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 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.
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.
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
, 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: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
How it works & scales
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
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.
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 estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run 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...
- Download Dragonchain’s dctl
- Input three commands into a terminal
- Build an image
- Run it
More information can be found in our Get started documents.
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.
APIs (on chain & off)
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.
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
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.
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.
- Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
- 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).
- In a combination of the above, customers could cover aggregated fees.
- Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
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 Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
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.
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.
Public, third-party implementation review available or in progress
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.
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).
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
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. Original OSSRELASE-10 document
The Dragonchain Foundation was created on January 17, 2017. https://den.social/l/Dragonchain/24130078352e485d96d2125082151cf0/dragonchain-and-disney/
I've taken the liberty of rounding up all the questions and answers provided from Hydro's most recent AMA hosted with BitcoinMarkets incase you missed it. Enjoy! Hydro Q&A’s Q (knonsu):
How does Snowflake relate to other identity protocols out there like Civic and uPort ? A.1 (Anurag):
We see snowflake as existing a layer below these types of projects. Even without blockchain, identity is a broad term. Different people around the world have different forms of identity (state ID, country ID, social media IDs, etc). Civic, uPort, and other blockchain projects help to build specific types of an on-chain identity for a user; however those IDs are meaningful in different ways to different observers. For instance, imagine that a government or business builds a system that accepts Civic as a form of identity while another government/business only recognizes uPort identities. On top of this, certain systems only care about information tied to a user’s social media profile. A user can maintain one standard Snowflake as a base layer and set each of these different forms of identity as a resolver. Snowflake eliminates the need for global unanimous adoption of a singular identity standard and rather allows systems to build business logic off of identity standards they themselves recognize. Follow up Q (knonsu):
thats cool. so its totally depends on the person/ institute utilizing it . One problem I found is how easy its to create fake identities (in their basic system). A.2 (Anurag):
Yup! So people can conduct off-chain verifications to prove that you own a snowflake, and then tie an on-chain verification to your Snowflake. This links real-world KYC to your on-chain ID, so sure you could mint another snowflake, but that same party won't validate it again for you. Anyone who trusts that party would be able to accept their validations, and people who don't trust that party can rely on a different validator they do trust.
— Q (kat):
How big is the team working specifically on Hydro products? Can we get a numbers breakdown of engineers, biz dev, etc? Do you have plans to scale this team as the Hydro project develops? A.1 (Andy):
Our Hydro team is 8 people.
Devlopers (Myself and Noah)
Product (Anurag and Shane)
Founders (Mike and Matt)
The nice thing about Hydrogen though is we have a team of 30 people who we can leverage for different things. For example, Noah and I do not build mobile apps, but we have a front end team that is well versed in mobile app development. So while they are not directly on the Hydro team they do have a direct impact on Hydro.
Hydrogen as a company is working to grow pretty rapidly. As we grow we will be filling out more positions in both blockchain and non-blockchain rolls. A.2 (Anurag):
To add to Andy's answer - pretty much everyone working for Hydrogen helps out with Hydro in some way, whether via design, front-end development, API support, business discussion, etc.
Here's our full team: https://www.hydrogenplatform.com/about
— Q (rocket man):
So in the age of ICOs, what motivated your team to not pursue that funding model and instead have a token distribution for developers? A (Andy):
This was something that we spent a very long time considering and discussing. We spent a lot of resources (time, money & energy) trying to find the best solution for us going forward. When it was all said and done, we decided on an airdrop because of two main things, getting the token into the hands of people who will actually use it and regulatory concerns.
We feel as though our distribution was the fairest approach that allowed for people with actual interest in the Hydro community to get involved. Overall, we have been very pleased with the level of community engagement from people who are interested in the utility of the Hydro token and we feel that a lot of this can be credited to our distribution strategy.
