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.

Hi everyone. Pleased to be here! Thank you for taking your time to join me.
I’m the Chief Business Development Officer for TomoChain.
Educationally I graduated university with degrees in both Industrial Engineering and Economics from Georgia Tech, and later earned an MBA from the Wharton School of Business.
I grew up as a gaming addict and have a video game collection that is a bit unwieldy. Dozens of consoles and, at one point, over 13 classic arcade machines.
So, before crypto, I spent much of my profession in the gaming space. I was a Game Designer, Game Producer, and eventually Studio Head for a major games studio that was recently purchased by Rockstar Games. I have run my own game-related tech businesses as well.
I fell into crypto back in 2014, and over time it became a second passion of mine as I began to truly understand the value of decentralization. True ownership of data was not possible until Bitcoin came along and that is simply a powerful and game-changing message to a world structure built on an opposing foundation.
TomoChain is a Public Blockchain powered by Proof-of-Stake Voting. TomoChain launched into Mainnet 1 year ago in December 2018. It is secured by 150 Masternodes, of which I’m proud to be an operator myself. TomoChain is EVM Compatible and runs at a speedy 2000 TPS with a 2 Sec Blocktime. Gas fees are almost zero too.
Based out of Vietnam, TomoChain is Southeast Asia’s largest public blockchain. We are focusing on developing a full suite of DeFi products. We also have commercial and enterprise clients. TomoChain has a number of major crypto-partnerships including notables like Neo Blockchain, Chainlink and Crypto.com. Our Masternode network is run by some of the most recognizable players in the space as well, including Neo Global Capital, CoinGecko, HashQuark, KuCoin, and more large players are on the way.
TomoChain earned its place onto Binance.com with a fee-free listing last year by winning the BinanceDEX community vote in August 2019. Binance has written us up in a detailed Binance Research Report and awarded us the V-Label. We have also been in a number of their reports, including those related to Dapps and DeFi. We have been interviewed by Forbes.com official and had an in-person interview at NASDAQ, in the heart of Times Square, about TomoChain and our upcoming TomoX Protocol.
In China, specifically, we have been integrated into and have solid relationships with various blockchain players including HashQuark, HashKey, CoboWallet, Conflux, and many others. We launched an Ecosystem Development partnership with Neo Blockchain last December and co-hosted a meetup + workshop with them as well.
GEARED FOR REAL WORLD USE
Now, let’s talk about how TomoChain has been built for real-world use.
We’re looking at Payments & DeFi as low hanging fruit when it comes to user adoption and TomoChain is developing a suite of tools to support this. The biggest challenge for having users benefit from Blockchain on a day-to-day basis is how much friction is involved to acquire, store and use it. Even stable coins are dual currency systems. The Stablecoin and then the Native Token to pay gas fees. Blockchain is simply not user-friendly.
Our view is that the true solution for Blockchain adoption by the world is end-users shouldn’t need to know they are using blockchain technology at all. It should be a hidden technology layer, similar to payment processor settlements or even the internet distribution centers/routers that power this very AMA we’re all participating in right now. Do we need to know the underlying technology infrastructure to use them? Nope.
We are developing a system to hide this friction, so the TomoChain blockchain can be integrated into real-world applications that you use every day on mobile or web.
There are 3 protocols that we are building to enable this future: (1) TomoZ: Zero Friction (2) TomoX: The DEX Protocol (3) TomoP: The Privacy Suite.
TomoZ: Zero Friction - Our TomoZ protocol is a core starting point to the solution for mass market use of blockchain technology. TomoZ: Zero Friction allows for token issuance and use by having gas fees paid by the token itself. That means you don’t need TOMO to send transactions. You don’t even need to know you’re using the TomoChain blockchain.
So you could buy a cup of coffee at a café using loyalty points that are TomoZ tokens. The customers redeem for their coffee or earn it, but they don’t even have to know it’s a blockchain token which they actually own.
This approach is structured to enable the next million-plus users to utilize blockchain as a technology layer. After all, the real value of any Blockchain is in its utilization of high-quality transactions.
Now, TomoZ transactions aren’t FREE. It actually does use TOMO, but that’s hidden from the end-user. The way it works is that the token issuer deposits a small amount of TOMO into a pool. Every time the token is sent, TOMO is taken from this pool to pay the Masternodes.
The key is that the end-user doesn’t need to get involved with internal workings, which is why we call it the Zero Friction protocol
Now let’s talk about TomoX: The DEX Protocol
TomoX is an upcoming DEX Protocol that allows anyone to launch their on permissionless Decentralized Exchange in minutes. It requires very little technical knowledge making it a near turn-key solution.
TomoX is the fastest DEX experience since it’s a Layer 1 protocol. This means it’s run and secured by the entire TomoChain network. Our Masternodes manage the DEX instructions directly, rather than other DEXs that operate as a Layer 2 protocol. What this means is TomoX DEXs will operate at about 50x faster than a typical 0x exchange. That significantly improves the end-user experience.
TomoX DEX operators have access to a shared liquidity pool across all DEXs. That means a user buying on one DEX can be matched with a user selling on another DEX. Of course, Operators can customize and choose which tokens to include.
TomoX is fully decentralized since the Order Book is on-chain. Many other semi-decentralized exchanges store the OB on a centralized service in order to speed up the execution. That means there is a centralized point of weakness for them. TomoX minimizes custody and security challenges that centralized exchanges have too since all users are always in possession of their assets.
TomoX is currently in testnet and you can checkout TomoChain’s own DEX, aptly called TomoDEX, here: https://dex.testnet.tomochain.com/
Here is a link to get some free Testnet TOMO that can be used on the testnet version of TomoDEX: https://faucet.testnet.tomochain.com/
And finally, there is TomoP: Privacy Suite - TomoP is currently in testnet and is going to be the FASTEST way to send tokens privately. 2-4 seconds fast!
Any token issued on TomoChain will be able to utilize TomoP to send privately and anonymously. And that’s not all. We are including access to wrapped BTC, ETH, USDT, and other tokens that can also utilize the blazing speed and privacy that TomoP will offer.
Dapp privacy is a major part of TomoP. It is going to allow for the creation of Dapps to be built to handle customer data with true privacy, including from the Dapp operators themselves. This can jumpstart a new wave of applications geared towards hiding user information, transactions, assets owned, etc.
We are issuing a new token standard (TRC21p) which will be purely private. The only data available will be on its token supply. Token issuers can optionally provide auditing access to enforcement authorities to meet regulatory compliance. What this means is if the next Global PayPal/Skrill/Alipay competitor can build their service right on TomoChain and meet the most basic criteria required to stay above board in many jurisdictions.

Questions from the host
1. It’s been stated that TomoChain was on track to be a cash flow positive business, is it currently cash flow positive? What services or products is it offering to bring in this revenue?
Yes, absolutely. Our plan is to be cash flow positive this year. This really goes back to the level of experience our executive team has. Everyone is seasoned, having come from different fields, in big business and startups. Before the crazy boom of ICOs and IEOs, raising funding for traditional startups required considerable proof that there was market fit, that there were actual customers to drive revenue, and a model for growth.
We knew that TomoChain’s funds raised during the ICO were for a space that has yet to prove itself so the company had to be smart in budgeting for an uncertain future. And part of that initial preparation was selling much of the ICO proceeds into fiat. Something MANY blockchain startups did not do, largely due to ambitious teams that are also headed by very inexperienced leaders. So while the bubble burst, we had capital to continue operations and to even scale it.
And, we ARE running a business. A sustainable business requires us to identifying areas to generate income in order to minimize risk and to sustain the business in the long term. So we do both consulting and services work by helping clients to develop wallets, launch tokens (Orbyt), build exchanges (AIS), and of course enterprise solutions on the blockchain of which we have clients based out of Japan and in the Middle East using blockchain for traceability solutions across various industries from automotive, healthcare, and food.
