Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

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

Hello Reddit and Ethereum community!

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

Executive summary

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

Response and PoC

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

Live Demo

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

Source Code

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

Scaling

How it works & scales

Architectural Scaling

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

Economic Scaling

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

Scaled Deployment

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

Flexibility in Scaling

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

Cost

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

Getting Started

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

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

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

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

Costs and resources

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

Requirements

Scaling

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

Decentralization

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

Usability Scaling solutions should have a simple end user experience.

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

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

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

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

Bonus Points

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

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

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

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

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

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

Bonus

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

TIME

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

Dragon Den

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

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

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

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

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

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

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

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

Other Considerations

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

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

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

Conclusion

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

Disney Releases Blockchain Platform as Open Source

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

Open Source

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

RESEARCH REPORT ABOUT ARYACOIN

RESEARCH REPORT ABOUT ARYACOIN
Author: Gamals Ahmed, CoinEx Business Ambassador

https://preview.redd.it/a7jv4azk86u51.jpg?width=1600&format=pjpg&auto=webp&s=e4a4dbb5afacd5747076beaa59e6343b805c3392

ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

1.1 OVERVIEW ABOUT ARYACOIN

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

1.1.4 BENEFITS OF USING ARYACOIN

1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
5. Business Partner with Simplex
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies.

The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.

1.1.8 HOW DOES ARYACOIN WORK?

Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.

2. ARYACOIN TECHNOLOGY

2.1 PROOF-OF-WORK

They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past
block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.

2.2 NETWORK

The steps to run the network are as follows:
  • New transactions are broadcast to all nodes.
  • Each node collects new transactions into a block.
  • Each node works on finding a difficult proof-of-work for its block.
  • When a node finds a proof-of-work, it broadcasts the block to all nodes.
  • Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.

2.3 AYAPAY PAYMENT SERVICES GATEWAY:

According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world.
This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee.
In other similar systems or even systems such as PayPal, money is stored in the user account.

2.4 CONSENSUS ALGORITHM IN ARYACOIN

The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.

2.5 DOUBLE-SPEND PROBLEM AND SOLUTION

One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore
be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

Hey guys, as we know that from couple of some year people trying to bring all their investing money and goods to the Internet world.traders and investor, investor,buyer, and seller now his idea to invest,buy and sell online. People adopt the crypto currency,when bitcoin pumps in 2017. Since the introduction of bitcoin, cryptos have received considerable media attention worldwide, fuelled by the sharp appreciation of major cryptocurrencies like bitcoin compared to regular currencies, and the fluctuations therein, the close links they have with the shadow economy. Now every company have an idea to release their own token.some countries has also release their crypto coins. So many crypto exchanges has been discovered where people can trade and exchange their coins. But still there is some drawback in these exchange like slow transaction system, not secure at all, high fee. So today i am introducing you a very great decentralized platform called Draken in short DRK which fulfill all the cypto exchange requirement with their great features.
Introduction to DRK: DRK is world best decentralized system which combines all previous blockchain technology to one place by using a separate protocol retaining the key element of DEX. The main goal of the DRK platform is to provide secure system,low fee,fast transaction system and to combine all dex technology to one place (drakon group system.
Why DRK? As we know that decentralize system is one of the beat system in block chain with its some enhanced features but still needed some attention because External Factors,High Cost of operation, Problems of Coordination Are some disadvantages which need some improvement. So DRK decentralized system bring some advance feature to fulfill all these drawbacks.DRK has low fee,very high performance to allow thousand of transactions in seconds,cross chain and experience control. These feature allow investor to invest freely without any risk trading. These are some advantage this why i refer every online investor to invest secure in DRK.
Some advance featurea of Drakon: Low Fee: Every single trader want that he trade with no or little fee.but fee of the exchanges is so high.and very worst point is that you have yo pay fee in eth or btc which is so hard for users if they have only one token reward.here is some fee margin of big exchanges Bybit TAKER 0.075% MAKER -0.025% WITHDRAWAL 0.0005
Kucoin TAKER 0.10% MAKER 0.10% WITHDRAWAL 0.0004 btc
Binance TAKER 0.10% MAKER 0.10% WITHDRAWAL 0.0004 B
Fee of DRK Dex is almost nothing.you to pay only exchange fee of the coin which you want to trade it. DRK decided to prioritize user interest,as a result fee fee will be minimized.in this way maintain system great.
Transaction limit. Transaction speed of etherium network is very slow as it can only process 15-20 transaction/second. DRK provided facilities that every second 1 thousand transaction can be processed instant with DRK chain mainnet.
Cross chain: Almost all dex platform chooses etherium network but etherium network list only exist token. DRK have a modern own protocol which communication it with other block chain ,there every new token can be added here.
These are the main features which used by DRK platform to grow community great.
DRK Gaming: This is big entertainment for user,DRK provided a gaming zone for user name DrakinX where user make lot of money by just gaming. Gaming system is so good,there are two type of option 1: manual 2: AI trading There are 4 type of coin which you can stake 1: DRK. 2: ETH 3: dBtc 4: vbtc In " manual " you have a 20 second to buy+50+100 + 1000 or + 5000 and then an aero will go upward for leverege and will be busted at any leverage x,as you can see in picture.

