Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

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

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

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

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Interview With Eddie Jiang: How CoinEx Is Adapting To The Exchange Space And Growing

Interview With Eddie Jiang: How CoinEx Is Adapting To The Exchange Space And Growing
Written by chaintalk.tv
https://preview.redd.it/v238540taz751.jpg?width=1280&format=pjpg&auto=webp&s=2a852e171a74e49da802d7c12fadba452cf4cf43
We recently had the opportunity to interview the VP of ViaBTC Group, Eddie Jiang. ViaBTC Group owns popular crypto exchange CoinEx and ViaBTC Pool. In this interview Eddie discusses being the first exchange to use BCH as the base currency, ViaBTC Pool and integrating with CoinEx, new features and ambassador program, and competing with other exchanges like Binance and Huobi. Please enjoy the interview below.
How come you decided to open up CoinEx to other cryptos other than just BCH?
Eddie Jiang: CoinEx is the world’s first exchange to implement Bitcoin Cash as a base currency. At that time, it was evident that there was a demand for BCH trading markets, and we are the first to explore this opportunity. It also shows our determination to support the BCH’s development.
As CoinEx is developing, our goal becomes bigger and we are aiming at the global market. We need to constantly improve our product diversification to meet the different needs of more users, so we open up to other cryptos. In the past six months, we have listed more than 50 new tokens. Up to now, we have listed 129 cryptos and 313 markets. Besides, in addition to spot trading, CoinEx also supports perpetual contract and other derivatives trading.
How does CoinEx integrate with the ViaBTC Pool?
Eddie Jiang: ViaBTC Group announced a strategic upgrade, which included a new organizational structure, product innovations and service improvements, on 30 May.
As part of the change, the Group has established three dedicated business units (BU): the financial services BU, consisting of ViaBTC mining pool and CoinEx exchange; the infrastructure services BU, including ViaWallet and Blockchain Explorer; and the ecological development BU, focusing on the research and development of public chain technology and the construction of the ecology.
After halving, the combination of mining and finance will become closer and closer. Investing in mining machines is like buying a Bitcoin option. Miners need more flexible financial products to maintain and increase the value of assets, or hedging services. Based on this judgment, the operations of ViaBTC mining pool and CoinEx exchange will be integrated in the future to realize the financial empowerment of the mining pool to meet the diverse financial needs of miners.
Features of this integrated product upgrade can be summarized as: “ The mining pool is the wallet, and the wallet is the transaction.” ViaBTC is the world first mining pool that has a wallet embedded in the mining pool account. Users do not need to transfer the mined coins, and can realize the function of coin exchange within the wallet. For example, they can directly convert the mined coins into USDT to pay electricity bill. What’s more, users can store, deposit and withdraw their revenue, and transfer assets to CoinEx at any time without charge, as well as complete other operations on the exchange, such as purchasing wealth management products for asset preservation and appreciation. In addition, we also provide hedging services. All of the above functions can be completed in one stop in the mining pool, without the need to transfer assets between different platforms.
The exchange empowers the mining pool, and the mining pool will further bring more traffic and resources to the exchange. The two complement each other and development coordinately.
CoinEx has recently added many new features. Can you talk about what new updates were made to the platform and why you made them?
Eddie Jiang: We have always attached great importance to the development of overseas markets since our establishment, and one of our major goals this year is to cover at least 10 different languages speaking markets.
To realize this and to meet the needs of more users worldwide, CoinEx has been continuously optimizing and upgrading its operating strategies, products and services. Our product diversifications are constantly improving. As I said before, we have launched leverage trading, perpetual contract trading, and wealth management products in addition to just spot trading. However, we don’t ignore the importance of spot trading. More mainstream, popular, and high-quality tokens have been listed, and up to now, there are 129 tokens and 313 trading pairs on CoinEx.
During the epidemic, we have never slowed down our development. Lacking of the OTC service has always been a shortage for CoinEx. In March, we partner with Simplex to integrate the first fiat onramp to our platform. People now can buy crypto with their credit cards, which lowers the threshold for more people to enter the crypto world. Moreover, we announced global strategic partnership with Matrixport to provide people with large amount of fiat to crypto needs the OTC service. These newly launched services also help to attract more users.
At the same time, CoinEx has been launched in Arabic, Italian, English, Japanese, Russian, Korean and other 16 languages. Earlier we also carried out product upgrades, making the UI and function sections clearer.
