region is not very friendly towards cryptocurrency or has repeated attitudes, there will be more difficulties and the cost will be much higher.
For a region’s development potential, we need to think about the demand and market development status. South Korea, Southeast Asia, the Middle East and other regions are all areas with good potential for cryptocurrency development. Compared with Europe and America, policy risks in these countries are lower, and the supervision mechanism is relatively complete. The public has a high degree of awareness of cryptocurrencies. Besides, some regions or countries have inflation problems due to political and economic reasons.
CoinEx will continue to focus on the Middle East and South Asia, which are relatively niche. India has just lifted ban on cryptocurrency trading this year, and there are many cryptocurrency investors in Indian. CoinEx can serve them well by providing a platform with rich cryptos to trade. More people in the Middle East are interested cryptos, especially in countries that are subject to economic sanctions or high inflation. For those people, cryptocurrencies are one of the best choices for asset preservation.
Since the CoinEx Ambassador program launched in March, it has been almost three months. We are conducting the second round of ambassador recruitment. This time, we will use the power of ambassadors to expand our recruitment coverage and strive to attract more crypto enthusiasts from all over the world to grow together with CoinEx. Moreover, we will launch the National Expansion plan and leverage on the CoinEx and ViaBTC mining pool resources, to further explore the Russian market. At the market level, we will make more PR efforts in local markets, and start refined operations.
What is CoinEx Chain and CoinEx DEX?
Eddie Jiang: CoinEx Chain is a public chain built on the Tendermint consensus protocol and the Cosmos SDK. It consists of three dedicated public chains parallel to each other. Among these three chains, CoinEx DEX meets the most basic needs of DeFi for token issuance, transfer, and transactions. The Smart Chain is designed to meet the needs of complex financial scenarios and delivers programmable cash. The Privacy Chain facilitates privacy and security.
On November 11, 2019, we took the lead in launching the Mainnet of CoinEx DEX. CoinEx DEX is the world’s first public chain dedicated to decentralized transactions. Users can easily manage their digital assets on it.
CoinEx DEX can fully satisfy the following conditions: users have private keys at their own disposal; transfers and transactions are all completed on-chain, which is 200% transparent and checkable; the issuance, transfer, and transaction of tokens do not require review or permission; the community governance and operation is decentralized, similar to EOS, and validators are introduced to the community ecosystem construction and governance. There are currently 41 validators.
It also has extreme performance. TPS reaches as high as 10,000 and transactions are confirmed within seconds. The transaction fee, 0.0001 US dollars for each transaction, is negligible.
Third, it’s simple and easy to use. The new operation interface design helps beginners get started quickly; with the one-click token issuing module, users only need to fill in a few items to issue tokens; the built-in automated market-making module guarantees liquidity.
How will CoinEx DEX improve the decentralized exchange space that has been unable to gain much adoption?
Eddie Jiang: There are many challenges and difficulties facing centralized exchanges. The first difficulty is security. Security is a huge concern for CEXs. Over the last 10 years, hackers have stolen more than $1.5 billion from centralized exchanges. In fact, research groups estimate that hackers stole somewhere between $950 Million and $1 Billion from centralized exchanges in 2018 alone. There were also incidents of coin thefts in other exchanges in 2019. Many exchanges, such as Mt. Gox, Youbit, were forced to file for bankruptcy and shut down as a result of hacks.
The second is high management costs. Centralized exchanges need to list a large number of cryptocurrencies and each of them have different trading pairs. That entails huge efforts in development and maintenance and, thus, high management costs.