[Part 1] KAVA Historical AMA Tracker! (Questions & Answers)

ATTN: These AMA questions are from Autumn 2019 - before the official launch of the Kava Mainnet, and it's fungible Kava Token.
These questions may no longer be relevant to the current Kava landscape, however, they do provide important historical background on the early origins of Kava Labs.
Please note, that there are several repeat questions/answers.

Q1:

Kava is a decentralized DEFI project, why did you implement the countries restrictions to run the node? Will there be such restrictions by the time of the mainnet?

Q2:

According to the project description it has been indicated that staking reward (in KAVA tokens) varies from 3 to 20% per annum. But how will you fight with inflation?

We all know how altcoins prices are falling, and their bottom is not visible. And in fact, we can get an increase in the number of tokens for staking, but not an increase in the price of the token itself and become a long-term investor.

  • Answer: Kava is both inflationary with block rewards, but deflationary when we burn CDP fees. Only stakers who bond their Kava receive inflationary rewards - users and traders on exchanges do not get this. In this way, rewards are inflated, but given to stakers and removed value from the traders who are speculating like a tax. The Deflationary structure of fees should help counterbalance the price drops from inflation if any. In the long-term as more CDPs are used, Kava should be a deflationary asset by design if all things go well

Q3:

In your allocation it is indicated that 28.48% of the tokens are in the "Token treasury" - where will these tokens be directed?

  • Answer: Investors in financing rounds prior to the IEO have entered into long-term lock-up agreements in-line with their belief in Kava’s exciting long-term growth potential and to allow the projects token price to find stability. Following the IEO, the only tokens in circulation will be those sold through the IEO on Binance and the initial Treasury tokens released.
  • No private sale investor tokens are in circulation until the initial release at the end of Q1 2020 and then gradually over the [36] months The initial Treasury tokens in circulation will be used for a mixture of ecosystem grants, the expenses associated with the IEO as well as initial market making requirements as is typical with a listing of this size. Kava remains well financed to execute our roadmap following the IEO and do not envisage any need for any material financings or token sales for the foreseeable future.

Q4:

Such a platform (with loans and stable coins) is just the beginning since these aspects are a small part of many Defi components. Will your team have a plan to implement other functions, such as derivatives, the dex platform once the platform is successfully launched?

  • Answer: We believe Kava is the foundation for many future defi products. We need stable coins, oracles, and other infrastructure first that Kava provides. Once we have that, we can apply these to derivatives and other synthetics more easily. For example, we can use the price feeds and USDX to enable users to place 100x leverage bets with each other. If they both lock funds into payment channels, then they can use a smart contract based on the price feed to do the 100x trade/bet automatically without counter party risk. In this way, Kava can expand its financial product offerings far beyond loans and stable coins in the future.

Q5:

There are several options for using USDX on the KAVA platform, one of which is Margin Trading / Leverage. Is this a selection function or a compulsory function? Wondering since there are some investors who don`t like margin. What is the level of leverage and how does a CDP auction work?

  • Answer: This is a good #Q . Kava simply provides loans to users in USDX stable coins. What the users do is completely up to them. They can use the loans for everyday payments if they like. Leverage and hedging are just the main use cases we foresee - there are many ways people can use the CDP platform and USDX.

Q6:

Most credit platforms do not work well in the current market. What will you do to attract more people to use your platform and the services you provide? Thank you

  • Answer: Most credit platforms do not work well in the current market? I think that isn't correct at least for DeFi. Even in the bear market, MakerDao and Compound saw good user growth. Regardless, our efforts at Kava to build the market are fairly product and BD focused. 1) we build more integrations of assets and expand financial services to attract new communities and users. 2) we focus on building partnerships with high quality teams to promote and build Kava's core user base. Kava is just the developer. Our great partners like Ripple, Stakewith.Us, P2P, Binance - they have the real users that demand Kava. They are like our system integrators that package Kava up nicely and present it to their users. In order to grow, we need to deepen our partnerships and bring in new ones around the world.

