Binance Set To Launch A Crypto Mining Pool

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.

Interview With Eddie Jiang: How CoinEx Is Adapting To The Exchange Space And Growing

Interview With Eddie Jiang: How CoinEx Is Adapting To The Exchange Space And Growing
Written by chaintalk.tv
https://preview.redd.it/v238540taz751.jpg?width=1280&format=pjpg&auto=webp&s=2a852e171a74e49da802d7c12fadba452cf4cf43
We recently had the opportunity to interview the VP of ViaBTC Group, Eddie Jiang. ViaBTC Group owns popular crypto exchange CoinEx and ViaBTC Pool. In this interview Eddie discusses being the first exchange to use BCH as the base currency, ViaBTC Pool and integrating with CoinEx, new features and ambassador program, and competing with other exchanges like Binance and Huobi. Please enjoy the interview below.
How come you decided to open up CoinEx to other cryptos other than just BCH?
Eddie Jiang: CoinEx is the world’s first exchange to implement Bitcoin Cash as a base currency. At that time, it was evident that there was a demand for BCH trading markets, and we are the first to explore this opportunity. It also shows our determination to support the BCH’s development.
As CoinEx is developing, our goal becomes bigger and we are aiming at the global market. We need to constantly improve our product diversification to meet the different needs of more users, so we open up to other cryptos. In the past six months, we have listed more than 50 new tokens. Up to now, we have listed 129 cryptos and 313 markets. Besides, in addition to spot trading, CoinEx also supports perpetual contract and other derivatives trading.
How does CoinEx integrate with the ViaBTC Pool?
Eddie Jiang: ViaBTC Group announced a strategic upgrade, which included a new organizational structure, product innovations and service improvements, on 30 May.
As part of the change, the Group has established three dedicated business units (BU): the financial services BU, consisting of ViaBTC mining pool and CoinEx exchange; the infrastructure services BU, including ViaWallet and Blockchain Explorer; and the ecological development BU, focusing on the research and development of public chain technology and the construction of the ecology.
After halving, the combination of mining and finance will become closer and closer. Investing in mining machines is like buying a Bitcoin option. Miners need more flexible financial products to maintain and increase the value of assets, or hedging services. Based on this judgment, the operations of ViaBTC mining pool and CoinEx exchange will be integrated in the future to realize the financial empowerment of the mining pool to meet the diverse financial needs of miners.
Features of this integrated product upgrade can be summarized as: “ The mining pool is the wallet, and the wallet is the transaction.” ViaBTC is the world first mining pool that has a wallet embedded in the mining pool account. Users do not need to transfer the mined coins, and can realize the function of coin exchange within the wallet. For example, they can directly convert the mined coins into USDT to pay electricity bill. What’s more, users can store, deposit and withdraw their revenue, and transfer assets to CoinEx at any time without charge, as well as complete other operations on the exchange, such as purchasing wealth management products for asset preservation and appreciation. In addition, we also provide hedging services. All of the above functions can be completed in one stop in the mining pool, without the need to transfer assets between different platforms.
The exchange empowers the mining pool, and the mining pool will further bring more traffic and resources to the exchange. The two complement each other and development coordinately.
CoinEx has recently added many new features. Can you talk about what new updates were made to the platform and why you made them?
Eddie Jiang: We have always attached great importance to the development of overseas markets since our establishment, and one of our major goals this year is to cover at least 10 different languages speaking markets.
To realize this and to meet the needs of more users worldwide, CoinEx has been continuously optimizing and upgrading its operating strategies, products and services. Our product diversifications are constantly improving. As I said before, we have launched leverage trading, perpetual contract trading, and wealth management products in addition to just spot trading. However, we don’t ignore the importance of spot trading. More mainstream, popular, and high-quality tokens have been listed, and up to now, there are 129 tokens and 313 trading pairs on CoinEx.
During the epidemic, we have never slowed down our development. Lacking of the OTC service has always been a shortage for CoinEx. In March, we partner with Simplex to integrate the first fiat onramp to our platform. People now can buy crypto with their credit cards, which lowers the threshold for more people to enter the crypto world. Moreover, we announced global strategic partnership with Matrixport to provide people with large amount of fiat to crypto needs the OTC service. These newly launched services also help to attract more users.
At the same time, CoinEx has been launched in Arabic, Italian, English, Japanese, Russian, Korean and other 16 languages. Earlier we also carried out product upgrades, making the UI and function sections clearer.
In terms of operations, we launched an upgraded CoinEx Ambassador program in March. To best utilize each ambassador’s personal strengths, there are four categories of CoinEx Ambassador with different responsibilities, namely Referral Ambassador, Marketing Ambassador, Operation Ambassador, and Business Ambassador, which will expand our brand’s exposure and help CoinEx grow into a more international exchange platform.