The last is global policies. Cryptocurrency is faced with different regulatory policies in different countries. Every time a centralized exchange enters a country, it needs to adapt itself to local regulatory policies for compliance. This is a holdback for the exchange’s rapid market expansion globally. Such adaptation will also bring a huge learning cost for the exchange team.
Obviously, these problems can be well solved by DEX. CoinEx DEX is a true DEX with full open source and full community governance, as well as without depending on official nodes, websites, wallets, etc. On DEX, users are able to in charge of their own private keys and assets all by themselves. Their assets are more safe and secure. Transfers and transactions are all completed on-chain, which is 200% transparent and checkable; and the issuance, transfer, and transaction of tokens do not require review or permission. What’s more, CoinEx DEX provides a great and convenient user experience.
How will CoinEx Chain and DEX help the crypto industry as a whole?
Eddie Jiang: The public chain is the cornerstone of the blockchain industry. CoinEx Chain has the parallelism of multiple dedicated public chains, each of which performs its own functions, by cross-chaining for both high performance and flexibility.
CoinEx Chain is committed to building the next generation of blockchain financial infrastructure. It is a more complete ecosystem built around the DEX public chain. The DEX public chain is a dedicated public chain developed specifically for token issuance and trading and the biggest improvement on trading speed, so it only supports the necessary functions, not smart contracts.
But smart contracts are the foundation for building more complex financial applications. Outside the DEX public chain, CoinEx Chain also includes a Smart Chain that supports smart contracts.
Moreover, as privacy issues on the current blockchain have been criticized, it is one of the core tasks of CoinEx Chain to safeguard users’ privacy. Similar to the Smart Chain, the Privacy Chain specifically supports transaction privacy protection. With cross-chain circulation, it can improve the privacy characteristic of the entire CoinEx Chain ecosystem.
Nowadays, 1.7 million people in the world have no bank accounts; however, among them, two thirds are smartphone users with huge demands for financial services. The public chain will empower DeFi applications’ development and popularization, not only help more companies to seize the huge market opportunity, but also to bring lasting transformations and improvements in people’s lives.
With so many crypto exchanges, what is the future outlook of CoinEx when it comes to the crypto exchange space?
Eddie Jiang: It has been nearly 3 years since CoinEx has been launched, but it’s quite young for an entrepreneurial team. We have seen too many projects’ failures due to governance issues. CoinEx has a very elite team with high technical and management capabilities. In terms of business, CoinEx has gradually developed with diversified business and a complete ecosystem. It’s clear that the market will still grow very fast in the future, and the market size is still very large. We will continue to improve our products, put more efforts in marketing and operations, as well as look for more high-quality projects, to increase the number of users and transactions on the platform. Lay a solid foundation, and I’m sure the time will come for us to shine.
What updates is the CoinEx team most excited for?
Eddie Jiang: We are very excited about the National Expansion Plan which will be launched later this year. It is an important part in CoinEx’s globalization strategy. We will actively explore some new markets while consolidate the original ones. CoinEx will set aside 10 million US dollars to set up a “Pioneer Fund” to support this plan. This fund will be used to support local cryptocurrency projects and promote the development of the local cryptocurrency communities through investment or cooperation. Our goal this year is to invest in projects and communities that are conducive to expanding the CoinEx ecosystem in countries with high development potential.

