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.

Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

Can Blockchain Gaming Drive Cryptocurrency Adoption?

Can Blockchain Gaming Drive Cryptocurrency Adoption?
The gaming industry, with its approximately 2.5 billion gamers worldwide, is a lucrative target and an immense field of application for blockchain itself, Bitcoin and other cryptocurrencies that could no doubt give a mighty push toward taking and making the technology mainstream. Honestly, this is not quite a news as the efforts to establish cryptocurrencies in the entertainment sector have gone a long way, with varying degrees of success.
by StealthEX
What they were, how it fared, and where things are going now – these questions deserve their own inquiry. So let’s take a look at how gaming facilitates cryptocurrency adoption, in what ways, and whether exposing the blockchain tech to a user base of a third of the world’s population would help oil the wheels of this sportster in a major way and ultimately cause a tectonic shift in the gaming industry itself.

A Little Bit of History

As Bitcoin kicked off in late 2008, with its first transaction hitting, or effectively starting, the blockchain in early January of 2009, it had taken well over two years till the cryptocurrency got involved in online gambling. It was the now-defunct mobile poker platform, Switchpoker, a developer of an online poker room that started to accept Bitcoin as a deposit and payment option. You can still find a topic on Bitcointalk.org about this news dated back to November 23, 2011.
In April 2012, Erik Voorhees, an American entrepreneur and early Bitcoin adopter, founded Satoshi Dice, arguably the oldest online cryptocasino on the block, which is still pretty much alive today, although Voorhees sold it in a year. What makes it truly intriguing is the fact that during its early years the casino was generating half of all the transactions on the Bitcoin network. In short, online gambling was critically important in Bitcoin’s infancy years as it helped promote cryptocurrency awareness that led to future growth and expansion into other areas.
Some folks are certainly going to argue that gambling is not the same thing as gaming. The commonly accepted view is that gaming is based on skill while gambling on chance. We won’t debate over this point. However, as every poker player knows, the outcome of a poker game depends not only on luck, but also on skill and expertise. Put simply, there are large gray areas and overlaps. All things considered, our exposition would be missing a big chunk of significant history without giving due credit to gambling and how it helped Bitcoin adoption.
Now that online gambling is off our chest, we can safely turn to gaming as it is understood in the industry, and look at how it helped the blockchain space. One of the first uses of Bitcoin in a major game that we are aware of started in 2014 with the launch of BitQuest, a Minecraft server that used Bitcoin for in-game transactions. Within the gaming environment you could buy valuable in-game stuff from other users with the so-called bits, small fractions of a Bitcoin, and earn them by completing in-game tasks or challenges like killing local monsters.
BitQuest closed the server in summer of 2019, and its brand name now belongs to a different entity not involved with gaming, but it still produced an impact. In essence, this effort successfully demonstrated how a cryptocurrency, in this case Bitcoin, can be used in lieu of a native in-game currency that players can earn, buy and spend as well as withdraw. This has serious implications for two main reasons. First, Bitcoin, unlike any other purely in-game currency, has uses outside the game and its ecosystem, and, second, its supply cannot be manipulated by the game developers, which makes the game by far more fair and square.
Needless to say, the example that BitQuest had set encouraged other market participants to look into Bitcoin as an alternative option for in-game currencies. Another popular Minecraft server, PlayMC, also introduced Bitcoin into its world in 2015, but ceased the operation just two years later. There were a few other servers experimenting with altcoins, more specifically, Dogecoin, but most of them disappeared from the scene shortly thereafter, failing to attract enough die-hard Minecraft fans.

What Has Changed?

With the arrival of smart contract-enabled blockchains such as Ethereum, EOS and TRON, the phrase “blockchain gaming” has taken on a more literal meaning as these blockchains allow games to be designed and played entirely on-chain in much the same manner trades are made on a decentralized exchange. While TRON stands for “The Real-time Operating system Nucleus”, there is an obvious reference to a once popular arcade game based on a titular 1982 science fiction film that ultimately garnered a cult following.
CryptoKitties is likely the most popular game ever released in the Ethereum ecosystem and probably in the whole crypto space so far. Its test version was made available on October 19, 2017, and it was an instant success. By the end of 2017 over 200,000 people signed up for the game, spending over $20 million in Ether. We won’t delve into its “gameplay” as it is beyond the scope of this article, and most certainly you are well familiar with it anyway. But what we absolutely should write about is the effect it made and the repercussions it produced.
It could be said that CryptoKitties was to the Ethereum blockchain what Satoshi Dice had been to Bitcoin in the early days of crypto. At the peak of its popularity the game reportedly accounted for 20-25% of all Ethereum’s traffic that clogged the entire Ethereum network, with transaction fees skyrocketing. No wonder lots of people got pissed off with this turn of events. However, despite all the rage and fury, CryptoKitties amply demonstrated what a success means in the blockchain gaming field, how it looks and feels in practice.
It is hard to estimate how much CryptoKitties contributed to cryptocurrency adoption. But given that a few hundred thousand people got involved in this game alone and many more with dozens of blockchain games that it has spawned, like Etherbots, Gods Unchained, The Six Dragons, etc, this indisputable triumph surely counts as a massive contribution by any definition or metric. Moreover, it also revealed the weaknesses of the contemporary blockchain solutions and what exactly should be done to overcome them.
Evolution never goes linearly. In fact, it generally doesn’t go in curves, circles, or zig zags, either. It always moves along very diverse routes, directions and entire dimensions like plants and animals, viruses and bacteria, and, well, dinosaurs and mammals. The evolution of gaming in crypto space is no different. СryptoKitties and other games share essentially the same tech under the hood – building games on some advanced general-purpose blockchain such as Ethereum. But it is not the only front that crypto gaming has been advancing on, nor is it the only way to introduce gaming to cryptocurrencies, and vice versa.
A more recent approach is based on designing either a standalone cryptocurrency or a token on a smart contract-enabled blockchain to be used across many games that support it as an in-game currency. As a result, gamers can enjoy true ownership of their in-game assets (the so-called non-fungible tokens, or NFTs), safe item trading outside the game, and cross-game compatibility. This path has been taken by such projects as Enjin (ENJ), GAME Credits (GAME), Decentraland (MANA), WAX (WAXP) and others, with their respective cryptocurrencies fueling a range of games.
A somewhat different avenue is taken by Funfair (FUN), Chromia (CHR) and Lucid Sight, which are offering platforms that blockchain games can be built on. Thus, Lucid Sight’s Scarcity Engine is focused more on game creators than end users, that is to say, gamers, allowing developers to integrate blockchain into their games. It aims to obliterate the difference between blockchain-based games and traditional gaming platforms. Funfair, on the other hand, leans more toward creating custom-built blockchain casinos, with its FUN token as a casino “chip”. So much for no more gambling, huh.
Our account of events would be incomplete if we didn’t mention yet another attempt to make use of Minecraft for the purpose of introducing cryptocurrencies to the gaming public. This time, a new Minecraft mod called SatoshiQuest has emerged. To participate in it, the gamers pay $1 in Bitcoin and get one in-game life. The pooled coins make up the loot, and the challenge is to find a minimum of 400 key fragments into which the keys to the Bitcoin wallet containing the prize are divided. And who said that evolution doesn’t loop?

