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.

Founded by HDR Global Trading Limited (which in turn was founded by former bankers Arthur Hayes, Samuel Reed and Ben Delo) in 2014, BitMEX is a trading platform operating around the world and registered in the Seychelles.
Meaning Bitcoin Mercantile Exchange, BitMEX is one of the largest Bitcoin trading platforms currently operating, with a daily trading volume of over 35,000 BTC and over 540,000 accesses monthly and a trading history of over $34 billion worth of Bitcoin since its inception.

https://preview.redd.it/coenpm4k3cc41.jpg?width=808&format=pjpg&auto=webp&s=8832dcafa5bd615b511bbeb6118ef43d73ed785e
Unlike many other trading exchanges, BitMEX only accepts deposits through Bitcoin, which can then be used to purchase a variety of other cryptocurrencies. BitMEX specialises in sophisticated financial operations such as margin trading, which is trading with leverage. Like many of the exchanges that operate through cryptocurrencies, BitMEX is currently unregulated in any jurisdiction.

How to Sign Up to BitMEX

In order to create an account on BitMEX, users first have to register with the website. Registration only requires an email address, the email address must be a genuine address as users will receive an email to confirm registration in order to verify the account. Once users are registered, there are no trading limits. Traders must be at least 18 years of age to sign up.
https://preview.redd.it/0v13qoil3cc41.jpg?width=808&format=pjpg&auto=webp&s=e6134bc089c4e352dce10d754dc84ff11a4c7994
However, it should be noted that BitMEX does not accept any US-based traders and will use IP checks to verify that users are not in the US. While some US users have bypassed this with the use of a VPN, it is not recommended that US individuals sign up to the BitMEX service, especially given the fact that alternative exchanges are available to service US customers that function within the US legal framework.
How to Use BitMEX
BitMEX allows users to trade cryptocurrencies against a number of fiat currencies, namely the US Dollar, the Japanese Yen and the Chinese Yuan. BitMEX allows users to trade a number of different cryptocurrencies, namely Bitcoin, Bitcoin Cash, Dash, Ethereum, Ethereum Classic, Litecoin, Monero, Ripple, Tezos and Zcash.
The trading platform on BitMEX is very intuitive and easy to use for those familiar with similar markets. However, it is not for the beginner. The interface does look a little dated when compared to newer exchanges like Binance and Kucoin’s.
Once users have signed up to the platform, they should click on Trade, and all the trading instruments will be displayed beneath.
Clicking on the particular instrument opens the orderbook, recent trades, and the order slip on the left. The order book shows three columns – the bid value for the underlying asset, the quantity of the order, and the total USD value of all orders, both short and long.
The widgets on the trading platform can be changed according to the user’s viewing preferences, allowing users to have full control on what is displayed. It also has a built in feature that provides for TradingView charting. This offers a wide range of charting tool and is considered to be an improvement on many of the offering available from many of its competitors.

Once trades are made, all orders can be easily viewed in the trading platform interface. There are tabs where users can select their Active Orders, see the Stops that are in place, check the Orders Filled (total or partially) and the trade history. On the Active Orders and Stops tabs, traders can cancel any order, by clicking the “Cancel” button. Users also see all currently open positions, with an analysis if it is in the black or red.
BitMEX uses a method called auto-deleveraging which BitMEX uses to ensure that liquidated positions are able to be closed even in a volatile market. Auto-deleveraging means that if a position bankrupts without available liquidity, the positive side of the position deleverages, in order of profitability and leverage, the highest leveraged position first in queue. Traders are always shown where they sit in the auto-deleveraging queue, if such is needed.
Although the BitMEX platform is optimized for mobile, it only has an Android app (which is not official). There is no iOS app available at present. However, it is recommended that users use it on the desktop if possible.
BitMEX offers a variety of order types for users:
  • Limit Order (the order is fulfilled if the given price is achieved);
  • Market Order (the order is executed at current market price);
  • Stop Limit Order (like a stop order, but allows users to set the price of the Order once the Stop Price is triggered);
  • Stop Market Order (this is a stop order that does not enter the order book, remain unseen until the market reaches the trigger);
  • Trailing Stop Order (it is similar to a Stop Market order, but here users set a trailing value that is used to place the market order);
  • Take Profit Limit Order (this can be used, similarly to a Stop Order, to set a target price on a position. In this case, it is in respect of making gains, rather than cutting losses);
  • Take Profit Market Order (same as the previous type, but in this case, the order triggered will be a market order, and not a limit one)
The exchange offers margin trading in all of the cryptocurrencies displayed on the website. It also offers to trade with futures and derivatives – swaps.

Futures and Swaps

A futures contract is an agreement to buy or sell a given asset in the future at a predetermined price. On BitMEX, users can leverage up to 100x on certain contracts.
Perpetual swaps are similar to futures, except that there is no expiry date for them and no settlement. Additionally, they trade close to the underlying reference Index Price, unlike futures, which may diverge substantially from the Index Price.
BitMEX also offers Binary series contracts, which are prediction-based contracts which can only settle at either 0 or 100. In essence, the Binary series contracts are a more complicated way of making a bet on a given event.
The only Binary series betting instrument currently available is related to the next 1mb block on the Bitcoin blockchain. Binary series contracts are traded with no leverage, a 0% maker fee, a 0.25% taker fee and 0.25% settlement fee.