OutlookThe development of CoinEx Chain contributes to the future development of CoinEx’s centralized and decentralized exchanges; the concept of trichain operation simplifies the functions of each chain, improving their performance. At present, there are few exchanges working on the public chain, and no fierce competition has occurred.
ConclusionConsidering the status and development prospects of the project, TokenInsight gives CoinEx a rating of BB with a stable outlook.
1. Multidimensional evaluation
2. Project analysisCoinEx (CoinEx Technology Limited) was established in December 2017 and is headquartered in Hong Kong, China. It is a sub-brand of the ViaBTC mining pool. At present, CoinEx’s business scope includes CoinEx exchange, CoinEx public chain, and CoinEx decentralized exchange. The current development focus of the CoinEx platform are public chain and exchange. The main purpose of the public chain is to build a decentralized exchange (DEX) infrastructure and an ecosystem around DEX.

2.1 Introduction“ CoinEx Chain uses the parallel operation of three chains which are DEX, Smart, and Privacy, as well as cross-chain technologies to create a rich decentralized exchange ecosystem and blockchain financial infrastructure.
The core of CoinEx’s early business was the exchange, consisted of two major categories which were spot and derivatives trading. Currently, there are 123 trading currencies online, covering 302 trading pairs. On June 28, 2019, CoinEx released the CoinEx Chain public chain white paper, aiming to build a decentralized trading system (CoinEx DEX) with community-based operations and transparent transaction rules, and providing user-controlled asset trading scenario by the highest technical standards in the industry; CoinEx Chain has become another development focus of CoinEx. CoinEx Token (CET), which was originally a native token of the CoinEx exchange, will also be developed mainly as a built-in token of the public chain.
CoinEx Chain is a public chain based on the Tendermint consensus protocol and Cosmos SDK, and it uses POS mechanism. CoinEx Chain plans to support 42 nodes when the project starts, and any entity in the ecosystem can participate in the validator’s campaign by staking CET. CoinEx Chain will use the new block reward and the transaction fee contained in the block as the reward for running the node.
CoinEx Chain has developed three public chains with different positioning and different functions in order to meet the needs of blockchain transactions for transaction performance, smart contracts, and privacy protection at the same time. They operate in parallel and collaborate with each other through cross-chain technology. At present, the block time of the public chain is between 2–3 seconds. According to the observation of TokenInsight, the block time is stable, but the number of transactions through the CoinEx public chain is still low at present, the number of transactions in 24 hours is about 30,000; The TPS on public chain disclosed by CoinEx can reach up to 1500 per second.
CoinEx Chain uses a trichain parallel model to build a more vibrant ecosystem around DEX. The three chains are DEX public chain, Smart public chain, and Privacy public chain, respectively responsible for decentralized transactions, smart contracts, and on-chain privacy protection.
CETs that need to participate in complex financial contracts can be transferred to the Smart public chain through the DEX public chain, then moved back to the DEX public chain after that. CET tokens that need to participate in token confusion can also be carried out through the privacy transaction of the Privacy public chain, and can eventually be returned to the DEX public chain. The three public chains are responsible for their respective duties, and they are interconnected through the cross-chain technology through the relay mechanism. In addition to ensuring their respective transaction processing speed and functional attributes, they can also jointly provide richer and safer functions, and synergistically constitute the CoinEx decentralized public chain ecosystem.
In addition, CoinEx Chain also supports any participant to issue new tokens on the chain and create new trading pairs for the issued tokens. CoinEx Chain guarantees the circulation of new tokens by establishing a trading pair between the new token and CET.
2.2 Component architecture“ Tendermint Core and Cosmos SDK have improved the performance and operation capability of the blockchain. The SDK packaging reduces the consideration of non-related logic, hence reducing the development complexity.
CoinEx Chain is based on Tendermint Core and Cosmos SDK, both of which have brought a big boost to the development of CoinEx public chain performance. Cosmos-SDK will implement the application logic of the blockchain. Together with the Tendermint consensus engine, it implements the three-layer architecture of the CoinEx public chain: the application layer, the consensus layer, and the network layer.
Tendermint is based on the state machine replication technology and is suitable for blockchain ledger storage. It is a list of transactions making consensus with Byzantine fault tolerance, the transactions are executed in the same order, and eventually the same state is obtained. Tendermint can be used to build various distributed applications.
Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains.
Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains. The blockchain development framework Cosmos SDK implements general functions such as account management, community governance, and staking in a modular form. Therefore, using the Cosmos SDK to build a public chain can simplify development procedures and facilitate operation. Tendermint is a fixed protocol in a partially synchronized environment, which can achieve throughput within a delay range of the network and each process itself. The CoinEx public chain is developed based on both, improving the performance and operability of the blockchain. The SDK packaging further reduces considerations of non-related logic and reduces the complexity of developers creating. The two components of Tendermint and Cosmos SDK are connected and interacted through the Application Blockchain Interface.

2.3 Project public chain planningThe development plan of the CoinEx public chain is to create a series of public chains with specific application directions, including:
2.4 Operation analysis“ The CoinEx platform publishes monthly ecosystem reports with high transparency; but the monthly reports are limited to contents about transactions and development, and lack progress in ecosystem and community construction, making them relatively simple.
2.4.1 Disclosure of ecosystem information
Operational risks have a direct impact on platform users. Whether platform operations are smooth and whether there is transparency are issues that platform users care about.
The CoinEx platform was established in 2017 and has around 3 years of development. It is also one of the platforms that has been developing for a long time in the exchange industry. It has obtained a digital currency trading license issued by the Estonian Financial Intelligence Unit (FIU), and the platform’s compliance is guaranteed to some degree.
The actual operation of the CoinEx platform will be displayed in the form of ecosystem monthly reports. The monthly report contains various types of content such as online currencies, new activities, plans for the next month, and ecosystem dynamics. It involves multiple business dimensions including the CoinEx exchange, CoinEx Public Chain, and CET token.

CoinEx Chain released its development roadmap for the four quarters of 2020 in January 2020. The roadmap shows that CoinEx Chain will undergo major updates on smart contracts and DEX hard fork upgrades. The project roadmap is basically planned on a monthly basis, with a clear plan and a clear direction of development.

