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.

Dragonchain FoundationThe Dragonchain Foundation was created on January 17, 2017. https://den.social/l/Dragonchain/24130078352e485d96d2125082151cf0/dragonchain-and-disney/
With the development of blockchain technology, obtaining data on the chain only is no longer satisfying and how to bridge the real world and the blockchain world has always been the direction of the technological breakthrough. Under this background, Oracle Machine came to our attention. In particular, with the popularity of the DeFi concept, the industry starts to witness a boom of the application of Oracle Machine in financial derivatives, trading platforms, gambling games, and prediction markets.submitted by ThemisOracle to u/ThemisOracle [link] [comments]
At present, Oracle Machine represented by Themis is developing fast with a good momentum, leading the trend of the development of Oracle Machine and continuing to consolidate the basic technical support for the DeFi revolution. Themis’ mining system has been launched in the market, which is refreshing and appealing (see https://themisoracle.com/#/credit for details on the Themis mining).
90% of MIS, the native token of Themis, will be used for mining output. The entire mining mechanism runs through a distributed oracle protocol, which sets up three roles: data provider, data validator, and arbitration node. Reward and punishment mechanisms are applied to ensure the smooth ecological operation.
How does Themis mining work? Is it a new way to become wealthy? What are the characteristics? To answer these questions, we need to analyse the distribution mechanism, mining mechanism, and token value of Themis.
With a fairer mining mechanism, small and medium-sized miners can enjoy better benefits
One of the core values of blockchain is fairness and justice, and allowing everyone in the network to play a role in the system without permission. However, Bitcoin mining is now monopolized by several mining machine vendors such as Bitmain, leaving little space for other miners to participate. If those old PoW public chains, such as Bitcoin, has formed the head effect in mining, what about those new projects? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked top with the strong financial strength and user base of the top exchange, making the small and medium nodes hard to participate.
After comparison, we can find that the mining mechanism of MIS is very friendly to ordinary users. Assuming that there are 12 mining transactions in a block, the ranking according to the MIS pledged by each transaction would be as follow:
The pledge ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user pledge amount, which can prevent MIS from being controlled by a small number of people, avoid monopoly, creating a win-win situation in the Themis community.
Compared with other mining projects, Themis has introduced a unique pledge ranking method in the mining design. Users in the best ranking area will get the most benefits, which is a good mechanism guarantee for attracting more users to participate in mining. At the same time, it can lead to the decentralization of data providers, ensuring the decentralization of the oracle system and the positive development of the community.
How can miners join in Themis mining? The answer is to become a part of the ecology by playing the role of either data provider, data validator, or arbitration node.
The data provider is mainly responsible for providing various types of data, and the data validator verifies and challenges the data offered by the data provider and provides new data. The arbitration node arbitrates the query raised by the data validator and come up with the final result.
Both the data providers and validators of Themis need to pledge MIS to obtain the qualifications, and the caller of external data also needs to pay MIS assets when accessing the data of Themis oracles. If the data has been verified as correct, data providers and validators will receive mining rewards, and the more they pledge, the more rewards they will receive.
In the mining design of Themis, miners can acquire MIS by providing verifiable random number or offering the price of in-chain assets. Whenever miners call mining contracts, the system will charge no service fee (excluding the service fee of ETH). In addition, if no mining transaction occurs within a certain period of time, the first newly-emerging block containing mining transactions will acquire all the MIS rewards. In this way, miners can be encouraged to continue mining and maintain the ecological stability of Themis.
The number of MIS mining for each mining transaction of miners is calculated as follows:
First, calculate the number of MIS mining rewards N contained in the block of the packaged mining transaction. If the height difference between the block and the previous block containing the mining transaction is y, then N = y * 20.
The MIS mining quantity of this mining transaction is M, then M=Xi/(📷)×N. Among them, X is the ranking of the MIS pledge amount in the block, and those who pledge the same amount of MIS have the same ranking.