— Q (matheussiq8):
How hydro tokens will be used is still vague in the Snowflake whitepaper draft. Would the amount required to hold depend on the volume of API calls or some other parameter? For example, if I decide to implement raindrop and later snowflake in my small webshop would I need to hold the same amount of tokens as Binance (if they ever implement it of course…)? A (Noah):
as always, the permissionlessness of public blockchains is a double-edged sword. smart contracts partially solve the problem by letting us enforce certain things on-chain (minimum token balances, signature validity, etc.), but there are limits. so, re. your specific question: in raindrop we do not vary the staking requirement across users, because that would necessarily involve value judgements we are not comfortable making as a centralized entity. however, there are two types of staking required for raindrop:
- “institutional staking” requires entities who wish to sign up raindrop users *on their behalf* (i.e. passing new users’ addresses to the smart contract as parameters rather than new users transacting directly from their accounts) to stake a significant amount of hydro. these are the players we want to ensure are acting in the best interests of the community. in this model, hydro is simply one of many institutional stakers (where we sign up users on our kickass mobile app, which will be out soon).
- “user staking” requires individuals who wish to sign up for raindrop on their own, i.e. transact directly with the smart contract, are able to do so by staking a much smaller amount of hydro.
What this all means for you, as a potential customer of our API, is that you don’t actually have to worry about the staking requirement or signing up users at all, and can simply use our API in conjunction with the Hydro app.
Looking ahead to Snowflake, we have big plans to integrate increasing sophisticated uses of the token into the product. to some extent these are still up in the air, but rest assured that we are very focused on building a strong tokenomics structure. At a high level, the core token mechanism for snowflake will involve depositing tokens into the snowflake smart contract. These deposits will allow native staking/payment/incentive functionality denominated in hydro, without the hassle and worry of using ether with every call.
— Q (Hodlall):
When is raindrop Android app is releasing A (Andy):
It is currently under development. We have a bunch of android phones with different OS on the way. It is hard to give a set date as we don't know what unforeseen issues could come up during the process though. All I can say is it is literally all that our mobile development team is working on
— Q (Jeff_We_Cannafi):
To piggyback on matheussiq8’s question, how do these identity tokens compare to existing forms of identity authentication, and do you anticipate the tokens themselves will be traded on exchanges? A (Andy):
In my opinion, the main difference between what we are working towards and others like civic and uport is the scope of what we are aiming to do. We understand the value of having KYC on the blockchain and "One click signup", but really I think blockchain identity can be so much more than that. We are aiming to create a completely extendable and modular protocol which will allow for people to link anything they desire to their blockchain identity. Other protocols can tend to lean towards centralization (more a fault of current KYC procedures than the projects themselves) and we feel like this doesn't have to be the case. At least for now, something like KYC needs to have central authorities to verify user information, but why can't I also link my crypto kitties to my blockchain id or my linkedin profile to my blockchain id?
Overall, what we are trying to build will easily allow for other blockchain developers to create robust identity solutions for whatever application they feel fit with Snowflake being at the core of that. We feel that this is crucial to eventually creating a completely open and decentralized identity system. Anyone can join and anyone can add what THEY consider to be an identity, but I only have to accept what I consider to be an identity.
As far as trading, Snowflake Identity tokens will never be tradable. We feel that you identity should always be linked to you. This would be a dangerous road to a very easy black market for people's identities
— Q (Jrock):
What do you find the hardest part of pitching icos to regular companies?
Also what do you think needs to happen for widespread crypto adoption? A (Shane):
If you mean pitching Hydro to regular companies (we're not an ICO :stuck_out_tongue:), I would say the hardest part is getting the larger companies to move faster than a snail's pace. There are too many chefs in the kitchen and sometimes there is a lack of top-down strategy on blockchain, and it leaves large enterprises paralyzed sometimes. We try to resolve this by pitching how easy Hydro is to use, and how it connects to our broader Hydrogen ecosystem which can add value in a lot of places.
In my opinion, widespread crypto adoption is going to be dependent on how parallelization plays out. If crypto's only option is to create a new parallel economy, widespread adoption is going to be slow and arduous and will take decades. However, if blockchain is able to be infused or layered on some of the current systems we have in place, the adoption will be much faster and broader. Ultimately this comes down to the usage of private vs public chains - the more private and centralized chains that get implemented, the farther the mainstream adoption will get pushed out.
— Q (Luke):
One aspect of Hydro that is beginning to really intrigue me are the potential use cases and dapps that can be built by external developers ontop of the Hydro protocol layers for each phase.
- Having held various dev meetups and networking at various conferences, how are you finding the process of attracting developers to start building dapps and products in your ecosystem?
