Abstract
Recent work has demonstrated significant anonymity vulnerabilities in Bitcoin's networking stack. In particular, the current mechanism for broadcasting Bitcoin transactions allows third-party observers to link transactions to the IP addresses that originated them. This lays the groundwork for low-cost, large-scale deanonymization attacks. In this work, we present Dandelion++, a first-principles defense against large-scale deanonymization attacks with near-optimal information-theoretic guarantees. Dandelion++ builds upon a recent proposal called Dandelion that exhibited similar goals. However, in this paper, we highlight simplifying assumptions made in Dandelion, and show how they can lead to serious deanonymization attacks when violated. In contrast, Dandelion++ defends against stronger adversaries that are allowed to disobey protocol. Dandelion++ is lightweight, scalable, and completely interoperable with the existing Bitcoin network. We evaluate it through experiments on Bitcoin's mainnet (i.e., the live Bitcoin network) to demonstrate its interoperability and low broadcast latency overhead.

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.

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.

Tortuga: The lightweight, non-custodial, self-hosted payment gateway you've been waiting for!

I'm very pleased to announce the availability of my payment-gateway project: Tortuga.
Tortuga lets you sell a digital file for cryptocurrency. All you need to be able to do is run a docker container (I run mine on a little VPS from digital ocean).
Benefits:
Current Limitations:
Supported cryptocurrencies:
You can read more about it at https://github.com/unyieldinggrace/tortuga
The deployment instructions on the github page should be sufficient for technical users. I'll try to make time to write a step-by-step setup tutorial on read.cash at some stage (or if someone else wants to do it, that might be a good way to score tips!).
Motivation:
I made this payment gateway for idealistic reasons. I wrote a book called Taxation is Slavery: The Biblical Case for Libertarian Politics. Among many other things, this book argues that fiat money-printing is a form of immoral counterfeiting, and that we should attempt to secede from the fiat power structures by using cryptocurrency. To live that out, I was determined to find a way to sell the book directly to readers, completely peer-to-peer. In this way, I'm helping to "close the loop". I'm giving people something good to spend their (crypto) money on, without either them or me ever having to convert it to fiat.
The book also includes a brief sub-chapter on how the very existence of Bitcoin should force many Christians to re-evaluate the way they understand Jesus' statement about "giving to Ceasar what is Caesar's". Bitcoin has no president or king's face on it. There is no engraving of any Caesar. Thinking this through might be of interest to many Bitcoin fans :)
Ready to see it in action?
You can test out the payment gateway by seeing how I use it on my own site. Just click one of the crypto checkout buttons at https://beingbiblical.com/books/taxation-is-slavery

PT Super Public Chain has the potential to outperform all mainstream public chains

PT Super Public Chain has the potential to outperform all mainstream public chains
Public chains have become a topic that is widely discussed, and it used to be all about comparing who had the better headlines and everyone was talking about Blockchain 3.0. Their normal method was to take a prominent indicator and make comparisons between them and a mainstream public chain in the market, and then come to a predetermined conclusion. Few articles objectively and comprehensively compare the current mainstream public chains in the market and give the public an intuitive and credible conclusion. Today, we are going to break this bad habit of this industry and make a horizontal comparison of the current mainstream public chains, and thus intuitively and objectively tell you what the differences are between public chains.

https://preview.redd.it/heczp9tj29t51.jpg?width=1772&format=pjpg&auto=webp&s=cbac81221394b3d5294b8c6eb1be52581b0d725f
Contestants:
First generation public chain: BTC (father of blockchain)
Second generation public chain representatives: ETH, EOS
Third generation public chain representatives: polkaDOT, VDS, PT public chain
Criteria for the different generations: classification

  • First generation public chain: mainly referring to the transformation from theory to the implementation of blockchain, Bitcoin is recognized as the representative of the first generation of blockchain.
  • Second generation public chain: the main purpose is to explore the possibility of blockchain applications, among which ETH is the representative. Although EOS claims to be the third-generation public chain, it really should belong to the enhanced version of the second-generation public chain.
  • Third generation public chain is on top of the second generation. It has generally found its niche, and comes with more valuable technical public chains, such as VDS resonance, or polkaDOT’s superb cross chain innovation, PT public chain's full chain compatibility mode and ultra-high throughput.
Four dimensions for comparison:

  • Public chain consensus: the core indicator of public chain innovation, which directly affects the performance and security of the public chain, with a top score of five stars.
Usage scenarios of the public chain: it mainly reflects the commercial value of the public
  • TPS: before upgrading to the 2.0 network, the TPS of ETH can only handle 30 transactions per second, which is considered to be in the weak category, and thus I can only give 1.5 stars.