Few official pre-mining, while 90% belongs to the community
Based on the official announcement, the distribution of MIS is:
The total amount of MIS is 1 billion, 10% is reserved for early project promotion, the remaining 90% are produced by mining, in which 75% are directly awarded to data providers, 10% to developers, and 5% as reward for arbitration nodes and ecological incentive. The production of mining will be progressively decreased and released with ETH. For some current popular VC-invested projects, institutional holdings hold more than half of blocks and unlock the block every month, which is a huge stress for ordinary pledge users. Many projects also went wrong because institutional investors do not abide by the rules. For MIS, because there is fewer official pre-mining, the selling pressure will be smaller, which is more in line with the value of the blockchain.
The release plan of developer and arbitration node and ecological incentive is as follows:
The release plan of data provider incentive is as follows:
The MIS awarded per block reduces by 10% in every 4 million blocks, and the reward per block at present is 20 MIS.
We can see that the allocation of MIS follows the following principles.
First of all, as MIS is the platform certificate of Themis, it is very reasonable to reserve 10% of MIS for early project promotion.
Secondly, 90% of MIS is produced through sustainable mining. This proportion can motivate contract users and miners to conduct contract mining, truly implementing the spirit of win-win community and token economy.
Finally, among the 90% of MIS, better incentive mechanisms have been adapted, mining reward ratios are subdivided, which can attract more investors to participate in mining.
Reasonable mining mechanism highlights the project value of Themis
Themis, as a public chain that provides a mechanism to solve the problems in Oracle Machine, has a unique charm in the value of MIS.
From the perspective of the number of tokens, the total amount of MIS is 1 billion, and the total mining pool is 900 million. 90% of the tokens are generated by mining, and the mining output gradually decreases its release with the Ethereum block, showing a great potential in its future added value. The earlier you participate in mining, the more profit you can gain.
From the perspective of Themis’s ecological design, Themis is committed to the original intention of building a price oracle. The data provider pays on-chain fees and pledges a certain amount of MIS, and determines the income obtained according to the scale of the pledge; the validator can make profit from challenging the data. Also, any smart contract developer or user need to pay the corresponding fee when calling Themis, and this part of the profit will be distributed to the data provider in proportion. Through this design, a logical closed loop is completed to ensure the healthy operation of the entire ecology and achieve the goal of mutual benefit. In Themis, all parties in the ecology can work together to grow more wealth.
In all, MIS has a huge potential for future development and arbitrage, and of course, a great profit potential as well.
Today, public chains like Themis are not just a technology platform, but also a symbol of future economic operation mode which connect between the blockchain and the real world. Themis, with a fair, justice and open network through mining, is building a strong token ecology, connecting external chain data and the systems, realising data interaction between blockchain and the real world, and more importantly, creating a new mode of token economy.

How popular is DeFi?
Link, known as the leader of the oracle machine, has increased by 305.19% for the past three months, with an investment return of 17,052%, climbing to the fifth spot in the cryptocurrency ranking list by market value in the short term;
Since its issuance, YFI, which has soared 350 times all the way, has attracted 630 million US dollars of investment in 5 days, and was even dubbed the next Bitcoin in this circle;
From Comp for lending, KNC and BAL, governance tokens for decentralized exchanges, to SNX which is a stable currency payment network, various governance tokens of the DeFi ecosystem have emerged in an endless stream, stirring the blood in the market.
Such a boom is not only reflected in the currency price, but also pushes the brand new DEX based on the AMM (automated market making) model an overnight hit. UniSwap, known as the next-generation casino, has surpassed the world's first-tier centralized exchanges such as Binance, OKex, and Huobi in user activity, daily trading volume, and daily turnover.
With the rapid rise of UniSwap, the DEX threat theory has once again triggered heated discussions among the media and communities in the blockchain industry.
DEX on the Rise
The success of UniSwap is by no means something accidental. As early as 2018 when centralized exchanges suffered the hacker theft one after another, Vitalik Buterin, founder of Ethereum, predicted that the future lay in decentralized exchanges and that Ethereum, by developing a "better" decentralized platform, could empower the cryptocurrency community to regain the dominance from the centralized cryptocurrency exchange.
To realize the decentralized concept of returning to users their asset ownership, geeks in the blockchain industry have made many attempts.
Kyber Network, Bancor, Balancer, 0X, Curvefi, etc. are all DEXs based on Ethereum blocks. For a long time, affected by the performance of Ethereum and cross-chain issues, these DEXs were once stagnant.
With the lessons learned from Ethereum DEX, newcomers to the DEX have focused on high performance, high TPS, and rich assets as the ultimate goal for product development.