Bitmex Leverage

BitMEX allows its traders to leverage their position on the platform. Leverage is the ability to place orders that are bigger than the users’ existing balance. This could lead to a higher profit in comparison when placing an order with only the wallet balance. Trading in such conditions is called “Margin Trading.”
There are two types of Margin Trading: Isolated and Cross-Margin. The former allows the user to select the amount of money in their wallet that should be used to hold their position after an order is placed. However, the latter provides that all of the money in the users’ wallet can be used to hold their position, and therefore should be treated with extreme caution.
https://preview.redd.it/eg4qk9qr3cc41.jpg?width=808&format=pjpg&auto=webp&s=c3ca8cdf654330ce53e8138d774e72155acf0e7e
The BitMEX platform allows users to set their leverage level by using the leverage slider. A maximum leverage of 1:100 is available (on Bitcoin and Bitcoin Cash). This is quite a high level of leverage for cryptocurrencies, with the average offered by other exchanges rarely exceeding 1:20.

BitMEX Fees

For traditional futures trading, BitMEX has a straightforward fee schedule. As noted, in terms of leverage offered, BitMEX offers up to 100% leverage, with the amount off leverage varying from product to product.
However, it should be noted that trading at the highest leverages is sophisticated and is intended for professional investors that are familiar with speculative trading. The fees and leverage are as follows:
https://preview.redd.it/wvhiepht3cc41.jpg?width=730&format=pjpg&auto=webp&s=0617eb894c13d3870211a01d51af98561907cb99

However, there are additional fees for hidden / iceberg orders. A hidden order pays the taker fee until the entire hidden quantity is completely executed. Then, the order will become normal, and the user will receive the maker rebate for the non-hidden amount.

Deposits and Withdrawals

BitMEX does not charge fees on deposits or withdrawals. However, when withdrawing Bitcoin, the minimum Network fee is based on blockchain load. The only costs therefore are those of the banks or the cryptocurrency networks.
As noted previously, BitMEX only accepts deposits in Bitcoin and therefore Bitcoin serves as collateral on trading contracts, regardless of whether or not the trade involves Bitcoin.
The minimum deposit is 0.001 BTC. There are no limits on withdrawals, but withdrawals can also be in Bitcoin only. To make a withdrawal, all that users need to do is insert the amount to withdraw and the wallet address to complete the transfer.
https://preview.redd.it/xj1kbuew3cc41.jpg?width=808&format=pjpg&auto=webp&s=68056f2247001c63e89c880cfbb75b2f3616e8fe
Deposits can be made 24/7 but withdrawals are processed by hand at a recurring time once per day. The hand processed withdrawals are intended to increase the security levels of users’ funds by providing extra time (and email notice) to cancel any fraudulent withdrawal requests, as well as bypassing the use of automated systems & hot wallets which may be more prone to compromise.

Supported Currencies

BitMEX operates as a crypto to crypto exchange and makes use of a Bitcoin-in/Bitcoin-out structure. Therefore, platform users are currently unable to use fiat currencies for any payments or transfers, however, a plus side of this is that there are no limits for trading and the exchange incorporates trading pairs linked to the US Dollar (XBT), Japanese Yen (XBJ), and Chinese Yuan (XBC).
BitMEX supports the following cryptocurrencies:
  • Bitcoin (XBT)
  • Bitcoin Cash (BCH)
  • Ethereum (ETH)
  • Ethereum Classic (ETC)
  • Litecoin (LTC)
  • Ripple Token (XRP)
  • Monero (XMR)
  • Dash (DASH)
  • Zcash (ZEC)
  • Cardano (ADA)
  • Tron (TRX)
  • EOS Token (EOS)
BitMEX also offers leverage options on the following coins:
  • 5x: Zcash (ZEC)
  • 20x : Ripple (XRP),Bitcoin Cash (BCH), Cardano (ADA), EOS Token (EOS), Tron (TRX)
  • 25x: Monero (XMR)
  • 33x: Litecoin (LTC)
  • 50x: Ethereum (ETH)
  • 100x: Bitcoin (XBT), Bitcoin / Yen (XBJ), Bitcoin / Yuan (XBC)

Trading Technologies International Partnership

HDR Global Trading, the company which owns BitMEX, has recently announced a partnership with Trading Technologies International, Inc. (TT), a leading international high-performance trading software provider.
The TT platform is designed specifically for professional traders, brokers, and market-access providers, and incorporates a wide variety of trading tools and analytical indicators that allow even the most advanced traders to customize the software to suit their unique trading styles. The TT platform also provides traders with global market access and trade execution through its privately managed infrastructure and the partnership will see BitMEX users gaining access to the trading tools on all BitMEX products, including the popular XBT/USD Perpetual Swap pairing.