Challenges and Future Prospects

The knockout popularity of СryptoKitties has clearly shown the scale of cryptocurrency mass adoption that blockchain gaming can trigger. As the game developers themselves put it, their “goal is to drive mainstream adoption of blockchain technology”. They believe that “the technology has immense benefits for consumers, but for those benefits to be realized, it needs to be experienced to be understood”. Speaking more broadly, as more people start using cryptocurrencies for gaming, they may eventually become interested in using their coins for purposes other than playing one game or another.
With that said, it is now as clear that there are two main barriers on the way there. The first is the limitations of the blockchain tech itself that essentially limits blockchain gaming to NFTs, in-game currencies, streamlined payments, and similar stuff. This is mostly a technical challenge anyway, and we could realistically expect it to be solved sooner or later. The other issue is applicable to the gaming industry as a whole. People en masse would only play games that are truly engaging and immersive, technical issues aside.
So the bottom line is that we need the convergence of these two vectors to make blockchain a dominating force in the gaming industry. First, the blockchain tech should have the capacity for running multiplayer games that major video game developers like Blizzard, Valve and Ubisoft produce, no trade-offs here. Then, we actually need the games like Warcraft, Counter-Strike or Far Cry that can be played on blockchain, to make it matter. Only after we get there, the gaming industry will likely become a primary driver behind cryptocurrency adoption.

The next XVG? Microcap 100x potential actually supported by fundamentals!

What’s up team? I have a hot one for you. XVG returned 12 million percent in 2017 and this one reminds me a lot of it. Here’s why:
Mimblewimble is like Blu-Ray compared to CD-ROM in terms of its ability to compress data on a blockchain. The current BTC chain is 277gb and its capacity is limited because every time you spend a coin, each node needs to validate its history back to when it was mined (this is how double spending is prevented). Mimblewimble is different - all transactions in a block are aggregated and netted out in one giant CoinJoin, and only the current spending needs to be verified. This means that dramatically more transactions can fit into a smaller space, increasing throughput and lowering fees while still retaining the full proof of work game theory of Bitcoin. These blockchains are small enough to run a full node on a cheap smartphone, which enhances the decentralization and censorship resistance of the network.
The biggest benefit, though, is that all transactions are private - the blockchain doesn’t reveal amounts or addresses except to the actual wallet owner. Unlike earlier decoy-based approaches that bloat the chain and can still be data mined (XMR), Mimblewimble leaves no trace in the blockchain, instead storing only the present state of coin ownership.
The first two Mimblewimble coins, Grin and Beam, launched to great fanfare in 2019, quickly reaching over $100m in market cap (since settled down to $22m and $26m respectively). They are good projects but grin has infinite supply and huge never-decreasing emission, and Beam is a corporate moneygrab whose founding investors are counting on you buying for their ROI.
ZEC is valued at $568m today, despite the facts that only 1% of transactions are actually shielded, it has a trusted setup, and generating a confidential transaction takes ~60 seconds on a powerful PC. XMR is a great project but it’s valued at $1.2b (so no 100x) and it uses CryptoNote, which is 2014 tech that relies on a decoy-based approach that could be vulnerable to more powerful computers in the future. Mimblewimble is just a better way to approach privacy because there is simply no data recorded in the blockchain for companies to surveil.
Privacy is not just for darknet markets, porn, money launderers and terrorists. In many countries it’s dangerous to be wealthy, and there are all kinds of problems with having your spending data be out there publicly and permanently for all to see. Namely, companies like Amazon are patenting approaches to identify people with their crypto addresses, “for law enforcement” but also so that, just like credit cards, your spending data can be used to target ads. (A) Coinbase is selling user data to the DEA, IRS, FBI, Secret Service, and who knows who else? (B) What about insurance companies raising your premiums or canceling your policy because they see you buying (legal) cannabis? If your business operates using transparent cryptocurrency, competitors can data mine your customer and supply chain data, and employees can see how much everyone else gets paid. I could go on, but the idea of “I have nothing to hide, so what do I care about privacy?” will increasingly ring hollow as people realize that this money printing will have to be paid by massive tax increases AND that those taxes will be directly debited from their “Central Bank Digital Currency” wallets.
100% privacy for all transactions also eliminates one HUGE problem that people aren’t aware of yet, but they will be: fungibility. Fungibility means that each coin is indistinguishable from any other, just like paper cash. Why is this important? Because of the ever-expanding reach of AML/KYC/KYT (Anti-Money Laundering / Know Your Customer / Know Your Transaction) as regulators cramp down on crypto and banks take over, increasingly coins become “tainted” in various ways. For example, if you withdraw coins to a mixing service like Wasabi or Samourai, you may find your account blocked. (C) The next obvious step is that if you receive coins that these chainalysis services don’t like for whatever reason, you will be completely innocent yet forced to prove that you didn’t know that the coins you bought were up to no good in a past life. 3 days ago, $100k of USDC was frozen. (D) Even smaller coins like LTC now have this problem, because “Chinese Drug Kingpins” used them. (E) I believe that censorable money that can be blocked/frozen isn’t really “your money”.
Epic Cash is a 100% volunteer community project (like XVG and XMR) that had a fair launch in September last year with no ICO and no premine. There are very few projects like this, and it’s a key ingredient in Verge’s success (still at $110m market cap today despite being down 97% since the bubble peak) and why it’s still around. It has a small but super passionate community of “Freemen” who are united by a belief in the sound money economics of Bitcoin Standard emission (21m supply limit and ever-decreasing inflation) and the importance of privacy.
I am super bullish on this coin for the following reasons:
Because it doesn’t have a huge marketing budget in a sea of VC-funded shitcoins, it is as-yet undiscovered, which is why it’s so cheap. There are only 4 Mimblewimble-based currencies on the market: MWC at $162m, BEAM at $26m, GRIN at $22m, and EPIC at $0.4m. This is not financial advice and as always, do your own research, but I’ve been buying this gem for months and will continue to.
This one ticks all the boxes for me, the only real problem is that it’s hard to buy much without causing a huge green candle. Alt season is coming, and coins like this are how your neighbor Chad got his Lambo back in 2017. For 2021, McLaren is a better choice and be sure to pay cash so that it doesn’t get repossessed like Chad!

Is Paxful against responsible disclosure of vulnerabilities or is this all just a mistake? $10-$200 free BTC if we can resolve this