In terms of operations, we launched an upgraded CoinEx Ambassador program in March. To best utilize each ambassador’s personal strengths, there are four categories of CoinEx Ambassador with different responsibilities, namely Referral Ambassador, Marketing Ambassador, Operation Ambassador, and Business Ambassador, which will expand our brand’s exposure and help CoinEx grow into a more international exchange platform.
From March until now CoinEx has seen a 100% increase in user registrations. Why is that and are you able to see where they are coming from?
Eddie Jiang: Because of the efforts mentioned above, in 2020, we’ve seen an exponential increase in activity in just the past few months alone. In this year alone, CoinEx’s daily registered users increased by 100%. These new users mainly come from markets such as the Middle East, Asia Pacific, and more.
Interestingly, we saw an uptick in traffic from the Middle East in March. User growth in Southeast Asia also picked up significantly, newly registered users increased by 133.6% in April.
With Binance, BitMex, Huobi, Bybit, and Deribit, controlling most of the crypto futures and options markets, where do you see CoinEx fitting in? How do you plan to capture market share from these large exchanges?
Eddie Jiang: We won’t compete with others. We focus on ourselves to improve products and our goal is to be better than yesterday.
Our pace is solid and steady, instead of focusing on temporary heat and flow. We have always attached great importance of spot trading, and we are committed to be responsible for users’ investment. We have set up CoinEx Institution, which is dedicated on project research. A listing committee consist of core team members review and vote on projects recommended by the CoinEx Institution. In this way, fraud projects are avoided as much as possible.
Besides, we will focus on niche areas with great potential. For example, Southeast Asia and the Middle East. CoinEx can serve users in those countries well by providing a platform with rich cryptos to trade, and will pay more efforts on refined operations in different countries.
Moreover, CoinEx has a very complete ecosystem. Financial services, infrastructure, and ecological development, the three business units complement each other. The infrastructure BU is our cornerstone and is positioned as a defensive product; the financial service BU is a cash cow and is positioned as an aggressive product; the ecological development BU focuses on the public chain ecology and is the future infrastructure.
What is the geographical breakdown of the CoinEx userbase?
Eddie Jiang: The current proportion of CoinEx’s overseas users has reached 80% of the total registered users, and mainly in Australia, Southeast Asia, North America, Middle East and South Korea.
Do you have plans to focus on any certain jurisdictions? How will you do that?
Eddie Jiang: When we evaluate regions, two things matter: policy and potential.
Whether an exchange’s business expansion in a region is smooth or not largely depends on the region’s policies. If the region is not very friendly towards cryptocurrency or has repeated attitudes, there will be more difficulties and the cost will be much higher.
For a region’s development potential, we need to think about the demand and market development status. South Korea, Southeast Asia, the Middle East and other regions are all areas with good potential for cryptocurrency development. Compared with Europe and America, policy risks in these countries are lower, and the supervision mechanism is relatively complete. The public has a high degree of awareness of cryptocurrencies. Besides, some regions or countries have inflation problems due to political and economic reasons.
CoinEx will continue to focus on the Middle East and South Asia, which are relatively niche. India has just lifted ban on cryptocurrency trading this year, and there are many cryptocurrency investors in Indian. CoinEx can serve them well by providing a platform with rich cryptos to trade. More people in the Middle East are interested cryptos, especially in countries that are subject to economic sanctions or high inflation. For those people, cryptocurrencies are one of the best choices for asset preservation.
Since the CoinEx Ambassador program launched in March, it has been almost three months. We are conducting the second round of ambassador recruitment. This time, we will use the power of ambassadors to expand our recruitment coverage and strive to attract more crypto enthusiasts from all over the world to grow together with CoinEx. Moreover, we will launch the National Expansion plan and leverage on the CoinEx and ViaBTC mining pool resources, to further explore the Russian market. At the market level, we will make more PR efforts in local markets, and start refined operations.
What is CoinEx Chain and CoinEx DEX?
Eddie Jiang: CoinEx Chain is a public chain built on the Tendermint consensus protocol and the Cosmos SDK. It consists of three dedicated public chains parallel to each other. Among these three chains, CoinEx DEX meets the most basic needs of DeFi for token issuance, transfer, and transactions. The Smart Chain is designed to meet the needs of complex financial scenarios and delivers programmable cash. The Privacy Chain facilitates privacy and security.
On November 11, 2019, we took the lead in launching the Mainnet of CoinEx DEX. CoinEx DEX is the world’s first public chain dedicated to decentralized transactions. Users can easily manage their digital assets on it.
CoinEx DEX can fully satisfy the following conditions: users have private keys at their own disposal; transfers and transactions are all completed on-chain, which is 200% transparent and checkable; the issuance, transfer, and transaction of tokens do not require review or permission; the community governance and operation is decentralized, similar to EOS, and validators are introduced to the community ecosystem construction and governance. There are currently 41 validators.