From March until now CoinEx has seen a 100% increase in user registrations. Why is that and are you able to see where they are coming from?
Eddie Jiang: Because of the efforts mentioned above, in 2020, we’ve seen an exponential increase in activity in just the past few months alone. In this year alone, CoinEx’s daily registered users increased by 100%. These new users mainly come from markets such as the Middle East, Asia Pacific, and more.
Interestingly, we saw an uptick in traffic from the Middle East in March. User growth in Southeast Asia also picked up significantly, newly registered users increased by 133.6% in April.
With Binance, BitMex, Huobi, Bybit, and Deribit, controlling most of the crypto futures and options markets, where do you see CoinEx fitting in? How do you plan to capture market share from these large exchanges?
Eddie Jiang: We won’t compete with others. We focus on ourselves to improve products and our goal is to be better than yesterday.
Our pace is solid and steady, instead of focusing on temporary heat and flow. We have always attached great importance of spot trading, and we are committed to be responsible for users’ investment. We have set up CoinEx Institution, which is dedicated on project research. A listing committee consist of core team members review and vote on projects recommended by the CoinEx Institution. In this way, fraud projects are avoided as much as possible.
Besides, we will focus on niche areas with great potential. For example, Southeast Asia and the Middle East. CoinEx can serve users in those countries well by providing a platform with rich cryptos to trade, and will pay more efforts on refined operations in different countries.
Moreover, CoinEx has a very complete ecosystem. Financial services, infrastructure, and ecological development, the three business units complement each other. The infrastructure BU is our cornerstone and is positioned as a defensive product; the financial service BU is a cash cow and is positioned as an aggressive product; the ecological development BU focuses on the public chain ecology and is the future infrastructure.
What is the geographical breakdown of the CoinEx userbase?
Eddie Jiang: The current proportion of CoinEx’s overseas users has reached 80% of the total registered users, and mainly in Australia, Southeast Asia, North America, Middle East and South Korea.
Do you have plans to focus on any certain jurisdictions? How will you do that?
Eddie Jiang: When we evaluate regions, two things matter: policy and potential.
Whether an exchange’s business expansion in a region is smooth or not largely depends on the region’s policies. If the region is not very friendly towards cryptocurrency or has repeated attitudes, there will be more difficulties and the cost will be much higher.
For a region’s development potential, we need to think about the demand and market development status. South Korea, Southeast Asia, the Middle East and other regions are all areas with good potential for cryptocurrency development. Compared with Europe and America, policy risks in these countries are lower, and the supervision mechanism is relatively complete. The public has a high degree of awareness of cryptocurrencies. Besides, some regions or countries have inflation problems due to political and economic reasons.
CoinEx will continue to focus on the Middle East and South Asia, which are relatively niche. India has just lifted ban on cryptocurrency trading this year, and there are many cryptocurrency investors in Indian. CoinEx can serve them well by providing a platform with rich cryptos to trade. More people in the Middle East are interested cryptos, especially in countries that are subject to economic sanctions or high inflation. For those people, cryptocurrencies are one of the best choices for asset preservation.
Since the CoinEx Ambassador program launched in March, it has been almost three months. We are conducting the second round of ambassador recruitment. This time, we will use the power of ambassadors to expand our recruitment coverage and strive to attract more crypto enthusiasts from all over the world to grow together with CoinEx. Moreover, we will launch the National Expansion plan and leverage on the CoinEx and ViaBTC mining pool resources, to further explore the Russian market. At the market level, we will make more PR efforts in local markets, and start refined operations.
What is CoinEx Chain and CoinEx DEX?
Eddie Jiang: CoinEx Chain is a public chain built on the Tendermint consensus protocol and the Cosmos SDK. It consists of three dedicated public chains parallel to each other. Among these three chains, CoinEx DEX meets the most basic needs of DeFi for token issuance, transfer, and transactions. The Smart Chain is designed to meet the needs of complex financial scenarios and delivers programmable cash. The Privacy Chain facilitates privacy and security.
On November 11, 2019, we took the lead in launching the Mainnet of CoinEx DEX. CoinEx DEX is the world’s first public chain dedicated to decentralized transactions. Users can easily manage their digital assets on it.
CoinEx DEX can fully satisfy the following conditions: users have private keys at their own disposal; transfers and transactions are all completed on-chain, which is 200% transparent and checkable; the issuance, transfer, and transaction of tokens do not require review or permission; the community governance and operation is decentralized, similar to EOS, and validators are introduced to the community ecosystem construction and governance. There are currently 41 validators.