2. What is the most strategical step TOMO is doing to bring adoption of TOMO coin to our daily lives?
Empowering businesses with a truly scalable blockchain that can be used by thousands and millions of users. We see user adoption of blockchain coming from businesses that base their solutions on blockchain technology. And, TomoChain has a number of real income-generating companies that have built on us, from exchanges to payment services to enterprise clients. Not bad for 1 year I say, especially during a stagnant market. Here are some examples.
UcarPac – A Top 10 User Car company in Japan is building traceability solutions on the blockchain. We completed a POC at the end of last year. After the assessment, the client decided it was solid and commissioned Phase 2 to expand the development of the project for commercialization purposes
Triip Protocol – Triip is a destination service for travelers to book vacations powered by Blockchain. Triip is a Shark Tank Vietnam alumnus, and the first ICO on TomoChain. Users can book tours and staycations using Triip or TOMO tokens.
WisePass – A service that sells subscription services to get discounted Starbucks, Singha Beer, and even makeup (of all things) integrated TomoChain as a payment solution
“Undisclosed Vendor” – Soon to be announced, a large player in the corporate gift giving business is also launching a Dapp on TomoChain to allow for them to make purchases with TOMO across thousands of items.
Maka - A peer-to-peer marketplace to conveniently buy/sell TOMO and other blockchain tokens using standard payment gateways, including e-wallets and bank transfers.
Coin98 – A local Vietnam crypto media company launched an App to allow for their community to earn their TomoChain token called C98 and use it for products and services geared around investors and gamers. The reception has been HUGE. 95,000 users and generating 500K+ transactions on our blockchain within 3 months of their launch! They are proving that innovative new business models can be adopted relying on and being blockchain specific.
3. Do you have any plans to collaborate with developers or attract more Dapps built on TomoChain?
We are today. Our founders run the largest Blockchain Developer community in Vietnam and we work with a number of them to help develop solutions on the blockchain.
Our team has held Hackathons a few times over the last couple years and we have done developer workshops too, including one with Neo Blockchain. And this year we are working closely with educational institutions to launch blockchain courses in Vietnam.
Every Dapp developer we work with is a partner. We try to provide as much support as possible, both technical and marketing. A number of Dapps are games on TomoChain and we hold contests regularly to promote the developers and their titles.
Since we are focusing on alleviating the friction of blockchain technology, we are building out an API that will make it even easier for developers to integrate blockchain into standard applications. This is intended to allow standard non-blockchain application developers to operate in an environment they are accustomed to while also having the benefit of blockchain technology accessible.
Onboarding more developers will take time. However, I’m confident we’re on the cusp of something wonderful in the coming years that will change the relationship between users and applications enabled by blockchain. Entirely new economic structures can be set up since it’ll be the users owning all of their data for the first time in digital history. And true ownership is a powerful motivator that can be harnessed by innovative blockchain businesses.

AX Trading LLC (AX), a technology-enabled registered broker-dealer and Alternative Trading System (ATS) operator, today announced a strategic partnership with Quant Network a pioneering technology company providing financial and regulatory technology as well as interoperability in financial services, payments and capital markets infrastructure. Through this partnership, Quant Network’s technology, Overledger a blockchain operating system, will enable universal interoperability for regulatory-compliant security tokens and digital assets to be traded on AX ATS, a regulated secondary trading market. AX intends to integrate Overledger to help foster the evolution of traditional capital markets infrastructure to facilitate the mass implementation of interoperable regulated digital assets. With the increased market adoption of digital assets and banking “coins” such as JPMorgan Coin, AX and Quant Network are at the forefront to enable the transferability and movement of digital assets. George O’Krepkie, AX CEO said: “we look forward to partnering with Quant. Their technology will allow our blockchain agnostic security token exchange to communicate seamlessly with issuers, traders, investors, and regulators across different blockchain protocols. This is a key technological breakthrough that will help us bring the benefits of security tokens to Main Street and Wall Street.” It is expected that the first interoperable digital asset offering may commence as soon as January 2020, and that the AX Trading ATS may be ready to enable and list interoperable digital assets and securities in 2020.Let’s have a closer look at what that means to truly appreciate the significance of the partnership by covering the basics for those not familiar with wall street.
What is an Institutional Investor / Trader?An institutional investor is an organization that invests on behalf of the organization's members. They consist of hedge funds, banks, investment banks, pension funds, insurance companies, endowment funds, or any other type of money management firm.
Institutional investors account for about three-quarters of the volume on the New York Stock Exchange (which alone handles more than $20 Trillion a year in volume). In the US, Institutional investors own about 80 % of the total market value of the equity (stock) market, which globally is worth more than $73 trillion.
Wall Street refers to the institutional investors I mentioned above whereas Main Street refers collectively to members of the general public who are not accredited investors and the overall economy as a whole.
Whilst the Equity Market is huge, Institutional investors also invest in other securities which are prime to be tokenised such as Real Estate Market (Globally worth $217 trillion), the Debt Market (Globally worth $215 trillion) and the Derivatives Market (Low end estimates at $544 trillion and high-end estimates at $1.2 quadrillion). All of which makes the current market cap for cryptocurrencies look like a drop in the ocean.
Who are AX Trading?AX Trading is a SEC-registered broker-dealer and Alternative Trading System (ATS) Operator. They are a member of FINRA (Financial Industry Regulatory Authority)and SIPC ( Securities Investor Protection Corporation) regulated authorities. The SEC has some of the most stringent regulations in the world for listing securities and there are fewer than 50 SEC-registered Alternative Trading System Operators in the United States, of which only a handful are currently implementing Digital Assets. Others are awaiting regulatory approval with Coinbase, Circle etc are all looking at getting into this huge market.
AX Trading have investors and sponsored brokers including the likes of Credit Suisse, (a multinational investment Bank and Financial services company worth $27.5 billion). AX currently have over 800 Institutional traders (these are not individuals, but corporations such as hedge funds, banks, investment banks, pension funds, insurance companies, endowment funds etc).
AX Trading have also partnered with Euronext, the largest Stock Exchange in Europe with a market cap of $4.65 trillion as of 2018, in the creation of Euronext Block which utilises AX Trading.
What is an Alternative Trading System?An Alternative Trading System (ATS) is an SEC-regulated trading venue which serves as an alternative to trading at a public exchange. ATS account for much of the liquidity found in publicly traded issues worldwide. They are known as multilateral trading facilities in Europe, electronic communication networks (ECNs), cross networks, and call networks
AX is the world’s first “Electronic Trading Network” (ETN) where institutional traders can proactively connect and trade with other counterparties in a secure environment. Unlike traditional stock exchanges/ECNs that show orders to everyone and traditional dark pools/crossing systems that show orders — presumably — to no one, AX allows institutional traders to pick and choose WHOM they want to notify and also WHAT information they want to share with them.
Institutional investors may use an ATS to find counterparties for transactions instead of trading large blocks of shares on national stock exchanges. These actions may be designed to conceal trading from public view since ATS transactions do not appear on national exchange order books. The benefit of using an ATS to execute such orders is that it reduces the domino effect that large trades might have on the price of an equity.
How does AX Trading Work?The AX Trading process begins when one trader sends an “initiated” order to AX. The order can be routed to the AX ATS via one of our broker sponsors such as Credit Suisse. The initiated order triggers a “Call Auction” on AX, a period of time when the order will rest in AX to be matched against other orders from auction responders.
The Initiator of an AX auction decides who they want to invite to participate in the auction, whether they be all 800+ institutional members or targeted to specific ones, as well as how much info they want to disclose about the order. Based on these instructions, the AX ATS then notifies the members inviting them to participate in the trade.
The invited members can then participate in the trade by either placing buy orders of their own or placing sell orders. At the end of the AX auction period, all orders are brought together, and a match is performed.
In the traditional, continuous market with displayed bids and offers, traders are often chasing liquidity. In other words, the price may move away from them the more they buy or sell to what is commonly called “market impact.” On AX, the advantage of their call auction model is it brings liquidity — in the form of participant orders to the buyer rather than them chasing liquidity.