Q7:

KAVA functions as a reserve currency in situations where the system is undercollateralized. In such cases new KAVA is minted and used to buy USDX off the market until USDX becomes safely overcollateralized.

Meaning, there will be no max supply of KAVA?

  • Answer: Yes, there is no max supply of Kava.

Q8:

Why Kava?

  • Answer: ...because people are long BTC and the best way to go long BTC without giving up custody is Kava's platform. Because it is MakerDao for bitcoin. Bitcoin has a 10x market cap of ETH and Maker is 10x the size of Kava. I think we're pretty undervalued right now.

Q9:

How do you plan to make liquidity in Kava?

  • Answer: Working with Binance for the IEO and as the first exchange for KAVA to trade on will be a huge boost in increasing the liquidity of trading KAVA.

Q10:

Most crypto investors or crypto users prefer easy transaction and low fees, what can we expect from KAVA about this?

  • Answer: Transaction fees are very low and confirm if seconds. The user experience is quite good on Tendermint-based blockchains.

Q11:

How do I become a note validator on KavA?

Q12:

It is great to know that KAVA is the first DEFI-supported project sponsored by Binance Launchpad, do you think this is the meaning that CZ brings: Opening the DEFI era, as a leader, you feel like how ?

  • Answer: We are the first DeFi platform that Launchpad has supported. We are a very strategic blockchain for major crypto like BNB. Kava's platform will bring more utility to the users of BNB and the Binance DEX. It feels good of course to have validation from the biggest players in the space like Cosmos, Ripple, CZ/Binance, etc.

Q13:

Since decentralized finance applications is already dominating, how do you intend to surpass those leading in the market?

  • Answer: The leaders are only addressing ethereum. BTC, XRP, BNB, ATOM is a much larger set to go after that current players cannot.

Q14:

What does Ripple play in the Kava's ecosystem, since Ripple is like a top tier company and it’s impressive that you are partnered with them?

  • Answer: Ripple is an equity investor in Kava and a big supporter of our work in cross-chain settlement research and implementations. Ripple's XRP is a great asset in terms of users and liquidity that the Kava platform can use. In addition, Ripple's money service business customers are asking for a stable coin for remittances to avoid the currency heading risk that XRP presents. Ripple will not use USDC or other stable coins, but they are open to using USDX as it can be XRP-backed.

Q15:

Considering the connectivity, Libra could be the biggest competitor if KAVA leverages interchain for efficiency.

  • Answer: With regard to USDX, it is important to understand the users interacting with the Kava blockchain have no counterparty that people could go after for legal actions. A user getting a USDX loan has no counterparty. The software holds the collateral and creates the loan. The only laws that would apply are to the very users that are using the system.

Q16:

Wonder how KAVA will compete with the tech giants

  • Answer: Libra is running into extreme issues with the US Senate and regulators. Even the G7-G20 groups are worried. Its important to understand that Libra is effectively a permissioned system. Only big companies that law makers can go after are able to run nodes. In Kava, nodes can be run by anyway and our nodes are based all over the world. It's incredibly hard for a law maker to take down Kava because they would need to find and legally enforce hundreds of business in different jurisdictions to comply. We have an advantage in this way over the larger projects like Libra or Clayton.

Q17:

In long-term, what's the strategy that KAVA has for covering the traditional finance users as well? Especially regarding the "stability"

  • Answer: Technical risk is unavoidable for DeFi. Only time will tell if a system is trustworthy and its never 100% that it will not fail or be hacked. This is true with banks and other financial systems as well. I think for DeFi, the technical risk needs to be priced in to the expected returns to compensate the market. DeFi does have a better user experience - requiring no credit score, identity, or KYC over centralized solutions.
  • With our multi-collateral CDP system, even with it overcollateralized, people can get up to 3x leverage on assets. Take 100 USD in BTC, get a USDX loan for 66 USDX, then buy $66 BTC and do another loan - you can do this with a program to get 3x leverage with the same risk profile. This is enough for most people.
  • However, it will be possible once we have Kava's CDP platform to extend it into products that offer undercollateralized financial products. For example, if USER 1 + USER 2 use payment channels to lock up their USDX, they can use Kava's price feeds to place bets between each other using their locked assets. They can bet that for every $1 BTC/USD moves, the other party owes 3x. In this way we can even do 100x leverage or 1000x leverage and create very fun products for people to trade with. Importantly, even in places where margin trading is regulated and forbidden, Kava's platform will remain open access and available.