It also has extreme performance. TPS reaches as high as 10,000 and transactions are confirmed within seconds. The transaction fee, 0.0001 US dollars for each transaction, is negligible.
Third, it’s simple and easy to use. The new operation interface design helps beginners get started quickly; with the one-click token issuing module, users only need to fill in a few items to issue tokens; the built-in automated market-making module guarantees liquidity.
How will CoinEx DEX improve the decentralized exchange space that has been unable to gain much adoption?
Eddie Jiang: There are many challenges and difficulties facing centralized exchanges. The first difficulty is security. Security is a huge concern for CEXs. Over the last 10 years, hackers have stolen more than $1.5 billion from centralized exchanges. In fact, research groups estimate that hackers stole somewhere between $950 Million and $1 Billion from centralized exchanges in 2018 alone. There were also incidents of coin thefts in other exchanges in 2019. Many exchanges, such as Mt. Gox, Youbit, were forced to file for bankruptcy and shut down as a result of hacks.
The second is high management costs. Centralized exchanges need to list a large number of cryptocurrencies and each of them have different trading pairs. That entails huge efforts in development and maintenance and, thus, high management costs.
The last is global policies. Cryptocurrency is faced with different regulatory policies in different countries. Every time a centralized exchange enters a country, it needs to adapt itself to local regulatory policies for compliance. This is a holdback for the exchange’s rapid market expansion globally. Such adaptation will also bring a huge learning cost for the exchange team.
Obviously, these problems can be well solved by DEX. CoinEx DEX is a true DEX with full open source and full community governance, as well as without depending on official nodes, websites, wallets, etc. On DEX, users are able to in charge of their own private keys and assets all by themselves. Their assets are more safe and secure. Transfers and transactions are all completed on-chain, which is 200% transparent and checkable; and the issuance, transfer, and transaction of tokens do not require review or permission. What’s more, CoinEx DEX provides a great and convenient user experience.
How will CoinEx Chain and DEX help the crypto industry as a whole?
Eddie Jiang: The public chain is the cornerstone of the blockchain industry. CoinEx Chain has the parallelism of multiple dedicated public chains, each of which performs its own functions, by cross-chaining for both high performance and flexibility.
CoinEx Chain is committed to building the next generation of blockchain financial infrastructure. It is a more complete ecosystem built around the DEX public chain. The DEX public chain is a dedicated public chain developed specifically for token issuance and trading and the biggest improvement on trading speed, so it only supports the necessary functions, not smart contracts.
But smart contracts are the foundation for building more complex financial applications. Outside the DEX public chain, CoinEx Chain also includes a Smart Chain that supports smart contracts.
Moreover, as privacy issues on the current blockchain have been criticized, it is one of the core tasks of CoinEx Chain to safeguard users’ privacy. Similar to the Smart Chain, the Privacy Chain specifically supports transaction privacy protection. With cross-chain circulation, it can improve the privacy characteristic of the entire CoinEx Chain ecosystem.
Nowadays, 1.7 million people in the world have no bank accounts; however, among them, two thirds are smartphone users with huge demands for financial services. The public chain will empower DeFi applications’ development and popularization, not only help more companies to seize the huge market opportunity, but also to bring lasting transformations and improvements in people’s lives.
With so many crypto exchanges, what is the future outlook of CoinEx when it comes to the crypto exchange space?
Eddie Jiang: It has been nearly 3 years since CoinEx has been launched, but it’s quite young for an entrepreneurial team. We have seen too many projects’ failures due to governance issues. CoinEx has a very elite team with high technical and management capabilities. In terms of business, CoinEx has gradually developed with diversified business and a complete ecosystem. It’s clear that the market will still grow very fast in the future, and the market size is still very large. We will continue to improve our products, put more efforts in marketing and operations, as well as look for more high-quality projects, to increase the number of users and transactions on the platform. Lay a solid foundation, and I’m sure the time will come for us to shine.
What updates is the CoinEx team most excited for?
Eddie Jiang: We are very excited about the National Expansion Plan which will be launched later this year. It is an important part in CoinEx’s globalization strategy. We will actively explore some new markets while consolidate the original ones. CoinEx will set aside 10 million US dollars to set up a “Pioneer Fund” to support this plan. This fund will be used to support local cryptocurrency projects and promote the development of the local cryptocurrency communities through investment or cooperation. Our goal this year is to invest in projects and communities that are conducive to expanding the CoinEx ecosystem in countries with high development potential.