What is a Security Token?Security Tokens are different than Utility Tokens or Cryptocurrencies. A security token is a digital representation of a traditional security. It may represent shares in a company, interest in a fund, real estate, art collectables, or essentially any asset a party can own. Anthony Pompliano wrote an article explaining tokenised securities in more detail which you can see here
Security Tokens are digital assets subject to federal security regulations. In layman terms, they are the intersection of digital assets (tokens) with traditional financial products — a new technology improving old things. If cryptocurrencies like Bitcoin are considered “programmable money” then you can consider Security Tokens a version of “programmable ownership.” This means that any asset with ownership can and will be tokenized (public & private equities, debt, real estate, etc).https://preview.redd.it/21cz6zvus0m31.png?width=569&format=png&auto=webp&s=883eb844e1061cddd585903549dde829098765c2
Quant Network community member David W also wrote an excellent piece on the benefits of tokenisation of assets in a lot more detail than what I will briefly cover here and strongly recommend you check it out.
The Tokenisation of assets is therefore inevitable, because it is a better way to record, exchange and monitor asset ownership for all parties involved. The amounts at stake represent many hundreds of trillions of US dollars
What are the benefits of a security token?
Security Token Issuance PlatformsSecurity token issuance platforms allow issuers to issue Security tokens that represent the security such as Shares in their company etc in return for capital. This is known as a Primary Market. Importantly it’s not just the issuance that they look after, it’s the whole life cycle of a digital security to ensure they remain continuously in compliance as they are traded etc. They also provide reporting to the issuer so they can see who owns the tokens and what dividends to pay out.
Securitize are one of the leading security tokens issuing platforms. They have created the DS Protocol, a blockchain agnostic protocol for security tokens which manages the whole lifecycle of a digital security, ensuring it remains continuously in compliance. They have issued a number of security tokens on the Ethereum network as well as recently working with IBM to tokenise the Corporate Debt Market (worth $82 Trillion). On the back of this they joined Hyperledger, an open source project which includes Enterprise blockchains such as Hyperledger Fabric which IBM is heavily involved with.
They recently also became the first SEC-registered transfer agent, which means Securitize can now act as the official keeper of records about changes of ownership in securities.
There are many companies in this sector which are utilising various blockchains, Other examples include:
Trading VenuesWhilst the issuance platforms above generally also include their own exchange where the token can be traded on, secondary markets such as those offered through traditional stock exchanges and Alternative Trading Systems provide significantly more liquidity.
Traditional Stock Exchanges have been very active in blockchain with some going through proof of concepts, to those like SIX SDX Digital Exchange which is due to launch later this year. They are using various blockchains and cover the full process from Issuance, Trading and Post Trade / Settlement services. I have briefly outlined which blockchain they are using / testing with along with source to read more about it below:
Post Trade — Central Security DepositoriesSituated at the end of the post-trading process, CSDs are systemically important intermediaries. They thereby form a critical part of the securities market’s post-trade infrastructure, as they are where changes of securities ownership are ultimately registered.
CSDs play a special role both as a depository, involving the legal safekeeping and maintenance of securities in a ‘central depository’ on behalf of custodians (both in materialised or dematerialised form); as well as for the issuer, involving the issuance of further securities by issuers, and their onboarding onto CSDs’ platforms.
CSDs are also keeping a number of other important functions, including: dividend, interest, and principal processing; corporate actions including proxy voting; payment to transfer agents, and issuers involved in these processes; securities lending and borrowing; and, provide pledging of share and securities.
Blockchain technology will enable real-time settlement finality in the securities world. This could mean the end of a number of players in the post-trade area, such as central counterparty clearing houses (CCPs), custodians and others. Central Security Despositories (CSD) will still play an important role according to reports:
“CSDs could have an important role to play in a blockchain-based settlement system. As ‘custodians of the code, CSDs could exercise oversight of, and take responsibility for, the operation of the relevant blockchain protocol and any associated smart contracts.” Euroclear Report
Another group of 30 central securities depositories (CSDs) in Europe and Asia are researching possible ways to “join hands” in developing a new infrastructure to custody digital assets. The CSDs will attempt to figure out how to apply their experience in guarding stock certificates to security solutions for crypto assets.
“A new world of tokenized assets and blockchain is coming. It will probably disrupt our role as CSDs. The whole group decided we will be focusing on tokenized assets, not just blockchain but on real digital assets.”
You can read more about how blockchain will affect CSD’s here
Examples of CSD’s in blockchain
The Importance Of Interoperability
The evolution of DLT and the wide adoption across industries and across different market segments is resulting in many different ledgers networks, but the ultimate promise of DLT can only be realized when all ledger networks can seamlessly interoperate. — from the recent DTCC whitepaper with AccentureIt’s clear from the above that interoperability will be crucial in order to unlock the true potential of Distributed Ledger Technology. Issuance platforms will seek to interoperate with as many secondary exchanges as possible to provide maximum liquidity for issuers. Issuance platforms and secondary exchanges are each using a wide range of different blockchains that all need to interoperate as part of the trade process. CSD’s will also need to have interoperability between other CSD’s as well as to the secondary exchanges (again each using different blockchains).
Enter Quant Network’s OverledgerQuant Network’s blockchain operating system, Overledger, provides interoperability between any current and future distributed ledger technology as well as easily connecting Off Chain / Legacy networks as well as plans to connect directly to the Internet. Within 10 months it has proven it can provide interoperability with the full range of DLT technologies from all the leading Enterprise Permissioned blockchains such as Hyperledger, R3’s Corda, JP Morgan’s Quorum, permissioned variants of Ethereum and Ripple (XRPL) as well as the leading Public Permissionless blockchains / DAGs such as Bitcoin, Stellar, Ethereum, IOTA and EOS as well as the most recent blockchain to get added Binance Chain. All without imposing restrictions on connected chains, being Internet scalable and able to easily integrate into existing networks / infrastructure.
Overledger a blockchain operating system, will enable universal interoperability for regulatory-compliant security tokens and digital assets to be traded on AX ATS, a regulated secondary trading market. AX intends to integrate Overledger to help foster the evolution of traditional capital markets infrastructure to facilitate the mass implementation of regulated digital assets. With the increased market adoption of digital assets and banking “coins” such as JPMorgan Coin, AX and Quant Network are at the forefront to enable the transferability and movement of digital assets
Overledger enables Universal Interoperability where digital assets can move across blockchains so that they can interact with smart contracts on different blockchains. It does this by locking the asset on one blockchain and then representing it on another blockchain either by creating a representing token or representing it via metadata. This will enable all of these different parties such as Issuance platforms, Exchanges, CSD’s, traders etc to move the digital asset from their respective blockchain onto AX Trading’s platform for secure, immediate and immutable trading to take place. Potentially it would even allow Digital Assets / Securities to settled on a public permissionless blockchain such as the recently connected Binance Chain in a completely safe, secure and compliant way.
Regulators would be able to run a node and view transactions in real time ensuring that compliance is being kept. Potentially they could also benefit from using Quant Networks Multichain Search capability http://search.quant.network/ to be able to fully track assets as they move across blockchains.
George O’Krepkie, AX CEO said: “we look forward to partnering with Quant. Their technology will allow our blockchain agnostic security token exchange to communicate seamlessly with issuers, traders, investors, and regulators across different blockchain protocols. This is a key technological breakthrough that will help us bring the benefits of security tokens to Main Street and Wall Street.”
SecurrencyAX Trading have also partnered with Securrency (who have previously tokenised over $260 million in real estate assets). Securrency provide a protocol that enables security tokens to remain in compliance regardless of what blockchain the token is on. Due to the layered approach that Overledger has adopted from the learnings of TCP/IP, this protocol can be easily integrated on top of Overledger to enable security tokens to move across blockchains as well as ensuring they remain in compliance with regulations programmed into the token.