TLDR; I discovered and responsibly disclosed multiple bugs/vulnerabilities with significant impact on Paxful's marketplace, weeks later Paxful froze my account thinking I was maliciously making use of part of the very vulnerability I reported. I was testing whether had been fully patched as it posed risks to my operations as a vendor as well as Paxful's marketplace as a whole if it were publicly disclosed and abused by malicious actors. I would be happy to consider signing the NDA related to this vulnerability if we can resolve this in a timely manner. Things ended in my vendor account being bannéd nearly 2 weeks ago as the support and security team assumed API testing activity was spam despite my prior in-depth communications with them. They cited multiple warnings August 6-18 which, as cited below are not legitimate in nature and likely due to a break down in communications and/or failure to investigate the nature of my activity. I suspect some of this may be related to a language barrier as I and other vendors frequently receive messages in broken english containing incorrect or irrelevant information.
Please consider posting a comment regarding your experience with Paxful's bug bounty program or support team.
I am offering $10 in BTC to each Paxful ID verified user who comments on this post with a relevant comment if my Paxful account's ban is lifted. Moderators are excluded from this to avoid conflicts of interest. Additional restrictions:
Alternatively, if this post does not receive atleast 20 comments from ID verified users, I am offering $200 in BTC to anyone who can put me in touch with someone at Paxful who can actually resolve this. Payout will be made only if my vendor account ban is lifted.
5/17/20 — I reported vulnerability #1 to [[email protected]](mailto:[email protected])
07/06/20 — I reported vulnerability #2 to [[email protected]](mailto:[email protected]) "Trade transcripts can be made unretrievable, when abused by users moderators might be unable to review disputes" to [[email protected]](mailto:[email protected]) . Some of the testing involved posting arbitrary strings such as “aa.co”, “bbco”, etc. repeatedly to old cancelled trades. This is not spam, however it’s been wrongly assumed to be spam.
08/05/20 — Despite my clearly positive intentions, I was advised by a Paxful dev ops engineer to not attempt to mitigate the risk of coin lockers, scammers and extortion through the use of automated scripted messaging in trade chats as it could cause problems for Paxful staff. I was asked to strictly rely on moderators for resolving such issues (despite the historical lack of recourse against scams). I immediately ceased such activity and made it clear I was prepared to comply with this request and was previously unaware that this might cause problems for staff.
08/06/20 — No further use of scripted messaging to get rid of coin lockers, I opted to strictly rely on moderators for such issues. I performed tests via Paxful’s API related to the bug bounty report on 07/06/20 using specific API endpoints on trades where it would not hinder any transaction or where staff might need to be involved.
Criteria used for selected trades to use for vulnerability testing:
Ideally I would have used a test account or testnet like most exchanges offer but I was specifically told not to and prior to 08/05/20 there were no concerns about my usage of Paxful's API.
08/08-10/20 — (Request # 221122 ) My vendor account was frózen, I tweeted at raypaxful and it was unfrózen. I was told by support (request # 221122) that my API testing was flagged by Paxful’s system as spam. Support issued an apology and placed a note on my account that I may be performing such tests going forward and they valued my bug bounty reports.
08/12/20 — I was wrongly accused again of spamming the trade chat despite my continued compliance with the request from [[email protected]](mailto:[email protected]) on 08/05/20. Two trades were cited:GYokxnZdbmx — blatantly obvious API testing involving posting repeated strings such as “aa.co”
6Jm586J6Mox — trade from 04/21/20, why are you warning me about a trade from 4 months ago when it wasn’t indicated that Paxful had an issue with scripted message being use to deal with malicious actors when moderators are nowhere in sight? After all these months, why didn’t you take any action against the malicious user here? This doesn’t require contacting any gift card company, you can clearly see this user provided a cropped picture of a gift card making it unredeemable yet they locked my coins for days. The reason you’re aware of activity like this being a risk to the marketplace is a direct result of the bug bounty report I filed on on 07/06/20 for which I was never paid despite being promised a "reward". Who in their right mind is going to file a bug bounty report and then proceed to abuse that bug? A little more investigation and logical reasoning is needed here.
08/18/20 (Request # 170377) I was accused yet again of spamming the trade chat despite my continued compliance with the request from [[email protected]](mailto:[email protected]) on 08/05/20. I responded to this reminding support that I had continued to comply with this request and that “warning” me of something I’ve been in compliance with ever since I was aware of the issue is extremely disingenuous.
08/19/20 (Request # 170377), BitcoinBell’s response:*“Spamming and account notation: Like I said, I've communicated with [Paxful dev ops engineer name redacted] multiple times regarding excessive scripted messaging being used to ward off scammers, the behavior won't continue.”*Scripted messaging posted via API to deal with scammers had not taken place ever since the concern was first brought to my attention on 08/05/20. Paxful support appears to have been under the impression that this was not the case and proceeded to “warn me” again as if I was refusing to comply with their prior request. It would appear that they did not realize my activity was bug bounty related testing using old cancelled trades as my only authorized means of carrying out such tests without being disruptive to transactions.
“Had I known this caused problems for Paxful's team I wouldn't have done it but there was no mention in Paxful's API documentation that such activity could cause problems for Paxful's team. Most websites have proper rate limiting in place to deal with excessive posting of the same message so they don't have to waste their time policing what messages are being posted. Again, I'm not arguing for continuing this behavior as it's now been made clear it causes problems for Paxful's team but I hope you can see nothing in Paxful's API documentation clearly prohibits such use and that it was being used in good faith to ward off bad actors. In a marketplace filled with malicious actors, I don't appreciate being "warned" as if I did something malicious here when there was no indication of it being a problem, until recently.” (and have been in compliance with the request since first alerted on 08/05/20)”
08/21/20 I was offered a bug bounty payout for the vulnerabilities/bugs reported on 07/06/20 and 05/17/20. The amount was around 5-12% of the national average for bug bounty payouts. I was asked to sign a lengthy NDA which I had to forward to my attorney for review.
08/26/20 I made a counteroffer to the proposed bug bounty payments around and below the national average for bug bounty payouts.
08/26/20 I reported a new bug to [[email protected]](mailto:[email protected]) that could lead to users visiting malicious sites from Paxful's trade chat without warning.
08/27/20 8:01 AM UTC I reported a new bug to [[email protected]xful.com](mailto:[email protected]) that significantly impacted vendors in countless payment methods which since been patched:"Regex intended to block external contact info also blocks all gift card numbers that contain 6 sequential digits, huge potential burden on vendors, confusion for buyers"
08/27/20 8:30 AM UTC I received an e-mail that my vendor account had been bannéd. Despite having several active trades, the 0.1 BTC bond and all funds were made available for my immediate withdrawal. What's the point of a 0.1 BTC bond if Paxful makes it immediately available to bannéd users with active trades?
Is Paxful against responsible disclosure or is this all just a coincidence? The vulnerability I reported on 07/06/20 specifically alerted Paxful’s security team to risks of spam and difficulties it might create for users and moderators if moderators did not have special tools that would make this a non-issue. No concerns related to this vulnerability were made apparent until 08/05/20.
For the sake of brevity I'm leaving out a number of other material ongoing and prior issues encountered with Paxful support that impeded my ability to provide seamless service on Paxful's platform. I have gone to great lengths to articulate these issues to support with little/no resolution despite their often simplistic nature.

Trading expenses are incurred when an order is prepared by means of the Bittrex worldwide matching engine. While an order is being executed, the purchaser and the vendor are charged a rate primarily based on the order’s amount. The fee charged by Bittrex exchange is calculated by the formula amount * buy rate * fee. There aren't any charges for placing an order which is not being executed so far. Any portion of an unfinished order will be refunded completely upon order cancelation.
Prices vary depending on the currency pair, monthly trade volume, and whether the order is a maker or taker. Bittrex reserves the right to alternate fee quotes at any time, including offering various discounts and incentive packages.

6. Withdrawing Funds

You determine the crypto address—to which the amount will be credited—and the transaction amount. The withdrawal fee will be automatically calculated and shown right away.
After confirming the transaction, the finances will be sent to the specified addresses and all that you need to do is to wait for the community to confirm the transaction.
If the 2FA is enabled, then the user receives a special code (via SMS or application) to confirm the withdrawal.

7. How to Trade on Bittrex Global

Currency selling and buying transactions are performed using the Sell and Buy buttons, accordingly.
To begin with, the dealer selects a currency pair and sees a graph of the rate dynamics and different values for the pair.
Below the chart, there is a section with orders where the user can buy or sell a virtual asset.
To create an order, you just need to specify the order type, price, and quantity. And do not forget about the 0.25% trade fee whatever the quantity.
For optimum profit, stay with liquid assets as they can be quickly sold at a near-market rate effective at the time of the transaction. Bittrex offers no referral program; so buying and selling crypto is the easiest way to earn.