Amid the DEX threat theory, major exchanges have deployed their own public chain DEX products in a response to their respective development strategies: Binance launched Binance DEX on its Binance Chain, and Bittrex Exchange unveiled Ethfinex on the Ethereum and EOSfinex on the EOS blockchain, two platforms where users can exchange for fiat currencies; last year, CoinEx officially launched CoinEx Chain, a public chain dedicated to decentralized transactions, followed by CoinEx DEX.
Since the birth of the DEX in the blockchain world, this field has never run out of competition.
By independent development or other’s advantage?
From 2017 when it was established to 2019 as it stabilized, DEX has witnessed its annual trading volume skyrocketing from less than US$5 million to over US$2.5 billion. As DeFi gains fame and grows rapidly, DEX has grown into the most popular source of money, attracting a flood of speculators. In the past month, the trading volume of the global cryptocurrency market DEX has exceeded US$ 4 billion, more than twice the figure across 2019.
In the past two years, despite the increasingly in-depth exploration in the DEX, the cross-chain issue remains a stumbling block in its development path. DEX will not outperform CEX in the trading experience until a cross-chain solution is worked out.
The concept of DeFi went viral in 2019. With the continuous improvement of the DeFi ecosystem, the current Ethereum blockchain has developed into a complete decentralized financial system, covering mortgage lending, interest from deposit, leveraged trading, token exchange, identity authentication, and other infrastructure essential to traditional financial systems.
In addition to the mouth-watering profit, the DeFi ecosystem has also brought along explosive growth in both the type and quantity of digital assets, making DEX a market favorite. Compared with the DEX dedicated to public chains, the Ethereum-based DEX has been equipped with more possible functions and thus become more attractive thanks to the comprehensive supplementary infrastructure on Ethereum.
This also presents DEX pioneers with new opportunities. Dubbed “Swap’s summer”, the summer of 2020 has seen a market rush in Swap development after UniSwap became a hit.
Miniswap, Justswap, and btswap are no more innovative than UniSwap according to their product structures and white papers.
By comparison, OneSwap has injected unique essence into its product design and governance model based on UniSwap's automated market making.
OneSwap, which has a double mining model + order book, has received an investment of tens of millions from CoinEx even before the product is launched. It is known that OneSwap is jointly developed by a group of technology geeks who have engaged in the cryptocurrency community for many years. The project was initiated by a member of the team in an attempt to upgrade UniSwap after he experienced the convenient AMM enabled by UniSwap.
Without limit orders, users have to trade in the price set by the platform, which, however, compromised their experience. In addition, the lack of liquidity mining and transaction mining rewards cannot reduce the losses of liquidity providers caused by unilateral market conditions.
"DEX still has much room for perfection, and could even surpass CEX in trading experience"
The OneSwap development team always believes that UniSwap still has a long way to go before it becomes the strongest DEX in the DeFi ecosystem. They have endeavored to, relying on their abundant experience in exchange product development and digital currency trading, create the most powerful DEX product in the DeFi ecosystem based on smart contracts.
OneSwap is called the “upgraded UniSwap” in the community. By the combination of the Constant Product Market Maker (CPMM) model in the Uniswap project and the on-chain order book, it reduces restrictions on users’ trading, and, through its OneSwap Wallet, improves user interaction methods and further enhances their experience in trading and product usage.
OneSwap boasts one-click token issuance and listing essential to DEX. Unlike the listing review mechanism on Binance DEX, the setting of OneSwap is more consistent with the concept of decentralization. Anyone can put his or her good projects and ideas, if any, into practice through OneSwap without permission.
In terms of product design, OneSwap will add to its function menu the Candlestick chart, order form, and depth chart according to user habits, apart from limit orders. These functions will offer OneSwap users an experience as smooth, easy-to-use, and convenient as in the CEX.
A new source of money? A two-pronged platform with transaction mining + liquidity mining
To support on-chain governance, OneSwap will issue a ERC20 governance token called ONES. The total number of ONES remains constant at 100 million, 50% of which will be used as community funds to support the construction of the OneSwap ecosystem and 50% will be owned by the OneSwap team. Community funds can be applied for through on-chain governance. 5% of the part held by the team will be unlocked initially, and the rest will be unlocked at a rate of 5% every six months until all is unlocked after four and a half years.