Delivery vs Payment (DvP)
A DvP transaction involves the settlement of two linked obligations, namely the delivery of securities and the payment of cash. DvP avoids counterparties being exposed to principal risk, i.e. the risk that the seller of securities could deliver but would not receive payment or that the buyer of securities could make payment but would not receive delivery. Following this requirement, a DvP securities settlement mechanism has to ensure that the delivery of securities and the payment of cash are linked in a way where one leg (obligation) of the securities trade is conditioned to the final settlement of the other leg (obligation) of the trade. Thereby final settlement is defined as “the irrevocable and unconditional transfer of an asset or financial instrument, or the discharge of an obligation by the FMI or its participants in accordance with the terms of the underlying contract”. — STELLA — a joint research project of the European Central Bank and the Bank of JapanWe have seen how Overledger can provide interoperability for the securities to move across Issuers platforms, integrate with Stock exchanges, Central Security Depositories and AX Trading. Now we need to be able to ensure that payment is guaranteed and in a way that offers immediate settlement which is irrevocable. To do this we need to represent FIAT on the blockchain so that it can interact with smart contracts and settle transactions on the blockchain.
J.P.Morgan’s CoinJ.P.Morgan is the largest bank in the United States and ranked by S&P Global as the sixth largest bank in the world by total assets as of 2018, to the amount of $2.535 trillion.
J.P. Morgan was the first U.S. bank to create and successfully test a digital coin representing a fiat currency. The JPM Coin is based on blockchain-based technology enabling the instantaneous transfer of payments between institutional clients.
With J.P.Morgan’s $2.6 trillion balance sheet, expertise in blockchain and global payments network, J.P. Morgan can seamlessly and securely transfer and settle money for clients around the world. J.P. Morgan are supervised by banking regulators in the United States and in the international jurisdictions in which it operates.
How does JPM Coin work?A Buyer purchases JPM coins in advance which get represented on the Permissioned Quorum blockchain ($1 =1 JPM Coin). Quant Network’s Overledger could then provide interoperability to lock those tokens on Quorum and represent those onto another blockchain / AX Trading’s Network. By being able to represent securities and FIAT on the same blockchain (even though the underlying assets are on different blockchains) this provides instant finality / settlements to occur.
Once the seller receives the JPM coin in exchange for the securities they have sold they will be able to redeem them for USD. It also doesn’t necessarily mean that they have to have a JP Morgan account to redeem them, you could imagine in the future that the Bank instead redeems the JPM Coin and credits the users account. Similarly the buyer of the security token redeems the represented token and unlocks the security token on the original blockchain.
You can read more about JP Morgan’s Coin here as well as its use cases
J.P Morgan is betting that its first-mover status and large market share in corporate payments — it banks 80 percent of the companies in the Fortune 500 — will give its technology a good chance of getting adopted, even if other banks create their own coins. “Pretty much every big corporation is our client, and most of the major banks in the world are, too,” Farooq said. “Even if this was limited to JPM clients at the institutional level, it shouldn’t hold us back.”Overledger enables different securities tokens / digital coins representing FIAT currencies to be brought together from the various permissioned / permissionless blockchains onto one platform where trading / settlement can take place. Overledger is the only technology that can do this today across the leading permissioned and permissionless blockchains as well as existing networks, all in a secure, scalable and easy to integrate way.
Quant Network are working with AX Trading to bring more digital assets, securities and tokenised assets to their existing 800 institutional traders in an already live and connected FINRA and SEC regulated exchange. AX Trading is not just about trading securities but other digital assets such as Bitcoin, Ethereum and potentially even Quant in the Future.
This is a multi-trillion dollar market with huge global enterprises, traditional exchanges and global banks are all adopting DLT at a rapid pace and going into production at scale in a matter of months, examples include the NYSE Bakkt launching Bitcoin futures later this month, Swiss Stock Exchange ($1.6 Trillion market Cap) is due to launch their digital exchange running on Corda (SDX) by the end of the year. The DTCC are due to launch their Trade Information Warehouse which processes $10 Trillion of cleared and bilateral derivatives by the end of the year. JP Morgan who transfer $6 Trillion every day are due to launch their JPM coin at the end of year and AX Trading is due to offer their first digital asset by January 2020.
Quant Network’ Overledger enables the bridging of traditional finance infrastructure with the new decentralised finance infrastructure DeFi of the future, helping to redefine Wall Street and Capital Markets.
George Cao :Let’s welcome lambda team . Xiaoyang and Lucysubmitted by BitMax_Support to BitMax [link] [comments]
Lambda: Hello friends from BitMax ~~ I am Lucy Wang, Co-founder and CMO of Lambda. I am very happy to e-meet with you here and thx for George's invitation. I on behalf of Lambda wish all of you a merry Christmas and prosperous new year in 2019
George Cao: Great. I am a bit surprised to see a big volume day yesterday Christmas. Seems our users didn’t take a break even on holidays :)
Lambda: I'd like to take this opportunity to introduce myself first, I have over 14 years of progressive career development with global leading enterprise software / service organizations as well as VC-backed start-up ventures, including HP, Oracle, and SAP. Before Lambda I was CMO/GM at two enterprise SaaS start ups in China backed by top VCs.
And my partner Mr. He Xiaoyang, who is the founder of Lambda, he is a well-known expert in infrastructure and open source software in China. Prior to Lambda, he was the co-founder of OneAPM, a fast-growing infrastructure software focusing on ITOM (IT operation management) in China. OneAPM is known as the “New Relic or AppDynamics of China” and the company has received strong VC backing from Matrix Partners, Chengwei Capital, and Qiming Venture. Prior to his entrepreneur experiences, Mr. HE worked at BEA as a R&D software engineer. In addition, Mr. HE is also a blogger with strong following in China and some of his articles have been published by major media such as Forbes China, 36Kr, Sina, etc.
Lambda idea was born at the end of year 2017 and the product development started from the beginning of 2018. Now let me talk about Lambda idea and what we do
Lambda, is the leading decentralized infrastructure project providing secure, reliable, and infinitely scalable decentralized storage network that enables data storage, data integrity check, security verification, and marketplace for storage-related services on the Lambda Chain Consensus Network.
In recent years, there have been frequent data leakage problems in major Internet platforms at home and abroad, and even business giants such as Facebook and Marriott have not been spared. Returning the value of data to data owners is an inevitable trend in line with human pursuit of freedom. The block-chain technology with P2P features provides an opportunity for this, and this area will be highly valued by the industry in the next few years. Lambda is the only provider of block-chain storage infrastructure projects in China. It is sometimes referred as “File-coin of China”or “File-coin 2.0”.our vision is to return the value of data to the data owner, with this vision in mind, our mission is to promote the decentralization of the Internet, with the goal of creating a storage infrastructure for the next generation of block-chain.
After the Lambda project launch in early 2018, it has received strong support by well-known strategic and financial investors including Bitmain, Viking Capital, FBG Capital, Bluehills, Zhen Fund, FunCity Capital, Ceyuan Digital Fund, BlockVC, INBlockChain, DATA Foundation, Bitcoin World, Reflextion Capital, etc. To date, Lambda has received investment funding in excess of $10M.
n all the existing decentralized storage projects that are aiming to give a solution to this problem worldwide, Lambda is the first ever to announce its LPDP ( Lambda Provable Data Possession )
George Cao: I see we share several investors in common, So 2019 q1-q2 will be a big milestone for lambda
Lambda: Provable Data Possession (PDP) and Proofs of Retrievability (POR) are critical to efficient decentralized data storage and its implementation, which is the essential difference between centralized network projects and real decentralized storage. Prior to Inter-planetary
File System (IPFS), Lambda launched its minimum viable product (MVP) of core functions in the third quarter of 2018, and has been continuously upgrading and optimizing this in block-chains in a multi-role environment.
File-coin is our main competitor, here is a chart shows the progress comparison FYI
For those who have interest to know more about Lambda's technical innovations, they can be find in our keep updating FAQ document posted on Medium, and I copied her FYI
1.Innovatively designed the Validator role which provides verification service for storage proof and the Validator replaces storage miner as the full-time storage proof result verifier, this greatly improves the performance of the storage and retrieval system.
2.In response to the limitations of the PDP algorithm, Lambda innovatively created a consensus network on the block-chain and used the validators role to replace the "TPA" in the PDP algorithm.
