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.

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.

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.

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

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.

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:

• Den social media
• Eternal & Save The Tweet bot
• Lyceum/Academy

​

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.

​

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.

• TIME
• Learn more about TIME and how to apply this to your nodes

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.

Dragonchain Foundation

The Dragonchain Foundation was created on January 17, 2017. https://den.social/l/Dragonchain/24130078352e485d96d2125082151cf0/dragonchain-and-disney/

Recently, BCH has reported a hard fork again, which surprised all coin lovers: again, will the current bull market end? It is reported that the new fork chain code is BCC, which was initiated by ViaBTC mining pool CEO Yang Haipo. On August 5, 2020, Yang Haipo released a Weibo stating: “BCH has been suffering from ABC for a long time, and it is time to make changes.”
In August 2017, due to the inability to mediate conflicts between Bitcoin core developers and big miners at that time, Bitcoin had its first fork, and BCH was forked from Bitcoin with the strong support of Bitmain.
At that time, many people looked to BCH because it had a more reasonable expansion plan and strong support from a group of miners, and was considered to be able to become a real Bitcoin. However, after a brief period of hustle and bustle after the fork, the industry no longer argues about who is the real Bitcoin — -Bitcoin is still Bitcoin, and BCH is habitually called the “Prince”.
Just a year after the BCH forked, the BCH system put forward more radical expansion ideas due to “Craig Wright”, which made the “Craig Wright” and the other faction led by Bitmain also have irreconcilable contradictions. Causes BCH to fork. In November 2018, BSV forked from BCH.
Since the fork, BSV has performed fairly well in terms of currency prices, but in the “short gate” that was raging at the time, many people were swearing “Craig Wright”. The dispute between BSV and ABC not only pulled the price of BCH from the “Prince” throne, but also suspected that “‘Craig Wright’ joined forces with’Wu Jihan’ to maliciously short BTC”, resulting in BTC being smashed sideways for half a year The price of 6000 in the support range fell to 3100 US dollars, causing heavy losses and loss of faith for many coin players.
The hot discussion about the re-fork of BCH makes everyone worry that the Bitcoin bull market will be affected, but many people are also concerned about whether similar things will happen to the global basic public chain DEMOS in the future? It is hard to say whether DEMOS will fork in the future, but there will certainly not be fork problems like Bitcoin.
The reason is: First of all, the DEMOS community is 100% autonomous, and any proposal is subject to voting. This voting system is called DEMOS Convention Center, or DCC for short.
Secondly, even if DEMOS forks, it will not cause disputes in computing power like BCH or Segwit2x, which will adversely affect currency prices. On DEMOS, the new blocks generated by POW miners need to be consistent with the wishes of DEMOS shareholders (POS miners). If POW miners refuse to comply with the collective policy, then POS shareholders can determine that the new block is invalid. For example, if 80% of shareholders support the fork and 20% of shareholders refuse, then these 80% of shareholders can invalidate new blocks on the old chain through DCC. In this way, POW miners will directly transfer from the old chain to the new chain, and the old chain will be invalid.
DCC well protects the uniqueness of the DEMOS main chain, and this design is not only suitable for DEMOS, but also for all basic public chains that DEMOS will play in the future. The traditional public chain is very helpless with the hard fork problem. In order to maintain its own advancement and rationality, it has to make a fork behavior at some point, but this is equivalent to the loss of users for an application-oriented public chain. The adverse effects caused are long-term, and DEMOS’s DCC mechanism can avoid the loss of users to the greatest extent.
Although some people think that the probability of this fork of BCH is not great, the problems that existed at the beginning of its design cannot avoid the occurrence of similar fork events in the future. The original idea of DEMOS is to help all basic public chains solve problems that they cannot solve by themselves. I believe that with the development of DEMOS, it will be able to help public chains such as BCH to solve these problems one day in the future, and that will be the day everyone hopes to return.

Bitcoin system
Would you imagine the Bitcoin and other cryptocurrencies are all set to increase very steeply back again? In 2010, since commencement, Bitcoin has been the very first electronic advantage to generate a whole network of cryptocurrencies. There came a time where it escalated an undercover after investors that looked very enthusiastic about its own future as a potential substitute for the physiological economic system, as conventional institutional members strangely saw its own development.