It also has extreme performance. TPS reaches as high as 10,000 and transactions are confirmed within seconds. The transaction fee, 0.0001 US dollars for each transaction, is negligible.
Third, it’s simple and easy to use. The new operation interface design helps beginners get started quickly; with the one-click token issuing module, users only need to fill in a few items to issue tokens; the built-in automated market-making module guarantees liquidity.
How will CoinEx DEX improve the decentralized exchange space that has been unable to gain much adoption?
Eddie Jiang: There are many challenges and difficulties facing centralized exchanges. The first difficulty is security. Security is a huge concern for CEXs. Over the last 10 years, hackers have stolen more than $1.5 billion from centralized exchanges. In fact, research groups estimate that hackers stole somewhere between $950 Million and $1 Billion from centralized exchanges in 2018 alone. There were also incidents of coin thefts in other exchanges in 2019. Many exchanges, such as Mt. Gox, Youbit, were forced to file for bankruptcy and shut down as a result of hacks.
The second is high management costs. Centralized exchanges need to list a large number of cryptocurrencies and each of them have different trading pairs. That entails huge efforts in development and maintenance and, thus, high management costs.
The last is global policies. Cryptocurrency is faced with different regulatory policies in different countries. Every time a centralized exchange enters a country, it needs to adapt itself to local regulatory policies for compliance. This is a holdback for the exchange’s rapid market expansion globally. Such adaptation will also bring a huge learning cost for the exchange team.
Obviously, these problems can be well solved by DEX. CoinEx DEX is a true DEX with full open source and full community governance, as well as without depending on official nodes, websites, wallets, etc. On DEX, users are able to in charge of their own private keys and assets all by themselves. Their assets are more safe and secure. Transfers and transactions are all completed on-chain, which is 200% transparent and checkable; and the issuance, transfer, and transaction of tokens do not require review or permission. What’s more, CoinEx DEX provides a great and convenient user experience.
How will CoinEx Chain and DEX help the crypto industry as a whole?
Eddie Jiang: The public chain is the cornerstone of the blockchain industry. CoinEx Chain has the parallelism of multiple dedicated public chains, each of which performs its own functions, by cross-chaining for both high performance and flexibility.
CoinEx Chain is committed to building the next generation of blockchain financial infrastructure. It is a more complete ecosystem built around the DEX public chain. The DEX public chain is a dedicated public chain developed specifically for token issuance and trading and the biggest improvement on trading speed, so it only supports the necessary functions, not smart contracts.
But smart contracts are the foundation for building more complex financial applications. Outside the DEX public chain, CoinEx Chain also includes a Smart Chain that supports smart contracts.
Moreover, as privacy issues on the current blockchain have been criticized, it is one of the core tasks of CoinEx Chain to safeguard users’ privacy. Similar to the Smart Chain, the Privacy Chain specifically supports transaction privacy protection. With cross-chain circulation, it can improve the privacy characteristic of the entire CoinEx Chain ecosystem.
Nowadays, 1.7 million people in the world have no bank accounts; however, among them, two thirds are smartphone users with huge demands for financial services. The public chain will empower DeFi applications’ development and popularization, not only help more companies to seize the huge market opportunity, but also to bring lasting transformations and improvements in people’s lives.
With so many crypto exchanges, what is the future outlook of CoinEx when it comes to the crypto exchange space?
Eddie Jiang: It has been nearly 3 years since CoinEx has been launched, but it’s quite young for an entrepreneurial team. We have seen too many projects’ failures due to governance issues. CoinEx has a very elite team with high technical and management capabilities. In terms of business, CoinEx has gradually developed with diversified business and a complete ecosystem. It’s clear that the market will still grow very fast in the future, and the market size is still very large. We will continue to improve our products, put more efforts in marketing and operations, as well as look for more high-quality projects, to increase the number of users and transactions on the platform. Lay a solid foundation, and I’m sure the time will come for us to shine.
What updates is the CoinEx team most excited for?
Eddie Jiang: We are very excited about the National Expansion Plan which will be launched later this year. It is an important part in CoinEx’s globalization strategy. We will actively explore some new markets while consolidate the original ones. CoinEx will set aside 10 million US dollars to set up a “Pioneer Fund” to support this plan. This fund will be used to support local cryptocurrency projects and promote the development of the local cryptocurrency communities through investment or cooperation. Our goal this year is to invest in projects and communities that are conducive to expanding the CoinEx ecosystem in countries with high development potential.