Order Types

Bittrex helps you alternate Limit and Stop-Limit orders.
A limit order or a simple limit order is performed when the asset fee reaches—or even exceeds—the price the trader seeks. To execute such an order, it is required that there's a counter market order on the platform that has the identical fee as the limit order.

Differences between Limit Order and Stop Limit Order

A stop limit order is a mixture of a stop limit order and a limit order. In such an application, charges are indicated—a stop charge and the limit.

Stop Limit Order Purpose

https://preview.redd.it/hlxvy9ti4zh51.jpg?width=1141&format=pjpg&auto=webp&s=064a77459a4dcb4555a885cbc56629aae10fc38b

Trade Terminal

Let’s discuss how you could trade conveniently with our service.
The key features include a user-friendly interface and precise currency pair statistics (timeframe graphs, network data, trade volumes, and so forth).
The platform’s top-notch advantage is handy, easy-to-analyze, customizable charts. There is also a column for quick switching between currency pairs and an order panel beneath the fee chart. Such an all-encompassing visual solution helps compare orders efficiently and in one place.
You can use the terminal in a day or night mode; when in the night mode, the icon in the upper-right corner changes and notice the Bittrex trading terminal in night mode is displayed. The main menu consists of 4 sections: Markets, Orders, Wallets, Settings.
Markets are the trade section. Bittrex allows handling over 270 currency pairs.
Orders. To see all open orders, go to OrdersOpen.
To see completed orders, go to OrdersCompleted.
Wallets. The Wallets tab displays many wallets for all cryptocurrencies supported by the exchange and the current balance of each of them.
After refilling the balance or creating a buy or sale order, you will see all actions in the section. Bittrex allows creating a separate wallet for every coin. Additionally, you can see how the coin price has changed, in terms of percentage, throughout the day.
Here’s what you can also do with your wallets:
  • Hide zero balances: hide currencies with zero balance
  • Green and red arrows: replenish balance/withdraw funds
  • Find: search for a cryptocurrency
The Settings section helps manage your account, verification, 2FA, password modification, API connection, and many more.

How to Sell

The process of selling crypto assets follows the same algorithm. The only difference is that after choosing the exchange direction, you need to initiate a Sell order. All the rest is similar: you select the order type, specify the quantity and price, and click Sell *Currency Name* (Sell Bitcoin in our case).
If you scroll the screen, the entire history of trades and orders will be displayed below.

LONG and SHORT

You can make a long deal or a short deal. Your choice depends on whether you expect an asset to fall or rise in price.
Long positions are a classic trading method. It concerns purchasing an asset to profit when its value increases. Long positions are carried out through any brokers and do not require a margin account. In this case, the trader’s account must have enough funds to cover the transaction.
Losses in a long position are considered to be limited; no matter when the trade starts, the price will not fall below zero with all possible errors. Short positions, in contrast, are used to profit from a falling market. A trader buys a financial instrument from a broker and sells it. After the price reaches the target level, the trader buys back the assets or buys them to pay off the initial debt to the broker.
A short position yields profit if the price falls, and it is considered unprofitable the price matches the asset value. Performing a short order requires a margin account as a trader borrows valuable assets from a broker to complete a transaction. Long transactions help gain from market growth; short from a market decline.

Trade via API

Bittrex also supports algorithmic trading through extensive APIs (application programming interface), which allows you to automate the trading process using third-party services.
To create an API key, the user must enable the two-factor authentication 2FA, verify their account, and log in to the site within 3 minutes.
If all the requirements of the system are fulfilled, you can proceed to generate the API key. Log in to your Bittrex account, click Settings. Find API Keys. Click Add new key (Create a new key).
Toggle on / off settings for READ INFO, TRADE, or WITHDRAW, depending on what functionality you want to use for our API key.
Click Save and enter the 2FA code from the authenticator → Confirm.
The secret key will be displayed only once and will disappear after the page is refreshed. Make sure you saved it!
To delete an API key, click X in the right corner for the key that you want to delete, then click Save, enter the 2FA code from the authenticator and click Confirm.

Bittrex Bot, a Trader’s Assistant

Robotized programs that appeared sometimes after the appearance of cryptocurrency exchanges save users from monotonous work and allow automating the trading process.
Bots for trading digital money work like all the other bots: they perform mechanical trading according to the preset parameters.
Currently, one of Bittrex’s most popular trading bots is Bittrex Flash Crash Buyer Bot that helps traders profit from altcoin volatility without missing the right moment.
The program monitors all the market changes in the market every second; also, it even can place an order in advance. The Bittrex bot can handle a stop loss—to sell a certain amount of currency when the rate changes in a favorable direction and reaches a certain level.

8. Secure Platform

Bittrex Global employs the most reliable and effective security technologies available. There are many cases of theft, fraud. It is no coincidence that the currency is compared to the Wild West, especially if we compare the 1800s when cowboys rushed to the West Coast of America to earn and start something new in a place that had no rules.
Cryptocurrency is still wild. One can earn and lose money fast. But Bittrex has a substantial security policy thanks to the team’s huge experience in security and development for companies such as Microsoft, Amazon, Qualys, and Blackberry.
The system employs an elastic, multi-stage holding strategy to ensure that the majority of funds are kept in cold storage for extra safety.
Bittrex Global also enables the two-factor authentication for all users and provides a host of additional security features to provide multiple layers of protection.

How to Pass IP Verification

To ensure higher security of your Bittrex Global account, the system requires all users to approve each new IP address through an email confirmation. This IP verification procedure is required every time you attempt to log in from a new IP Address.
Confirming your IP address.

To ensure even more security, Bittrex Global supports whitelisting of IP addresses and Crypto addresses. These two features can help protect the account in the event of credentials or API key loss.

How to Add IP Address to Whitelist

By setting one or more whitelisted addresses, you are telling Bittrex Global to only authorize trades or withdrawals from those IPs. This concerns both the global.bittrex.com web interface and API-based trades or withdrawals. To do this, click IP Whitelist in Site Settings.
https://preview.redd.it/m2klahja5zh51.jpg?width=971&format=pjpg&auto=webp&s=7cfb941ecb5284973baed1a2b0301459e36a0ab6

How to Add Crypto Address to Whitelist

By setting a withdrawal address, you are telling Bittrex Global to authorize withdrawals only to that address.
This concerns both the global.bittrex.com web interface and API based withdrawals.
Note that when opting into this feature, you need to specify a withdrawal address would like to withdraw funds from for every currency. To do this, click Withdrawal Whitelist in the Site Settings section. The example below shows a BTC address.

Bittrex Review: One of the First Crypto Exchanges Part 1

Bittrex Review: One of the First Crypto Exchanges Part 1

By Rinat Arslanov, CEO at Revain
Despite the fact that digital asset trading is a relatively new phenomenon, among cryptocurrency exchanges Bittrex is considered a time-tested trading platform that can guarantee a high level of security and reliable service. Today, in this all-encompassing review, we will study how Bittrex Global, one of the most popular and secure crypto exchanges, operates.

  • Bittrex History and Founders
  • What Bittrex Is and How It Works

1. Bittrex History and Founders

Bittrex Global is currently the oldest holding company concerned professionally with digital assets, as well as having access to major US and European financial markets. It grew out of a small cryptocurrency exchange that started with mining bitcoins for $30 back in 2011. Now the holding, whose headquarters is located in the Principality of Liechtenstein, provides a trading infrastructure to its users, enjoying a reputation of one of the safest exchanges in the world.
Bittrex Global has managed to gain such customer trust and loyalty through the continuous development and implementation of the most advanced technologies that have proven their worth by continuous and reliable operation throughout the 7 years of their existence. The company always ensures fair opportunities for investing in and trading digital assets for all clients, regardless of trading experience.