The BitMEX Insurance Fund

The ability to trade on leverage is one of the exchange’s main selling points and offering leverage and providing the opportunity for traders to trade against each other may result in a situation where the winners do not receive all of their expected profits. As a result of the amounts of leverage involved, it’s possible that the losers may not have enough margin in their positions to pay the winners.
Traditional exchanges like the Chicago Mercantile Exchange (CME) offset this problem by utilizing multiple layers of protection and cryptocurrency trading platforms offering leverage cannot currently match the levels of protection provided to winning traders.
In addition, cryptocurrency exchanges offering leveraged trades propose a capped downside and unlimited upside on a highly volatile asset with the caveat being that on occasion, there may not be enough funds in the system to pay out the winners.
To help solve this problem, BitMEX has developed an insurance fund system, and when a trader has an open leveraged position, their position is forcefully closed or liquidated when their maintenance margin is too low.
Here, a trader’s profit and loss does not reflect the actual price their position was closed on the market, and with BitMEX when a trader is liquidated, their equity associated with the position drops down to zero.
In the following example, the trader has taken a 100x long position. In the event that the mark price of Bitcoin falls to $3,980 (by 0.5%), then the position gets liquidated with the 100 Bitcoin position needing to be sold on the market.
This means that it does not matter what price this trade executes at, namely if it’s $3,995 or $3,000, as from the view of the liquidated trader, regardless of the price, they lose all the equity they had in their position, and lose the entire one Bitcoin.
https://preview.redd.it/wel3rka04cc41.png?width=669&format=png&auto=webp&s=3f93dac2d3b40aa842d281384113d2e26f25947e
Assuming there is a fully liquid market, the bid/ask spread should be tighter than the maintenance margin. Here, liquidations manifest as contributions to the insurance fund (e.g. if the maintenance margin is 50bps, but the market is 1bp wide), and the insurance fund should rise by close to the same amount as the maintenance margin when a position is liquidated. In this scenario, as long as healthy liquid markets persist, the insurance fund should continue its steady growth.
The following graphs further illustrate the example, and in the first chart, market conditions are healthy with a narrow bid/ask spread (just $2) at the time of liquidation. Here, the closing trade occurs at a higher price than the bankruptcy price (the price where the margin balance is zero) and the insurance fund benefits.
Illustrative example of an insurance contribution – Long 100x with 1 BTC collateral
https://preview.redd.it/is89ep924cc41.png?width=699&format=png&auto=webp&s=f0419c68fe88703e594c121b5b742c963c7e2229
(Note: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,978, representing $1 of slippage compared to the $3,979 bid price at the time of liquidation.)
The second chart shows a wide bid/ask spread at the time of liquidation, here, the closing trade takes place at a lower price than the bankruptcy price, and the insurance fund is used to make sure that winning traders receive their expected profits.
This works to stabilize the potential for returns as there is no guarantee that healthy market conditions can continue, especially during periods of heightened price volatility. During these periods, it’s actually possible that the insurance fund can be used up than it is built up.
Illustrative example of an insurance depletion – Long 100x with 1 BTC collateral
https://preview.redd.it/vb4mj3n54cc41.png?width=707&format=png&auto=webp&s=0c63b7c99ae1c114d8e3b947fb490e9144dfe61b
(Notes: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,800, representing $20 of slippage compared to the $3,820 bid price at the time of liquidation.)
The exchange declared in February 2019, that the BitMEX insurance fund retained close to 21,000 Bitcoin (around $70 million based on Bitcoin spot prices at the time).
This figure represents just 0.007% of BitMEX’s notional annual trading volume, which has been quoted as being approximately $1 trillion. This is higher than the insurance funds as a proportion of trading volume of the CME, and therefore, winning traders on BitMEX are exposed to much larger risks than CME traders as:
  • BitMEX does not have clearing members with large balance sheets and traders are directly exposed to each other.
  • BitMEX does not demand payments from traders with negative account balances.
  • The underlying instruments on BitMEX are more volatile than the more traditional instruments available on CME.
Therefore, with the insurance fund remaining capitalized, the system effectively with participants who get liquidated paying for liquidations, or a losers pay for losers mechanism.
This system may appear controversial as first, though some may argue that there is a degree of uniformity to it. It’s also worth noting that the exchange also makes use of Auto Deleveraging which means that on occasion, leveraged positions in profit can still be reduced during certain time periods if a liquidated order cannot be executed in the market.
More adventurous traders should note that while the insurance fund holds 21,000 Bitcoin, worth approximately 0.1% of the total Bitcoin supply, BitMEX still doesn’t offer the same level of guarantees to winning traders that are provided by more traditional leveraged trading platforms.
Given the inherent volatility of the cryptocurrency market, there remains some possibility that the fund gets drained down to zero despite its current size. This may result in more successful traders lacking confidence in the platform and choosing to limit their exposure in the event of BitMEX being unable to compensate winning traders.

How suitable is BitMEX for Beginners?

BitMEX generates high Bitcoin trading levels, and also attracts good levels of volume across other crypto-to-crypto transfers. This helps to maintain a buzz around the exchange, and BitMEX also employs relatively low trading fees, and is available round the world (except to US inhabitants).
This helps to attract the attention of people new to the process of trading on leverage and when getting started on the platform there are 5 main navigation Tabs to get used to:
  • **Trade:**The trading dashboard of BitMEX. This tab allows you to select your preferred trading instrument, and choose leverage, as well as place and cancel orders. You can also see your position information and view key information in the contract details.
  • **Account:**Here, all your account information is displayed including available Bitcoin margin balances, deposits and withdrawals, and trade history.
  • **Contracts:**This tab covers further instrument information including funding history, contract sizes; leverage offered expiry, underlying reference Price Index data, and other key features.
  • **References:**This resource centre allows you to learn about futures, perpetual contracts, position marking, and liquidation.
  • **API:**From here you can set up an API connection with BitMEX, and utilize the REST API and WebSocket API.
BitMEX also employs 24/7 customer support and the team can also be contacted on their Twitter and Reddit accounts.
In addition, BitMEX provides a variety of educational resources including an FAQ section, Futures guides, Perpetual Contracts guides, and further resources in the “References” account tab.
For users looking for more in depth analysis, the BitMEX blog produces high level descriptions of a number of subjects and has garnered a good reputation among the cryptocurrency community.
Most importantly, the exchange also maintains a testnet platform, built on top of testnet Bitcoin, which allows anyone to try out programs and strategies before moving on to the live exchange.
This is crucial as despite the wealth of resources available, BitMEX is not really suitable for beginners, and margin trading, futures contracts and swaps are best left to experienced, professional or institutional traders.
Margin trading and choosing to engage in leveraged activity are risky processes and even more advanced traders can describe the process as a high risk and high reward “game”. New entrants to the sector should spend a considerable amount of time learning about margin trading and testing out strategies before considering whether to open a live account.