​
While we’re still there is a possibility for a long time off from an entire transition, then the crypto distance was a reasonably explosive field. Throughout the rise and adoption of crypto, many individuals have started ICOs (Personal Coin Offerings, relative to providing brand new assets) with no omission or control. With that, Bitcoin directed the fee to an evaluation of approximately 20,000 dollars percentage in 2017, although it’s worth steadily decreased over the course from 2018 and remained at the assortment of 3,500 to 4,000 dollars for quite a while.
​
However, modern action has generated Bitcoin’s significance to rise and it has captured the interest of many existing and prospective investors.
​
Recently, for several years, the crypto marketplace has grown with more regulatory and oversight directions in position by both federations and state bureaus. More groups and individuals are currently seeking approaches and techniques to lessen their risk while securing a beneficial ROI as a consequence of those measures and much more institutional dollars encouraging the business. Except you were living beneath a stone for the last half a decade, you’re probably more than conscious of this happening of Bitcoin. However, what really is it and can it replace normal money as a way of trading?

Here we simply take a glance in Bitcoin and research its prospective future as an alternative to monies or being an investment medium or even both. We are also introducing the Bitcoin system and its features. We will discuss how well Bitcoin system can perform and why it is our best pick when it comes to online trading. This is a comprehensive Bitcoin system review and other trading know how
Bitcoin system Review
Bitcoin system is an online cryptocurrency trading platform. Bitcoin system is one of the leading and top performing trading system in the crypto market. Upon reading numerous Bitcoin system review, we really thought to make an actual testing in it. So from Bitcoin system’s website, to Bitcoin system registration and capital deposits, to Bitcoin system free demo trading, and to Bitcoin system live trading, we dig deeper in examining the whole process. And guess what? It is not that very complex, not at all! With that, we realized that this Bitcoin system platform can be accessed by individuals who are just learning and just starting their trading ventures in crypto market.
​
Bitcoin system has a simple interface, simple setting, understandable Bitcoin system demo trading. Bitcoin system does not charge any additional fee. Many Bitcoin system users have stated their reviews on the actual website. Bitcoin system fraud has never happened in the history of this platform, they have experts who are working every day to guarantee everyone’s safety and protection from online attacks.
Cryptocurrencies are like Bitcoin, they are electronic cash which is not endorsed by real resources or real securities. Cryptocurrencies are exchanged through both agreeing parties without an agent and monitored to digital records.

Individuals like you who are interested in cryptocurrency investment should execute a substantial quantity of research into what cryptocurrency you decided to put money into, exactly like every stock, up until buying.
Cryptocurrencies have become so popular, capturing even the attention of prominent people and also have generated a huge amount of money for a huge number of individuals. The latest boom of BTC or Bitcoin now usually implies that if you’d spent just 500 dollars from 8 years past, you’d be a multi-millionaire today. How interesting, right? People who took risks back then are now in the most amazing time of their lives. This swift increase in the vastest cryptocurrency through market cap has attracted a vast range of awareness. But to the regular person who’s accustomed to coping with income and actual price, cryptocurrencies can look to be an unfamiliar and a meaningless aspect. With respect to such as data mining, exchange capitalization, and the fear of uncertainty, there exists a tiny bit of an ill-natured learning hook for technology.