To this day, since January 2018, Bitcoin has not been able to rise higher than that time.
https://preview.redd.it/nqcifr3hodc51.jpg?width=974&format=pjpg&auto=webp&s=dfb81067c58d42dcf423b303b2e108d04c5121c9
The future Bittrex team really wanted a way to acquire Bitcoins again. Mining was going to prove untenable, so they brainstormed and started the first crypto-based business—GiftcardBTC.
At that time, Bittrex had a simple idea of earning through selling gifts and calling cards for Bitcoin. It was so easy to earn cryptocurrency and then convert it into fiat US dollars, and that endeavor made it possible to offset the costs. Then, the founders of the future cryptocurrency platform designed a Bitcoin miner that started to earn money continuously, but this was not the limit of their dreams.
Less than a year later, the first cryptocurrencies—Bitcoin and its fork Litecoin—got up in price many times and then the creators of Bittrex added Litecoin to their package. Using Coinpayments.net infrastructure for processing payments, they ran into problems, since there were still practically no abilities to convert or withdraw cryptocurrencies into fiat currencies. The founders began to look for convenient automatic ways to do this but at that time exchanges could not provide such services.
At that time, Bill Shihara and Richie Lai regularly traveled to Las Vegas and in late 2013, during one of such trips, they were discussing the problems they faced for many hours, trying to find a solution and considering various options. In the end, they decided to start software development in the west. Now this decision is considered the birthday of the Bittrex trading crypto platform.
They decided to invite a professional from Microsoft, Rami Kawach, to discuss their idea. After some time, they had an ambitious plan to develop and launch a platform for crypto exchange in less than two months. The plan was accompanied by a gentleman's dispute among Rami, Richie, and Bill over a bottle of 25-year-old whiskey, which concerned the timing of the plan.
The formed team began to work actively on a project to which they devoted all their free time and worked day and night. In mid-February 2014, they launched the Bittrex website, and on the last day of February, they made it accessible for the general public. As a result, Richie and Rami won over whiskey against Bill.

It was then when a large partnership began; later, the alliance ensured the joint company’s future success. They formulated several postulates that became the cornerstone of their business:
  1. We ourselves will never trade cryptocurrencies on our exchange. Too many shadows occurred in too many places, and we will not trade against our clients.
  2. We will always maintain honesty on our exchange. No one gets special information. No one gets special prices. Transparency is paramount.
  3. We will never sacrifice long-term gain for short-term gain. We have been together for a long time.

2. What Bittrex Is and How It Works

Bittrex is a multi-currency trading platform where you can exchange, buy, or sell cryptocurrency and fiat money. The exchange is available in all facets: you have great opportunities in making foreign exchange transactions, both with digital assets and with ordinary money.
Not everyone understands what fiat currencies are, but in fact, these are the good old usual paper cash and non-cash money that are issued by the central banks of various states. Fiat money mainly differs from cryptocurrencies in that it is regulated by governments, which can influence their output and exchange rate.
On the Bittrex crypto exchange, you will find more than a quarter of thousand of various types of cryptocurrencies and 364 currency pairs. A currency pair is a pair of currencies that can be exchanged one for another at a certain rate. The most common currencies can be exchanged for hundreds and thousands of other currencies, both digital and fiat. Cryptocurrencies such as Bitcoin Litecoin or Ether have the largest number of pairs available for exchange.
Appearance cements the first impression, and the user interface is key in any digital. In Bittrex, the interface is intuitive even for those taking their first steps in trading. Not only does it look sleek but it’s also very easy-to-use. You only see what you need on the trading screen.
Here you can see structured information about trading pairs, history of changes in exchange rates, and wallets. The website will guide you on how to make a deposit, how to work with orders, what happens to your money, and how to withdraw it.
All work with such a platform begins with the opening of an exchange account. You can find everything you need to configure a wallet in Settings.

RESEARCH REPORT ABOUT KYBER NETWORK

RESEARCH REPORT ABOUT KYBER NETWORK
Author: Gamals Ahmed, CoinEx Business Ambassador

https://preview.redd.it/9k31yy1bdcg51.jpg?width=936&format=pjpg&auto=webp&s=99bcb7c3f50b272b7d97247b369848b5d8cc6053

ABSTRACT

In this research report, we present a study on Kyber Network. Kyber Network is a decentralized, on-chain liquidity protocol designed to make trading tokens simple, efficient, robust and secure.
Kyber design allows any party to contribute to an aggregated pool of liquidity within each blockchain while providing a single endpoint for takers to execute trades using the best rates available. We envision a connected liquidity network that facilitates seamless, decentralized cross-chain token swaps across Kyber based networks on different chains.
Kyber is a fully on-chain liquidity protocol that enables decentralized exchange of cryptocurrencies in any application. Liquidity providers (Reserves) are integrated into one single endpoint for takers and users. When a user requests a trade, the protocol will scan the entire network to find the reserve with the best price and take liquidity from that particular reserve.

1.INTRODUCTION

DeFi applications all need access to good liquidity sources, which is a critical component to provide good services. Currently, decentralized liquidity is comprised of various sources including DEXes (Uniswap, OasisDEX, Bancor), decentralized funds and other financial apps. The more scattered the sources, the harder it becomes for anyone to either find the best rate for their trade or to even find enough liquidity for their need.
Kyber is a blockchain-based liquidity protocol that aggregates liquidity from a wide range of reserves, powering instant and secure token exchange in any decentralized application.
The protocol allows for a wide range of implementation possibilities for liquidity providers, allowing a wide range of entities to contribute liquidity, including end users, decentralized exchanges and other decentralized protocols. On the taker side, end users, cryptocurrency wallets, and smart contracts are able to perform instant and trustless token trades at the best rates available amongst the sources.
The Kyber Network is project based on the Ethereum protocol that seeks to completely decentralize the exchange of crypto currencies and make exchange trustless by keeping everything on the blockchain.
Through the Kyber Network, users should be able to instantly convert or exchange any crypto currency.

1.1 OVERVIEW ABOUT KYBER NETWORK PROTOCOL

The Kyber Network is a decentralized way to exchange ETH and different ERC20 tokens instantly — no waiting and no registration needed.
Using this protocol, developers can build innovative payment flows and applications, including instant token swap services, ERC20 payments, and financial DApps — helping to build a world where any token is usable anywhere.
Kyber’s fully on-chain design allows for full transparency and verifiability in the matching engine, as well as seamless composability with DApps, not all of which are possible with off-chain or hybrid approaches. The integration of a large variety of liquidity providers also makes Kyber uniquely capable of supporting sophisticated schemes and catering to the needs of DeFi DApps and financial institutions. Hence, many developers leverage Kyber’s liquidity pool to build innovative financial applications, and not surprisingly, Kyber is the most used DeFi protocol in the world.
The Kyber Network is quite an established project that is trying to change the way we think of decentralised crypto currency exchange.
The Kyber Network has seen very rapid development. After being announced in May 2017 the testnet for the Kyber Network went live in August 2017. An ICO followed in September 2017, with the company raising 200,000 ETH valued at $60 million in just one day.
The live main net was released in February 2018 to whitelisted participants, and on March 19, 2018, the Kyber Network opened the main net as a public beta. Since then the network has seen increasing growth, with network volumes growing more than 500% in the first half of 2019.
Although there was a modest decrease in August 2019 that can be attributed to the price of ETH dropping by 50%, impacting the overall total volumes being traded and processed globally.
They are developing a decentralised exchange protocol that will allow developers to build payment flows and financial apps. This is indeed quite a competitive market as a number of other such protocols have been launched.
In Brief - Kyber Network is a tool that allows anyone to swap tokens instantly without having to use exchanges. - It allows vendors to accept different types of cryptocurrency while still being paid in their preferred crypto of choice. - It’s built primarily for Ethereum, but any smart-contract based blockchain can incorporate it.
At its core, Kyber is a decentralized way to exchange ETH and different ERC20 tokens instantly–no waiting and no registration needed. To do this Kyber uses a diverse set of liquidity pools, or pools of different crypto assets called “reserves” that any project can tap into or integrate with.
A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go.
All this swapping happens directly on the Ethereum blockchain, meaning every transaction is completely transparent.