  • Influence: the representative of the second generation blockchain, giving it 4 stars.
To sum up, the average score of the second-generation public chain ETH is 3.625 stars.
EOS (Second generation public chain):

  • Consensus: OPOS is a new set of consensus created in addition to POW, which perfectly avoids the shortcomings of the POW consensus mechanism. However, its own security has not been recognized by the community. Coupled with the existence of a centralized "referee mechanism", DPOS on the EOS chain has always received mixed reviews in the industry. At this stage, it only deserves a 3-star rating.

  • Usage scenario: thanks to the improvement of the consensus mechanism, EOS has the possibility of being suitable for large-scale applications. There have also been popular applications such as Pixel Wars. However, due to the high rental costs of CPU resources, developers are becoming more and more distant from the EOS ecosystem, and it has been a long time since there have been any popular new applications, so only 2.5 stars.

  • TPS: EOS claimed to have a million concurrency at the beginning of development, but the actual tested volume is 3800 transactions per second at the moment. Compared with the first two public chains, this was a major breakthrough, scoring it 5 stars.

  • Influence: at the beginning when launched, there was a massive wave of interest but then there were no popular applications and the ecosystem has gradually withered away, so influence gets only 2 stars.
To sum up, the average score of the second-generation public chain EOS is 3.125 stars.
polkaDOT (Third generation public chain)

  • Consensus: NPOS is an updated consensus, based on an improved DPOS. The double confirmation mechanism makes it more difficult for nodes to be corrupted, but the cost is higher, so taking into account the utility of the public chain performance, I’ll give it 4 stars.

  • Usage scenarios: polkaDOT provides a cross-chain relay chain mode, and its own positioning is to connect highways without public chains. At present, there is still a lack of real demand in terms of practical scenarios. So far, polkaDOT has been in a tepid state, giving it 3.5 stars.

  • TPS: the processing is 1000 transactions per second on the chain, and taking into account the safety and efficiency, this is a relatively ideal performance, giving an overall score is 4 stars. United States, but at present, based on its budding state, it can only score 2 stars for the time being.
    To sum up, the average score of the third-generation public chain PT is 3.5 stars.
In summary, from the score point of view, the scores of the three generations of public chain are beyond my original expectations. The second-generation public chain is still the preferred platform for mainstream applications, with mature technology, a friendly development environment and low user education costs being the key advantages. However, the third-generation public chain, as a latecomer, generally has a lower score. The technical purposes of the third-generation public chain are very obvious, so there is the phenomenon of partiality. Some of the main functions came close to a full score, while the rest scored relatively low.
https://preview.redd.it/vic3k7j049t51.jpg?width=3334&format=pjpg&auto=webp&s=27a24ce91445d25881d25a8ac8abbbdffbf82a8f
I am very optimistic about the PT public chain. As a latecomer, PT public chain has the first decentralized Dpos+Spos consensus mechanism in the blockchain circle. It has high security, high privacy levels, high efficiency, high capacity expansion, supports compatibility and cross chain technologies, which makes it easier to carry out multi technology development. It also innovates the efficiency of the destruction mechanism of mining coalescence, effectively improving the shortcomings of the traditional mining allocation mechanism, eliminating speculative players, and increasing the participation rate of consensus innovation in the technology and methodology. However, due to the weakness of the latecomers themselves, the ecosystem is in its infancy, and there has not been enough time for all of the innovative mechanisms to be tested by the market, so I can
chain and is an important basis for measuring the commercial prospects of the public chain, with a top score of five stars.
  • TPS of public chain: represents the maximum potential upper limit of the public chain, with top score of five stars.
Influence / achievement of public chain: represents the contribution value of the public chain to the blockchain industry, with a top score of five stars.
These four dimensions mainly consider the practicability of the public chain, and focus on the commercial value itself, as I believe that productivity is the only standard by which to measure technology.
BTC (first generation public chain)

  • Consensus: POW (workload proof mechanism) this is a consensus with the highest degree of security and decentralization so far. The disadvantage is that it is less efficient, because it is the pioneer of POW, so we will give it a great score of 4 stars.

  • Usage scenario: digital currency (payments, transfers, asset management) although BTC is currently the most commonly accepted digital currency, it has a single purpose. We give it a score of 2.5 stars.

  • TPS: it can only process 7 transactions per second, which is also the major factor restricting the popularity of BTC at present. This was a technology compromise in the initial start-up stage, we can only rate it 1.5 stars.

