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:
https://github.com/dragonchain/spirit-bomb

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.

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants… Bonne découverte.
La guerre contre Bitcoin
Bitcoin est peut-être le meilleur outil de liberté économique de cette génération, et peut-être depuis plusieurs générations. Malheureusement, Bitcoin a été furieusement étouffé par une guerre civile brutale depuis environ cinq ans maintenant; menée par des ingénieurs sociaux professionnels de certaines des entreprises les plus puissantes de l'espace des médias sociaux. Leur talent dans l'art et la science de la manipulation a permis aux "Bitcoiners" de se battre largement entre eux plutôt que de chercher à créer des modèles commerciaux innovants basés sur les données qui pourraient révolutionner l'économie mondiale via Bitcoin.
À la suite de la guerre civile de Bitcoin, trois versions concurrentes de Bitcoin ont vu le jour (BTC, BCH et Bitcoin SV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes - jusqu'à un "exit scam" presque garantie, le fait de disparaitre du jour au lendemain avec tout l'argent des utilisateurs. Le principal bienfaiteur de la guerre civile Bitcoin a été Ethereum: une machine à états mondiale qui permet un déploiement facile de tokens et de contrats intelligents, mais le protocole Ethereum ne peut pas évoluer, et parmis les milliers de projets lancés, seule une poignée pourrait même être présentée comme avoir les ingrédients nécessaires pour devenir des entreprises légitimes. La plupart des autres sont des stratagèmes de Ponzi ou des émissions d'actions illégales - enrichissant les développeurs et escroquant les investisseurs amateurs.
C'est dans ce contexte que les défenseurs de BTC et de BCH, les porte-parole d'Ethereum et les altcoiners de tous bords s'alignent pour attaquer sans cesse le protocole Bitcoin préservé uniquement par le réseau BSV. Une industrie composée presque entièrement de criminels, de fraudes et d'arnaqueurs s'est unie contre BSV citant (et c'est là l'ironie) une prétendue fraude et arnaque présumée qui est l'existence même de BSV.
Nous devons nous demander pourquoi ?
Quel est le différenciateur clé de BSV?
Pourquoi tous les arnaqueurs se sont-ils unis contre lui?
Je suis fermement convaincu que pour la plupart, la motivation est la peur de la capacité de BSV à absorber l'économie mondiale et tous les autres projets «crypto» qui vont avec. Pour les autres, ou ceux qui ne comprennent pas le pouvoir du Bitcoin, ils sont entraînés dans une guerre culturelle qu'ils ne comprennent pas. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale.
Une histoire brève
Bitcoin a été lancé avec un "livre blanc" sur la liste de diffusion de cryptographie en 2008. Le pseudonyme « Satoshi Nakamoto » a déclaré une solution au problème de la double dépense. Or le problème de la double dépense de tous les précédents systèmes de paiement électronique était le seul facteur limitant l'adoption d'une monnaie électronique fonctionnelle. Il était impossible de prouver exactement qui possédait quelles unités d'argent sur leurs registres distribués, de sorte que les systèmes ne pouvaient pas faire confiance, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé « preuve de travail». Il poste la question: qui a brûlé le plus de puissance de calcul pour résoudre des énigmes arbitraires afin de rendre compte de l'état du registre d'une manière qui coûte de l'argent, de sorte qu'il y ait une incitation économique à tenir un compte honnête des avoirs de chacun. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des Bitcoins toutes les dix minutes - un peu à la même manière d'un mineur d'or qui est récompensé par de l'or en échange de son travail.
Étant donné que Bitcoin n'avait aucune valeur lors de son lancement, il était extrêmement facile à miner et également gratuit d'envoyer des tonnes de transactions. En théorie, il s'agissait d'un vecteur d'attaque par déni de service (DoS). Une attaque DoS ou DDoS se produit lorsque les nœuds sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils plantent. Sur un jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau, donc un plafond de 1 Mo de données pour chaque dix minutes de temps de transaction a été codé en dur dans le logiciel - semant la première graine de la guerre civile Bitcoin . De 2009 à 2017, cette limite de 1 Mo sur le total des transactions était l'aspect technique le plus controversé du bitcoin.