3.Innovatively modified the PDP algorithm from synchronous to asynchronous communication, which greatly reduces the communication traffic for Challenge in the system. Use of chain data as a random seed for storage miners to issue Challenge themselves addresses the randomness of TPA challenges.
4.Innovatively upgraded the PDP algorithm from periodic verification to a verification set generated by the miners to submit the verification result at one time, and fully realize the Proof-Of-Space-Time verification.
on top of all the technical, Lambda creates a consensus network where data can be stored, storage space can be rented on the basis of a marketplace built on block-chain.
In the Marketplace, the transaction process is: storage miners pledge hard disk sectors to the consensus network, and place orders and sell their own storage space in the Marketplace; storage users initiate purchase requests, complete the matching of storage requests through the Marketplace, and store data in the space of the storage miners.
Different from other block-chain applications, Lambda is a storage mining project, we have miners mine on Lambda network. Earn LAMB tokens by contributing on the network, and users who have data storing requirements pay Lamb tokens to purchase services accordingly.
The price of Lamb token not only rely on the exchanges but also supported by our miners who are doing works on the network.
There are four roles in the Lambda mining network: storage miners (providers of storage space), verification miners (ensuring the integrity and security of data and packaging transactions), retrieval miners (providing download bandwidth), and users (storage buyers). 1024 verification miners promoted from storage miners constitute the Lambda-chain consensus network. So you will see three types of miners serve our users from all over the world.
The key milestones we are looking at is the launch of test-net, where miners can start mining and earn testing Lamb tokens, the date will be around end of Jan. 2019 and main network will go live in Q2, 2019, most likely in Apr.
Regarding our partnership, In the academic field, we have established a strategic partnership with Beijing Institute of Technology (BIT), which is well known in China for its engineering and computer science research programs, to conduct research into centralized storage.
In the commercial field, Lambda has established a strategic collaboration with IOST, a well-known public blockchain project, and Perlin, a super computing platform, and started to conduct pilot projects for decentralized application (DAPP) companies such as DATA and BCV. Lambda also has close ties to many leading Internet data centers (IDCs) in China. They join the Lambda network as miners and take advantage of their surplus server capacity to engage in the Lambda network ecology.
Q: Will the rest of the code be open sourced? If so when ?
Lambda: we have released the codes of core function module, the test net codes will be released gradually in Jan. pls stay tuned with our official github
Q: What can Lamb tokens be used for?
Lambda: Lambs are tokens in the Lambda ecosystem, which are mainly used in the following scenarios:
A. Users of services in the Lambda ecosystem have to pay with Lambda tokens.
B. Providers of storage services in the system have to pledge a certain number of tokens.
C. Verification nodes in the system have to pledge a certain number of tokens.
D. Verification nodes can obtain a certain number of tokens as accounting rewards.
E. Storage nodes get a certain number of tokens based on their storage capacity and their service level agreements (SLAs).
F. Other roles in the Lambda ecosystem can also obtain a certain number of tokens based on their contributions.
Q: What more incentives does miner gets to mine or rent storage on Lambda?
Lambda: every miner stars from storage miner on Lambda network, they get paid by providing storage space, when their business getting bigger, system will select the top 1024 storage miners and promote them to validator, who will get block generation rewards from system.
Q: how are the 1024 miners selected? Doesn't this become more centralised?
Lambda: we did a survey to the Chinese miners, they mainly fall into two groups, either are waiting FileCoin to go live with purchased mining machine idle at home or they are doing hard drive or graphic cards mining, which has a high requirement to the hardware standard. To mine on Lambda, you need a mining machine ( computer ) that has big storage space ( because the bigger the higher probability you'll be promoted to be a validator ) and the connection to the internet
Q: How much is initial supply?
Lambda: Lambda did two rounds of fund raising, private investors have a lock up terms of 2+4+4 meaning the first 20% of tokens will only be released 2 months listing on exchange. so on the day one listing till 2 months there will be only around 0.5% initial circulation, and after 2 months, 5% in total. in addition to that, as we are recruiting miners to join our network, actually ppl have been in a situation where they can't wait to mine on our testnet. with the mining mechanism we have, miners need to buy Lamb token to get their mining work started, because a certain amount of pledge need to be made
Q: What partnership will lambda and bitmax have in the future?
Lambda: We value the way BitMax doing things and care about projects, we feel like we found the right exchange to be listed, in particular an initial listing. we will work with BitMax and do some joint campaigns to boost the community
George: We have great chemistry with lambda team.
Q: And are you still primary list in there, I heard the list was delay? Is it related to Huobi?
Lambda: you are right, it is related to Huobi, but one thing you can be assured of is that our initial listing on BitMax wont change, but most likely a joint listing with Huobi.
Q: what about the time of primary list?
Lambda: we will primarily list very soon, we are targeting end of this week, now we are in the middle of some technical integration with Huobi
George: We can assure everyone that our team will do our best to protect our investors and serve our listing projects. The promise does not change whether or not if we co-list with huobi.
Q: We get reward to mine ? Any incentive? For testnet
Lambda: Yes, you have two ways obtain Lamb tokens, buy from exchange and earn more from mining, but firstly you have to buy Lamb on BitMax haha. Are you asking the reward from testnet by mining on it? yes, you will get test Lamb token, and they can be redeemed to Lamb token with a ratio that will be specified shortly. on Lambda official website www.lambda.im, we have whitepaper, besides that we also have economic whitepaper to explain how the lambda economic system runs, on Dec. 28 we will launch our yellow paper where we will demonstrate the detailed technical realization and all the parameter setting for mining on Lambda
Q: What are the implications if a miners rig goes offline or they decide to stop?
Lambda: If miners rig goes off, they will not get the reward from the corresponding generated block, if they do cheating there will be punishment from the system, and if they decide to quit, the pledge will be returned
Q: Lambda planning to have own FS?
Lambda: Yes, FS and consensus network is separate. validators and marketplace are on the consensus network, while Files are in the File System.
Q: Is Lambda GDPR friendly?
Lambda: yes, we are
Q: Hi can u explain what’s the requirements of decentralized data . Do You think big companies will like to use lambda services .... or it’s for medium level enterprises as big companies will go for their in house system with their reliable nodes ...
Lambda: this is a good question, from I seeing it, ppl call out the protection of privacy, it is a trend and it takes steps. Lambda has two big groups of prospects users, one is DAPPs, another is the general industries such as big data, AI, IoT, Games, Financial, etc, as long as they need massive data storage demand, Lambda has the opportunity, data storage is expensive, especially when we are talking about big data, a lot of companies will value the cost in this area very much. currently we have lighthouse customer like DATA, BCV, VVshare, in the very near future, a game that is developed by Lambda team will also go live on Lambda network. from the BD perspective, Lambda will create a satellite network ( you can take it as channel network ) to bring us customers, we have a few reaching out to us already
Q: Why suddenly launched on Huobi
George Cao: I believe lambda team has its own consideration. Projects esp in bear market are facing pressures from different parties. Investors users exchanges. Not everything is under projects control. What we can do as an exchange is to stand by our partners and fully support them down the road
Lambda: thx for the answer
Q: I think you have made a great choice working with bitmax. Bitmax have really helped push new
coins and their site in general with good PR, marketing and reward/airdrop promotions
Lambda: strongly agree with you
Q: GDPR has taken over the EU and the UK so that is very important
Lambda: you are right, so we see to be GDPR friendly, which is one of our differentiator from FileCoin
Q: Being GDPR friendly , European market is a go for lambda
Lambda: I have this plan to develop European market by having a Raspberry program, it is still in planning.
George Cao: Let’s take a last question and move to lambda community:) And as usual we will pick 3 best questions. We will send out 1000 800 and 500 btmx. @lambda do you want to pick 3 questions ?
Q: Recent partnerships are interesting , can you tell us about coming q1 2019 both in terms of technical and marketing developments ?