  • Influence: the father of blockchain, the founder of digital currency, it has to be the top score of 5 stars.
To sum up, the average score of the first-generation public chain is 3.25 stars.
ETH (Second generation public chain)

  • Consensus: POW (Proof of Workload) it is the same as bitcoin's consensus mechanism, and its advantages and disadvantages are also basically the same. The difference is that ETH has added an algorithm against mining machines, which makes the computing power more decentralized. In addition, the witness mechanism of DPOS was introduced in the era of ETH2.0, which means I can give a score of 4 stars.

  • Usage scenario: in terms of applications, ETH is invincible. It has the largest user group and developer team in the industry. It has produced popular and even quasi killer applications like Cryptocat, FOMO3D and DEFI, which is the king of blockchain applications. This gives it a full score of five stars.
  • Influence: the influence is limited to a small portion of the technology exploration community, giving it a 2.5-star rating.
To sum up, the average score of the third-generation public chain polkaDOT is 3.5 stars.
VDS (Third generation public chain)

  • Consensus: due to the lack of powerful computing power to support it, the safety and the performance of the public chain have basically not been considered, so, only 1.5 stars can be given.

  • Usage scenario: it has its own resonance mechanism, and it is no exaggeration to say that VDS was the most popular public chain in 2019. It immediately gained explosive popularity in the industry. We have to give credit to this kind of strength, scoring it 4.5 stars.

  • TPS: the official marker is 60,000 transactions per second, but there is no way to evaluate it, and only one star is given.

  • Influence: the once explosive project is now a thing of the past. All of the ecological hot spots have already been extinguished and only one star can be given.
To sum up, the average score of the third-generation public chain VDS is 1.875 stars.
PT Public Chain (Third generation public chain)

  • Consensus: DPOS+SPOS, double consensus. This is the application of the latest blockchain research results, which effectively balances the differing demands of security, efficiency and decentralization. It may become the mainstream in the future. Here I’m giving a high score of 4.5 stars.

  • Usage scenario: built-in cross chain, quantum computer confrontation, and has the first multi-currency aggregate mining mode. At present, PT public chain is the only fair chain in existence with zero pre-mining, zero reservations and zero handling charges. It is a public chain with long-term development potential. The PT public chain has just been put online, and the current ecosystem is still far from perfect, so, only scoring 4 stars.

  • TPS: under the normal condition of the main chain, the processing speed of 4,000 transactions per second is excellent, but the PT public chain also has a hidden power-up mode. Once the fragmentation mechanism is enabled, processing speed of up to 100,000 transactions per second can be achieved, which is quite amazing data. At present, it can only be given 3.5 stars based on the normal state.
Influence: as a public chain, PT has utilized a lot of new technology research, and also has a lot of innovation built into the operations. Recently, it has become popular in Europe and the only give it a low score unfortunately.
However, this score can only be used as a reference based on the specific current environment. Over time, the public chain ecosystem has had its ups and downs, user migration, pop-ups, technology iterations, etc., I still believe that the public chain, with its technical advantages and model innovations, such as PT, can stand out in the market, and time will be the best witness. Just as the PT white paper says, you will slowly get rich together if you make the right choice.