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.

Information and FAQ

Hi, for everyone looking for help and support for IOTA you have come to the right place. Please read this information, the FAQ and the side bar before asking for help.

Information

IOTA

IOTA is an open-source distributed ledger protocol launched in 2015 that goes 'beyond blockchain' through its core invention of the blockless ‘Tangle’. The IOTA Tangle is a quantum-resistant Directed Acyclic Graph (DAG), whose digital currency 'iota' has a fixed money supply with zero inflationary cost.
IOTA uniquely offers zero-fee transactions & no fixed limit on how many transactions can be confirmed per second. Scaling limitations have been removed, since throughput grows in conjunction with activity; the more activity, the more transactions can be processed & the faster the network. Further, unlike blockchain architecture, IOTA has no separation between users and validators (miners / stakers); rather, validation is an intrinsic property of using the ledger, thus avoiding centralization.
IOTA is focused on being useful for the emerging machine-to-machine (m2m) economy of the Internet-of-Things (IoT), data integrity, micro-/nano- payments, and other applications where a scalable decentralized system is warranted.
More information can be found here.

Non reusable addresses

Contrary to traditional blockchain based systems such as Bitcoin, where your wallet addresses can be reused, IOTA's addresses should only be used once (for outgoing transfers). That means there is no limit to the number of transactions an address can receive, but as soon as you've used funds from that address to make a transaction, this address should not be used anymore.
The reason for this is, by making an outgoing transaction a part of the private key of that specific address is revealed, and it opens the possibility that someone may brute force the full private key to gain access to all funds on that address. The more outgoing transactions you make from the same address, the easier it will be to brute force the private key.
It should be noted that having access to the private key of an address will not reveal your seed or the private key of the other addresses within your seed / "account".
This piggy bank diagram can help visualize non reusable addresses. imgur link

Address Index

When a new address is generated it is calculated from the combination of a seed + Address Index, where the Address Index can be any positive Integer (including "0"). The wallet usually starts from Address Index 0, but it will skip any Address Index where it sees that the corresponding address has already been attached to the tangle.

Private Keys

Private keys are derived from a seeds key index. From that private key you then generate an address. The key index starting at 0, can be incremented to get a new private key, and thus address.
It is important to keep in mind that all security-sensitive functions are implemented client side. What this means is that you can generate private keys and addresses securely in the browser, or on an offline computer. All libraries provide this functionality.
IOTA uses winternitz one-time signatures, as such you should ensure that you know which private key (and which address) has already been used in order to not reuse it. Subsequently reusing private keys can lead to the loss of funds (an attacker is able to forge the signature after continuous reuse).
Exchanges are advised to store seeds, not private keys.

Double spending

Sending a transaction will move your entire balance to a completely new address, if you have more than one pending transaction only one can eventually be confirmed and the resulting balance is sent to your next wallet address. This means that the other pending transactions are now sent from an address that has a balance of 0 IOTA, and thus none of these pending transactions can ever be confirmed.

Transaction Process

As previously mentioned, in IOTA there are no miners. As such the process of making a transaction is different from any Blockchain out there today. The process in IOTA looks as follows:
  • Signing: You sign the transaction inputs with your private keys. This can be done offline.
  • Tip Selection: MCMC is used to randomly select two tips, which will be referenced by your transaction (branchTransaction and trunkTransaction)
  • Proof of Work: In order to have your transaction accepted by the network, you need to do some Proof of Work - similar to Hashcash, not Bitcoin (spam and sybil-resistance). This usually takes a few minutes on a modern pc.
After this is completed, the trunkTransaction, branchTransaction and nonce of the transaction object should be updated. This means that you can broadcast the transaction to the network now and wait for it to be approved by someone else.

FAQ

How do I to buy IOTA?

Currently not all exchanges support IOTA and those that do may not support the option to buy with fiat currencies.
One way to buy IOTA is to buy with bitcoin (BTC) or Ether (ETH), first you will need to deposit BTC/ETH onto an exchange wallet and you can the exchange them for IOTA.
You can buy BTC or ETH through coinbase. And exchange those for IOTA on Binance or Bitfinex (other exchanges do exist, some linked in the side bar).
A detailed guide to buying can be found here.

What is MIOTA?