Q18:

In long-term, what's the strategy that KAVA has for covering the traditional finance users as well? Especially regarding the "stability"

  • Answer: Kava believes that stable coins should be backed not just by crypto or fiat, but any widely used, highly liquid asset. We think in the future the best stablecoin would be backed by a basket of very stable currencies that include crypto and fiat or whatever the market demands.

Q19:

Compound, maker they're trying to increase their size via the competitive interests rates. THough it shows good return in terms of growth rate, still it's for short-term. Wonder other than financial advantage, KAVA has more for the users' needs?

  • Answer: Robert, the CEO of Compound is an investor and advisor to Kava. We think what Compound does with money markets is amazing and hope to integrate when they support more than just Ethereum assets. Kava's advantage vs others is to provide basic DeFi services like returns on crypto and stable coins today when no other platform offers that. Many platforms support ETH, but no platform can support BTC, XRP, BNB, and ATOM in a decentralized way without requiring centralized custody of these assets.

Q20:

The vast majority of the cryptocurrency community's priorities is symbolic pricing. When prices rise, the community rejoices and grows. When they fall, many people begin to cast in a negative way. How will KAVA solve the negative problem when the price goes down? What is your plan to strengthen and develop the community to persuade more people to look at the product than the price?

  • Answer: We believe price is an important factor for faith in the market. One of Kava's key initiatives was selecting only long-term partners that are willing to work with kava for 2 years. That is why even after 6 months, 0 private investor or kava team tokens will be liquid on the market.
  • We believe not in fast pumps and then dumps that destroy faith, but rather we try and operate the best we can for long-term sustainable growth over time. It's always hard to control factors in the market, and some factors are out of our control such as BTC price correlations, etc - however, we treat this like a public company stock - we want long-term growth of Kava and try to make sure our whole community of Kava holders is aligned with that the best we can.

Q21:

Do you have any plans to attract non-crypto investors to Kava and how? What are the measures to increase awareness of kava in non-crypto space?

  • Answer: We are 100% focused on crypto, not the general market. We solve the problems of crypto traders and investors - not the average grandma who needs a payment solution. Kava is geared for decentralized leverage and hedging.

Q22:

Adoption is crucial for all projects and crypto companies, what strategy are you gonna use/follow or u are now following to get Kava adopted and used by many people all over the world?

Revenue is an important aspect for all projects in order to survive and keep the project/company up and running for long term, what are the ways that Kava generates profits/revenue and what is its revenue model?

  • Answer: We have already partnered with several large exchanges, long-term VCs, and large projects like Ripple and Cosmos. These are key ways for us to grow our community. As we build support for more assets, we plan to promote Kava's services to those new communities of traders.
  • Kava generates revenue as more people use the platform. As the platform is used, KAVA tokens are burned when users pay stability fees. This deflates the total supply of Kava and should in most cases give rise to the value of KAVA like a stock-buyback in the public markets.

Q23:

In order to be success in Loan project of Cryptocurrency, I think marketing is very important to make people using this service without any registration. What is main strategy for marketing?

  • Answer: Our main strategy is to build a great experience and offer products that are not available to communities with demand. Currently no DeFi products can serve BTC users for example. Centralized exchanges can, but nothing truly trustless. Kava's platform can finally give the vast audiences of BTC, BNB, and ATOM holders access to core DeFi services they cannot get on their own due to the smart contract limitations of those platforms.

Q24:

Currently, some project have policies for their ambassadors to create a contribution and attract recognition for the project! So the KAVA team plans to implement policies and incentives for KAVA ambassadors?

  • Answer: Yes, we will be creating a KAVA ambassador program and releasing that soon. Please follow our social media channels to learn about it in the coming weeks.

Q25:

Currently there are so many KAVA tokens sold on exchanges, why is this happening while KAVA is going to IEO on Binance? Are those KAVA codes fake or not?

  • Answer: For everyone's safety, please understand Kava tokens do not exist yet and they will only exist starting with the Binance IEO. Any other token listings or offerings of Kava are not supported by Kava Labs and I highly discourage you all from trying to get them there. It is most likely a big scam. Please only trust Binance for this.