Why AMP is a threat to the Open Web

What is AMP?
AMP is an open-source web component framework developed by the AMP Open Source Project, first announced by Google in 2015 as a reaction to Facebook’s Instant Articles and Apple News. While it was originally aimed at accelerating mobile pages (hence AMP), it’s now a much broader project aimed at improving the UX of websites, stories, ads and mail. The AMP framework consists of three components: AMP HTML, which is standard HTML markup with web components; AMP JavaScript, which manages resource loading; and AMP caches, which serves and validates AMP pages.
In plain English: AMP is Google’s attempt at making pages (and more) faster. They did a good job, pages built with the AMP framework will normally load faster. However, as this article explains, you won’t notice much of a difference unless the AMP library is served using the AMP cache, but more on that later.
The controversies with cached AMP pages
The AMP format is itself not much of a problem. In fact, we should applaud search engines that give ranking preference to fast-loading pages like AMP, but four aspects of its implementation are flawed:
  1. Google mobile Search’s Top Stories carousel has a premium position above of all other results, which is only accessible for AMP pages. These pages have to use a technology that was build and maintained mostly by Google (of the top 10 contributors to the AMP project on GitHub, 9 are Google employees), are then served by Google from their infrastructure and placed within a Google controlled user experience. And since this carousel generates a lot of clicks and revenue, publishers are left no choice but to embrace AMP. This has the effect of further reinforcing Google’s dominance of the Web. Fortunately, Google has announced that it's working on opening up the Top Stories carousel to non-AMP pages in 2021.
  2. The biggest performance boost doesn’t come from the AMP framework, but from preloading the page. It begs the question: Should preloading really be exclusive to AMP? They could introduce a way for publishers to allow or disallow preloading and if Google sees fit, they could preload those pages too, alongside AMP.
  3. When a user navigates from Google to a piece of content Google has recommended (or when a user clicks on a shared cached AMP link), they are, unwittingly, remaining within Google’s ecosystem and the publisher’s domain is obscured by the google.com/amp prefix. To work around this Google introduced Signed HTTP Exchanges ([Draft], [1], [2]), a web-standard that allows the browser to display the original site's URL, instead of the actual one (the one with the google.com/prefix). This would solve the original issue, but while doing so it introduced new ones (e.g. it obfuscates the fact that they're delivering the AMP page you're visiting). Interestingly enough, Google's Chrome already has support for this technology, but parties not involved with AMP are not so enthusiastic: Mozilla has deemed it a harmful web standard [2], and Apple has taken a similar stance.
  4. Google’s entire business model is about collecting as much personal data as possible, AMP is just another tool to do so. As described in Google’s Support article:
“When you use the Google AMP Viewer, Google and the publisher that made the AMP page may each collect data about you.”
The controversies with non-cached AMP pages
To be clear, the above flaws are only with AMP pages cached by Google (or another party like Bing or Cloudflare) but there are also plenty of pages simply utilizing the AMP framework, recognized by URLs such as bbc.com/news/amp/. However, these are also problematic, mainly because there's only a small performance improvement when AMP pages aren't cached and AMP pages tend to be less feature-rich and less diverse than their originals. And in some edge cases, it breaks stuff.
One could argue that the more popular the AMP framework becomes, the more AMP threatens the open web. That said, it should be clear that the biggest problem lies with the cached AMP pages.
AMP is open source, but that doesn't make it holy. Or as Ferdy Christant puts it quite nicely in his blog:
Google’s main defense is that AMP is open source. Which isn’t just a weak defense, it’s no defense at all. I can open source a plan for genocide. The term “open source” is meaningless if the thing that is open source is harmful.
Just so we’re clear, I’m not claiming Google or the AMP project is evil (hell, they might even have good intentions!), but the fact is that AMP and it's implementation have some major flaws that threaten the Open Web. And as long as that's the case, AmputatorBot will be there to remove AMP from your URLs.