MIOTA is a unit of IOTA, 1 Mega IOTA or 1 Mi. It is equivalent to 1,000,000 IOTA and is the unit which is currently exchanged.
We can use the metric prefixes when describing IOTA e.g 2,500,000,000 i is equivalent to 2.5 Gi.
Note: some exchanges will display IOTA when they mean MIOTA.

Can I mine IOTA?

No you can not mine IOTA, all the supply of IOTA exist now and no more can be made.
If you want to send IOTA, your 'fee' is you have to verify 2 other transactions, thereby acting like a minenode.

Where should I store IOTA?

It is not recommended to store large amounts of IOTA on the exchange as you will not have access to the private keys of the addresses generated.
However many people have faced problems with the current GUI Wallet and therefore group consensus at the moment is to store your IOTA on the exchange, until the release of the UCL Wallet, or the Paper Wallet.

What is the GUI wallet?

What is the UCL Wallet?

What is a seed?

A seed is a unique identifier that can be described as a combined username and password that grants you access to your wallet.
Your seed is used to generate the addresses linked to your account and so this should be kept private and not shared with anyone. If anyone obtains your seed, they can login and access your IOTA.

How do I generate a seed?

You must generate a random 81 character seed using only A-Z and the number 9.
It is recommended to use offline methods to generate a seed, and not recommended to use any non community verified techniques. To generate a seed you could:

On a Linux Terminal use the following command:

 cat /dev/urandom |tr -dc A-Z9|head -c${1:-81} 

On a Mac Terminal use the following command:

 cat /dev/urandom |LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1 

With KeePass on PC

A helpful guide for generating a secure seed on KeePass can be found here.

With a dice

Dice roll template

Is my seed secure?

  1. All seeds should be 81 characters in random order composed of A-Z and 9.
  2. Do not give your seed to anyone, and don’t keep it saved in a plain text document.
  3. Don’t input your seed into any websites that you don’t trust.
Is this safe? Can’t anyone guess my seed?
What are the odds of someone guessing your seed?
  • IOTA seed = 81 characters long, and you can use A-Z, 9
  • Giving 2781 = 8.7x10115 possible combinations for IOTA seeds
  • Now let's say you have a "super computer" letting you generate and read every address associated with 1 trillion different seeds per second.
  • 8.7x10115 seeds / 1x1012 generated per second = 8.7x10103 seconds = 2.8x1096 years to process all IOTA seeds.

Why does balance appear to be 0 after a snapshot?

When a snapshot happens, all transactions are being deleted from the Tangle, leaving only the record of how many IOTA are owned by each address. However, the next time the wallet scans the Tangle to look for used addresses, the transactions will be gone because of the snapshot and the wallet will not know anymore that an address belongs to it. This is the reason for the need to regenerate addresses, so that the wallet can check the balance of each address. The more transactions were made before a snapshot, the further away the balance moves from address index 0 and the more addresses have to be (re-) generated after the snapshot.

Why is my transaction pending?

IOTA's current Tangle implementation (IOTA is in constant development, so this may change in the future) has a confirmation rate that is ~66% at first attempt.
So, if a transaction does not confirm within 1 hour, it is necessary to "reattach" (also known as "replay") the transaction one time. Doing so one time increases probability of confirmation from ~66% to ~89%.
Repeating the process a second time increases the probability from ~89% to ~99.9%.

What does attach to the tangle mean?

The process of making an transaction can be divided into two main steps:
  1. The local signing of a transaction, for which your seed is required.
  2. Taking the prepared transaction data, choosing two transactions from the tangle and doing the POW. This step is also called “attaching”.
The following analogy makes it easier to understand:
Step one is like writing a letter. You take a piece of paper, write some information on it, sign it at the bottom with your signature to authenticate that it was indeed you who wrote it, put it in an envelope and then write the recipient's address on it.
Step two: In order to attach our “letter” (transaction), we go to the tangle, pick randomly two of the newest “letters” and tie a connection between our “letter” and each of the “letters” we choose to reference.
The “Attach address” function in the wallet is actually doing nothing else than making an 0 value transaction to the address that is being attached.

How do I reattach a transaction.

Reattaching a transaction is different depending on where you send your transaction from. To reattach using the GUI Desktop wallet follow these steps:
  1. Click 'History'.
  2. Click 'Show Bundle' on the 'pending' transaction.
  3. Click 'Reattach'.
  4. Click 'Rebroadcast'. (optional, usually not required)
  5. Wait 1 Hour.
  6. If still 'pending', repeat steps 1-5 once more.