Pourquoi est-ce important?
Une seule et simple transaction Bitcoin est relativement petite du point de vue des données, donc 1 Mo toutes les dix minutes donne environ trois à sept transactions par seconde avant que le réseau ne devienne trop encombré. Satoshi Nakamoto a plaidé pour un nombre de transactions au niveau de Visa, ainsi que son successeur direct en tant que développeur principal du projet, Gavin Andresen! Certains des premiers Bitcoiners influents comme Mike Hearn et Jeff Garzik ont ​​également plaidé pour plus de données par bloc pour permettre à Bitcoin de se développer pour rester un simple système de paiement électronique. Ils étaient pour des «gros blocs» contrairement au camp des «petits blocs» qui préconisaient une permanence de la limitation de 1 Mo de Bitcoin.
Le camp des "petits blocs" estiment que Bitcoin n'est pas un réseau de paiement, mais plutôt qu'il s'apparente davantage à une banque décentralisée conçue pour stocker des Bitcoins qui ne bougent jamais: une sorte de coffre-fort d'or numérique. Ils voulaient que la limite de taille des blocs de 1 Mo reste permanente sous les auspices de chaque personne exécutant un «nœud bitcoin complet» sans avoir à payer trop d'espace sur le disque dur. Cela signifierait qu'en période de congestion, les frais de transaction deviendraient absurdement élevés, mais cela n'aurait pas d'importance car le bitcoin ne devrait pas être négocié sauf en grosses quantitées de toute façon. L'autre problème est que s'il est bon marché de rejoindre la gouvernance de Bitcoin, alors le réseau est facile à attaquer par sybil, et je dirais que BTC est régi par des sybilles à ce jour.
Le camp des "gros-blocs" estime que tout le monde sur terre devrait être en mesure d'échanger et de faire ses affaires sur Bitcoin.
Les "petits-blocs" pensent que tout le monde devrait être en mesure de gérer soi-même le registre mondial chez soi, mais que seules certaines personnes très riches devraient pouvoir effectuer des transactions.
Après des années de querelles, en 2017, Bitcoin s'est scindé en deux chaînes distinctes, et en 2018, il s'est à nouveau divisé.
Alors quelle est la différence entre ces versions ?
BTC est actuellement la version qui a le prix le plus élevé, avec la plus petite taille de bloc et la plus grande puissance de calcul. Malheureusement, il est régi par des développeurs de logiciels et des sybilles qui contrôlent le consensus grâce à une utilisation intelligente de logiciels malveillants appelés «soft-fork» qui leur permet de saper les règles du Bitcoin. Ils utilisent ce pouvoir pour changer les règles des transactions en mentant aux nœuds et en leur disant de les valider quand même. Toute la culture BTC consiste à acheter du BTC afin de le conserver jusqu'à un moment dans le futur où il sera vendu. Les paiements avec BTC ou les transactions de toute nature sont méprisés.
BCH est un réseau basé sur Bitcoin qui pense que les blocs devraient être à peine légèrement plus grands, mais ils ont également des développeurs en charge des règles, tout comme BTC, et ils pensent que Bitcoin devrait être catégorisé pour être utilisé uniquement pour le commerce de détail, mais rien de plus. Le réseau change de règles tous les six mois. Les transactions non commerciales sont en général méprisées.
BSV est la version restaurée du protocole Bitcoin original avec tous les paramètres ouverts afin que les nœuds honnêtes puissent s'engager dans un consensus conformément au livre blanc de Bitcoin - par preuve de travail ! Le protocole est gravé dans la pierre afin que les développeurs de logiciels ne puissent pas bricoler les règles. Cela permet aux entreprises de planifier des décennies d'utilisation du réseau et d'investir en toute confiance. En tant que seul réseau bitcoin totalement sans autorisation, le commerce de toute nature est encouragé sur BSV. Tout, allant des réseaux sociaux aux expériences de science des données météorologiques ou aux tests de disponibilité du réseau, est encouragé. Paiements de détail, tokenisation, ou tout autre type de contrat intelligent est simple à déployer sans limitations. Bitcoin SV n'a aucun limite sauf l'esprit humain et l'esprit d'entreprise.