DEMOS
DEMOS, in line with the fundamentalism of Bitcoin, a unique and innovative new way of mining.
Under 10 years’ blockchain development, except for the innovation and popularization of blockchain technology, it is similar to rights such as decentralization until now. As the core of the blockchain, it can be said that the real sense of participation is very low, which causes thoughts on this question. When thinking about this issue, many friends in the digital currency circle also resonated, and they all want to explore a project that can truly participate in decentralization. Let’s talk about the DEOMS project. The introduction of the white paper is called The Democratic Chain, as its name suggests: the democratic chain is truly democratic, fair, notarized, and open. The characteristics of decentralization are also reflected in DEOMS. Let's see how DEMOS is implemented?
What is DEMOS?
According to the white paper, DEMOS is a project initiated by the "crypto city" and has made many changes to the Bitcoin network in order to make the entire network more stable and secure. At the same time, it has a cryptopunk spirit, and the core of the cryptopunk spirit is decentralization. DEMOS comes from ancient Greek, meaning democracy, and also means collective. DEMOS is mainly to provide help for more and more public chains. In the process of helping, they gather public chains.
The main body of DEMOS is composed of a basic chain and an extended chain. Its shape is similar to the double helix structure of DNA, and it is a cross-checked structure without an array of symmetric data cross-recording. While taking into performance and security, DEMOS has achieved complete decentralization.
Double Chain Parallel
DEMOS uses dual public chains in parallel, and the dual public chains are the first in the blockchain industry.
Basic chain: The POW+POS hybrid mechanism is adopted. This hybrid mechanism is easy to understand. The proof of POW workload is recognized as safe and adaptable, and the proof of POS rights and interests is the representative of efficiency. Therefore, DEMOS has the advantage of taking into account both safety and effectiveness. DEMOS has made innovations in the hybrid mechanism for block time, node rewards and punishments, and encryption algorithms.
Expansion chain: Using the new POW+POB consensus mechanism, the POW+POB mechanism can be understood as the pre-work proof, that is to say, you must prove your ability to work in this area if you want to participate in this work. Working principle: Miners are divided into three types, namely: test list, black list, and white list. In the early stage, DEMOS will continuously provide the packaged data to the test list. Miners who meet the requirement of link time greater than one will be whitelisted, and those who fail to meet the requirements will be included in the blacklist. When selecting the packaging node, the whitelisted node will be selected as the packaging work. The expansion chain is mainly responsible for the expansion applications such as DAPP, and the main considerations are the network environment and hard disk capacity.
Innovative Mining Method
DEMOS mining is at different stages, the distribution of tokens is different, and it is currently in the creation stage of the bonus period of mining.
The first stage: the Era of Creation
Token distribution: 89% belong to the POS sector, 1% belong to the POW sector, and 10% belong to the community.
Phase Two: Age of Ark
Token distribution: 60% belong to the POW sector, 30% belong to the POS sector, and 10% belong to the community.
Participating in DEMOS mining in the first stage belongs to POS mining. It does not require a complicated process and only needs a mobile phone to complete, but the mining method of DEMOS is very innovative. This innovative way is also an evolution of the future of decentralization.
Parameters in DEMOS are as follows:
Participation conditions: have tickets, and join the mining pool.
Mining pool limit: unlimited mining pools, only the top 11 mining pools can draw points, and the fixed draw point is 7.5%.
P.S. Implement the final elimination system
Total number of votes: There is no upper limit on the number of votes. The most mature on the entire network is: 40,960 tickets. The tickets will be published on the chain.
Ticket price: Using DOS (DEMOS token) to buy a ticket, currently 1 ticket = 327.72DOS
Fare changes: once every 144 blocks
The difference between votes: mature votes (the votes currently participating in the election) and immature votes (the votes currently in line for the election)
Purpose of tickets: 1. DEMOS issues a block every 5 minutes, and each block needs to consume 5 tickets. Five tickets are randomly selected from the mature votes, and a burst of blocks also means a burst of votes. 2. The community proposes an autonomous plan, which needs to be voted through.
Ticket revenue: 1. Every time the DOS in a block is broken, the 5 votes are equally divided, of which 7.5% is drawn from the mining pool. The selected ticket is the principal plus the block income at the same time (there is no meaning of mining DEFI). 2. 30% of the revenue from each ticket will be given out as a referral miner reward, and each ticket held will get one layer for a total of 9 layers. Specifically: 25% for the first floor, 15% for the second to third floors, 10% for the fourth to sixth floors, and 5% for the seventh to ninth floors.
It can be seen from the DEMOS mining rules: First of all, the profit of the mining pool is open and transparent, with a fixed sampling point of 7.5%, and through understanding, it needs 1BTC and 30,000 DOS to build a mining pool. Interestingly, after your mining pool is set up, you have to wait for the miners to participate and take a fixed draw point.Unfortunately, the next mining pool will replace you, so the fate of the mining pool is determined by the miners’ votes. This is the mining pool in DEMOS which create a competitive relationship.
At the same time, you have the votes and participated in the major autonomy proposals of the community to truly achieve centralized autonomy. At the same time, the votes also strengthen your sense of enthusiasm in participating in decentralized projects. Such a decentralized and autonomous project is very much in line with Bitcoin's fundamentalism, and its innovative mining method also adds a lot of space to the future currency value of DEMOS.