What happens to pending transactions after a snapshot?

How do I recover from a long term pending transaction?

How can I support IOTA?

You can support the IOTA network by setting up a Full Node, this will help secure the network by validating transactions broadcast by other nodes.
Running a full node also means you don't have to trust a 3rd party in showing you the correct balance and transaction history of your wallet.
By running a full node you get to take advantage of new features that might not be installed on 3rd party nodes.

How to set up a full node?

To set up a full node you will need to follow these steps:
  1. Download the full node software: either GUI, or headless CLI for lower system requirements and better performance.
  2. Get a static IP for your node.
  3. Join the network by adding 7-9 neighbours.
  4. Keep your full node up and running as much as possible.
A detailed user guide on how to set up a VTS IOTA Full Node from scratch can be found here.

How do I get a static IP?

To learn how to setup a hostname (~static IP) so you can use the newest IOTA versions that have no automated peer discovery please follow this guide.

How do I find a neighbour?

Are you a single IOTA full node looking for a partner? You can look for partners in these place:

Substratum leads Round 2 of Monthly Community Voting Round - AMA Transcript Inside!

Hey guys, If you haven’t noticed on Binance’s monthly community voting round – it has been a tight battle but Substratum has been taking the lead.
I wanted to explain why Substratum has seemingly come out of no-where but has garnered some attention. Substratum is creating a solution to a very big obstacle in the world web. The below has been taken from Justin Tabb aka the Founder of Substratum and summarises what the purpose of the network is.
I hope you guys can support their vision by voting for Substratum (SUB) on the https://www.binance.com/vote.html.
The Substratum Network will bring the decentralized web worldwide without the need of special software for the average internet user. We will be able to serve Substratum Requests directly to the default browser (Safari, Firefox, Chrome, Internet Explorer) without any special software installed on the average consuming users computer.
How Substratum Works
Ease of Use: currently nearly everything that has to do with crypto or the blockchain is very difficult to use and requires technical knowledge. Through our 10+ years of experience working with companies like Apple we understand the importance of a good user experience.
• The average internet user requires NO special software to use the Substratum Network. The default browser will service all requests for average users so they do not need to do ANYTHING different. Users who wish to service requests and receive SUB coins in return will have a point and click user interface that any user can setup. No technical knowledge required. SubstratumPay will be seamlessly integrated and geared towards high conversions of low technical expertise users. • Serving Up of Decentralized Content: Substratum provides a method for serving Decentralized Content (including Web Sites, Data, and Applications) through a Mac, Windows, and Linux application/service that is easy to install and run (requires no technical expertise) and serves up decentralized content using the toolkit that we have developed. This is a point and click process and requires zero technical knowledge. All the user has to do is install the application, click through a few settings and they are up and running and making Substratum Coin. Incentivizing Users to Serve the Content: in order to incentivize users to run the Substratum Network client on their machine we will be providing Substratum Coin to them for doing so. The coin is issued to the serving machine through a micro-transaction from the hosting site to the serving computer. By breaking fees down to a micro-transaction level this will greatly reduce the overall cost to companies and entities that want to host sites and applications on the internet solving yet another problem with the web as it stands today.
Privacy / Security / Encryption: by allowing millions of Substratum Network users to serve content the biggest concern becomes privacy and security. Substratum solves these issues through advanced cryptography algorithms rooted in Artificial Intelligence that ensures all data remains secure. Following the lead of BitCoin this is the strength of cryptocurrency and the crypto movement. Storage and Serving of Content: in order to serve millions of sites, databases, and applications the Substratum Network employs custom developed advanced compression algorithms and machine learning to geolocate the right Substratum Network machine to serve up the content to the appropriate user based on geolocation, this will ensure the fastest load time with the lowest amount of latency and strain on the Substratum Network and both the serving and receiving machine. DNS (Domain Name System): DNS or the Domain Name System is the system that currently tells your browser where to go when you type in a domain name. For instance when you go to Chrome and type in apple.com a DNS lookup is performed to check where to send that request, the DNS system comes back with an IP address and your request is routed there. In the first version of SubstratumDNS will be a complex, AI enabled DNS server that will receive DNS requests along with the geolocation of the requestor and find based off of that information the closest available SubstratumNode that is able to fulfill the request. Development Tools for the Decentralized Web: the Substratum Network will provide an API and SDK for developing tools on the Substratum Platform. This will bring in strong developer support and will accelerate the growth of the decentralized web on the Substratum Network. Net Neutrality: with the Substratum Network ALL web-sites and applications will have EQUAL ability to be broadcast in an equal and fair manner.