After the OneSwap product was launched, the OneSwap team will take part of the initially unlocked tokens as airdrop rewards for the open beta. Then OneSwap will officially start liquidity mining and transaction mining, and the governance token ONES will also be simultaneously launched on centralized trading platforms across the world. The first round of mining activities will last for one month, and mining rewards are yet to be made public.
Liquidity mining is a popular way of obtaining governance tokens in the DeFi ecosystem. Well-known DeFi projects including COMP, Cure, and Banner have all enabled liquid mining.
Transaction mining could date back to 2018 when Fcoin grew popular.
The transaction mining model initiated by Fcoin in 2018 once set off a bull market that year, pushing many investors into financial freedom in the rush of transaction mining. In addition, transaction mining based on the DeFi ecosystem is still a blue ocean, which is not common in the current market. The success of OneSwap's double mining model, if possible, would surely start a craze in the cryptocurrency market.
The OneSwap team has not yet announced specific mining rules, but disclosed that it has developed the smart contract code. To ensure the product security, OneSwap will invite three well-known security agencies in the blockchain industry to audit the code and announce the auditing results in early September at the soonest.
DeFi did not rise to fame without reason in 2020. Such overnight popularity is an inevitable result of Ethereum's efforts to build a decentralized consensus mechanism and improve infrastructure in the past few years. Ethereum has almost become the only public chain in the DeFi circle and the only construction base for well-known DEX. If OneSwap succeeds, it means a huge breakthrough for both DeFi and Ethereum, and decentralization in its true sense is around the corner.
Bitcoin options are breaking records, and exchanges are competing for this segment. We will tell you what these tools are and how they worksubmitted by Smart_Smell to Robopay [link] [comments]
The cryptocurrency market is constantly evolving, integrating with the traditional and inheriting complex financial products such as futures and options.
Some types of fixed-term contracts are already firmly established in the bitcoin industry. This is noticeable by the activity of traders on the CME.
However, the situation with options is somewhat different. These derivatives are difficult to understand among ordinary market participants and are not yet so popular.
Nevertheless, there is a demand for such tools, as evidenced by the growth dynamics of this market segment and interest from platforms such as Binance and Bitfinex.
Bitcoin options have already been offered on CME, LedgerX and Bakkt, which are regulated and oriented primarily on whales. Among the unregulated sites, the leader is Deribit, followed by FTX and OKEx.
ForkLog magazine figured out what options are and what types of options are. We will talk about the features of these tools and the current state of affairs in the segment. In this article you will also find comments by leading market experts on the role of options in the industry.
What are options and how do they work?An option is a financial contract concluded between two parties — the holder and the seller. The first receives the right, but not the obligation, to buy or sell a certain amount of the underlying asset at the strike price (strike price) on a specific date (expiration date).
The seller undertakes to buy or sell the asset at the request of the option holder. The latter pays the seller at the time of purchase of the contract a certain amount of money — the so-called premium.
The rights and obligations of the holder and seller differ significantly. The former has the right to choose whether to exercise the option or not. The seller is obliged to fulfill the terms of the contract at the request of the holder.
Parameters such as the type of underlying asset, expiration date, strike price are fixed at the time of issue of the contract, after which they cannot be changed.
Like futures, options are derivative financial instruments and derivatives. This means that they can be based on various underlying assets (BA) — stocks, indices or cryptocurrencies.
“Like the options already existing in traditional finance for all major assets, there are contracts based on BTC and ETH on the cryptocurrency market. They are very interesting financial products“, said Su Zhu, head of Three Arrows Capital, in a conversation with ForkLog.
Options are used both for hedging risks and for speculative trading. For example, a speculator confident in the growth of the underlying asset buys a call option. If the BA price rises above the strike, the trader can use his contract to buy a discounted asset.
“Derivatives such as options allow users to hedge risks and generate revenue. Derivatives play a key role in the traditional financial market. These tools are needed so that the cryptocurrency market continues to grow and develop, being filled with new participants“, said Aaron Gong, vice president of Binance Futures.
Practical use of optionsConsider the simplest example of options hedging. Suppose there is a company manufacturing tomato paste, sauces and ketchups. There is a farmer supplying this company with tomatoes. He acts in conditions of fierce competition, close to perfect.