Lambda: from Marketing side, we are focusing on Chinese miners community and potential European market ( like I said still in construction ) Korean market is another, and US market to go along our compliance path, Lambda has been strictly abide by the regulations. from technical side, the most important task we are targeting is the main network launch as planned
George Cao: Thanks everyone for your time. It’s a great ama as usual. We do have the best community. We will pick 3 winners and we will announce here after we finish ama in lambda community
Lambda: thank you all for your time to participate the AMA, I had a great time with you, see you friends and have a nice day.
George Cao: Hello everyone, Merry Christmas:)
Lambda: Hello Lambdos. Today we have George, the founder of BitMax to join us for the AMA. Let's give him a warm welcome to do a introduction of BitMax
George Cao: I am George Cao, founder of bitmax. I am happy to take the opportunity to talk to everyone here. Thanks to the lambda team. Let me start with a brief introduction about us.
Bitmax.io (btmx.io) is an exchange founded by a group of Wall Street veterans. Unlike most projects, we are kinda of old :) core team are in their 30ish - 50ish. The 10 founding member have combined of 150 years of Wall st experience. I have 10+ yrs of high frequency trading experience therefore I know the trading system well. That’s why our match engine can handle 400k tps per second vs huobi 1000 tps. We want to build an exchange that is transparent, robust, and efficient. While our system is the best in class, we offer the lowest trading fees. We believe the current high commission will not sustain and we will see consolidating of the exchanges with better depth and liquidity and lower commission. We are happy to partner with lambda, one of the best projects in 2018. We are committed to serve the project and the community. Alright, I am ready to take questions. Anything you can ask, as tough as you want :)
Q: Haha nice platform.
George Cao: Thanks. We are young as a platform but we are working to deliver the best
Q: I see reverse mining is new , I used many other mining exchange but all have normal mining . How does reverse mining works?
George Cao: Reverse mining is an innovative approach that helps the exchange and the project in several ways. 1) the concept of reverse mining is by providing liquidity to the exchange, you get a rebate and deduct out tokens from your account of the same valued. You can think of a otc sell our. 2) the benefit is it removes lots of sell pressure from the secondary market. And provides a strong support for the token price. 3) it introduces lots of liquidity to the exchange and benefits all traders
Q: The BTMX used in reverse mining are locked forever?
George Cao: Yes so the total number of tokens are always reducing your
Q: I've really been enjoying using the bitmax exchange so far especially with the low fees and data usage rewards. Does the exchange plan to bring in a shorting function in the near future?
George Cao: Yes we will have margin and futures trading
Q: It was supposed to December right ?
George Cao: We postponed our margin to Jan. The reason is we want to be more careful on protecting margin call protections.
Q: Margin trading and futures is important for BTMX price to drive up
George Cao: Totally agree
Q: Does BitMax have any activities on New Year's Day?
George: We do have multiple promotional events. Including but not limited to airdrops. Please visit our website and stay tuned
Q: I saw the whitepaper of bitmax, can you talk more about your dividends the formula is really hard for me ?
George Cao: Sure 80% of our commission goes to our fee pool. 1/180 of the total pool will be distributed daily. As long as you are a token holder, the current rate we pay is over 100% annually
Q: Oh I see, so the dividends will be smooth, great idea.
George Cao: Yes unlike other mining exchanges have huge volatility on div we smooth our curve
Q: I've also heard there is a mobile app in the works, is this likely to be released in the near future?
George Cao: Almost done. Beta version is in testing
Q: What about the north American, will it be available in the future?
George Cao: We more cleared our legal path for fiat trading in us. Q1 2019 we will launch in the us
Q: Great news I think this will bring a big volume.
George Cao: Yes agree. Our team is excited as well
Q: With promotional Airdrops that require a certain amount of the BTMX token to be held such as The lamb one that has taken place on the exchange this week. Are tokens that are locked for data usage or in cards taken into account when balance screenshots are taken?
George Cao: Yes we will take that into account
Q: When will be the private sale tokens be released ?
George Cao: As soon as we mined 90m we will start to release
Q: So let me get this right .. you give us FREE BTC and ltc and even Lambda EVERYDAY if we hold BTMX and agree to share our data
George Cao: Free usdt btc eth
Q: Wow. In a bear market, Free btc is the best thing ever
George Cao: We share revenue with our users, 90% is usdt. Not sure if you like it:)
Q: also consider adding coins like ADA and few from top 30. People need more coins
George Cao: We are adding stellar and zcash soon
Q: I heard they are insured Unless we give password to someone hehe
George Cao: Yes we are using custodian service
Q: George are our funds SAFU with you? Exchange insurance? I would say it is With the industry giants backing this exchange
George Cao: Sequoia matrix bitmain fbg dhvc are our equity investors
Q: What’s to stop People dumping BTMX token after free btc Or stop capital investor dumping on retailer
George Cao: They get it every day. Why would they dump? All equity investors can not sell on secondary market. They can only to reverse mining
Q: Will margin allow reverse mining instead of normal mining?
George Cao: Not initially
Q: People do irrational things when btc moves Or whales dumping, I heard there was a lock up token or something. To stop this
George Cao: We required lock our tokens to get rewards. You can request to unlock at anytime but it takes 24 hours to process
Q: Binance is developing DEX any plans for BitMax ?
George Cao: Not anytime soon we have a looong to do:)
Q: It's good you have dex in mind , with improved scalability in future maybe bitmax can build good dex
George Cao: Agree
Q: Retail investors are important , George knows it haha
George Cao: We care most of retails
Q: It would help if they also burned or locked tokens up
George Cao: Yes we permanently locked
Q: Seems you have everything thought of.. but how about moving to Malta?
George Cao: We priority US. Once us is clear pretty much everywhere is clear
Q: Doesn’t any exchange cover US right now?
George Cao: Coinbase but they have 0 international coverage and 0 client service
Q: What sort of systems are in place for abnormal/suspicious activity on the exchange?
George Cao: We prohibit self trading. For unusual trading behavior we ban the account and as for explain in the first violation. For continued violations we permanently ban the account
Q: can we get a glimpse of mobile application ?
George Cao: There is a beta version you can use but we are keep improving
Q: What are the precautions taken to prevent wash trading ?
George Cao: We have pre trade and post trade checksums. E.g we don’t just scan one account. We check or related account
Q: Will market orders and stop-loss orders be available in the future?
George Cao: Yes we are working on it
Q: what do you think of lambda project and community
George Cao: Lambda is definitely one of the best projects this year. We have been working with lambda for months and have lots of respect ion for the team. Community is also great very well organized. I didn’t talk much but I joined lambda tele group for a while. Great interaction
Q: So the trading starts at 8 pm ETC?
George Cao: It’s postponed. Please stay tuned for announcements
Lambda: We will make announcement giving out time and new date.
Q: when please? It's also more professional to be able to give dates and respect them
Lambda Cao: we are working hard and aiming the date of Dec. 29, pls stay tuned, thank you
George: Unfortunately bitmax and lambda don’t have 100% control of the date and time. Huobi is holding the ball
Lambda: The listing dates have been postponed and we don't want to give out a random date. I request you to have patience and wait for official announcement
Lambda: we will try everything to protect retails interest
Q: Can’t let houbi just arrive late to the party?
Lambda: in the long run we may need Huobi to help us better protect us all
George Cao: We trust lambda team can make the best decision for all investors
Q: Have you been busy with listing recently? Anything else？
George Cao: We have been working 24 hours a day including Chris eve :) Listing and app and margin and lots of new improvements
Q: Why would we need huobi with bitmax on our side.
George Cao: Trust me we are as upset. However as an exchange our mission is to serve projects and investors. Please join us in fully supporting any decision lambda team made. We have 100% confidence in lambda
Q: Are you familiar with the REKTbot and SYSTEM OVERLOAD problems at bitmex
George Cao: Yes but still bitmex is the best place to trade future compare with okex
Q: Slap that Hayes fool when bitmax start margin and futures..