- I understand the HCDP is getting updated with various new rules and bounties for dapps to be built, have you approached any developers yet with this new offer, and if so, how has the reception been?
- How else do you intend to attract developers towards building on the Hydro protocols?
- Through our events, we're mainly focused on helping expand the blockchain-focused developer community. We help give exposure to projects we find to be doing neat, innovative work in the space and keep ongoing dialogue with these communities.
- In particular, to provide impetus to developers in the Hydro ecosystem, we've established the HCDP. The new process will involve putting out specific task requests. In the next week or so we'll have published specifications for dApps that can be built on top of Snowflake. We ourselves will not be building these dApps (they have nothing to do with Hydrogen's space as a company). This helps the ecosystem expand outside of Hydrogen-specific use-cases.
- ^^Through the above process to get them started. Eventually, we want the Hydro development process to be community-driven, so people are building on Hydro because it benefits their own programs and applications.
— Q (elmer_FUD):
Hey Hydro Team! Here's a few question I've got for you after checking out the Raindrop and Snowflake whitepapers:
How has your experience working in the Ethereum ecosystem been so far?
While you are currently focused on the financial sector, would you consider actively marketing to other sectors such as healthcare and education in the future?
It seems like both Raindrop and Snowflake would be useful in any environment that processes or stores sensitive data.
Do you have plans to release official Raindrop SDK packages in other languages in the future?
A bit more of a specific question: Raindrop is looks like a great product to use in a PCI-DSS environment - do you have thoughts on whether or not it the product is ready for primetime and do you think the industry standards and government regulation is prepared to handle these kinds of systems? A (Andy):
Thanks for the questions! I'm gonna answer each in a separate response in this thread
Overall it has been pretty solid. There is still a ton of room for growth in terms of documentation and stuff like that, but it is miles ahead of basically every other blockchain platform I have worked with. By far the biggest pain has been handling gas costs when considering the user experience. When trying to build actual products that people will want to use we feel that making it user friendly is something that many blockchain projects have not focused on nearly enough.
Yeah certainly. We focus on fintech as that is where the rest of our companies APIs focus and that is where we have the most connections, but much of what we are building is much further reaching than that. Just as far as authentication goes, it really can apply to any major field and we intend to market it as such.
We currently have Python and JS SDKs and have had a few java ones submitted through our community dev program. We have been revamping that program, but I anticipate we will be putting up more bounties for most major languages. I have considered making a few more myself, but we feel that they could be better suited as community projects.
I completely agree. Raindrop and blockchain authentication when handling anything around payments is a great application. I think the biggest thing is actually convincing regulatory bodies that the protocols we have build are secure (since many can still be scared of blockchain). I definitely see this as a direct use case though
— Q.1 (khonsu):
What kind of banking relations do you have as a company, do they (banks) understand what you are trying to do ? Any VCs approached you for funding ? explain your business model. A.1 (Shane):
Hydrogen has existed since 2009 in the form of Hedgeable. Hedgeable is a consumer-facing online investing app, and the tech behind it eventually spawned the Hydrogen tech platform. The story of how the transition happened goes essentially like this: (1) Hedgeable was disrupting banks & investing firms, (2) banks & investing firms started contacting us and seeing if we would help them digitize & automate their own businesses, (3) we started packaging up our tech and selling it to the banks. There was so much demand for this from financial institutions that we spun out a new company (Hydrogen).
So to get back to your original question: we have some long-standing relationships in the banking & finance world, and to this day we have inbound leads from that space coming in every week. The key thing to keep in mind is that these institutions move extremely slowly, but they do understand the core value prop of our platform. Many of these firms are still in the midst of basic digitization efforts (i.e. moving from really slow offline processes to simple digital infrastructure), and that is the primary thing we are helping them with in early stages. But they are also keen on blockchain tech and they will naturally turn to us for that once they reach that point. We do have a few relationships with big financial companies in which Hydro/blockchain are already part of the discussion.
We have revenue and don't need to rely on VCs. It is our general philosophy that building a business sustainably with actual clients and revenue is a good approach, but we would consider working with the right VC if that came to be and we wanted to scale more quickly. Right now, that is not an immediate concern for us.