JDE Project Rating (A)-Convergent Decentralized Financial Agreement

2020 is the year of the outbreak of the DeFi market. As products of the DeFi 1.0 era, Maker, AAVE, and Compound have become the infrastructure of DeFI. Innovative projects of DeFi 2.0 represented by Uniswap and YFI have gradually attracted the attention of the market. Currently, DeFI 3.0 has emerged, technology innovation + business model innovation has become the theme of 3.0, and innovative projects represented by JDE have gradually occupied the market. This article focuses on the analysis of the JDE project and comprehensively evaluates the JDE project.
Project Positioning——A-
JDE is called Just for Decentralization. The project is positioned as a decentralized DeFi aggregator protocol. In the current DeFi market, each product is an independent agreement, providing users with independent products. For the user side, every DeFi project operation has a certain threshold. If a user selects multiple DeFi products at the same time, the complexity of the operation will be much higher. JDE's centralized decentralized protocol can better satisfy users' multi-faceted and full-ecological services. You can enjoy DeFi financial services with only one key operation.
Aggregation services are the most urgent needs of users in the current market. For example, similar to loan product AAVE, wealth management product Maker, insurance product NXM, etc., users must perform separate operations on each platform if they want to achieve their needs. The high threshold of DeFI will also prevent some users from entering this decentralized world.
JDE provides a complete protocol suite to allow users to perform fool-like one-key operations. On JDE's platform, it includes loan agreement, payment agreement, insurance agreement, decentralized transaction agreement and Game ecological agreement. Users can operate a variety of decentralized financial products on the protocol cluster. This positioning is very in line with the needs of current DeFi market users, and can serve millions of DeFi industry users to provide accurate services.
Project Technology-A
The DeFi project has high technical requirements. Each agreement is an independent individual, so a complete financial agreement aggregator has higher technical requirements. The technology of JDE has been developed for many years. JDE has created an on-chain and off-chain two-layer solution, which allows each protocol to be completed quickly in a short time, and the protocol cluster can also complete the interaction more quickly. Compared with other platforms, JDE's contract interaction time can be reduced by 60%. JDE's Layer 2 solution transfers transactions and transfers on the chain to off-chain, completes a Transaction off-chain, and then performs backup packaging on the chain. At the same time, JDE has added Aztec, a completely anonymous privacy protocol, which can provide more secure and anonymous services than Bitcoin. The following is the technical architecture diagram of JDE
JDE implements Full Stake DeFI on the technical side. As the basic ecological platform, JDE integrates mainstream products in the DeFi 1.0 and 2.0 eras, such as Maker, AAVE, BZX, Uniswap, Curve, YFI and other projects. It also provides projects based on ETH Full Stake DeFI, an independent solution, builds mainstream DeFi application components. Realize one end to meet all DeFi requirements.
JDE's protocol cluster will choose the most suitable product for users from mainstream products and products built by itself, make intelligent judgments between profitability and security, and then launch products that are most suitable for users. According to the needs of users, it will intelligently choose the products that best meet the users.
Each parameter in the JDE aggregation protocol will go through dozens of demonstrations to ensure that each parameter is in the safest state. JDE's technical teams are all from well-known companies around the world, and have a very deep technical foundation in the blockchain field. Compared with the technology of many DeFi projects on the market, the technical requirements of JDE are more complex. The technical aspect scored A.
Product solution——A+
JDE provides the safest guarantee for products at the bottom of the technology. Provides the most comprehensive and complete ecological services on the product side. JDE Ecology provides DeFI financial product solutions including asset pools, loan products, payment wallets, trading products DEX, insurance protection products, game products, etc.
Throughout the current DeFi financial products on the market, they can only provide a single product and service. But on the JDE platform, users can enjoy all aspects and the entire ecosystem of financial services. From the most basic asset pool for mining, lending to payment, to decentralized DEX platform transactions, insurance services, and game product services. Covers the various needs of mainstream users.
The product solution combines the various needs of the market. Focus on the asset pool JDE DAO Pool-V1. This is a more popular mining product today. In this product of JDE, users provide liquidity by depositing mainstream assets ETH, wBTC, USDT, etc., and can perform lending and DEX liquid pool transactions on the platform. Here the user's mortgage loan is a full mortgage, so the platform transplantation can be guaranteed to be in a safe state. When the user's mortgaged assets cannot cover the user's loaned assets, the platform will automatically liquidate. At this time, the platform will charge a 5% liquidation fee.
JDE Ecological DEX trading products are also the main source of revenue for the platform. The platform will charge a transaction fee of 0.2%, which is the lowest in the entire network. The handling fees of other platforms are above 0.3%. Users can inject liquidity into the DEX platform to become a market maker. The platform is very friendly to the project party, can list currency without review, and provide automated market services. The DEX trading platform can help the platform earn hundreds of thousands of dollars in handling fees (compared to the trading fee of the Uniswap platform).
JDE Eco provides a complete and multi-faceted product solution, and users can enjoy one-stop service. The product angle is rated A.
Economic Model-A
JDE is the first ecosystem in the entire network to successfully implement DAO governance. If you want to make product-related proposals in the JDE ecosystem, you must get the approval of the autonomous committee, which is composed of all currency holders. Each coin-holding user realizes a complete process of autonomy by voting on proposals. JDE's token, JDE, not only has appreciation rights, but also has very large autonomy rights.
Let's take a look at the JDE sub-token economy. The total amount of JDE is 10 million and will never be issued. Among them, 70% is used for community liquidity mining; 5% is owned by the technical team and locked for one year; 1% is for community private placement (20% is issued online, and 10% is released every week); 5% is an insurance pool; 10 % Is the DAO Autonomous Community Ecological Fund.
In the JDE economic model, almost 80% of the tokens are allocated to liquid mining, which is a very high proportion. Early rewards can be given to users who participate in the JDE community early. Users can get liquidity rewards for asset deposits, loans, DEX transactions, etc. in the JDE ecosystem. Only the technical section is allocated to the team, and the position is locked for long enough. 10% is the DAO autonomous community ecological fund, which participates in the DAO autonomous ecology. 5% is the insurance pool, which provides liquidity of funds. 1% is given to community welfare and allocated to users who participated in the early stage.
The profit of the products and services of JDE ecology will be repurchased in the JDE secondary market, which is always in a state of deflation. This economic model provides a long-term development guarantee for the JDE ecology. The economic model community surpasses most projects in the industry. The economic model is scored as A.
Comprehensive analysis, JDE ecology has a layout in the Defi field for many years, and at the same time has a very complete design in project positioning, product solutions, technological development, economic models and other sectors. The products in JDE's product solution will be gradually launched to provide users with the most complete ecological services. The prospects of the JDE project are good. It is currently in the early stages of project development. I look forward to the launch of JDE products to provide users with DeFi ecosystem services!