George Cao: Haha i don’t want to declare war with them. Let’s be a bit patient :)
Q: Could bitmax handle That volume and not system overload
George Cao: We are 100% confident
George Cao: Alright i have to run for another meeting. It’s been a great ama. Thanks everyone. For any trading related questions please contact our client support. We promise to get in touch in 5 mins 7/24. Thank you all!

“What is unique about us is that we have actually put theory into practice.”https://preview.redd.it/n6lo2xcmtn621.png?width=800&format=png&auto=webp&s=281acce4b45eed8acf0c52b201d01cb6f0d13507
Wanchain’s Vice President of Business Development, Lini, sat down with blockchain media organization Neutrino for an AMA covering a wide range of topics concerning Wanchain’s development.
The following is an English translation of the original Chinese AMA which was held on December 13th, 2018:
Neutrino: Could you please first share with us a little basic background, what are the basic concepts behind cross chain technology? What are the core problems which are solved with cross-chain? In your opinion, what is the biggest challenge of implementing cross chain to achieve value transfer between different chains?
Lini: Actually, this question is quite big. Let me break it down into three smaller parts:
In China, we like to use the word “cross-chain”, the term “interoperability” is used more frequently in foreign countries. Interoperability is also one of the important technologies identified by Vitalik for the development of a future blockchain ecosystem mentioned in the Ethereum white paper. So cross-chain is basically the concept of interoperability between chains.
In essence, blockchain is a distributed bookkeeping technique, also known as distributed ledger technology. Tokens are the core units of account on each chain, there currently exist many different chains, each with their own token. Of especial importance is the way in which each ledger uses tokens to interact with each other for the purpose of clearing settlements.
Cross chain technology is one of the foundational technological infrastructures that is necessary for the large scale application of blockchain technology.
Neutrino: As we all know, there are many different kinds of cross-chain technologies. Please give us a brief introduction to several popular cross-chain technologies on the market, and the characteristics of each of these technologies。
Lini: Before answering this question, it is very important to share two important concepts with our friends: heterogeneity and homogeneity, and centralization and decentralization.
These two points are especially important for understanding various cross-chain technologies, because there are many different technologies and terminologies, and these are some of the foundational concepts needed for understanding them.
There are also two core challenges which must be overcome to implement cross-chain:
Combining the above two points, we look at the exploration of some solutions in the industry and the design concepts of other cross-chain projects.
First I’d like to discuss the Relay solution.
However the Relay solution must consume a relatively large amount of gas to read the BTC header. Another downside is that, as we all know, Bitcoin’s blocks are relatively slow, so the time to wait for verification will be long, it usually takes about 10 minutes to wait for one block to confirm, and the best practice is to wait for 6 blocks.
The next concept is the idea of Sidechains.
This solution is good, but not all chains contain SPV, a simple verification method. Therefore, there are certain drawbacks. Of course, this two way peg way solves challenge beta very well, that is, the atomicity of the transaction.
These two technical concepts have already been incorporated into a number of existing cross chain projects. Let’s take a look at two of the most influential of these.
The first is Polkadot.
This is just a summary based on Polkadot’s whitepaper and most recent developments. The theoretical design is very good and can solve challenges alpha and beta. Last week, Neutrino organized a meetup with Polkadot, which we attended. In his talk, Gavin’s focus was on governance, he didn’t get into too much technical detail, but Gavin shared some very interesting ideas about chain governance mechanisms! The specific technical details of Polkadot may have to wait until after their main net is online before it can be analyzed.
Next is Cosmos.
Cosmos is a star project who’s basic concept is similar to Polkadot. Cosmos’s approach is based on using a central hub. Both projects both take into account the issue of heterogeneous cross-chain transactions, and both have also taken into account how to solve challenges alpha and beta.
To sum up, each research and project team has done a lot of exploration on the best methods for implementing cross-chain technology, but many are still in the theoretical design stage. Unfortunately, since the main net has not launched yet, it is not possible to have a more detailed understanding of each project’s implementation. A blockchain’s development can be divided into two parts: theoretical design, and engineering implementation. Therefore, we can only wait until after the launch of each project’s main network, and then analyze it in more detail.
Neutrino: As mentioned in the white paper, Wanchain is a general ledger based on Ethereum, with the goal of building a distributed digital asset financial infrastructure. There are a few questions related to this. How do you solve Ethereum’s scaling problem? How does it compare with Ripple, which is aiming to be the standard trading protocol that is common to all major banks around the world? As a basic potential fundamental financial infrastructure, what makes Wanchain stand out?
Lini: This question is actually composed of two small questions. Let me answer the first one first.
The TPS of Ethereum is not high at this stage, which is limited by various factors such as the POW consensus mechanism. However, this point also in part is due to the characteristics of Ethereum’s very distributed and decentralized features. Therefore, in order to improve TPS, Wanchain stated in its whitepaper that it will launch its own POS consensus, thus partially solving the performance issues related to TPS. Wanchain’s POS is completely different from the POS mechanism of Ethereum 2.0 Casper.
Of course, at the same time, we are also paying close attention to many good proposals from the Ethereum community, such as sharding, state channels, side chains, and the Raiden network. Since blockchain exists in the world of open source, we can of course learn from other technological breakthroughs and use our own POS to further improve TPS. If we have some time at the end, I’d love to share some points about Wanchain’s POS mechanism.
Wanchain is focused on different use cases, it is to act as a bridge between different tokens and tokens, and between assets and tokens. For various cross-chain applications it is necessary to consume WAN as a gas fee to pay out to nodes.
So it seems that the purpose Ripple and Wanchain serve are quite different. Of course, there are notary witnesses in the cross-chain mechanism, that is, everyone must trust the middleman. Ripple mainly serves financial clients, banks, so essentially everyone’s trust is already there.
Neutrino: We see that Wanchain uses a multi-party computing and threshold key sharing scheme for joint anchoring, and achieves “minimum cost” for integration through cross-chain communication protocols without changing the original chain mechanism. What are the technical characteristics of multi-party computing and threshold key sharing? How do other chains access Wanchain, what is the cross-chain communication protocol here? What is the cost of “minimum cost?
Lini: The answer to this question is more technical, involving a lot of cryptography, I will try to explain it in a simple way.
In sMPC multiple parties each holding their own piece of private data jointly perform a calculation (for example, calculating a maximum value) and obtain a calculation result. However, in the process, each party involved does not leak any of their respective data. Essentially sMPC calculation can allow for designing a protocol without relying on any trusted third parties, since no individual ever has access to the complete private information.
Secure multiparty computing can be abstractly understood as two parties who each have their own private data, and can calculate the results of a public function without leaking their private data. When the entire calculation is completed, only the calculation results are revealed to both parties, and neither of them knows the data of the other party and the intermediate data of the calculation process. The protocol used for secure multiparty computing is homomorphic encryption + secret sharing + OT (+ commitment scheme + zero knowledge proofs, etc.)
Wanchain’s 21 cross chain Storeman nodes use sMPC to participate in the verification of a transaction without obtaining of a user’s complete private key. Simply put, the user’s private key will have 21 pieces given to 21 anonymous people who each can only get 1/21 part, and can’t complete the whole key.
Wanchain uses the threshold M<=N; N=21; M=16. That is to say, at least 16 Storeman nodes must participate in multi-party calculation to confirm a transaction. Not all 21 Storeman nodes are required to participate. This is a solution to the security problem of managing private keys.
Cross-chain communication protocols refers to the different communication methods used by different chains. This is because heterogeneous cross-chain methods can’t change the mechanism of the original chains. Nakamoto and Vitalik will not modify their main chains because they need BTC and ETH interoperability. Therefore, project teams that can only do cross-chain agreements to create different protocols for each chain to “talk”, or communicate. So the essence of a cross-chain protocol is not a single standard, but a multiple sets of standards. But there is still a shared sMPC and threshold design with the Storeman nodes.
The minimum cost is quite low, as can be shown with Wanchain 3.0’s cross chain implementation. In fact it requires just two smart contracts, one each on Ethereum and Wanchain to connect the two chains. To connect with Bitcoin all that is needed is to write a Bitcoin script. Our implementation guarantees both security and decentralization, while at the same time remaining simple and consuming less computation. The specific Ethereum contract and Bitcoin scripts online can be checked out by anyone interested in learning more.