International Digital Barriers: currently countries like China have strict regulations on what their 1.379 billion citizens are able to interact with on the internet. Substratum will break down these barriers through a network of decentralized computers running the Substratum Network Software. Where other solutions that are currently used by residents in these countries require special software to be installed, like TOR, Substratum will take a reverse approach and require no special software for the average user.
High Hosting Costs: currently businesses must pay high hosting fees to get their web-sites on the internet. Amazon Web Services launched a 3.5BIL USD per year business by attempting to solve this problem. They allow you to pay for how many minutes you run a web / database server. Substratum completely solves this problem through the power of cryptocurrency by only charging for each request that is processed. You can check out the website here: • Substratum.net o And the whitepaper is available in multiple languages inclusive of Mandarin.
Furthermore, Substratum and the founders are very active in the slack – which they have recently hosted an AMA (ask me anything); I took the liberty of getting this information and if you are interested about the project to read more into it. Obviously they can’t reveal the inner workings of their product due to product sensitivity and being ahead of their competition but they are always up to date with the community through several videos on Youtube (https://www.youtube.com/channel/UCxUJoTH0XLERKl55zGnFI6g) and announcements through their social media. I recommend you follow them.
Q: Any major talks with exchanges yet? A: We just announced that we are launching on our FIRST official exchange of COSS.IO on 9/30 trading against BTC and ETH. More to follow.
Q: Will I be able to run a supernode? A: From the beginning NO. Supernodes will only be for Substratum; however, they will run the SAME software that are used to run a NODE. In time we will develop a requirement list to run a supernode. If you qualify you can then run a SuperNode and receive a premium payout
Q: Is it possible to show a few examples of SUB payouts you get from running a node, and the tell us the ratios that affect the amount/way to calculate it somehow? (SUB owned, for how long you've been running a node etc..) Or is that still in testing? What's the difference in node rewards from someone who has 0 SUB's as opposed to someone who has X amount of SUB's? A: So the calculations for this are in process; however, you can watch our video "How Substrate Per Request Is Calculated" on our YouTube channel for an idea of what variables go into each calculation
Q: How do we prevent DDoS? A: The first step is not talking about how we prevent DDoS or any other hack. We call that security through obscurity. :slightly_smiling_face: Secondly, one of the primary ways to prevent a DDoS attack is decentralization. Well that's perfect. Lastly, there are other techniques, like black-holing and basically shutting a node down. The great news is that we will be decentralized so we are only talking about a node or specific IP Address that will not disrupt the network. :thumbsup:
Q: Say i got a website i want to publish on Substratum, how does this process go? A: Just a shout out if you ask for a lot of detail regarding technology stack and how exactly something will work we are most likely going to give you general answers. This is not to skirt the question. We want to be 10 steps ahead of anyone with nefarious plans before we get launched. You will be seeing more on this very soon. You should be seeing a video drop on this in the next week or two. The goal is to make this easy to use and powerful, plus empower others to use the tools. We're looking at things to different ways one is towards the average user who just want something sitting on their system and doesn't need any more details and the other is a super user who wants a lot of configuration options.
Q: When more people will use Substratum and more will run nodes, the value of SUB will increase. How will it be calculated how much SUB you get as a reward for running a node as value increases? Will it be calculated by Substratum itself or will it be changed manually every so often? A: We will be calculating against the live value of Substratum
Q: Is substratum detectable, for example if it’s used in a country like china and they are caught on these sites that are blocked by government… Can it be detected? A: The goal is to make it constantly moving. We do not want it to be. fast, easy, powerful, anonymous.
Q: Will there be Master Nodes? A: We will have some services that are available that will help provision nodes into the network. We are still story mapping this flow and architecture.
Q: Could we get more information about what you require to do to be a beta tester? A: To be a beta tester you only need to add yourself to the #beta-tester channel here in Slack. You will be notified when we are ready for you to download and install and the process and requirements to continue to run the software
Q: Will you keep us informed on a at least weekly base to tell/ show us the progress made? A: Yes! We will continue to drop at least 2 professionally made update videos each week (with Jason Burns the guy who does them) and we will be doing more and more candid videos
Q: Who is the winner of 10k subs and what idea did he give? And what about 2nd place and 3rd place. A: To be announced shortly. The Substrate is reserved for the payout