1.1.1 WHY BUILD THE KYBER NETWORK?

While crypto currencies were built to be decentralized, many of the exchanges for trading crypto currencies have become centralized affairs. This has led to security vulnerabilities, with many exchanges becoming the victims of hacking and theft.
It has also led to increased fees and costs, and the centralized exchanges often come with slow transfer times as well. In some cases, wallets have been locked and users are unable to withdraw their coins.
Decentralized exchanges have popped up recently to address the flaws in the centralized exchanges, but they have their own flaws, most notably a lack of liquidity, and often times high costs to modify trades in their on-chain order books.

Some of the Integrations with Kyber Protocol
The Kyber Network was formed to provide users with a decentralized exchange that keeps everything right on the blockchain, and uses a reserve system rather than an order book to provide high liquidity at all times. This will allow for the exchange and transfer of any cryptocurrency, even cross exchanges, and costs will be kept at a minimum as well.
The Kyber Network has three guiding design philosophies since the start:
  1. To be most useful the network needs to be platform-agnostic, which allows any protocol or application the ability to take advantage of the liquidity provided by the Kyber Network without any impact on innovation.
  2. The network was designed to make real-world commerce and decentralized financial products not only possible but also feasible. It does this by allowing for instant token exchange across a wide range of tokens, and without any settlement risk.
  3. The Kyber Network was created with ease of integration as a priority, which is why everything runs fully on-chain and fully transparent. Kyber is not only developer-friendly, but is also compatible with a wide variety of systems.

1.1.2 WHO INVENTED KYBER?

Kyber’s founders are Loi Luu, Victor Tran, Yaron Velner — CEO, CTO, and advisor to the Kyber Network.

1.1.3 WHAT DISTINGUISHES KYBER?

Kyber’s mission has always been to integrate with other protocols so they’ve focused on being developer-friendly by providing architecture to allow anyone to incorporate the technology onto any smart-contract powered blockchain. As a result, a variety of different dapps, vendors, and wallets use Kyber’s infrastructure including Set Protocol, bZx, InstaDApp, and Coinbase wallet.
Besides, dapps, vendors, and wallets, Kyber also integrates with other exchanges such as Uniswap — sharing liquidity pools between the two protocols.
A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go.
Limit orders on Kyber allow users to set a specific price in which they would like to exchange a token instead of accepting whatever price currently exists at the time of trading. However, unlike with other exchanges, users never lose custody of their crypto assets during limit orders on Kyber.
The Kyber protocol works by using pools of crypto funds called “reserves”, which currently support over 70 different ERC20 tokens. Reserves are essentially smart contracts with a pool of funds. Different parties with different prices and levels of funding control all reserves. Instead of using order books to match buyers and sellers to return the best price, the Kyber protocol looks at all the reserves and returns the best price among the different reserves. Reserves make money on the “spread” or differences between the buying and selling prices. The Kyber wants any token holder to easily convert one token to another with a minimum of fuss.

1.2 KYBER PROTOCOL

The protocol smart contracts offer a single interface for the best available token exchange rates to be taken from an aggregated liquidity pool across diverse sources. ● Aggregated liquidity pool. The protocol aggregates various liquidity sources into one liquidity pool, making it easy for takers to find the best rates offered with one function call. ● Diverse sources of liquidity. The protocol allows different types of liquidity sources to be plugged into. Liquidity providers may employ different strategies and different implementations to contribute liquidity to the protocol. ● Permissionless. The protocol is designed to be permissionless where any developer can set up various types of reserves, and any end user can contribute liquidity. Implementations need to take into consideration various security vectors, such as reserve spamming, but can be mitigated through a staking mechanism. We can expect implementations to be permissioned initially until the maintainers are confident about these considerations.
The core feature that the Kyber protocol facilitates is the token swap between taker and liquidity sources. The protocol aims to provide the following properties for token trades: ● Instant Settlement. Takers do not have to wait for their orders to be fulfilled, since trade matching and settlement occurs in a single blockchain transaction. This enables trades to be part of a series of actions happening in a single smart contract function. ● Atomicity. When takers make a trade request, their trade either gets fully executed, or is reverted. This “all or nothing” aspect means that takers are not exposed to the risk of partial trade execution. ● Public rate verification. Anyone can verify the rates that are being offered by reserves and have their trades instantly settled just by querying from the smart contracts. ● Ease of integration. Trustless and atomic token trades can be directly and easily integrated into other smart contracts, thereby enabling multiple trades to be performed in a smart contract function.
How each actor works is specified in Section Network Actors. 1. Takers refer to anyone who can directly call the smart contract functions to trade tokens, such as end-users, DApps, and wallets. 2. Reserves refer to anyone who wishes to provide liquidity. They have to implement the smart contract functions defined in the reserve interface in order to be registered and have their token pairs listed. 3. Registered reserves refer to those that will be cycled through for matching taker requests. 4. Maintainers refer to anyone who has permission to access the functions for the adding/removing of reserves and token pairs, such as a DAO or the team behind the protocol implementation. 5. In all, they comprise of the network, which refers to all the actors involved in any given implementation of the protocol.
The protocol implementation needs to have the following: 1. Functions for takers to check rates and execute the trades 2. Functions for the maintainers to registeremove reserves and token pairs 3. Reserve interface that defines the functions reserves needs to implement

1.3 KYBER CORE SMART CONTRACTS

Kyber Core smart contracts is an implementation of the protocol that has major protocol functions to allow actors to join and interact with the network. For example, the Kyber Core smart contracts provide functions for the listing and delisting of reserves and trading pairs by having clear interfaces for the reserves to comply to be able to register to the network and adding support for new trading pairs. In addition, the Kyber Core smart contracts also provide a function for takers to query the best rate among all the registered reserves, and perform the trades with the corresponding rate and reserve. A trading pair consists of a quote token and any other token that the reserve wishes to support. The quote token is the token that is either traded from or to for all trades. For example, the Ethereum implementation of the Kyber protocol uses Ether as the quote token.
In order to search for the best rate, all reserves supporting the requested token pair will be iterated through. Hence, the Kyber Core smart contracts need to have this search algorithm implemented.
The key functions implemented in the Kyber Core Smart Contracts are listed in Figure 2 below. We will visit and explain the implementation details and security considerations of each function in the Specification Section.

1.4 HOW KYBER’S ON-CHAIN PROTOCOL WORKS?

Kyber is the liquidity infrastructure for decentralized finance. Kyber aggregates liquidity from diverse sources into a pool, which provides the best rates for takers such as DApps, Wallets, DEXs, and End users.