Neutrino: What kind of consensus mechanism is currently used by Wanchain? In addition, what is the consensus and incentive mechanism for cross-chain transactions, and what is the purpose of doing so? And Wanchain will support cross-chain transactions (such as BTC, ETH) on mainstream public chains, asset cross-chain transactions between the alliance chains, and cross-chain transactions between the public and alliance chains, how can you achieve asset cross-chain security and privacy?
Lini: It is now PPOW (Permissioned Proof of Work), in order to ensure the reliability of the nodes before the cross-chain protocol design is completed, and to prepare to switch to POS (as according to the Whitepaper roadmap). The cross-chain consensus has been mentioned above, with the participation of a small consensus (at least 16 nodes) in a set of 21 Storeman nodes through sMPC and threshold secret sharing.
In addition, the incentive is achieved through two aspects: 1) 100% of the cross chain transaction fee is used to reward the Storeman node; 2) Wanchain has set aside a portion of their total token reserve as an incentive mechanism for encouraging Storeman nodes in case of small cross-chain transaction volume in the beginning.
It can be revealed that Storeman participation is opening gradually and will become completely distributed and decentralized in batches. The first phase of the Storeman node participation and rewards program is to be launched at the end of 2018. It is expected that the selection of participants will be completed within one quarter. Please pay attention to our official announcements this month.
In addition, for public chains, consortium chains, and private chains, asset transfer will also follow the cross-chain mechanism mentioned above, and generally follow the sMPC and threshold integration technology to ensure cross-chain security.
When it comes to privacy, this topic will be bigger. Going back to the Wanchain Whitepaper, we have provided privacy protection on Wanchain mainnet. Simply put, the principle is using ring signatures. The basic idea is that it mixes the original address with many other addresses to ensure privacy. We also use one-time address. In this mechanism a stamp system is used that generates a one-time address from a common address. This has been implemented since our 2.0 release.
But now only the privacy protection of native WAN transactions can be provided. The protection of cross-chain privacy and user experience will also be one of the important tasks for us in 2019.
Neutrino: At present, Wanchain uses Storeman as a cross-chain trading node. Can you introduce the Storeman mechanism and how to protect these nodes?
Lini: Let me one problem from two aspects.
Neutrino: On December 12th, the mainnet of Wanchain 3.0 was launched. Wanchain 3.0 opened cross-chain transactions between Bitcoin, Ethereum and ERC20 (such as MakerDao’s stable currency DAI and MKR). What does this version mean for you and the industry? This upgrade of cross-chain with Bitcoin is the biggest bright spot. So, if now you are able to use Wanchain to make transactions between what is the difference between tokens, then what is the difference between a cross chain platform like Wanchain and cryptocurrency exchanges?
Lini: The release of 3.0 is the industry’s first major network which has crossed ETH and BTC, and it has been very stable so far. As mentioned above, many cross-chain, password-protected theoretical designs are very distinctive, but for engineering implementation, the whether or not it can can be achieved is a big question mark. Therefore, this time Wanchain is the first network launched in the world to achieve this. Users are welcome to test and attack. This also means that Wanchain has connected the two most difficult and most challenging public networks. We are confident we will soon be connecting other well-known public chains.
At the same time of the release of 3.0, we also introduced cross chain integration with other ERC20 tokens in the 2.X version, such as MakerDao’s DAI, MKR, LRC, etc., which also means that more tokens of excellent projects on Ethereum will also gradually be integrated with Wanchain.
Some people will be curious, since Wanchain has crossed so many well-known public chains/projects; how is it different with crypto exchanges? In fact, it is very simple, one centralized; one distributed. Back to the white paper of Nakamoto, is not decentralization the original intention of blockchain? So what Wanchain has to do is essentially to solve the bottom layer of the blockchain, one of the core technical difficulties.
Anyone trying to create a DEX (decentralized exchange); digital lending and other application scenarios can base their application on Wanchain. There is a Wanchain based DEX prototype made by our community members Jeremiah and Harry, which quite amazing. Take a look at this video below.
Neutrino: What are the specific application use cases after the launch of Wanchain 3.0? Most are still exploring small-scale projects. According to your experience, what are the killer blockchain applications of the future? What problems need to be solved during this period? How many years does it take?
Lini: As a cross-chain public chain, we are not biased towards professional developers or ordinary developers, and they are all the same. As mentioned above, we provide a platform as infrastructure, and everyone is free to develop applications on us.
For example, if it is a decentralized exchange, it must be for ordinary users to trade on; if it is some kind of financial derivatives product, it is more likely to be used by finance professionals. As for cross-chain wallets which automatically exchange, I’m not sure if you are talking about distributed exchanges, the wallet will not be “automatic” at first, but you can “automatically” redeem other tokens.
Finally, the remaining WAN tokens are strictly in accordance with the plan laid out in the whitepaper. For example, the POS node reward mentioned above will give 10% of the total amount for reward. At the same time, for the community, there are also rewards for the bounty program. The prototype of the DEX that I just saw is a masterpiece of the overseas community developers, and also received tokens from our incentive program.
Neutrino community member’s question: There are many projects in the market to solve cross-chain problems, such as: Cosmos, Polkadot, what are Wanchain’s advantages and innovations relative to these projects?
Lini: As I mentioned earlier, Cosmos and pPolkadot all proposed very good solutions in theory. Compared with Wanchain, I don’t think that we have created anything particularly unique in our theory. The theoretical basis for our work is cryptography, which is derived from the academic foundation of scholars such as Yao Zhizhi and Silvio Micali. Our main strong point is that we have taken theory and put it into practice..
Actually, the reason why people often question whether a blockchain project can be realized or not is because the whitepapers are often too ambitious. Then when they actually start developing there are constant delays and setbacks. So for us, we focus on completing our very solid and realizable engineering goals. As for other projects, we hope to continue to learn from each other in this space.
Neutrino community member Amos from Huobi Research Institute question: How did you come to decide on 21 storeman nodes?
Lini: As for the nodes we won’t make choices based on quantity alone. The S in the POS actually also includes the time the tokens are staked, so that even if a user is staking less tokens, the amount of time they stake them for will also be used to calculate the award, so that is more fair. We designed the ULS (Unique Leader Selection) algorithm in order to reduce the reliance on the assumption of corruption delay (Cardano’s POS theory). which is used for ensuring fairness to ensure that all participants in the system can have a share of the reward, not only few large token holders.
Wu Di, a member of the Neutrino community: Many big exchanges have already begun to deploy decentralized exchanges. For example, Binance, and it seems that the progress is very fast. Will we be working with these influential exchanges in the future? We we have the opportunity to cooperate with them and broaden our own influence?
Lini: I also have seen some other exchange’s DEX. Going back the original point, distributed cross-chain nodes and centralized ones are completely different. I’m guessing that most exchanges use a centralized cross-chain solution, so it may not be the same as the 21 member Storeman group of Wanchain, but I think that most exchanges will likely be using their own token and exchange system. This is my personal understanding. But then, if you are developing cross chain technology, you will cooperate with many exchanges that want to do a DEX. Not only Binance, but also Huobi, Bithumb, Coinbase… And if there is anyone else who would like to cooperate we welcome them!
Neutrino community member AnneJiang from Maker: Dai as the first stable chain of Wanchain will open a direct trading channel between Dai and BTC. In relation to the Dai integration, has any new progress has been made on Wanchain so far?
Lini: DAI’s stable currency has already been integrated on Wanchain. I just saw it yesterday, let me give you a picture. It’s on the current 3.0 browser, https://www.wanscan.org/, you can take a look at it yourself.
This means that users with DAI are now free to trade for BTC, or ETH or some erc20 tokens. There is also a link to the Chainlink, and LRC is Loopring, so basically there are quite a few excellent project tokens. You may use the Wanchain to trade yourself, but since the DEX is not currently open, currently you can only trade with friends you know.