In addition to the development route planned in the roadmap, CoinEx public chain also discloses its goals for next month in its monthly ecological report. The project’s main net was launched online in November 2019. According to TokenInsight’s review of the development of CoinEx public chain from January to April and the disclosure of the project’s ecosystem monthly report, the project’s plan about development of the smart contract Demo in February failed to be completed as planned; the project completed launching of the new version of the blockchain browser and the Asian Atlantis upgrade; the smart contract virtual machine development was planned to be completed in April, but the progress related to supporting cross-chain agreements was not disclosed yet.
Overall, the project’s development route planning is clear, and the project’s development schedule is consistent with the plan, but there are still some discrepancies. Operation and development information is disclosed every month, and information transparency is high.
3. Industry & CompetitorsThe earliest origin of the exchange layout in the public chain field began in early 2018 when Binance released an announcement to start the development of the Binance Public Chain officially. In June of the same year, Huobi announced at its brand upgrade conference that it will combine the technical capabilities of the Huobi technical team and the community developers to develop the Huobi public chain called “Huobi Chain”. In December of the same year, OK Group announced the launch of its self-developed public chain OKchain, dedicating to provide underlying technical support and services for startups stationed in B-Labs.
The successful launch of the public chain brings huge strategic significance to the exchange, which can not only improve the performance of the existing business of the exchange but also achieve further expansion of its influence. As one of the most important blockchain infrastructures, the public chain can benefit the exchanges behind it.
As a platform for developing public chain technology exchanges, CoinEx’s main competitors in the field of public chain development include Binance, Huobi, and OKEx. Although they are all exchange platforms for deploying public chains, the above four are different in terms of specific functions, economic models, and critical points of the public chain.
3.1 Development progress comparisonIn 2019, Binance became the first exchange to launch a public chain among all digital asset exchanges, and its main product is Binance exchange (DEX). In April 2020, Binance announced the launch of a second smart contract chain, using Ethereum’s virtual machine, so that developers can build decentralized applications without affecting the performance and functionality of their original chain.
OKEx launched OKChain’s testnet in February 2020 and completed open source two months later. OKChain is designed as the basis of large-scale blockchain-driven business applications, with the characteristics of source code decentralization, point-to-point, irreversibility, and efficient autonomy.
Huobi released Huobi Chain for the first time in July 2019, the code is open source, and the testnet was released in February 2020. As a “regulator-friendly financial blockchain”, Huobi Chain focuses on providing compliance services for companies and financial institutions.
The CoinEx public chain officially completed the main online launch in November 2019 and completed the new block browser’s launch in March 2020. On April 3, 2020, CoinEx DEX uploaded the underlying code to Github to achieve open source. The CoinEx public chain is more inclined to build a full DEX ecosystem to achieve a one-stop solution for issuing, listing, storing, and trading. The long-term goal is to create a blockchain financial infrastructure.
3.2 Comparison of economic modelsAt present, the exchange is more inclined to use its existing platform currency as the native token of the public chain in the construction of public chain ecology. CoinEx’s CET, Binance’s BNB, and Huobi’s HT all fall into this category. OKEx is the only exchange that issues new tokens for its OKChain, which means OKT is the only ‘inflation token’ in the exchange’s public chain, while CET, HT, and BNB are all deflationary.
3.3 Decentralization of public chainThe initial number of CoinEx public chain verification nodes is 42, which is currently the most decentralized among all exchange public chains, and able to take both efficiency and decentralization into account; OKChain also currently has a relatively high degree of decentralization in the exchange public chain (21 verification nodes), its nodes have a high degree of autonomy; by contrast, Binance still firmly controls the operation of nodes and transactions; In terms of encourages cooperation between regulators and the private financial aspects, Huobi provides a lesser degree of decentralization. Huobi Chain uses a variant of the DPoS consensus algorithm to provide functions such as “supervision nodes”, allowing regulators to become validators.

4. Token EconomyCoinEx Token (CET) is a native token of the CoinEx ecosystem. It was issued in January 2018. Token holders can enjoy some user value-added services within the ecosystem. Currently, it is mainly used as a native token on the CoinEx Chain. As of 11 am on April 23, 2020, the current circulation of CET tokens in the market is 3,215,354,906.31, with a total of 5,842,177,609.53. CET tokens will not be further issued or inflated. Currently, daily repurchase and quarterly destruction are carried out. The repurchase destruction dynamics can now be tracked real-time on the CET repurchase system on the platform.
4.1 Token DistributionThe CET token used to be based on the ERC-20 token developed by Ethereum. Since the CoinEx Chain mainnet was launched in November 2019, some ERC-20 CET tokens have been mapped to the mainnet CET, and the rest of the CET will be mapped before November 10, 2020. CET holders need to deposit ERC-20 CET to the COinEX exchange, and the exchange will conduct the main network mapping.
At present, CET is mainly circulated in the form of mainnet tokens, and only a small portion of ERC-20 CET has not been mapped. The distribution of token holdings currently circulating on the mainnet can be seen in the figure below. At present, the number of tokens held by the top ten holders accounts for about 60.44% of all mainnet CET tokens.
Distribution of CET token holding addresses，Source: Etherscan; TokenInsight
The following figure shows the initial distribution of tokens after the mainnet mapping preset by CoinEx. From the initial distribution map of CET, it shows that, after mapping, a large portion of CET remains concentrated in the hands of the team (31%), and the actual number of CET circulating in the market only accounts for 49% of the total.
The initial distribution of CET token，Source: CoinEx; TokenInsight
After the main net mapping, the 31% of the total CET (1.8 billion) held by the team will be gradually unlocked in the five years from 2020 to 2024, and 360 million CET will be unlocked each year. By 2024, the CET held by the team will be completely unlocked. From the current CET dynamics, the CET share held by some teams has been used for destruction purposes to achieve the purpose of CET austerity. If the frozen 1.8 billion CET held by the team are used for similar purposes, the development of CET and its platform can benefit from it.