Is BitMEX Safe?

BitMEX is widely considered to have strong levels of security. The platform uses multi-signature deposits and withdrawal schemes which can only be used by BitMEX partners. BitMEX also utilises Amazon Web Services to protect the servers with text messages and two-factor authentication, as well as hardware tokens.
BitMEX also has a system for risk checks, which requires that the sum of all account holdings on the website must be zero. If it’s not, all trading is immediately halted. As noted previously, withdrawals are all individually hand-checked by employees, and private keys are never stored in the cloud. Deposit addresses are externally verified to make sure that they contain matching keys. If they do not, there is an immediate system shutdown.
https://preview.redd.it/t04qs3484cc41.jpg?width=808&format=pjpg&auto=webp&s=a3b106cbc9116713dcdd5e908c00b555fd704ee6
In addition, the BitMEX trading platform is written in kdb+, a database and toolset popular amongst major banks in high frequency trading applications. The BitMEX engine appears to be faster and more reliable than some of its competitors, such as Poloniex and Bittrex.
They have email notifications, and PGP encryption is used for all communication.
The exchange hasn’t been hacked in the past.

How Secure is the platform?

As previously mentioned, BitMEX is considered to be a safe exchange and incorporates a number of security protocols that are becoming standard among the sector’s leading exchanges. In addition to making use of Amazon Web Services’ cloud security, all the exchange’s systems can only be accessed after passing through multiple forms of authentication, and individual systems are only able to communicate with each other across approved and monitored channels.
Communication is also further secured as the exchange provides optional PGP encryption for all automated emails, and users can insert their PGP public key into the form inside their accounts.
Once set up, BitMEX will encrypt and sign all the automated emails sent by you or to your account by the [[email protected]](mailto:[email protected]) email address. Users can also initiate secure conversations with the support team by using the email address and public key on the Technical Contact, and the team have made their automated system’s PGP key available for verification in their Security Section.
The platform’s trading engine is written in kdb+, a database and toolset used by leading financial institutions in high-frequency trading applications, and the speed and reliability of the engine is also used to perform a full risk check after every order placement, trade, settlement, deposit, and withdrawal.
All accounts in the system must consistently sum to zero, and if this does not happen then trading on the platform is immediately halted for all users.
With regards to wallet security, BitMEX makes use of a multisignature deposit and withdrawal scheme, and all exchange addresses are multisignature by default with all storage being kept offline. Private keys are not stored on any cloud servers and deep cold storage is used for the majority of funds.
Furthermore, all deposit addresses sent by the BitMEX system are verified by an external service that works to ensure that they contain the keys controlled by the founders, and in the event that the public keys differ, the system is immediately shut down and trading halted. The exchange’s security practices also see that every withdrawal is audited by hand by a minimum of two employees before being sent out.

BitMEX Customer Support

The trading platform has a 24/7 support on multiple channels, including email, ticket systems and social media. The typical response time from the customer support team is about one hour, and feedback on the customer support generally suggest that the customer service responses are helpful and are not restricted to automated responses.
https://preview.redd.it/8k81zl0a4cc41.jpg?width=808&format=pjpg&auto=webp&s=e30e5b7ca93d2931f49e2dc84025f2fda386eab1
The BitMEX also offers a knowledge base and FAQs which, although they are not necessarily always helpful, may assist and direct users towards the necessary channels to obtain assistance.
BitMEX also offers trading guides which can be accessed here

Conclusion

There would appear to be few complaints online about BitMEX, with most issues relating to technical matters or about the complexities of using the website. Older complaints also appeared to include issues relating to low liquidity, but this no longer appears to be an issue.
BitMEX is clearly not a platform that is not intended for the amateur investor. The interface is complex and therefore it can be very difficult for users to get used to the platform and to even navigate the website.
However, the platform does provide a wide range of tools and once users have experience of the platform they will appreciate the wide range of information that the platform provides.

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Ethermint
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.

IBC

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/qr4k6cxtmba31.png?width=1100&format=png&auto=webp&s=d79871767ced4bcb0b2632cc137c118f70c3863a
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.

see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.

Ethermint

Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

Profit Trailer : A Newbie Guide to Setting up your first Crypto Trading Bot!