Q26:

KAVA have two tokens, the first is called Kava - a governance and staking token; the second is called USDX - an algorithmically managed crypto-backed stable coin. What are the advantages of USDX compared to other stablecoins such as: USDT, USDC, TUSD, GUSD, ...?

  • Answer: USDX is one of the few stablecoins to be fully backed by crypto-assets. This means that we do not deal with fiat to back the value, and thus we don't have some of the issues when it comes to storing fiat funds with banks and custodians. This also makes our product fully digital and built for the future of crypto growth.

Q27:

As a CEO, does your background in Esports and Gaming industry help anything to your management and development of KAVA Labs?

  • Answer: Esports no. But having been a multi-time venture-backed foundeCEO and have gone through the start-up phase before has made creating and running a 2nd company easier. Right now Kava is still small, Fnatic had over 80 employees. It was at a larger scale. I would say developing software is much more than doing the hardware at fnaticgear.com

Q28:

Why did Kava choose to launch IEO on Binance and not other exchanges like: Kucoin, Houbi, Gate, ....?

  • Answer: Kava had a lot of interest from exchanges to partner with for IEO. We decided based on a lot of factors such as userbase, diverse exposure across multiple regions and countries, and an amazing team that provides so much insight into so many communities such as this one. Binance has been a tremendous partner and we also look forward to continuing our partnership far into the future.

Q29:

Currently if Search on coinmarketcap has 3 types of stablecoins bearing the USDX symbol (but these 3 stablecoins are no information). So, what will KAVA do to let users know that Kava's USDX is another stablecoin?

  • Answer: All these USDX have no volume or listings. We will be on Binance. I am not worried.

Q30:

In addition to the Token Allocation for Binance Launchpad, what is the Token Treasury in the Initial Circulating Supply?

  • Answer: This is controlled by Kava Labs, but with the big cash we have saved from fundraising, we see no reason why these tokens would be sold on the market. The treasury tokens are for use in grants, ecosystem growth initiatives, development, and other incentive programs to drive adoption of the platform.

Q31:

How you will compete with your competitors? Currently i don't see much but for future how you will maintain this consistency ? No doubt it is Great and Unique project, what is the main problem that #KAVA is currently facing?

  • Answer: Because our industry is just starting out, I don't like to think of them as our direct competitors. We are all working to grow the size of the pie rather than get a larger slice from a small pie. The one thing that we believe will allow us to stand apart is the community we are building. Being able to utilize our own community along with Cosmos and our other partners like Binance for the IEO, we have a strong footing to get a lot of early users onto our platform. Also, we are also focusing on growing Kava internationally particularly Asia. We hope to build our platform for an even larger userbase than just the west.

Q32:

How do you explain your project to a random person who has never heard of your project?

  • Answer: non-crypto = Kava is a lending platform for users of cryptocurrencies.
  • crypto = Kava is a cross-chain DeFi platform for loans and stablecoins backed by BTC, BNB, XRP, ATOM and other major cryptocurrencies.

Q33:

Will KAVA team have a plan on implementing DAO module on your platform since its efficiency on autonomy, decentralization and transparency?

  • Answer: All voting is already transparent on the Kava blockchain. We approved a number of proposals on our test net.

Q34:

how to use usdx token :only for your platform or you have plan to use usdx for payment ?

  • Answer: Payments is a nice use case, but demand for crypto payments is still small. We may choose to focus here later if demand for crypto payments increases. Currently it is quite small with the bulk of use remaining in trading and speculative use cases.

Q35:

Do you have plans to spread KAVA ecosystem across other continents. if yes, what are the strategies and how can I as a community member contribute to making it possible?

  • Answer: We are already across many continents - I don't think we are in antarctica yet. Africa might be light on nodes as well. I think as we grow on major exchanges like Binance, new node operators will get interested and help decentralize Kava further.

Q36:

Maker's CDP lending system is on top in this market and its Dominance is currently sitting on 64.90 % , how kava will compete will maker and compound?

  • Answer: adding assets like bitcoin which have more value and more users than ETH. It's a bigger market that Maker cannot compete with Kava in.

Q37:

Currently, the community is too concerned about the price. As prices rise, the community rejoice and grow, when falling, many people start throwing negatively. So what is KAVA's solution to getting people to focus on the project rather than the price of the token?

What is your plan to strengthen and grow the community to persuade more individuals to look at the product than the price?