Our business model is in charging developers and enterprises to access the Hydrogen technology platform, which currently consists of products like Atom, Ion, and Hydro. Developers pay a per-user fee to hit our core APIs, while large enterprises negotiate custom (usually multi-year) contracts with us that typically include recurring revenue. Hydro, specifically, is being offered for free right now, as we attempt to gain adoption. But it is important to note that Hydro is just one piece of our ecosystem. Q.2 (Joleen):
When you say fee - is this fee HYDRO? And when do you envisage HYDRO to no longer be offered FOC? A
**.2 (Shane):** Sorry if it wasn't clear, I meant free to use our Hydro tech/APIs. The usage of HYDRO tokens within that is a separate issue - they still need to have HYDRO and we do not give it away for free to clients
— Q (guacam0le):
Adoption of an identity management solution (etc) would potentially involve a lot of identities. Further, scalability is a hot topic w/ blockchain. Is this a potential bottleneck? What is or might be done to address such?
Tackling a competitor like Google or Authy's 2FA is no small feat. Also, not everyone is yet to embrace blockchain-based solutions. Have you found it difficult to interface with enterprises & get them excited about the idea of an overhaul? A (Anurag):
nowflake is designed to be relatively low-load on the blockchain. A user needs to conduct a single transaction to “mint” their Snowflake. Once this is complete, they would need to complete one-time transactions to set each of their different forms of identities as resolvers as needed. A Snowflake is designed to be built out via resolvers over the duration of a user’s lifetime, so there’s never a need for heavy, frequent transactional capability. Similarly, smart contracts simply need to be set as resolvers by users; they do not themselves transact. Network scalability improvements will increase the range of use-cases for smart contracts that can be tied to Snowflake, but they aren’t a necessary prerequisite to some important early use-cases such as KYC platforms, and a few basic user-interaction platforms.
As far as competition, we feel that current adoption of 2FA is, in general far short of where it should be, and any 2FA is generally better than none. Many businesses use text-message based 2FA, etc. In the short-run we are aiming toward pilot implementations with small businesses. To further this, we have put out many integration resources, guides, and documentation and accordingly believe implementation of Raindrop is a more straightforward workflow. As far as large enterprises go, Hydrogen has clients, so it is helpful for our project to have those connections. Large institutions are generally relatively slow-moving, but have expressed interest in using Raindrop, in particular for securing employee accounts. As the product grows, we may eventually move in this direction with Client Raindrop, but resources will always be available for any site that wants to adopt it. Additionally, we are looking into making a wordpress plug-in to make implementation much more accessible for many developers.
-- Q (Smithymethods):
I know Hydro is a fintech company, hydro plan to curb phishing and hacking to the bearest minimum we know that hacking is very rampant these days on MEW and with other wallet. Is Hydro planning to create a wallet that support hydro and other tokens using their raindrop Technology?
As this will put an end to the problem of phishing and also promote hydro A (Noah):
like everyone in the crypto space, we’re very worried about phishing, both personally and on behalf of all hydro token holders. we first want to reemphasize that preventing scams and fraud has to be a community-driven effort: teams and users need to be vigilant and promote best practices (never trusting links in public chats, shunning fake accounts, etc.). we are excited about raindrop’s potential to help combat phishing, though. we actually talked with someone about mycrypto about integrating raindrop into their desktop app. we’ve forked their code and are researching how feasible an implementation would be, stay tuned for updates!
— Q (Hodlall):
What security measures in place for hydro , I see lot of tokens being hacked nowadays , and money is stolen.. how does hydro make sure their team tokens are completely secured or as much as possible A (Andy):
We all have been in crypto for a while and are pretty well versed in securing our stuff. Our tokens that are currently locked are in cold storage. Others are held in hardware wallets
— Q (Joleen):
We know that the Hydrogen platform is going to be used by CI Investments, a large insurance firm and a world top 20 bank, have these companies already begun purchasing Hydro OTC? A (Andy):
This is something that we feel is best to be hands off with. It is really up to the discretion of our partners
— Q (khonsu’s mumaffi):
Ill be honest i have not yet fully read the whitepaper but id like to know other than investor growth do you truly believe there is interest in a model where users have to pay each time for access? How big do u expect this fee to be...for large companies dont you believe this is an unscalable practice? This may be a question more about most technologies built on token based economics too. A (Andy):
So we have 2 different authentication protocols. One happens less often and is in the same vein as OAuth. This is called Server-Side Raindrop. This requires tokens to be sent. This protocol would only happen once per day for a business when accessing something like an API. I don't feel that these values are extremely high for increased security.