Challenges

  1. It is not clear enough yet whether the trichain operation planning can achieve the project’s development goals;
  2. There is limited information on implementation details about cross-chain and other related technologies, and the development status needs to be assessed based on the later project development disclosure information;
  3. The team currently hold a large share of the token, hence the distribution of tokens is relatively concentrated;
  4. There are few application scenarios for project tokens, and more ecosystem scenarios need to be developed;
  5. As a deflationary token, CET needs to be balanced by dealing with the contradiction between public chain users and token holders.

Outlook

The development of CoinEx Chain contributes to the future development of CoinEx’s centralized and decentralized exchanges; the concept of trichain operation simplifies the functions of each chain, improving their performance. At present, there are few exchanges working on the public chain, and no fierce competition has occurred.

Conclusion

Considering the status and development prospects of the project, TokenInsight gives CoinEx a rating of BB with a stable outlook.

1. Multidimensional evaluation


2. Project analysis

CoinEx (CoinEx Technology Limited) was established in December 2017 and is headquartered in Hong Kong, China. It is a sub-brand of the ViaBTC mining pool. At present, CoinEx’s business scope includes CoinEx exchange, CoinEx public chain, and CoinEx decentralized exchange. The current development focus of the CoinEx platform are public chain and exchange. The main purpose of the public chain is to build a decentralized exchange (DEX) infrastructure and an ecosystem around DEX.

2.1 Introduction

“ CoinEx Chain uses the parallel operation of three chains which are DEX, Smart, and Privacy, as well as cross-chain technologies to create a rich decentralized exchange ecosystem and blockchain financial infrastructure.
The core of CoinEx’s early business was the exchange, consisted of two major categories which were spot and derivatives trading. Currently, there are 123 trading currencies online, covering 302 trading pairs. On June 28, 2019, CoinEx released the CoinEx Chain public chain white paper, aiming to build a decentralized trading system (CoinEx DEX) with community-based operations and transparent transaction rules, and providing user-controlled asset trading scenario by the highest technical standards in the industry; CoinEx Chain has become another development focus of CoinEx. CoinEx Token (CET), which was originally a native token of the CoinEx exchange, will also be developed mainly as a built-in token of the public chain.
CoinEx Chain is a public chain based on the Tendermint consensus protocol and Cosmos SDK, and it uses POS mechanism. CoinEx Chain plans to support 42 nodes when the project starts, and any entity in the ecosystem can participate in the validator’s campaign by staking CET. CoinEx Chain will use the new block reward and the transaction fee contained in the block as the reward for running the node.
CoinEx Chain has developed three public chains with different positioning and different functions in order to meet the needs of blockchain transactions for transaction performance, smart contracts, and privacy protection at the same time. They operate in parallel and collaborate with each other through cross-chain technology. At present, the block time of the public chain is between 2–3 seconds. According to the observation of TokenInsight, the block time is stable, but the number of transactions through the CoinEx public chain is still low at present, the number of transactions in 24 hours is about 30,000; The TPS on public chain disclosed by CoinEx can reach up to 1500 per second.
CoinEx Chain uses a trichain parallel model to build a more vibrant ecosystem around DEX. The three chains are DEX public chain, Smart public chain, and Privacy public chain, respectively responsible for decentralized transactions, smart contracts, and on-chain privacy protection.
CETs that need to participate in complex financial contracts can be transferred to the Smart public chain through the DEX public chain, then moved back to the DEX public chain after that. CET tokens that need to participate in token confusion can also be carried out through the privacy transaction of the Privacy public chain, and can eventually be returned to the DEX public chain. The three public chains are responsible for their respective duties, and they are interconnected through the cross-chain technology through the relay mechanism. In addition to ensuring their respective transaction processing speed and functional attributes, they can also jointly provide richer and safer functions, and synergistically constitute the CoinEx decentralized public chain ecosystem.
In addition, CoinEx Chain also supports any participant to issue new tokens on the chain and create new trading pairs for the issued tokens. CoinEx Chain guarantees the circulation of new tokens by establishing a trading pair between the new token and CET.