  • Answer: We also share similar concerns as price and price direction is always a huge factor in the crypto industry. A lot of people of course are very short-term focused on flipping for bigger profits. One of the solutions, and what Kava has done, is to make sure that everything structured is for the long-term. So that makes sure that our investors and employees are all focused on long-term gains and growth. Locking vesting periods are part of that alignment. Another thing is that we at Kava are very transparent in our progress and development. We will be regularly posting updates within our own communities to allow our users and followers to keep up with everything we're up to. Please follow us or look at our github if you're interested!

Q38:

How did Kava get on Piexgo?

  • Answer: We did not work with Piexgo. We have not distributed tokens to any exchange other than Binance. I cannot speak to what is going on there, but I would be very wary of what is happening there.

Q39:

Why was the 1st round price so much lower than the current price

  • Answer: It is natural to worry that early investors got better pricing and could dump on the market. I can assure you that our investors are in this for the long-term. All private sale rounds signed 2 year contracts to run validators - and if they don't they forfeit their tokens. You can compare our release schedule to any other project. We have one of the most restricted circulating supply schedules of any project EVER and its because all our investors are commiting to the long-term success of the project and believe in Kava.
  • About the pricing itself - it is always a function of traction like for any start-up. When we made our public announcement about the project in June, we were only a 4 man team with just some github code. We could basically run a network with a single node, our own. Which is relatively worthless. I think our pricing of Kava at this time was justified. We were effectively a seed-stage company without a product or working network.
  • By July we made severe progress on the development side and the business side. We successful launched our first test net with the help of over 70 validator business partners around the world. We had a world-wide network of hundreds of people supporting us with people and resources at this point and the risk we would fail in launching a working product was much lower. At this point, the Kava project was valued at $25M. At this point, we had many VCs and investors asking for Kava tokens that we turned away. We only accepted validators that would help us launch the network. It was our one and only goal.
  • Fast forward to today, the IEO price simply reflects the traction and market demand for Kava. Our ecosystem is much larger than it was even a month ago. We have support from Ripple, Cosmos, and Binance amongst other large crypto projects. We have 100+ validators securing our network with very sophisticated high-availability set-ups. In addition, our ecosystem partners have built products for Kava - such as block explorers and others are working on native integrations to wallets and exchanges. Launchpad will be very big for us. Kava is a system designed to cater to crypto traders and investors and in a matter of days we distributed via Binance Launchpad and put in the hands of 130+ countries and tens of thousands of users overnight. It doesn't get more DeFi than that.

Q40:

What is the treasury used for?

  • Answer: Kava's treasury is for ecosystem growth activities.
  • Investors in financing rounds prior to the IEO have entered into long-term lock-up agreements in-line with their belief in Kava’s exciting long-term growth potential and to allow the projects token price to find stability. Following the IEO, the only tokens in circulation will be those sold through the IEO on Binance and the initial Treasury tokens released. No private sale investor tokens are in circulation until the initial release at the end of Q1 2020 and then gradually over the [36] months The initial Treasury tokens in circulation will be used for a mixture of ecosystem grants, the expenses associated with the IEO as well as initial market making requirements as is typical with a listing of this size. Kava remains well financed to execute our roadmap following the IEO and do not envisage any need for any material financings or token sales for the foreseeable future.

Q41:

Everyone have heard about the KAVA token, and read about it. But it would be great to hear your explanation about it. What is the Kava token, what is it's utility? :)

  • Answer: The Kava token plays many roles. KAVA is the native staking token of the Kava blockchain and is used for securing the network. KAVA is delegated to validators, basically professional node operators that run highly-available servers to secure the Kava blockchain. The top 100 validators by weight of staked KAVA earn block rewards that range from 3-20% APR based on the total amount staked in the network. These rewards are split between the validators and the KAVA holders.
  • When users of the platform repay their loans, they must a stability fee (a percentage of the loan) in KAVA tokens. These tokens are burned by the system, effectively deflating the total supply overtime as more users use the CDP system.
  • KAVA is also the primary token used in governance of the platform. KAVA token holders can vote on key system parameter changes and upgrades such as what assets to support, how much USDX in total can be loaned by the system, what the debt-to-collateral ratio needs to be, the stability fees, etc. KAVA holders have a very important responsibility to govern the system well.
  • Lastly, Kava functions as a "Lender of Last Resort" meaning if USDX ever gets undercollateralized because the underlying asset prices drop suddenly and the system manages it poorly, KAVA is inflated in these emergency situations and used to purchase USDX off the market until USDX reaches a state of being over collateralized again. KAVA holders have incentive to only support the good high quality assets so risk of the system is managed responsibly.