4.2 Token economic model4.2.1 Deflation mechanism
Since the CET token went online in January 2018, CoinEx has increased the circulation of CET through airdrops, transaction fee refunds, operation promotion, and team unlocking. As one of the existing platform coins with long development time, the deflation mechanism of CET token has undergone a series of changes with the development of the industry. In 2018, when the concept of coin-based mining prevailed, CET used transaction mining, stake mining, and pending order mining, which were cancelled in October, December and, April respectively of the following year.
The repurchase and destruction model currently used by CET was updated by CoinEx on April 11, 2020. The original CET quarterly repurchase and destruction policy of the platform will be adjusted to daily repurchase and quarterly destruction. After the implementation of the daily repurchase policy, CoinEx will take out 50% of the daily fee income for CET repurchase in the secondary market and implement quarterly destruction until the total remaining circulation is 3 billion (currently about 5.8 billion).
At the same time that CoinEx updated the repurchase and destruction plan on April 11, the platform also launched a page dedicated to displaying CET repurchase information, so that users can clearly understand the progress of CET repurchase and destruction.
As of April 23, 2020, the platform has destroyed 4,157,822,390.46 CET tokens, accounting for 41.6% of the initial total issuance. At the end of January 2019, it had destroyed 4 billion CETs (single destruction volume peak) at the end of this quarter. The number of CETs to be destroyed is 3,422,983.56.

4.2.2 Application scenarios
The current usage scenarios of CET are discounted platform transaction fees, VIP services, special activities rights and interests, CoinEx Chain internal circulation fuel, and use of external scenarios.
Deduction and discount of platform transaction fees
CoinEx platform users can use CET to deduct transaction fees when conducting transactions within the platform. At the same time, using CET to pay transaction fees can enjoy the exclusive preferential rates provided by the platform.
CET fee discount amount，Source：CoinEx; TokenInsight
Holding a certain number of CETs can make a user become a platform VIP user. Users can also use CET to purchase platform VIPs to obtain corresponding privileges such as discounted rates, accelerated withdrawals, and exclusive customers.
Special activity rights
CET holders can enjoy special rights and interests in platform marketing activities, such as participating in the airdrop of tokens on the platform or accelerating opportunities for high-quality projects.
CoinEx Chain built-in token
CET will serve as a native token of CoinEx Chain, circulate and serve as fuel in CoinEx Chain, and users can also use CET to invest or trade other digital assets. In addition, CET can also serve as transaction fees and function fees (issuing Token, creating new trading pairs, account activation), etc. in the platform, and users can also participate in the campaign of validators by staking CET tokens.
CET is currently used as a circulation token as well for CoinEx DEX to issue tokens, create orders, Bancor, address activation, set address aliases, and other application scenarios.
In general, the types of application scenarios of CET are not plenty enough. In order to better develop the internal ecosystem of the platform, it is necessary to design and develop more CET usage scenarios and incentive mechanisms to increase the retention rate of users while adding new users.
4.2.3 Token incentive
As the native token of the CoinEx public chain, CET will be used as a block incentive to increase community participation after the mainnet of the public chain launched. The 315 million CET held by the foundation in the total CET issuance will be used to incentivize initial verification nodes and Staking participants.

5. Team & Partners
5.1 Core team membersAmong the core team members of CoinEx, the technical members account for a relatively large proportion. The technical team’s overall ability is good and the team members have different technical experience backgrounds including cryptography, underlying protocols, marketing, and operations. The team has rich blockchain industry experience, especially the chief developer, who has about 13 years of development industry experience.