It is extremely important for a company to buy raw materials cheaper to minimize production costs and remain profitable. The farmer, in turn, hopes for a long-term cooperation with the company so as not to lose a major client.
The company offers the farmer an option, assuming the right to buy 10 tons of tomatoes of the next year’s crop at the current price — say, $1,000 per ton. To exercise this right, the company pays the farmer an option premium of 3% of the total transaction amount of $10,000, that is, $300.
The farmer will have to, at the request of the company, sell the appropriate quantity of goods at the above price and at a specified time.
A year later, the crop was high, which led to a decrease in the market value of tomatoes to $800 per ton. The company decides not to exercise its right to purchase raw materials for $10,000, as other farmers can buy the same 10 tons of tomatoes for only $8,000.
Thus, having lost only $300 as a premium on an option, the company is insured against price risk. Buying raw materials at a significantly lower market price is more than worth the price of the option contract.
Let’s imagine another scenario: the crop turned out to be unimportant and the price of scarce tomatoes jumped to $1200 per ton. Then the company will certainly take advantage of the right to purchase tomatoes for $1000. Thus, the result is any case.
It is easy to guess that the options can be used by miners to hedge the risks of adverse changes in the price of the extracted asset. For example, expecting a decrease in the price of BTC, miners can use options that give them the right to sell cryptocurrency in the future at a price higher than the breakeven point.
“Miners are already very active in options markets. And, probably, they will remain active“, Su Zhu said.
Su Zhu is confident that in the long term, options will make the cryptocurrency spot market more liquid and attractive to a wide range of participants. He added that the growing popularity of such contracts among miners could significantly reduce sales pressure.
“Options give miners the opportunity to fix the price of coins mined in the future. Miners can better manage their production costs and protect themselves from market volatility“, said Aaron Gong, expressing confidence that the popularity of options will continue to grow.
According to him, such tools open up new opportunities and may be of interest to speculators, funds and long-term cryptocurrency holders.
“Institutional investors are also showing growing interest in options and other derivatives. Last week it was reported that the famous Wall Street trader Paul Tudor Jones allocated a few percent from his Tudor BVI fund for bitcoin futures. This is a positive signal, which means that more and more institutions are interested in the cryptocurrency market“, Gong added.
However, option strategies are not suitable for every market participant — effective work with these tools requires certain experience, Co-founder of CoinIndex.agency Julia Sporysh is sure:
“Of course, in order to use this effectively, the miner must have an experienced trader (option strategies are some of the most difficult on the market) — or they will have to unite and work through specialized trading companies. This market exists, although it is not for the general public.”
Also, according to her, options may be of interest to funds and retail traders who have gained a hand in speculative trading.
“Options are an independent and good speculative tool. And if you have positions in futures or in the spot market, it’s just the time to explore new opportunities“, added Yulia Sporysh.
Types of optionsThere are two main types of options — option call and option put. The first gives the right to the contract holder to purchase a certain amount of the underlying asset from the seller (they also say — the inscription) at the strike price on a certain date in the future. This type of option was used in the tomato example.
The put option, on the contrary, gives the buyer of the contract the right to sell the underlying asset at a fixed price. The latter may be higher than the market at the time of expiration, which is beneficial to the trader.
Market participants use the call, predicting an increase in the price of BA, and put — expecting it to decline.
More complex strategies use combinations of these two types of contracts.
There is also the term “covered option”. For example, an option call is covered if the seller has the amount of the underlying asset corresponding to the terms of the contract.
Options may also differ in the style of execution — American or European.
European-style options require the holder to execute the contract exclusively on the expiration date. Such options, in particular, are presented at CME and Bakkt.
American style implies the possibility of contract execution at any time prior to the date of expiration. Options of both styles are traded all over the world, their names have no relation to geographic location.
There are less standardized, exotic options. However, the popularity and importance of such instruments in the financial market is not so great.
Parameters and conditions for trading certain options are described in the specifications for them, which indicate the expiration date, strike price and other elements of the contract.
Premium, strike price and cash optionThe option premium is the amount of money paid by the buyer to the seller. The premium is equal to the value of the contract and, in fact, represents a fee for the risk of adverse changes in the value of the underlying asset.