Q42:

No matter how perfect and technically thought-out a DeFi protocol is, it cannot be completely protected from any unplanned situations (such as extreme market fluctuations, some legal issues, etc.)

Ecosystem members, in particular the validators on whom KAVA relies on fundamental decision-making rights, should be prepared in advance for any "critical" scenario. Considering that, unlike the same single-collateral MakerDAO, KAVA will be a multi-collateral CDP system, this point is probably even more relevant here.

In this regard, please answer the following question: Does KAVA have a clear risk management model or strategy and how decentralized is / will it be?

  • Answer: Simialar to other CDP systems and MakerDAO we do have a system freeze function where in cases of extreme issues, we can stop the auction mechanisms and return all collateral.

Q43:

Did you know that "Kava" is translated into Ukrainian like "Coffee"? I personally do love drinking coffee. I plunge into the fantasy world. Why did you name your project "Kava" What is the story behind it? What idea / fantasy did your project originate from, which inspired you to create it?

  • Answer: Kava is coffee to you.
  • Kava is Hippopotamus to Japanese.
  • Cava is a region in Spain
  • Kava is also a root that is used in tea which makes your mouth numb.
  • Kava is also crow in Hindi.
  • Kava last but not least is a DeFi platform launching on Binance :)
  • We liked the sound of Kava it was as simple as that. It doesn't have much meaning in the USA where I am from. But it's short sweet and when we were just starting, Kava.io was available for a reasonable price

Q44:

What incentives does a lender get if a person chooses to pay with KAVA? Is there a discount on interest rates on the loan amount if you pay with KAVA? Do I have to pass the KYC procedure to apply for a small loan?

  • Answer: There is no KYC for Kava. Its an open blockchain software platform where anyone with a computer can connect to it and use it.

Q45:

Let's say, I decided to bond my cryptocurrency and got USDX stable coins. For now, it`s an unknown stable coin (let's be honest). Do you plan to add USDX to other famous exchanges? Also, you have spoken about the USDX staking and that the percentage would be higher than for other stable coins. Please be so kind to tell us what is the average annual interest rate and what are the conditions of staking?

  • Answer: Yes we have several large exchanges willing to support USDX from the start. Binance/Binance-DEX is one you should all know ;)
  • The average annual rates for USDX will depend on market conditions. The rate is actually provided by the CDP fees users pay. The system reallocates a portion of those fees to USDX users. In times when USDX use needs to grow, the rates will be higher to incentivize use. When demand is strong, we can reduce the rates.

Q46:

Why should i use and choose Kava's loan if i can use the similar margin trade on Binance?

  • Answer: If margin is available to you and you trust the exchange then you should do whatever is cheaper. For a US citizen and others, margin is often not available and if it is, only for a few asset types as collateral. Kava aims to address this and offer this to everyone.

Q47:

The IEO price is $ 0.46 while the price of the first private sale is $ 0.075. Don't you think that such price gap can negatively affect the liquidity of the token and take away the desire to buy a token on the exchange?

  • Answer: It is natural to worry that early investors got better pricing and could dump on the market. I can assure you that our investors are in this for the long-term. All private sale rounds signed 2 year contracts to run validators - and if they don't they forfeit their tokens. You can compare our release schedule to any other project. We have one of the most restricted circulating supply schedules of any project EVER and its because all our investors are commiting to the long-term success of the project and believe in Kava.
  • About the pricing itself - it is always a function of traction like for any start-up. When we made our public announcement about the project in June, we were only a 4 man team with just some github code. We could basically run a network with a single node, our own. Which is relatively worthless. I think our pricing of Kava at this time was justified. We were effectively a seed-stage company without a product or working network.

We had a world-wide network of hundreds of people supporting us with people and resources at this point and the risk we would fail in launching a working product was much lower. At this point, the Kava project was valued at $25M. At this point, we had many VCs and investors asking for Kava tokens that we turned away. We only accepted validators that would help us launch the network. It was our one and only goal.
  • Fast forward to today, the IEO price simply reflects the traction and market demand for Kava. Our ecosystem is much larger than it was even a month ago. We have support from Ripple, Cosmos, and Binance amongst other large crypto projects. We have 100+ validators securing our network with very sophisticated high-availability set-ups. In addition, our ecosystem partners have built products for Kava - such as block explorers and others are working on native integrations to wallets and exchanges. Launchpad will be very big for us. Kava is a system designed to cater to crypto traders and investors and in a matter of days we distributed via Binance Launchpad and put in the hands of 130+ countries and tens of thousands of users overnight. It doesn't get more DeFi than that.
  • TLDR - I think KAVA is undervalued and the liquid supply of tokens is primarily from the IEO so its a safer bet than other IEOs. If the price drops, it will be from the overall market conditions or fellow IEO users not due private sale investors or team sell-offs.