Hello Everyone! Unless you’ve been living under a rock, you’ve likely heard all about BitCoin, LiteCoin, Ethereum and a whole host cryptocurrencies. As cryptomining profitability fades underneath increasing difficulties and the rising cost of mining machines, the world is dazzled by the utterly insane profit margins to be made in TRADING cryptocurrencies. This typically leads the average Joe to look into and, likely, invest some money into the cryptocurrency market. And, as time progresses (especially if profits are being made), one inevitably must make a choice to use a trading bot or not.
Now, I’m not trying to sell you one way or the other. My goal here is to take one of the newest and seemingly most profitable of the numerous trading bots out there, Profit Trailer, and break down getting the bot installed and running. There are numerous guides to Profit Trailer Installation and all of them are good. Crypto Gnome has some excellent information at https://github.com/CryptoGnome/Profit-Trailer-Settings/wiki/Setup-Guide. I’m not trying to knock him or anyone else with a guide out there. BUT………….
There are a few things that, in the course of installing this bot for a family member who has gotten on the crypto wagon in a big way, I noticed were lacking in the main set of guides. This being that not one of them had been designed with the true noob in mind. Each assumed a level of knowledge and discourse that can ( and would) leave a newbie cursing the fact they just spent .03 of a Bitcoin on something that refuses to even start.
Anyway, the point is, if you don’t have a tech savvy person handy, you could be left with, at best, the program downloaded but unable to start it or at worst, out a nice chunk of your crypto because of failing to understand EXACTLY what is needed to make the bot operate. Any suggestions on how to make this guide more complete, such as adding specific exchange instructions would be most appreciated.
Have an account at either Bittrex, Poloniex or Binance ACTIVE! I have read horror stories regarding buying this bot and installing it without having your account open and logged into. Just in case there is truth to them, better to be safe than sorry. Open your account of choice ( we used Binance so that is the exchange that this guide refers to. ) Use the account interface to create TWO(2) sets of API keys. One will be public, one will be secret in each set. You will notice that, at least on Binance, that each set of keys will have 2 permissions checked and one, withdrawals, unchecked. This is as it should be. If for some reason the withdrawals permission is checked, delete the key and start over. I would suggest that, for ease of use sake, you label each of the sets of keys. The first should be labeled (yourexchange)Default and the second should be labeled(yourexchange)Trading. This will help you recognize which keys are which later in the setup process. Copy these into a Notepad file, Word file, write them on your bedroom walls in blood, just keep BOTH SETS OF THESE API KEYS SAFE! Anyone with these keys has access to your exchange account. The first key will be initially used when you buy the Profit Trailer bot. The others will be used when you set up Profit Trailer. Ensure that you have JAVA 8 installed and running on your computer. It is extremely important that it be JAVA 8 and not 9. Profit Trailer WILL NOT WORK WITH THE JAVA 9 JRE. This problem was likely the biggest hurdle with Profit Trailer until I realized what was happening. Download and install Notepad++. Very Important. Some guides make it sound like you can do the settings changes on a regular NotePad file. This may be true, but Notepad++ is an actual IDE (software writing program for the uninitiated) that will give you the same view that all the guys in their YouTube Videos have up when they discuss their settings. Just saying guys, you’ve got people who, while they might know how to trade, might not know squat about IDE’s and their function. Buy the bot. This can be accomplished at https://profittrailer.com/pt/CryptoGnome/ At check out, you will be asked for the FIRST of the API keys you created. This will be the, first PUBLIC key you created. Pay for the bot. Wait for BitCoin to go from wallet to Profit Trailer creators. Have a beer….Smoke a cigarette….watch a movie. Seriously, you’re gonna be waiting awhile. One good idea while you spend hours waiting for the license key to be sent to you is to ensure that, if you have a newly created exchange account, you should place some cryptocurrency/money in the account…otherwise you’ve got another wait. Most guides say to next get a VPS(Virtual Private Server or Cloud Server). I was unable to get a VPS enabled at the time of this installation, so I will be posting another article regarding that process as soon as I can get it up and running on this installation. UPDATE We now have a Windows VPS running. You can visit Profit Trailer And You: A Newbie Guide To Setting Up Profit Trailer Part 2: Windows VPS here. Get Profit trailer Up and Running!!!! Here’s what you’ve been waiting for and trust me, all the other “prep stuff” will make this part a whole lot smoother. First, go to https://github.com/taniman/profit-trailereleases download the latest version of Profit Trailer. Next, unzip the files and navigate to the new folder. Open the file named application.properties with Notepad++ and then stare at it. I mean… really stare at it. Scary huh? Looks like you’re about to start coding the next Destiny game doesn’t it? Relax. this is a simple IDE that is giving you a series of settings that have to be adjusted manually instead of using a graphics user interface like the ones we’ve all grown to know and love. What you really need to know is what you are looking at. You’re going to see things like “trading.exchange” and “default_apiKey”. Each of these lines will have an equals sign on the end of them. Concentrate on what’s on the right side of the equals sign, cause that’s where your info is going to go. Remember those API keys you made? Well, here’s where they go.
Update these settings:
trading.exchange = THE EXCHANGE YOU ARE USING e.g. BITTREX (This MUST BE IN ALL CAPS. using lower case letter will give you an error code on startup)
default_apiKey = THE FIRST API KEY YOU CREATED (The key you labeled (yourexchange)Default )
default_apiSecret = THE FIRST SECRET KEY YOU CREATED
trading_apiKey = THE SECOND API KEY YOU CREATED (The key you labeled (yourexchange)Trading )
trading_apiSecret = THE SECOND SECRET KEY YOU CREATED
server.password = PASSWORD HERE (This is a password you create here. it is not tied to any other account)
Click save
You with me so far? Keep in mind that, so far the bot IS NOT RUNNING. we haven’t turned on anything yet, so don’t worry.
Most of the other guides say to start the bot up at this point and I would tend to agree, except you may want to look at the default settings in the pairs and DCA files to ensure that they are set the way you want them. DCA settings are a huge factor in Profit Trailer and I would suggest watching several videos regarding them. I do not claim to be a crypto expert and do not pretend to understand all the terms. The Profit Trailer Wiki at https://wiki.profittrailer.io/doku.php/dca.properties has in depth articles dealing with each of the settings and I suggest getting very familiar with them and understanding exactly what each does before turning the bot on.
Ok, with that being said, if you feel like your settings are just the way you want them, open up the pairs.properties file in Notepad++ and change “ALL_trading_enabled=false” to “ALL_trading_enabled=true” and save the file. Next you will want to click ‘run’ on the ProfitTrailer.cmd file. This will actually start the bot and will open an old style black Windows command line window. Ignore this as it is just the bot starting up, not where you will see what the bot is doing and open your web browser and enter http://localhost:8081/monitoring in the URL field. This will bring up a login page. Use the Password you created in the application.properties file here. This opens the web monitoring dashboard for your bot.
Again, I cannot stress enough the importance of following each step and understanding what each of the settings in Profit Trailer are and what they do. There are several important safety valves in Profit Trailer to keep the bot from chewing through your crypto like cookie monster on a 3 day bender.
One is “ALL_max_cost = x.xxxxx” in pairs.properties. This sets the amount of coin, in BitCoin, that the bot will use for trading. Just because you have have 1.5 BTC in your exchange account doesn’t mean you’ve gotta let the bot play with it all. “ALL_min_buy_balance = x.xx” in the pairs.propertiesfile will accomplish the same thing, just specifying an amount in the account that the bot will not take the account below. There are several important safety triggers in the DCA files as well, one being “min_buy_balance = x.xx” which will keep a specified minimum of BTC in your account, below which NO DCA buys will occur. This is an important distinction from the “ALL_min_buy_balance = x.xx” found in the pairs.properties files; DCA buys will STILL OCCUR even if the account is at or below the minimum specified in the pairs.properties file. Confused yet? It makes sense really, but if you’re like me, DCA really doesn’t mean anything to you. ( It’s Dollar Cost Averaging and it’s a profit mechanism used by Profit Trailer) What it really means is that, if you don’t know or understand what you are doing, it can cause big problems trading. Use your safety triggers and brush up on your trading terms cause soon you’ll be hip deep in EMAGains and Dust Bags…..whatever that means.
Any info on other exchange procedures with reagrds to setting up Profit Trailer would be greatly appreciated. I am not affiliated with or paid by any exchange, developer or site.