RiB Newsletter #13 – Stuck inside, hacking away

It was another month in 2020, like previous months in 2020. Stuck inside, hacking away.
We don’t see a consistent blockchain Rust theme to highlight this month, but interesting new Rust crypto and blockchain projects continue to be launched. They are noted in the “Interesting Things” section.
Oasis launched what will probably become their mainnet. Congrats to them!
Ethereum 2 keeps creeping closer, and it looks like Lighthouse, in Rust, might be the fastest implementation.
The Holochain team asked that we highlight the Holochain DevCamp, running until August 27th. Now is your opportunity to learn more about the project. There are a number of other online blockchain hackathons going on this summer, noted in our “Events” section. Could be a good way to spend time this summer instead of going to the beach.
Well, anyway, keep on hacking.

Thanks

This edition of RiB was produced with contributions from Darosior, James Waugh, Ken Shamir, Paulii Good, Taylor Lee, Brian Anderson, and Aimee Zhu. Thank you for your help!
RiB needs help to keep up with Rust blockchain projects. If you follow a particular project, or otherwise find information that is beneficial to the Rust & blockchain community, please contribute to the next issue. Either submit a PR to the #14 draft, or Tweet @rust_blockchain.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
electrs.
electrs is a server for the Electrum Bitcoin wallet, written in Rust. Electrum is a light wallet that needs to connect to a server to transact with the Bitcoin network. Although there are public Electrum servers, and they are safe to transact with, they can deanonymize users, so it might be prudent to run one’s own Electrum server, like electrs , or bwt (also written in Rust).
As mentioned recently in a blog post, Blockstream, one of the primary Bitcoin developers, uses electrs in its block explorer, esplora, which is live at blockstream.info.

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.