2.2 Component architecture

“ Tendermint Core and Cosmos SDK have improved the performance and operation capability of the blockchain. The SDK packaging reduces the consideration of non-related logic, hence reducing the development complexity.
CoinEx Chain is based on Tendermint Core and Cosmos SDK, both of which have brought a big boost to the development of CoinEx public chain performance. Cosmos-SDK will implement the application logic of the blockchain. Together with the Tendermint consensus engine, it implements the three-layer architecture of the CoinEx public chain: the application layer, the consensus layer, and the network layer.
Tendermint
Tendermint is based on the state machine replication technology and is suitable for blockchain ledger storage. It is a list of transactions making consensus with Byzantine fault tolerance, the transactions are executed in the same order, and eventually the same state is obtained. Tendermint can be used to build various distributed applications.
Cosmos SDK
Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains.
Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains. The blockchain development framework Cosmos SDK implements general functions such as account management, community governance, and staking in a modular form. Therefore, using the Cosmos SDK to build a public chain can simplify development procedures and facilitate operation. Tendermint is a fixed protocol in a partially synchronized environment, which can achieve throughput within a delay range of the network and each process itself. The CoinEx public chain is developed based on both, improving the performance and operability of the blockchain. The SDK packaging further reduces considerations of non-related logic and reduces the complexity of developers creating. The two components of Tendermint and Cosmos SDK are connected and interacted through the Application Blockchain Interface.

2.3 Project public chain planning

The development plan of the CoinEx public chain is to create a series of public chains with specific application directions, including:
  1. DEX public chain: solve the problems of lack of security and opacity that are widely criticized by centralized exchanges at present; aim to build a transparent, safe, and permission-free financial platform; restore the experience of central exchanges to the greatest extent;
  2. Smart public chain: a public chain that specifically supports smart contracts and provides a platform for building complex financial applications;
  3. Privacy public chain: mainly provides transaction amount, account balance, and information protection and the hiding of both parties to the transaction.
In order to achieve the performance of each specific application public chain, each public chain in the CoinEx public chain focuses on the development of a certain function. For example, in order to improve the transaction processing speed of the DEX public chain, the DEX public chain only supports the necessary functions and does not support smart contracts. To achieve the smart contract function support, cross-chain connection between the DEX public chain and the Smart public chain is required.

2.4 Operation analysis

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

2.4.2 Roadmap
CoinEx Chain released its development roadmap for the four quarters of 2020 in January 2020. The roadmap shows that CoinEx Chain will undergo major updates on smart contracts and DEX hard fork upgrades. The project roadmap is basically planned on a monthly basis, with a clear plan and a clear direction of development.
CoinEx Public Chain 2020 Development Roadmap,Source: CoinEx; TokenInsight
In addition to the development route planned in the roadmap, CoinEx public chain also discloses its goals for next month in its monthly ecological report. The project’s main net was launched online in November 2019. According to TokenInsight’s review of the development of CoinEx public chain from January to April and the disclosure of the project’s ecosystem monthly report, the project’s plan about development of the smart contract Demo in February failed to be completed as planned; the project completed launching of the new version of the blockchain browser and the Asian Atlantis upgrade; the smart contract virtual machine development was planned to be completed in April, but the progress related to supporting cross-chain agreements was not disclosed yet.
Overall, the project’s development route planning is clear, and the project’s development schedule is consistent with the plan, but there are still some discrepancies. Operation and development information is disclosed every month, and information transparency is high.