Q48:

Can you introduce some information abouts KAVA Deflationary Fee Structure? With the burning mechanism, does it mean KAVA will never reach its max supply?

  • Answer: When loans are repaid, users pay a fee in Kava. This is burned. However, Kava does not have a max supply. It has a starting supply of 100M. It inflates for block rewards 3-20% APR AND it inflates when the system is at risk of under collateralization. At this time, more Kava is minted and used to purchase USDX off the market until it reaches full collateralization again.
  • TLDR: If things go well, and governance is good, Kava deflates and hopefully appreciates in value. If things go wrong, Kava holders get inflated.

Q49:

In your opinion what are advantage of decentralized finance over centralized?

  • Answer: One of the main advantages is not needing to pay the costs of regulation and compliance. Open financial software that is usable by anyone removes middle men fees and reduces the barrier for new entrants to enter and make new products. Also DeFI has an edge in terms of onboarding - to get a bank account or an exchange account you need to do lots of KYC and give private info. That takes time and is troublesome. With DeFi you just load up your funds and transact. Very fast user flows.

Q50:

Plan, KAVA how to raise capital? Kava is being supported by more than 100 business entities around the world, including major cryptocurrency investment funds like Ripple and Cosmos, so what did kava do to convince investors to join the project?

  • Answer: We have been doing crypto research and development for years. Ripple and Cosmos were partners before we even started this blockchain with Kava Labs. When we announced Kava the DeFi platform they knew us already to do good work and they liked the idea so they support us.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.
Lessons learned?

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

Decred Journal — June 2018

Note: You can read this on GitHub, Medium or old Reddit to see the 207 links.

Development

The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response.
dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage.
Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun.
Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal.
Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue.
dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues.
Ticket splitting: 11-way ticket split from last month has voted (transaction).
Ethereum support in atomicswap is progressing and welcomes more eyeballs.
decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page.
decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here.
Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)

Network

Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s.
F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%.
Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak).
Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1.
Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).

ASICs

Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target.
Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.comtranslated, also on asicminervalue)
dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.

Integrations

bepool.org is a new mining pool spotted on dcred.eu.
Exchange integrations:
Two OTC trading desks are now shown on decred.org exchanges page.
BitPro payment gateway added Decred and posted on Reddit. Notably, it is fully functional without javascript or cookies and does not ask for name or email, among other features.
Guarda Wallet integrated Decred. Currently only in their web wallet, but more may come in future. Notable feature is "DCR purchase with a bank card". See more details in their post or ask their representative on Reddit. Important: do your best to understand the security model before using any wallet software.

Adoption

Merchants:
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project).
The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below.
Arbitrade is now mining Decred.

stakey.club: a new website by @mm:
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
@morphymore translated Placeholder's Decred Investment Thesis and Richard Red's write-up on Politeia to Chinese, while @DZ translated Decred Roadmap 2018 to Italian and Russian, and A New Kind of DEX to Italian and Russian.
Second iteration of Chinese ratings released. Compared to the first issue, Decred dropped from 26 to 29 while Bitcoin fell from 13 to 17. We (the authors) restrain ourselves commenting on this one.

Community Discussions

Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository.
An update on our communication systems:
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS.
A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people.
A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred.
"Against community governance" article was discussed on Reddit and #governance.
"The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here.
Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms.
Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.

Markets

DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market.
In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.

Relevant External

Obelisk announced Launchpad service. The idea is to work with coin developers to design a custom, ASIC-friendly PoW algorithm together with a first batch of ASICs and distribute them among the community.
Equihash-based ZenCash was hit by a double spend attack that led to a loss of $450,000 by the exchange which was targeted.
Almost one year after collecting funds, Tezos announced a surprise identification procedure to claim tokens (non-javascript version).
A hacker broke into Syscoin's GitHub account and implanted malware stealing passwords and private keys into Windows binaries. This is a painful reminder for everybody to verify binaries after download.
Circle announced new asset listing framework for Poloniex. Relevant to recent discussions of exchange listing bribery:
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss.
Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance".
Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case.
Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too?