I created a Free Tax Calculator and subtly promote NANO in it. Please Read!

Edit: The "historical Price Download", is not working anymore as bandwidth on Github LFS is limited (I didnt know that). I am reuploading it on Google Drive after work :))
Hi together! I created a Free Python Script to process your trade histories.
I am a big NANO supporter and I subtly promote NANO in it :P (Check out the Logo and Screenshots) As I could only use my transaction histories I need your help.
Please follow the HOWTO (below) and try to calculate your profits! If you run into any problems (and there will be bugs!) or if you need more exchanges write it in the comments and I will add them! (I could only integrate the ones I use, cause I only got csv files from there)
The tool is working fine for me and I could perfectly calculate my profit, payed fees and last buy times to determine the 12 month holding time.

The code is not that complex, so take a look at it and feel free to add, correct or modify stuff and make sure to push it :)

CryptoProfIT (Alpha Version)

https://github.com/LucidSkyWalkeCryptoProfIT/blob/masteREADME.md
The profit result can be used to calculate the tax on your crypto. The output are two csv-files. Example Screenshots can be found below.
The output files contain: - Sorted full trade history (converts all exchange exports to the same formatting) - Fees per Trade (inklusive Overall Payed fees) - Profit per trade (Overall profit. This can be used to easily calculate your personal capital taxes) - Profit can be calculated in EUR or USD. (Data from European Central Bank) - Amount of your Cryptocurrencies - Display the different BUY-INs by amount and date. So you can control the 12 month holding period.
Supported Exchanges: Binance, Bitfinex, Bittrex, Kraken, Mercatox, Poloniex, Costum*
*A dummy file is included that can be used to easily add trades of other exchanges. If you give me a csv-file export from other exchanges (you can modify the digits for privacy) I will add them.
PLEASE READ: I wrote this tool to calculate my taxes and it did the job fine! Nevertheless it is not well tested yet. If you run into trouble, please write an issue and I will fix it! Thank you :)

Screenshots

Screenshot1 Screenshot of the output.csv. The data of all exchanges is formatted in its specific ways and displayed in a uniform style. Type always refers to the first token of the pair! (First transaction shows buying XRP by BTC) Base Price always refers to the second token of the pair. Base Price in USD shows the price of the second token in USD.
Screenshot2 Screenshot of the holding_output.csv. This file can be used to specify your remaining holding times, as Capital gains do not need to be taxed in many countries after 12 month The picture shows (in red), that the first of the remaining ETH were bought on 2017-06-02, meaning that this amount is tax-free one year later. The blue frame shows the date for the next tokens...
Screenshot3 Console output of the Python script (Not my real data ;)

Requirements

For now, there is no Gui so you have to use the python script. If some dev likes to help, making a gui or a brython version would be neat.

HOWTO:

Setting up Python:

Using the script:

* This package uses the European Central Bank as source for EUUSD to get the historical exchange rates. Author: Alex Prengère Home Page: https://github.com/alexprengere/currencyconverter

Fork information:

A tax accountant told me, you need to pay taxes on the profit of your received forked coins as soon as you get them. Therefore a "dummy" trade needs to be manually added to one of the csv export files in "trade_history_files". * Add a "Buy" transaction at the moment you reveived the coins. (with price "0") * Add a "Sell" transaction a few seconds later (price = initial price of forked coin) you made the inital profit. * Add a "Buy" transaction a few seconds later than before (price = initial price) Because you know still got the coins Simplifing this could be a feature in a future version...

Using the dummy-file:

You can use this file to add trades from exchanges that do not provide trade history exports. Important: You have to use the same formatting like the sample data in the file. Ensure the right date formatting, and use "." for decimals.

Other Information:

Disclaimer:

I wrote this tool to calculate my taxes and thought I share it. I do not guarantee that the results are 100% accurate, but the script might help you getting a well formatted output csv you can work with.

CryptoProfIT: Free Tool for Tax Calculation. (Community Project, Please Read!)

Hi together! I created a Free Python Script to process your trade histories.
It would be awesome if this would become a community project which everybody involved in Cryptos can use for FREE.
The logic should be ready and next steps would be: -testing -creating gui or webapplication -adding features
Follow the HOWTO (below) and to calculate your profits etc.! If you run into any problems or if you need more exchanges write it in the comments and I will add them! (I could only integrate the ones I use, cause I only got csv files from there)
The tool is working fine for me and I could perfectly calculate my profit, payed fees and last buy times to determine the 12 month holding time.