3. Industry & Competitors

The earliest origin of the exchange layout in the public chain field began in early 2018 when Binance released an announcement to start the development of the Binance Public Chain officially. In June of the same year, Huobi announced at its brand upgrade conference that it will combine the technical capabilities of the Huobi technical team and the community developers to develop the Huobi public chain called “Huobi Chain”. In December of the same year, OK Group announced the launch of its self-developed public chain OKchain, dedicating to provide underlying technical support and services for startups stationed in B-Labs.
The successful launch of the public chain brings huge strategic significance to the exchange, which can not only improve the performance of the existing business of the exchange but also achieve further expansion of its influence. As one of the most important blockchain infrastructures, the public chain can benefit the exchanges behind it.
As a platform for developing public chain technology exchanges, CoinEx’s main competitors in the field of public chain development include Binance, Huobi, and OKEx. Although they are all exchange platforms for deploying public chains, the above four are different in terms of specific functions, economic models, and critical points of the public chain.

3.1 Development progress comparison

In 2019, Binance became the first exchange to launch a public chain among all digital asset exchanges, and its main product is Binance exchange (DEX). In April 2020, Binance announced the launch of a second smart contract chain, using Ethereum’s virtual machine, so that developers can build decentralized applications without affecting the performance and functionality of their original chain.
OKEx launched OKChain’s testnet in February 2020 and completed open source two months later. OKChain is designed as the basis of large-scale blockchain-driven business applications, with the characteristics of source code decentralization, point-to-point, irreversibility, and efficient autonomy.
Huobi released Huobi Chain for the first time in July 2019, the code is open source, and the testnet was released in February 2020. As a “regulator-friendly financial blockchain”, Huobi Chain focuses on providing compliance services for companies and financial institutions.
The CoinEx public chain officially completed the main online launch in November 2019 and completed the new block browser’s launch in March 2020. On April 3, 2020, CoinEx DEX uploaded the underlying code to Github to achieve open source. The CoinEx public chain is more inclined to build a full DEX ecosystem to achieve a one-stop solution for issuing, listing, storing, and trading. The long-term goal is to create a blockchain financial infrastructure.

3.2 Comparison of economic models

At present, the exchange is more inclined to use its existing platform currency as the native token of the public chain in the construction of public chain ecology. CoinEx’s CET, Binance’s BNB, and Huobi’s HT all fall into this category. OKEx is the only exchange that issues new tokens for its OKChain, which means OKT is the only ‘inflation token’ in the exchange’s public chain, while CET, HT, and BNB are all deflationary.

3.3 Decentralization of public chain

The initial number of CoinEx public chain verification nodes is 42, which is currently the most decentralized among all exchange public chains, and able to take both efficiency and decentralization into account; OKChain also currently has a relatively high degree of decentralization in the exchange public chain (21 verification nodes), its nodes have a high degree of autonomy; by contrast, Binance still firmly controls the operation of nodes and transactions; In terms of encourages cooperation between regulators and the private financial aspects, Huobi provides a lesser degree of decentralization. Huobi Chain uses a variant of the DPoS consensus algorithm to provide functions such as “supervision nodes”, allowing regulators to become validators.

4. Token Economy

CoinEx Token (CET) is a native token of the CoinEx ecosystem. It was issued in January 2018. Token holders can enjoy some user value-added services within the ecosystem. Currently, it is mainly used as a native token on the CoinEx Chain. As of 11 am on April 23, 2020, the current circulation of CET tokens in the market is 3,215,354,906.31, with a total of 5,842,177,609.53. CET tokens will not be further issued or inflated. Currently, daily repurchase and quarterly destruction are carried out. The repurchase destruction dynamics can now be tracked real-time on the CET repurchase system on the platform.