The option premium is formed by two components:
• Intrinsic value — the amount that the buyer would receive if the contract were currently executed. It depends on the ratio of the price of the underlying asset and the strike.
• Time value — depends on the time remaining until expiration. Usually, the less time it takes to execute a contract, the lower the premium.
As a rule, high price volatility contributes to premium growth, and vice versa. A deal with a close strike price in relation to the current one has much greater chances of closing in profit and, therefore, the premium for such an option will be relatively high.
The strike price is the price fixed in the option at which the buyer of the call option can buy (or sell, if this is a put option) the underlying asset. In turn, the seller of the contract is obliged to sell or buy BA.
Money is an indicator of the ability to receive funds from the exercise of the right to exercise a derivative. In the context of options, cash can be calculated by comparing the spot price of the BA and the strike price of the option. Thus, three options are possible:
• “in the money” option: in the case of a call — if the spot price is higher than the strike (then the intrinsic value of the contract is positive), in the case of a put, on the contrary, if the BA price is lower than the strike;
• option “on money” (or “with one’s own”) — equal strike to current stock quotes, intrinsic value equal to 0;
• the option “out of money” (“without money”) — the exercise of the option is not economically feasible; in such a situation, the current price of the underlying asset is lower than the strike price of the call option or, conversely, the spot price of the BA is higher than the strike price in the case of a put.
Option strategiesThere are many option trading strategies. Four basic approaches can be distinguished.
Long call — buying a call option, the investor expects an increase in the price of the underlying asset above the strike on the expiration date of the contract. Then he will be able to buy an asset at a discount to the market price and thus earn on the difference. If the price drops below the strike, the buyer risks only the premium paid for the option.
Long put — is a kind of alternative to a short position in the spot market. The buyer of the put option hopes to make money, assuming that the price of the BA falls below the strike at the time of expiration. In this scenario, the investor may sell the asset at a higher price than the market price.
Also, through a put option, an investor can limit the risk of a fall in the price of an asset that has a long position open. According to Su Zhu, miners may use the “protective put” strategy, in whose activity a substantial and prolonged drop in the price of mined cryptocurrency is undesirable. Through such tools, miners can provide profitable or even break-even activity.
Short call — the investor acts as the seller of the contract, counting on a decrease in the price of BA below the strike on the date of expiration. However, the higher the price of the asset, the more losses the inscription bears. Thus, the risk of the seller of the contract is unlimited, and the profit potential is limited by the premium on the sale of the call.
Short put — the seller of such an option expects a premium on it, being firmly convinced that the price of the BA will be higher than the strike.
Combinations of these basic strategies may underlie more sophisticated options trading approaches, such as:
• protective put — purchase of a put option for an available asset;
• covered (secured) call — an investor sells a call option to an existing BA or which will be acquired simultaneously with the sale of the option; the strategy reduces the risk of owning an asset, since a fall in its price is partially offset by a premium;
• straddle — a kind of bet on volatility, which implies the purchase of a call and put option on the same asset with the same expiration date and the same strike price;
• strangle — almost the same as straddle, differs only in different strike prices.
ConclusionsOptions are complex financial instruments, their mechanism of work is unlikely to be mastered immediately by most novice traders. Nevertheless, these derivatives may seem interesting to experienced market participants and, in particular, to miners.
The following advantages and disadvantages of options can be distinguished. Of the advantages of these contracts, we note:
- flexibility of use in speculative trading;
- the ability to use many combinations and trading strategies;
- a good tool for hedging risks;
- the ability to use in any trend — upward, downward, sideways.
- the difficulty of understanding the mechanism of work, especially for novice market participants;
- asymmetric conditions and, accordingly, risks for the buyer and seller;
- the complexity of trading strategies;
- the volatility of an option premium, which depends on the proximity of the expiration date and price dynamics in the spot market;
- low liquidity.
Different industry players have different cryptocurrency options. Some consider them promising tools useful for miners, funds, retail traders and the market as a whole. Others are convinced that such derivatives are archaism.
Nevertheless, options are gradually taking root in the cryptocurrency market. This is evident in the dynamics of trading volume and open interest. In addition, more and more exchanges are trying to add support for these contracts, which contributes to increased competition and further development of the industry.