Q: Can we mine Sub without the software? A: I will personally be selling pick-axes on my personal website "pixaxesforsale.biz" for a low cost of $19.99
Q: Unless they disclose intelligent life in space, people are still going to be mad at the end of this. A lot more will be happy though A: Haven't found intelligent life in space. Some would question finding it on earth.
Q: From a legal stand point How are we protected if someone is running illegal content on our Node? A: Take a look at our video of "How Substratum Secures Your Site Content". You will never hold the entire piece of data except perhaps in memory if you are the one serving the request so you could never be culpable. Amazon isn't held responsible if I host illegal content now
Q: What about content control? child porno .. and so on ... ? Is there anything to control the content or? A: Excellent question. This was a big concern for us. We do not want Substratum to become the dark web. The goal is to allow the community to self-govern, vote up and down, call out illegal activity. The utilities will allow those with bad intentions to be called out. The more we grow the better we will be about wiping out things like child porn, and just as bad human trafficking.
Q: When will the raised money going to be donated? A: We have already donated $10K out and we have a pending wire for $40K going out Monday. We are working to find the BEST places with the IMMEDIATE needs.
Q: When will the livestream of the burn be? A: Burn #1 will be a livestream of my computer screen later tonight. I will announce on twitter at least an hour ahead of time and we will record it so people can see it later
Q: What will the final circulating supply be after all three token burns? A: We are still getting a FINAL number on this, we are still doing some FINAL Bonus sends but we will have the number VERY VERY soon and we will be posting it. We will be burning 60MIL tokens tonight so that should give you some kind of an idea.
Q: can you stop slack from freezing my firefox? A: Use the downloadable app, or get better internet, or get a new computer. Sounds like a dumpster fire.
Q: Everyone brings up the obvious choice of child porno that needs to be dealt with via content control. What about grayzones such as weed-selling sites? Its illegal in some countries, some not. How will Substratum deal with these grey-zones? A: Give me liberty or give me death.
Q: Could i have an invite to beta test channel on slack? A: Yes, just let a moderator know.
Q: could i get more information on what beta testers are required to do? I will happily be one if it helps the process and I actually manage to do it. A: Join the #beta-testers channel here
Q: when will we see a new homepage? A: This is being worked on now!
Q: is there a minimum amount of SUB needed to run a node? A: NO! 0 Substrate, don't worry, you will have some soon once you turn it on
Q: What about running an "micronode" on any phone (there is a big % using phones all the time), I mean an app installed on phone to run a node and to host only small content like a photos... Did you think about of this? A: https://youtu.be/h6tZ_ZFuFmY
Q: What if my website ethically and morally right and people downvote it out of jealousy will my website be removed if there are more number of downvotes and my content is clean? A: The process is NOT that simple, we will release more details later but this is being taken into consideration. I answered in a bit more detail above as well
Q: Does the Sub team ever sleep ? A: Only when driving
Q: Can I run a node on a VPS? A: I certainly won't be telling people how or where to run the node software. Do the best you can. I actually answered the VPS question above too. We will have a command line version if that is the question. That you can run on something like Ubuntu Server if you want
Q: Can the voting system for all illegal stuff on the internet also be used in a 'bad' way on the regular websites to for example gain commercial/business advantages? A: It should not, no one will have 'master control' All control, so the market decides always.
Q: Who will profit from cryptopay? How will this bring value to SUB tokens? A: Everyone will as we gain dominance. But also, Substratum the company will take a small percentage. This will enable us to continue building awesome apps. CryptoPay will be the cornerstone of many good things to come. Think retail, goods and services.
Q: I work at a games company with 200+ high powered pcs. If I install sub nodes on every single one of them at night, will IT be able to catch and fire me A: See your HR manual, or HR supervisor for those questions.
Q: How do websites and hosters remain protected from hacking, if sites are created with innate vulnerabilities does that expose other sites hosted by the same node? A: This is a great question. Hosting Nodes will have to vet out their security. Again, being decentralized goes a long way in providing security. So does encryption. We will help hosts be the best hosts possible.
Q: Please explain the earning in SUB by running a node? A: So the SUB comes FROM the HOST (who purchases the SUB) to the NODE for the cost of the transaction. https://youtu.be/LWZ1DIGGOoQ
Q: When will the tokens be sent for the 100 Sub giveaway A: Shortly
Q: How will Substratum market themselves towards countries that needs SUB the most but are hard to reach, such as North Korea, Africa, China? A: Think spider web. The more that join, and use, the less it can be controlled.
Q: How long will this bear market last for? A: Let me put the fortune teller hat on. Crypto is a young demographic currently. It will be bear'ish until we make the technology easier and they get older.