4.1 Token Distribution

The CET token used to be based on the ERC-20 token developed by Ethereum. Since the CoinEx Chain mainnet was launched in November 2019, some ERC-20 CET tokens have been mapped to the mainnet CET, and the rest of the CET will be mapped before November 10, 2020. CET holders need to deposit ERC-20 CET to the COinEX exchange, and the exchange will conduct the main network mapping.
At present, CET is mainly circulated in the form of mainnet tokens, and only a small portion of ERC-20 CET has not been mapped. The distribution of token holdings currently circulating on the mainnet can be seen in the figure below. At present, the number of tokens held by the top ten holders accounts for about 60.44% of all mainnet CET tokens.
Distribution of CET token holding addresses,Source: Etherscan; TokenInsight
The following figure shows the initial distribution of tokens after the mainnet mapping preset by CoinEx. From the initial distribution map of CET, it shows that, after mapping, a large portion of CET remains concentrated in the hands of the team (31%), and the actual number of CET circulating in the market only accounts for 49% of the total.
The initial distribution of CET token,Source: CoinEx; TokenInsight
After the main net mapping, the 31% of the total CET (1.8 billion) held by the team will be gradually unlocked in the five years from 2020 to 2024, and 360 million CET will be unlocked each year. By 2024, the CET held by the team will be completely unlocked. From the current CET dynamics, the CET share held by some teams has been used for destruction purposes to achieve the purpose of CET austerity. If the frozen 1.8 billion CET held by the team are used for similar purposes, the development of CET and its platform can benefit from it.

4.2 Token economic model

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

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

Let's discuss some of the issues with Nano

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.
00:12 Spam
Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly. Similar to TCP/IP, email servers, and http servers. Just like Bitcoin full nodes.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.
Obviously there is still a lot of work to be done in some areas, but overall I think Nano is a good place. For people that aren't Nano fans, what are your biggest concerns?

Weekly Crypto News — July, 13 (Bitcoin, Vechain, Visa, Binance, and other)

What important crypto events happened last week?

Regulation, Government, Mass Adoption

📌 Visa has posted a vacancy for blockchain developers. Potential employees will create decentralized applications. Visa requires experience with Ethereum, as well as the ability to work with the Bitcoin, Ripple, R3 blockchains and the Solidity programming language. Employees will be part of a team dedicated to creating innovative “non-card” payment products for Visa.
📌 Binance-backed blockchain hotel reservation service Travala has announced a partnership with Expedia, a US travel agency. Thanks to this, it will be possible to pay for rooms in 700,000 hotels from the company's catalog using Bitcoin.
📌 Bitcoin industry veteran, venture investor and billionaire Brock Pierce announced his intention to compete in the upcoming US presidential election. Pierce noted that he is going to the polls as an independent candidate. The campaign will be held under the slogan “Leadership. Experience. Values ”, but there is currently no specific program that Pierce intends to offer voters.
📌 Zap and Visa will release a payment card for Bitcoin payments. Jack Mullers, developer of the popular lightning wallet Zap Wallet, has announced the launch of Strike's open beta. With it, users will be able to make payments in Bitcoin through direct bank transfers.
📌 The Central Bank of Japan announced the start of testing the digital yen. According to the statement, at the first stage of testing, the bank intends to evaluate the possibility of launching the coin from a technical point of view and will consider the reliability of such a tool and its availability to the general public. Meanwhile, China is already in full swing testing digital yuan in 4 cities in such large networks as McDonald’s and Starbucks.
📌 The United States Internal Revenue Service (IRS) has launched an investigative pilot program that seeks to find tools to track various types of cryptocurrency transactions. These include private coin analysis software and second-tier protocols such as the Lightning Network. The tools will be used by investigators, who in their work face the need to unravel the movements of privacy-oriented cryptocurrency users.

Coins, Projects, Startups

📌 VeChain rose 73% amid a conference with Microsoft and Amazon. The market value of cryptocurrency has grown by 73% over the past five days, updating a two-year high. Thanks to this, the coin returned to the top 20 digital currencies by capitalization.
📌 Binance has announced the distribution of BinanceTurns3 collectible tokens, released in honor of the platform’s third birthday. BinanceTurns3 are non-fungible (NFT) tokens with unique properties. NFT has no practical use, but they can be bought and sold at auctions. The cost of previous Binance NFTs reaches several thousand dollars. The most expensive token was sold at the OpenSea marketplace for $5,000.
📌 The developers of the Ravencoin cryptocurrency recommended that miners activate an emergency update after a vulnerability was found. The bug resulted in excessive emission by Raven Coin attackers in excess of the established block reward of 5,000 RVN (~$91). User assets were not affected.