Our second protocol, Client-Side Raindrop, functions much more like google auth. This logic actually does not require any tokens or even a transaction by the end user. It is 100% free for them to use and they will never have to pay for a transaction. Here the responsibility is on the implementing party to stake tokens. This allows them to onboard users and authenticate them.
We felt it was crucial to have an authentication that did not have a cost per user login as it is not scalable
— Q (khonsu’s mumaffi):
Also do u plan to tokenise atom and ion too and if not covered earlier how big of an impact do the market conditions have on your business A (Anurag):
Tough to say we're going to "tokenize" them since that word can carry a lot of different meanings in different contexts, but we do plan on integrating the entire Hydrogen platform with Hydro. This will most likely take the form of enhancements to systems leveraging Hydro. You can find a more detailed breakdown on our Hydro roadmap: https://medium.com/hydrogen-api/project-hydro-features-in-depth-look-39faa29f0d61
Market conditions don't really have an impact - we're still building the same tech on a day-to-day basis
— Q (ghost):
As a company in the space, do you see the fact that tokens have to be acquired on exchanges as an issue? How would a company that wants to develop with you acquire tokens? A (Anurag):
Depends on what they're developing. dApps developing using Hydro smart contracts to create native functionality to their applications would need to acquire those tokens on their own; however, companies using the Hydrogen API will not. Here's a detailed article outlining when a developer would need the token for the Client Raindrop smart contract: https://medium.com/hydrogen-api/how-to-use-client-raindrop-without-using-the-hydrogen-api-bb04934ae293
— Q (jarederaj):
Can you describe your stakeholders and give me a better sense of the exigency of your products? Who are you focused on serving with your platform and why are they motivated to use your platform? A (Shane):
The Hydrogen platform serves developers and enterprises who want to build applications. We are specifically targeting the financial services sector, including banks, investing firms, insurance providers, and financial advisors. This includes large enterprises, individual developers, and startups.
Our products are Atom (core digital infrastructure & engine for finserv), Ion (AutoML & business intelligence capabilities), and Hydro (blockchain & decentralization layer). Each has a different use case but these products combine to form an ecosystem of tools for developers to build sophisticated applications with.
The main pain point we are addressing is the resources required to build, launch, and run a digital financial application. These resources include both time and money.
Large enterprises have resources, but they waste years and millions of dollars trying to launch digital platforms (we've seen this first-hand), often unsuccessfully. The motivation here is obvious. Startups and smaller developers, on the other hand, do not have access to huge resource pools, so they are forced to look for solutions that make the process more efficient.
In the same way that Wordpress makes launching a blog easy and also allows for extended functionality, Hydrogen makes launching fintech application easy.
— Q (shujjishah):
When the app will be released??? A (Anurag):
We're going through our mobile development very iteratively. Since we work very closely with the product, there are things we can't recognize until we've got people beta testing the app. As we started Beta testing and conducting user-research, we realized that one aspect of the UI for the app was not intuitive to about half of our testers. We decided to make a few API changes to enable the mobile app to display a "linked" vs "unlinked" status in order to improve the user experience. Our front-end team is finalizing these changes, so our Beta testers will receive a new build in their testflight apps within the next few days. This new build will require another round of Beta testing to ensure that none of the code changes causes any problems on devices; if this change goes smoothly, and our mainnet testing goes smoothly, we will be able to release the app this month.
Since there isn't much precedent on releasing a product into the app store that connects users with the ethereum mainnet, our primary concern is making sure the product works fully as intended and provides an intuitive user experience. Misc Q&A’s Q (elmer_FUD):

Who's got the best banter in the office? And who has the worst? A.1 (Andy):
One of our backend devs, Paavan, typically has some great banter
and even better hot takes A.2 (Noah):
dont @ me for worst banter A.3 (Shane):
Sabih (BA @ Hydrogen) banter is by far the best