The code is not that complex, so take a look at it and feel free to add, correct or modify stuff and make sure to push it :)

CryptoProfIT (Alpha Version)

https://github.com/LucidSkyWalkeCryptoProfIT/blob/masteREADME.md
The profit result can be used to calculate the tax on your crypto. The output are two csv-files. Example Screenshots can be found below.
The output files contain: - Sorted full trade history (converts all exchange exports to the same formatting) - Fees per Trade (inklusive Overall Payed fees) - Profit per trade (Overall profit. This can be used to easily calculate your personal capital taxes) - Profit can be calculated in EUR or USD. (Data from European Central Bank) - Amount of your Cryptocurrencies - Display the different BUY-INs by amount and date. So you can control the 12 month holding period.
Supported Exchanges: Binance, Bitfinex, Bittrex, Kraken, Mercatox, Poloniex, Costum*
*A dummy file is included that can be used to easily add trades of other exchanges. If you give me a csv-file export from other exchanges (you can modify the digits for privacy) I will add them.

4 Sub-$10 Million Market Cap Coins Worth Keeping An Eye On

1. Spectrecoin ($XSPEC) – $8.6 Million

What is Spectrecoin?

Utilizing a “range of proven cryptographic techniques” to achieve anonymous, untraceable, and un-linkable transactions, Spectrecoin is a secure Proof-of-Stake cryptocurrency enabling rapid P2P transactions and network privacy. Specifically, Spectrecoin is pulling out all the stops in order to protect user identity through their integration of:
At its core, Spectre’s dual coin system sanctions four fundamental types of privacy and anonymity transactions, XSPEC > XSPEC, XSPEC > SPECTRE, SPECTRE > SPECTRE, and SPECTRE > XSPEC, providing a plethora of transaction options for every type of user.
And finally, if you’re looking for the TLDR (too long, didn’t read), Spectrecoin notes the best way to understand SPECTRE is to think of Bitcoin + Proof-of-Stake.v3 + anonymous transactions (similar to Monero) + Tor (for IP obfuscation).

Why You Should Keep an Eye On XSPEC

Unlike several other privacy coins which merely provide a Tor proxy—availing users to potential malicious exit nodes—Spectrecoin is fully integrated with Tor, a reliable and tested network providing one of the largest pools of IP addresses for confidentiality and untraceability.
Coupled with staking, set at a 5% minimum per year, Spectrecoin offers a unique proposition (the only one in blockchain) for users looking to earn rewards while remaining anonymous by staking anonymous coins while generating more, fresh anonymous ones.
Furthermore, for those looking for affirmation of Spectrecoin’s commitment to anonymity, not even the developers know each other’s real names—something that would have made walking away from a lacklustre ICO (which only raised 16 BTC at $600/700 per BTC) all too easy.
Spectre has emphasized organic growth without an excessive and aggressive marketing push, opting instead for a working product and timely improvements to meet the ever-changing privacy arms race. And, with their funding gap set around £19,000, users can take solace in knowing the project isn’t an outright cash grab asking for millions to further tenuous goodwill—like far too many projects in the cryptosphere.
At time of writing, XSPEC is listed on CoinMarketcap at US$0.41 or 5,970 Satoshis.
Finally, if you’re wondering how Spectrecoin stacks up to other privacy coins, such as Monero, PIVX, and Zcash, check out this comparison chart.

2. FundRequest ($FND) – $1 Million

What is FundRequest?

In an age where open source software is an integral component for institutional, government, and nonprofit function and growth, there unfortunately remains a hindering factor—a cohesive, transparent, and styled request and transaction flow.
Cue FundRequest, a decentralized marketplace for open source collaboration and catalyst for global open source sharing and circulation, empowering organizations, government, and other entities to:
Need to brush up on what exactly ‘open source’ means? The Open Source Initiative describes the concept of ‘open source’ as a tool which “enables a development method for software that harnesses the power of distributed peer review and transparency of process.”
For example, a requesting organization (referred to as the funder) will allot set funds—stored in a smart contract (i.e., escrow)—in order to tackle an open source issue, which is then picked up and solved by a developer (the solver). In order to eliminate malicious behavior, FundRequest requires solvers to “have skin in the game,” by staking proportional valued funds, all released and claimed once the issue is solved.
Simply put, FundRequest is the go-to facilitating and incentivization platform (similar to Airbnb and Uber) for funding, claiming, and rewarding open source commits and contributions, leading to an enriched and more collaborative open source ecosystem.

Why You Should Keep an Eye On FND

With an estimated US$60 billion-plus in savings per year for organizations and institutions, thanks to open-source software and technology adoption, FundRequest is set to act as the glue which connects all dispersed and integral parts and actors. Traditional software, prohibitive costs, and predatory vendor practices are proving not to be conducive towards maximal technological growth and development, as most people and organizations just simply can’t afford or maintain it.
Plus, with a clear push by both private and public sectors to leverage community-based software for development and distribution over the last decade, it’s expanding at rapid pace. In 2018, it’s approximated over 50% of European and North American companies utilize open source software for “crucial applications,” along with over 50% of American government organizations.
This is no small industry.
GitHub alone boasts over 24 million users (more than 8 times their user base five years ago), and it’s estimated that in the EU and United States combined, there’s over 160 million persons working as freelancers and independent contractors in what’s known as the “gig economy.” And that’s just the tip of the iceberg, with over 60% of online gig economy workers accounted for in Asia.
As of August 1st, FND’s price sits at right around US$0.03 or 472 Satoshis.
Finally, for open source projects and ERC-20 token projects looking to increase development capacity, consider checking out FundRequest for potential partnerships. Already in their short tenure, FundRequest has partnered with:

3. COSS ($COSS) – $7.7 Million

What is COSS?