Blockchain, Mining

📌 Sino Global Capital CEO Matthew Graham announced the sale of Filecoin mining equipment (FIL) in China, which surprised the expert. In the Filecoin system, miners receive a reward for storing information, so Graham doubted the need for special equipment. The main network of the project has not yet been launched. Thomas Heller, F2Pool Mining Pool Global Business Director, confirmed that sales are made only in China.
📌 The head of Tesla and SpaceX, Elon Musk, a year later denied speculation about participating in the creation of solutions on Ethereum. In the crypto community, the entrepreneur was thought to participate in projects with ETH. In April 2019, Musk tweeted with the word “Ethereum”. Subsequently, he made a reservation that it was a joke. Elon Mask still considers Bitcoin the most reliable cryptocurrency, although he owns only 0.25 BTC.

Survey Responses Are IN!

I want to thank everyone who replied to our survey! Your feedback is extremely valuable!


Here are the results and how they're helping shape our direction.


What goals would you like to see us accomplish? What's most important to you in how this Quadriga situation ends?

This was an open-ended question and the answers varied widely (and there was definitely a lot of responses which mentioned multiple goals). Here's a summary:
The justice theme has been entirely overlooked by what we're doing. Discussing the idea on the Quadriga Uncovered Telegram group, it was determined that there was definite interest in a potential letter-writing initiative. One possibility would be sending letters to the RCMP to request the exhumation.


Is there any part of our initiative which confuses you?

Almost universally, there was no mention of any confusion.
The feedback we did receive:
Please feel free to reach out on Telegram and Reddit if there are any further questions!


Is it more important to you that we focus on (a) helping victims of Quadriga recover, (b) educating more people about Quadriga and other exchange fraud, or (c) preventing future exchange fraud events like Quadriga?

Of the first or only choice picked, 70% chose (a) helping victims of Quadriga recover, while 30% chose (c) preventing future exchange fraud events like Quadriga.
(a) was mentioned in 80% of cases, and top choice in 70%.
(b) was a second choice in 30% of cases and mentioned in 35%.
(c) was mentioned in 65% of responses and top choice in 30%.
The educational portion of our initiative was seen as the lowest value. We are floating the idea of replacing the Education goal with a separate Justice goal, which is composed of letter-writing and other advocacy to help speed up any potential criminal investigations.


What bothers you most about Canadian cryptocurrency exchanges?

The responses varied widely. Here's a selection:
There is clearly a lack of satisfaction.


Should preventing events like Quadriga focus more on regulatory reform (working with regulators) or trying to create change through setting the example on one exchange and go from there (similar to how "Tesla" has electrified vehicles)?

Overall summary:
Pressing forward on both fronts appears to make the most sense.


Would you rather have the recovery run inside of a for-profit exchange (sort of a marketing/promotion idea to push people onto a safer exchange) or as an independent group of affected users pushing for our own interests (working with the safer exchange and other businesses potentially similar to a labour union or political advocacy)?

The end result:
We will be working to run this independently, however working closely with our partner exchange as a joint project (and it is definitely a promotional tool for them).


If given the choice, would you prefer (a) $20 cash each year for 10 years (slower recovery with full choice), or (b) your choice of $200 worth of discounts on products/services that are donated by small businesses which you could use this year (faster recovery with less choices)?

60% indicated a preference for (b), and 40% had the preference for (a). There is clear interest in focusing on both, which will push the fastest and most flexible recovery.


Affected users have a liquidation option which allows non-victims to purchase their tokens on the exchange. How do you feel about charging non-victims a small fee (5 cents per token) that is split between funding the project and a pool for affected user payout?

50% expressed outright support for the idea. Below are more detailed responses and comments:
At the moment this has not yet been agreed upon by the partner exchange.


Have you discussed the project with anyone else who lost funds in Quadriga? What kind of feedback are you hearing?

40% said they've discussed it. 40% have not. 20% didn't answer (or it was hard to understand). Some of the responses:


Many affected users have strong privacy concerns and shame regarding what happened to them, such that they are even hesitant to share basic details. What do you feel is the best way to build trust and openness among the affected user community?

Here are some of the replies:

Notes: Percentages rounded to the nearest 5%.


Thank you very much for everyone who took the time to respond! We will continue to study your answers as we move forward!

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.