1.4.1 PROVIDING LIQUIDITY AS A RESERVE

Anyone can operate a Kyber Reserve to market make for profit and make their tokens available for DApps in the ecosystem. Through an open reserve architecture, individuals, token teams and professional market makers can contribute token assets to Kyber’s liquidity pool and earn from the spread in every trade. These tokens become available at the best rates across DApps that tap into the network, making them instantly more liquid and useful.
MAIN RESERVE TYPES Kyber currently has over 45 reserves in its network providing liquidity. There are 3 main types of reserves that allow different liquidity contribution options to suit the unique needs of different providers. 1. Automated Price Reserves (APR) — Allows token teams and users with large token holdings to have an automated yet customized pricing system with low maintenance costs. Synthetix and Melon are examples of teams that run APRs. 2. Fed Price Reserves (FPR) — Operated by professional market makers that require custom and advanced pricing strategies tailored to their specific needs. Kyber alongside reserves such as OneBit, runs FPRs. 3. Bridge Reserves (BR) — These are specialized reserves meant to bring liquidity from other on-chain liquidity providers like Uniswap, Oasis, DutchX, and Bancor into the network.

1.5 KYBER NETWORK ROLES

There Kyber Network functions through coordination between several different roles and functions as explained below: - Users — This entity uses the Kyber Network to send and receive tokens. A user can be an individual, a merchant, and even a smart contract account. - Reserve Entities — This role is used to add liquidity to the platform through the dynamic reserve pool. Some reserve entities are internal to the Kyber Network, but others may be registered third parties. Reserve entities may be public if the public contributes to the reserves they hold, otherwise they are considered private. By allowing third parties as reserve entities the network adds diversity, which prevents monopolization and keeps exchange rates competitive. Allowing third party reserve entities also allows for the listing of less popular coins with lower volumes. - Reserve Contributors — Where reserve entities are classified as public, the reserve contributor is the entity providing reserve funds. Their incentive for doing so is a profit share from the reserve. - The Reserve Manager — Maintains the reserve, calculates exchange rates and enters them into the network. The reserve manager profits from exchange spreads set by them on their reserves. They can also benefit from increasing volume by accessing the entire Kyber Network. - The Kyber Network Operator — Currently the Kyber Network team is filling the role of the network operator, which has a function to adds/remove Reserve Entities as well as controlling the listing of tokens. Eventually, this role will revert to a proper decentralized governance.

1.6 BASIC TOKEN TRADE

A basic token trade is one that has the quote token as either the source or destination token of the trade request. The execution flow of a basic token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for ETH as an example. The trade happens in a single blockchain transaction. 1. Taker sends 1 ETH to the protocol contract, and would like to receive BAT in return. 2. Protocol contract queries the first reserve for its ETH to BAT exchange rate. 3. Reserve 1 offers an exchange rate of 1 ETH for 800 BAT. 4. Protocol contract queries the second reserve for its ETH to BAT exchange rate. 5. Reserve 2 offers an exchange rate of 1 ETH for 820 BAT. 6. This process goes on for the other reserves. After the iteration, reserve 2 is discovered to have offered the best ETH to BAT exchange rate. 7. Protocol contract sends 1 ETH to reserve 2. 8. The reserve sends 820 BAT to the taker.

1.7 TOKEN-TO-TOKEN TRADE

A token-to-token trade is one where the quote token is neither the source nor the destination token of the trade request. The exchange flow of a token to token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for DAI as an example. The trade happens in a single blockchain transaction. 1. Taker sends 50 BAT to the protocol contract, and would like to receive DAI in return. 2. Protocol contract sends 50 BAT to the reserve offering the best BAT to ETH rate. 3. Protocol contract receives 1 ETH in return. 4. Protocol contract sends 1 ETH to the reserve offering the best ETH to DAI rate. 5. Protocol contract receives 30 DAI in return. 6. Protocol contract sends 30 DAI to the user.

2.KYBER NETWORK CRYSTAL (KNC) TOKEN

Kyber Network Crystal (KNC) is an ERC-20 utility token and an integral part of Kyber Network.
KNC is the first deflationary staking token where staking rewards and token burns are generated from actual network usage and growth in DeFi.
The Kyber Network Crystal (KNC) is the backbone of the Kyber Network. It works to connect liquidity providers and those who need liquidity and serves three distinct purposes. The first of these is to collect transaction fees, and a portion of every fee collected is burned, which keeps KNC deflationary. Kyber Network Crystals (KNC), are named after the crystals in Star Wars used to power light sabers.
The KNC also ensures the smooth operation of the reserve system in the Kyber liquidity since entities must use third-party tokens to buy the KNC that pays for their operations in the network.
KNC allows token holders to play a critical role in determining the incentive system, building a wide base of stakeholders, and facilitating economic flow in the network. A small fee is charged each time a token exchange happens on the network, and KNC holders get to vote on this fee model and distribution, as well as other important decisions. Over time, as more trades are executed, additional fees will be generated for staking rewards and reserve rebates, while more KNC will be burned. - Participation rewards — KNC holders can stake KNC in the KyberDAO and vote on key parameters. Voters will earn staking rewards (in ETH) - Burning — Some of the network fees will be burned to reduce KNC supply permanently, providing long-term value accrual from decreasing supply. - Reserve incentives — KNC holders determine the portion of network fees that are used as rebates for selected liquidity providers (reserves) based on their volume performance.

Finally, the KNC token is the connection between the Kyber Network and the exchanges, wallets, and dApps that leverage the liquidity network. This is a virtuous system since entities are rewarded with referral fees for directing more users to the Kyber Network, which helps increase adoption for Kyber and for the entities using the Network.
And of course there will soon be a fourth and fifth uses for the KNC, which will be as a staking token used to generate passive income, as well as a governance token used to vote on key parameters of the network.
The Kyber Network Crystal (KNC) was released in a September 2017 ICO at a price around $1. There were 226,000,000 KNC minted for the ICO, with 61% sold to the public. The remaining 39% are controlled 50/50 by the company and the founders/advisors, with a 1 year lockup period and 2 year vesting period.
Currently, just over 180 million coins are in circulation, and the total supply has been reduced to 210.94 million after the company burned 1 millionth KNC token in May 2019 and then its second millionth KNC token just three months later.
That means that while it took 15 months to burn the first million KNC, it took just 10 weeks to burn the second million KNC. That shows how rapidly adoption has been growing recently for Kyber, with July 2019 USD trading volumes on the Kyber Network nearly reaching $60 million. This volume has continued growing, and on march 13, 2020 the network experienced its highest daily trading activity of $33.7 million in a 24-hour period.
Currently KNC is required by Reserve Managers to operate on the network, which ensures a minimum amount of demand for the token. Combined with future plans for burning coins, price is expected to maintain an upward bias, although it has suffered along with the broader market in 2018 and more recently during the summer of 2019.
It was unfortunate in 2020 that a beginning rally was cut short by the coronavirus pandemic, although the token has stabilized as of April 2020, and there are hopes the rally could resume in the summer of 2020.

2.1 HOW ARE KNC TOKENS PRODUCED?

The native token of Kyber is called Kyber Network Crystals (KNC). All reserves are required to pay fees in KNC for the right to manage reserves. The KNC collected as fees are either burned and taken out of the total supply or awarded to integrated dapps as an incentive to help them grow.

2.2 HOW DO YOU GET HOLD OF KNC TOKENS?

Kyber Swap can be used to buy ETH directly using a credit card, which can then be used to swap for KNC. Besides Kyber itself, exchanges such as Binance, Huobi, and OKex trade KNC.