Redefining convenience, simplicity, and compatibility, and short for the “Crypto One-Stop Solution’ exchange and platform, COSS is the native token and liquidity attraction tool of the Singapore-based exchange, boasting some of the most popular altcoins on the market while enabling users to receive weekly payouts in “dust” for all traded tokens.
Specifically, COSS is looking to provide more than just a simple, fast, and secure cryptocurrency trading exchange—they’re building a borderless, digital economical system to bring cryptocurrencies to the masses via:
Ultimately, COSS is looking to shake up the cryptocurrency exchange ecosystem through improved user experience, heightened product and feature functions, and a comprehensive foundation for employers, startups, companies, and traders to build towards a more accessible and mainstream cooperative blockchain community.

Why You Should Keep an Eye on COSS

With the rapid and gargantuan successes enjoyed by both Kucoin and Binance in 2018, crypto exchanges employing user-friendly token incentivization models are becoming a go-to for users looking to generate passive income while diversifying their crypto portfolio.
However, unlike other cryptocurrency exchanges which have lowered their daily fee splits to nominal amounts, COSS has stayed true towards user rewards, keeping their daily percentage at 50%—paying out the respective dividends via a decentralized autonomous organization, ultimately guaranteeing an immutable percentage.
In order to stay competitive in the present-day blockchain ecosystem, COSS’s whitepaper notes a minimum of 3-5 new features implemented per quarter. In the past several months, below are just several of their most notable achievements:
And, if you’re looking to know what COSS’s endgame here is, their goal is to shift completely towards a decentralized autonomous organization (DAO) in the future, where governance and decision making is outlined in code and run by a peer-to-peer network.
Currently, COSS’s price is listed at US$0.06 or 935 Satoshis on Coinmarketcap.
Finally, if you’re curious about COSS’s fee sharing, check out the COSS fee share calculator, which provides an accurate picture of your monthly exchange fee earnings relative to the amount of COSS owned. One Reddit user recently posted, and provided a screenshot, showing the COSS annual dividends to be at nearly 10% per year.

4. Lamden ($TAU) – $6.9 Million

What is Lamden?

Named after the Sherpa language word meaning “to guide,” Lamden is staying true to its name by easing the creation and deployment of dapps and custom blockchains.
At its core, Lamden is providing a suite of developer tools mimicking “modern development processes in such tech stacks as Node.js or Python.” Simply put, Lamden is supplying the building blocks for experienced and amateur blockchain developers alike, enabling organizations and enterprise to skirt the energy and time costs of hiring and training expensive blockchain developers—ultimately speeding up efficiency and reducing overhead costs.
Lamden is broken up into three fundamental sections, which all are in furtherance of project depth and the deployment of hyperfast blockchains for developers to not only experiment with, but test and deploy across other blockchain systems and platforms:
Furthermore, Lamden supports the Ethereum network and Bitcoin-based blockchains at present, and boasts zero transaction fees and free chain-to-chain payments in exchange for chain allocation a specific amount of bandwidth for confirming payment channel transactions—meaning that its users are able to transact for free as a result of corporate entities bearing the network load and processing.

Why You Should Keep an Eye On TAU

Having released their ‘Cilantro’ testnet alpha in February 2018, Lamden has since hit the ground running, rolling out their first version of Clove soon after and tackling the necessary tune-ups and improvements in preparation of their mainnet launch in Q4 2018. Lamden’s mainnet is set to utilize a unique combination of Delegated Proof-of-Stake (DPoS) and the BFT Protocol, and will scale to process nearly 10,000 transactions per second.
Moreover, in April 2018, Lamden announced the creation of LamDEX, their own decentralized cryptocurrency exchange and platform, where users will be able to stake their TAU—the native token of the Lamden platform—to act as a market maker, allowing for a cohesive back and forth across the TAU pair at prices faintly above and below market cost, ultimately generating rewards.
With a rather daunting and tedious task ahead for anyone looking to utilize and incorporate existing smart contracts—which involves the manual searching for such on GitHub (a general repository website)—Lamden is truly adding value to blockchain and application development through their smart contract repository. Unlike GitHub, Lamden supports dependencies, versioning, and security, all essential elements for a quality package manager.
Doing so adds not only convenience, but practicality to smart contract packages and implementation, and stands to save enterprise and organizations both exorbitant developer costs and time.
If you’d like to learn more about Lamden’s developer tool suite, check out this complete overview from their blog.
At the time of writing, Lamden’s price according to Coinmarketcap is US$0.04 or 699 Satoshis.
To get a better picture of Lamden and their blockchain development tools ecosystem, check out this explanatory YouTube video from their channel.
Final Thoughts
Risk is inevitable when investing in crypto and blockchain projects. However, as long as you are cognizantly defining parameters for absorbing such risk, then diversifying your portfolio with smaller capped projects can be an effective way to realize value.
Whether you’re looking for a user-friendly exchange to purchase crypto directly with fiat from (and earn dividends for loyalty) or wanting to execute anonymous and secure transactions with a P2P coin, the aforementioned projects are all bringing value to the crypto sphere through their overhaul of ineffective traditional mechanisms and institutions.
Make sure to stay calm and collected during this bear market, associate yourself with quality projects that you think are bringing actual value to severely flawed industries, and remember, having a little gamble in you never hurts (as long as it’s properly accounted for).