Blockchain in the Public Sector – Webcast Q&A

Blockchain in the Public Sector – Webcast Q&A
Link to our website: https://block.co/blockchain-in-the-public-sector-webcast-qa/
Block.co fourth webcast titled "Digital Transformation of the Public Sector & The Upcoming Legislation of Blockchain Technology in Cyprus” was an immense success. We gathered some of the best experts in the field, Deputy Minister Kyriacos Kokkinos, Jeff Bandman, Steve Tendon, and Christiana Aristidou to share their experience and discuss with us the latest updates regarding Blockchain in the Public Sector.
In its fourth series of webcasts, Block.co gathered 281 people watching the event from 41 different countries, for a two-hour webcast where guests answered participants’ questions. Following the impressive outcome and response we received from the audience, Block.co’s team has done its best to address all the questions for which public information is available.
Below is a list of the questions that were made and were not answered due to time constraints during the webcast. For the remaining questions from our audience, the team will reach out to our distinguished guests to receive their comments and feedback. Please note, that the below information is only for informational purposes!
Question 1:
How can asset tracing be accomplished with bitcoins and cryptocurrency? And how can this be regulated?
Block.co Team Answer:
Digital Asset tracing may be accomplished with cryptocurrency intelligence solutions such as Cipher Trace and the ICE cryptocurrency intelligence program. FATF (Financial Action Task Force) embarked on a program of work from summer 2018 to June 2019 to strengthen and update the provisions dealing with virtual assets and virtual asset service providers. FATF updated Recommendations in October 2018 and Guidance in June 2019 include several new obligations that apply to VASPs. The so-called “Travel Rule” FATF announced in October 2019 agreed on the assessment criteria for how it will assess countries’ compliance with the new global standards. Under the Travel Rule, the transmitter’s financial institutions must include and send information in the transmittal order such as Information about the identity, name, address, and account number of the sender and its financial institution Information about the identity, name, address and account number of the recipient. The ”Travel Rule” is effectively being applied to cryptoasset transfers when there is a virtual asset service provider (VASP) involved. The scope of focus has broadened from “convertible” virtual assets to any virtual asset. Countries should make sure businesses can freeze crypto wallet or exchange accounts for sanctioned individuals.
Question 2:
Which kind of software or technical knowledge is required to develop cryptocurrency?
Block.co Team Answer:
It depends on the type of cryptocurrency you wish to create, as well as the preferred functionality and features, and characteristics of the token or coin (i.e. will it be pre-mined, what type of hashing or cryptographic algorithm will be used (i.e. proof of work (POW) or proof of stake (POS) or a hybrid of both), etc. Likewise, it is useful to utilize a programming language that is broadly used and supported by a vast and active development community; more data could be found here: more information could be found here: top programming languages in 2015/2016, published by IEEE here, and TIOBE. Hypothetically, you can utilize any programming language to make cryptocurrency digital money, however, the most widely recognized are C, C++, Java, Python, Perl. The beauty of cryptocurrencies is that you can literally have access to the entire Bitcoin and Ethereum open-source programming scripts, and create your alternate coin (altcoin).
Question 3:
Hello all, I want to know about the current status of the European Union Blockchain initiative in currency or public identity.
Block.co Team Answer:
Please refer to the European Services Blockchain Infrastructure (EBSI) website.
Question 4:
Mining is also the process of confirmation of transactions in the Bitcoin Blockchain. What is the process of confirmation of transactions in the Blockchain of an Organization? How do we call it?
Block.co Team Answer:
That would depend on the specific consensus algorithm used for the confirmation of transactions. The consensus algorithm is part of the blockchain protocol that defines the rules on how consensus is reached on that blockchain. In order to participate, entities on the blockchain must obey and follow the same consensus algorithm. Make sure to check our glossary for more information.
Question 5:
How does a small business implement blockchain into its current non-blockchain software systems? Who do they hire to install it?
Block.co Team Answer:
It is easy when there are APIs to connect the various software. For more information, you can check Block.co API.
Question 6:
What is your opinion on digitizing developing economies like India by using AI and blockchain?
Block.co Team Answer:
Watch a very interesting webinar on the matter by Mr. Prasanna:
Question 7:
Blockchain technologies have been around since 2008. What would you say has been the biggest obstacle in widespread adoption?
Block.co Team Answer:
In our opinion, the biggest obstacles are volatile cryptoasset prices, complicated UIs, undefined blockchain technology standards. Moreover, the legislation around the technologies is still now being developed and does not offer legal certainty for broader adoption.
Question 8:
Limitations to Blockchain Usability in the Public Sector?
Block.co Team Answer:
Blockchain in the Public Sector, like any other innovative concept with big potential, cannot be a solution to every problem. Users and developers are still figuring out technological and managerial challenges. From a technological perspective, some aspects such as platform scalability, validation methods, data standardization, and systems integration must still be addressed. From a managerial point of view, the questions include business model transformation, incentive structure, and transaction scale, and maturity. Read more here.
Question 9:
How can these blockchain initiatives be practical for the African context
Block.co Team Answer:
As long as the internet infrastructure is in place, these blockchain initiatives may have the same benefits for the African region.
Question 10:
What are some compelling use cases you’ve seen lately, and how do they serve to further legitimize blockchain as a solution?
Block.co Team Answer:
You can see the global trends from all around the world when it comes to further legitimization as a solution, with China leading the way. Read more here.
Question 11:
How does digital currency manage the issue of money laundering?
Block.co Team Answer:
Depends under which context you are looking at the term digital currency. A digital currency usually refers to a balance or a record stored in a distributed database, in an electronic computer database, within digital files or a stored-value card. Some examples of digital currencies are cryptocurrencies, virtual currencies, central bank digital currencies (CBDCs), and e-Cash. The Financial Action Task Force (FATF) is an intergovernmental body established in 1989 on the initiative of the G7 to develop policies to fight money laundering. Since 2001 FATF is also looking into terrorism financing. The objectives of FATF are to set standards and promote effective implementation of legal, regulatory and operational measures for combating money laundering, terrorist financing, and other related threats to the integrity of the international financial system. FATF is a “policy-making body” that works to generate the necessary political will to bring about national legislative and regulatory reforms in these areas. FATF monitors progress in implementing its Recommendations through “peer reviews” (“mutual evaluations”) of member countries. It is the global watchdog for anti-money laundering & counter-terrorist finance. In June 2019, it updated its guidance paper for Virtual Assets Service Providers (VASPs) regarding the transfer of digital assets. There was an insertion of a new interpretive note that sets out the application of the FATF Standards to virtual asset activities and service providers. To apply FATF Recommendations, countries should consider virtual assets as “property,” “proceeds,” “funds,” “funds or other assets,” or other “corresponding value.” Countries should apply the relevant measures under the FATF Recommendations to virtual assets and virtual asset service providers (VASPs). Read more about the FATF recommendations here).