2.3 WHAT CAN YOU DO WITH KYBER?

The most direct and basic function of Kyber is for instantly swapping tokens without registering an account, which anyone can do using an Etheruem wallet such as MetaMask. Users can also create their own reserves and contribute funds to a reserve, but that process is still fairly technical one–something Kyber is working on making easier for users in the future.

2.4 THE GOAL OF KYBER THE FUTURE

The goal of Kyber in the coming years is to solidify its position as a one-stop solution for powering liquidity and token swapping on Ethereum. Kyber plans on a major protocol upgrade called Katalyst, which will create new incentives and growth opportunities for all stakeholders in their ecosystem, especially KNC holders. The upgrade will mean more use cases for KNC including to use KNC to vote on governance decisions through a decentralized organization (DAO) called the KyberDAO.
With our upcoming Katalyst protocol upgrade and new KNC model, Kyber will provide even more benefits for stakeholders. For instance, reserves will no longer need to hold a KNC balance for fees, removing a major friction point, and there will be rebates for top performing reserves. KNC holders can also stake their KNC to participate in governance and receive rewards.

2.5 BUYING & STORING KNC

Those interested in buying KNC tokens can do so at a number of exchanges. Perhaps your best bet between the complete list is the likes of Coinbase Pro and Binance. The former is based in the USA whereas the latter is an offshore exchange.
The trading volume is well spread out at these exchanges, which means that the liquidity is not concentrated and dependent on any one exchange. You also have decent liquidity on each of the exchange books. For example, the Binance BTC / KNC books are wide and there is decent turnover. This means easier order execution.
KNC is an ERC20 token and can be stored in any wallet with ERC20 support, such as MyEtherWallet or MetaMask. One interesting alternative is the KyberSwap Android mobile app that was released in August 2019.
It allows for instant swapping of tokens and has support for over 70 different altcoins. It also allows users to set price alerts and limit orders and works as a full-featured Ethereum wallet.

2.6 KYBER KATALYST UPGRADE

Kyber has announced their intention to become the de facto liquidity layer for the Decentralized Finance space, aiming to have Kyber as the single on-chain endpoint used by the majority of liquidity providers and dApp developers. In order to achieve this goal the Kyber Network team is looking to create an open ecosystem that garners trust from the decentralized finance space. They believe this is the path that will lead the majority of projects, developers, and users to choose Kyber for liquidity needs. With that in mind they have recently announced the launch of a protocol upgrade to Kyber which is being called Katalyst.
The Katalyst upgrade will create a stronger ecosystem by creating strong alignments towards a common goal, while also strengthening the incentives for stakeholders to participate in the ecosystem.
The primary beneficiaries of the Katalyst upgrade will be the three major Kyber stakeholders: 1. Reserve managers who provide network liquidity; 2. dApps that connect takers to Kyber; 3. KNC holders.
These stakeholders can expect to see benefits as highlighted below: Reserve Managers will see two new benefits to providing liquidity for the network. The first of these benefits will be incentives for providing reserves. Once Katalyst is implemented part of the fees collected will go to the reserve managers as an incentive for providing liquidity.
This mechanism is similar to rebates in traditional finance, and is expected to drive the creation of additional reserves and market making, which in turn will lead to greater liquidity and platform reach.
Katalyst will also do away with the need for reserve managers to maintain a KNC balance for use as network fees. Instead fees will be automatically collected and used as incentives or burned as appropriate. This should remove a great deal of friction for reserves to connect with Kyber without affecting the competitive exchange rates that takers in the system enjoy. dApp Integrators will now be able to set their own spread, which will give them full control over their own business model. This means the current fee sharing program that shares 30% of the 0.25% fee with dApp developers will go away and developers will determine their own spread. It’s believed this will increase dApp development within Kyber as developers will now be in control of fees.
KNC Holders, often thought of as the core of the Kyber Network, will be able to take advantage of a new staking mechanism that will allow them to receive a portion of network fees by staking their KNC and participating in the KyberDAO.

2.7 COMING KYBERDAO

With the implementation of the Katalyst protocol the KNC holders will be put right at the heart of Kyber. Holders of KNC tokens will now have a critical role to play in determining the future economic flow of the network, including its incentive systems.
The primary way this will be achieved is through KyberDAO, a way in which on-chain and off-chain governance will align to streamline cooperation between the Kyber team, KNC holders, and market participants.
The Kyber Network team has identified 3 key areas of consideration for the KyberDAO: 1. Broad representation, transparent governance and network stability 2. Strong incentives for KNC holders to maintain their stake and be highly involved in governance 3. Maximizing participation with a wide range of options for voting delegation
Interaction between KNC Holders & Kyber
This means KNC holders have been empowered to determine the network fee and how to allocate the fees to ensure maximum network growth. KNC holders will now have three fee allocation options to vote on: - Voting Rewards: Immediate value creation. Holders who stake and participate in the KyberDAO get their share of the fees designated for rewards. - Burning: Long term value accrual. The decreasing supply of KNC will improve the token appreciation over time and benefit those who did not participate. - Reserve Incentives:Value creation via network growth. By rewarding Kyber reserve managers based on their performance, it helps to drive greater volume, value, and network fees.

2.8 TRANSPARENCY AND STABILITY

The design of the KyberDAO is meant to allow for the greatest network stability, as well as maximum transparency and the ability to quickly recover in emergency situations. Initally the Kyber team will remain as maintainers of the KyberDAO. The system is being developed to be as verifiable as possible, while still maintaining maximum transparency regarding the role of the maintainer in the DAO.
Part of this transparency means that all data and processes are stored on-chain if feasible. Voting regarding network fees and allocations will be done on-chain and will be immutable. In situations where on-chain storage or execution is not feasible there will be a set of off-chain governance processes developed to ensure all decisions are followed through on.

2.9 KNC STAKING AND DELEGATION

Staking will be a new addition and both staking and voting will be done in fixed periods of times called “epochs”. These epochs will be measured in Ethereum block times, and each KyberDAO epoch will last roughly 2 weeks.
This is a relatively rapid epoch and it is beneficial in that it gives more rapid DAO conclusion and decision-making, while also conferring faster reward distribution. On the downside it means there needs to be a new voting campaign every two weeks, which requires more frequent participation from KNC stakeholders, as well as more work from the Kyber team.
Delegation will be part of the protocol, allowing stakers to delegate their voting rights to third-party pools or other entities. The pools receiving the delegation rights will be free to determine their own fee structure and voting decisions. Because the pools will share in rewards, and because their voting decisions will be clearly visible on-chain, it is expected that they will continue to work to the benefit of the network.

3. TRADING

After the September 2017 ICO, KNC settled into a trading price that hovered around $1.00 (decreasing in BTC value) until December. The token has followed the trend of most other altcoins — rising in price through December and sharply declining toward the beginning of January 2018.
The KNC price fell throughout all of 2018 with one exception during April. From April 6th to April 28th, the price rose over 200 percent. This run-up coincided with a blog post outlining plans to bring Bitcoin to the Ethereum blockchain. Since then, however, the price has steadily fallen, currently resting on what looks like a $0.15 (~0.000045 BTC) floor.
With the number of partners using the Kyber Network, the price may rise as they begin to fully use the network. The development team has consistently hit the milestones they’ve set out to achieve, so make note of any release announcements on the horizon.

4. COMPETITION

The 0x project is the biggest competitor to Kyber Network. Both teams are attempting to enter the decentralized exchange market. The primary difference between the two is that Kyber performs the entire exchange process on-chain while 0x keeps the order book and matching off-chain.
As a crypto swap exchange, the platform also competes with ShapeShift and Changelly.