Question 12:
To what extent can blockchain be used to improve the privacy of healthcare?
Block.co team Answer:
Please refer to our previous webcast, blog, and articles for more information.
Question 13:
What is Blockchain technology in Shipping?
Block.co team Answer:
The shipping sector has been in the hold of phony maritime institutes charging exorbitant fees via agents, issuing certificates to candidates who do not have the imperative attendance, or those candidates who just pay the fees for the course and ask for the certificate. In view of these fake accreditations, the possibility exists that someone could be harmed or killed, and we could face any number of potential ecological disasters. Having the option to easily verify the genuine origin of a certificate by an approved maritime center is foremost for shipping companies to fast-track their operation and streamline their labor.
Question 14:
Different uses of blockchain other than cryptocurrency?
Block.co team Answer:
Please refer to our blog and glossary.
Question 15:
Upcoming trends in Blockchain concerning Advertising, Marketing, and Public Relations in the Public and Private sectors.
Block.co Team Answer:
Regarding the application of blockchain technology to media copyrights, please see Block.co use case proposal during the Bloomen Ideathon.

Question 16:
How to create a decentralized blockchain?
Block.co Team Answer:
An excessive number of individuals feel that blockchain is some supernatural innovation that makes up a decentralized system. In truth, this innovation only enables decentralization. Which means, it permits cryptocurrency to work in a decentralized way. Yet, it doesn’t give any guarantees that it will work that way. Along these lines, it’s really, some outer variables that decide genuine decentralization. Technology, itself never really guarantees it. That is the reason it’s a mistake to expect that if it’s a blockchain — it’s decentralized. From a technical perspective, both blockchains, centralized, and decentralized are comparative, as they take work on distributed peer to peer to network. This implies every node is individually responsible to verify and store the shared ledger. Both Blockchains utilize either a proof-of-work or proof-of-stake mechanisms to make a solitary record and they have to give upper and lower limits on the security and productivity of the system. For more information please refer to our infographic.
Question 17:
Dubai government Blockchain implementation progress?
Block.co Team Answer:
You can see more information here.
Question 18:
How Blockchain and IoT can be integrated to secure data being transmitted through IoT devices.
Block.co Team Answer:
You can read more about it here.
Question 19:
How can the Nigerian government use Blockchain to effectively implement its existing launched eGovernment master plan?
Block.co Team Answer:
Perhaps it can draw its attention to the initiatives of Dubai, Estonia, and Malta to prepare an implementation framework.
Question 20:
What impact is blockchain going to have in today world of business especially in the financial sector
Block.co Team Answer:
Please refer to our recent article titled Benefits of Blockchain Technology in the Banking Industry.
Question 21:
Is Blockchain Technology affect individuals?
Block.co Team Answer:
The social effect of blockchain innovation has just started to be acknowledged and this may simply be a hint of something larger. Cryptocurrencies have raised questions over financial services through digital wallets, and while considering that there are in excess of 3,5 billion individuals on the planet today without access to banking, such a move is surely impactful. Maybe the move for cryptocurrencies will be simpler for developing nations than the process of fiat cash and credit cards. It is like the transformation that developing nations had with mobile phones. It was simpler to acquire mass amounts of mobile phones than to supply another infrastructure for landlines telephones. In addition to giving the underprivileged access to banking services, greater transparency could also raise the profile and effectiveness of charities working in developing countries that fall under corrupt or manipulative governments.
An expanded degree of trust in where the cash goes and whose advantages would without a doubt lead to expanded commitments and backing for the poor in parts of the world that are in urgent need of help. Blockchain technology is well placed to remove the possibility of vote-apparatus and the entirety of different negatives related to the current democratic procedure. Obviously, with new innovation, there are new obstacles and issues that will arise, yet the cycle goes on and those new issues will be comprehended with progressively modern arrangements. A decentralized record would give the entirety of the fundamental information to precisely record votes on an anonymous basis, and check the exactness and whether there had been any manipulation of the voting procedure.
Question 22:
As Andreas Antonopoulos often says in his MOOC: ”is a blockchain even needed?” Ie. Are there better methods?
Block.co Team Answer:
In combination with nascent technologies, IoT, distributed computing, and distributed ledger technologies, governments can provide inventive services and answers for the citizens and local municipalities. Blockchain can provide the component to create a safe framework to deal with these functions. In particular, it can provide a safe interoperable infrastructure that permits all smart city services and capacities to work past presently imagined levels. On the off chance that there were better techniques, they would be researched.
Question 23:
Would any of this be also applicable to the educational sector (as part of the general public sector), and if so in which way?
Block.co Team Answer:
Yes, please refer to our Webcast on Education and our blog post.
Question 24:
Will we be able to get a hold of this recording upon completion of the meeting?
Block.co Team Answer:
Yes, here is a link to the recording of our webcast Blockchain in the Public Sector.
Question 25:
Was wondering if there are any existing universal framework in governing the blockchain technology?
Block.co Team Answer:
The short answer is NO, as this framework is currently being prepared in collaboration with the various Member States.