Et c'est la racine de la haine envers BSV.
Les "petits-blocs" ont investi toute leur réputation et leurs moyens de subsistance sur la notion que le bitcoin est incapable de s'adapter. Pendant des années, des experts présumés ont convaincu de nombreuses personnes que les limites de taille de bloc de 2 Mo, 8 Mo ou 22 Mo casseraient littéralement Bitcoin. Ils ont furieusement mis en jeux leur réputation sur ces fausses notions. Et ensuite, BSV a eu de nombreux blocs de plus de 100 Mo. En fait, il y en a même eu quelques-uns de plus de 300 Mo! prouvant que les petits-blocs se trompent sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie du récit de Bitcoin. Depuis 2015, lorsque le Dr Craig Wright est apparu sur les lieux pour expliquer que le bitcoin avait en réalité ZERO limitations, il a créé un tollé massif parmi l'intelligentsia des petits-blocs. Les leaders d'opinion de l'époque étaient payés pour prendre la parole lors de conférences où ils expliquaient à tort que Bitcoin n'était rien d'autre qu'une réserve de valeur rare sans autre utilité. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing et d'autres notions inconcevables (à l'époque) sur Bitcoin. Sa passion et ses connaissances se sont heurtées à des calomnies et des railleries. Ils se sont concentrés sur l'attaque de son personnage au lieu de discuter de Bitcoin!
C'est devenu l'une des principales méthodes d'attaque des petits-blocs. Lorsque de gros-blocs parlent des capacités de Bitcoin, ils sont ridiculisés en tant qu'escrocs et le sujet est toujours dirigé très loin de la discussion technique, car les petits-blocs savent bien qu'ils sortiraient perdants. Ils fouillent les dossiers personnels et cherchent des moyens de faire taire les gens du camp des grands-blocs de Bitcoin de la même manière que les guerriers de la justice sociale s'engagent dans la culture d'annulation contre leurs ennemis politiques.
Qui est le Dr Craig Wright et que fait-il?
Si vous ne le savez pas, Craig Wright est le scientifique en chef d'une société de recherche sur Bitcoin au Royaume-Uni appelée nChain : une société de 150 à 200 informaticiens. Craig dirige l'équipe qui étudie les possibilités de Bitcoin et de ses applications dans le monde. Il est l'un des experts en criminalité numérique les plus reconnus au monde avec les certifications SANS et GIAC ainsi que les titres GSE CISSP, CISA, CISM, CCE, GCFA, GLEG, GREM et GSPA. En outre, il est un polymathe multidisciplinaire de troisième cycle: un doctorat en informatique, économie et théologie et titulaire d'une maîtrise en statistique et en droit commercial international.
En 2015, il a également été exposé par une publication conjointe de WIRED et Gizmodo en tant que Satoshi Nakamoto, le créateur de Bitcoin. Quelques jours après cette révélation, les gens qui le soutenaient ont vu leurs clés d'accès au code révoquées, et de nombreux autres ont été instantanément bannis. Craig a été mis sous enquête par le bureau des impôts australien pour ce qu'il considérait être une erreur de comptabilisation probable de ses bitcoins. Les retombées ont été agressives et rapides, avec une gigantesque armée de petits-blocs, organisée sur Reddit et autres forums, et nouvellement financée par l'argent de la startup pro-petits-blocs appelée «Blockstream». Leur message était clair: Bitcoin doit garder de petits blocs. Le Bitcoin ne peut pas évoluer, et toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage.
Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que Dave était plus impliqué qu'il ne l'était réellement, et l'affaire est en cours actuellement, jusqu'à courant 2021. Ira Kleiman pense que Craig est Satoshi et a investi une fortune incalculable et a obtenu l'argent d'investisseurs extérieurs pour poursuivre sa poursuite. Il est clair que les bailleurs de fonds d'Ira pensent que Craig est également Satoshi.
Les critiques qualifient souvent la révélation publique et le procès public de Wright de ternir énormément sa réputation, mais il convient de noter que les deux sont arrivés à Wright et qu'il ne souhaitait clairement pas être pris dans l'une ou l'autre situation.
Au lieu de cela, Craig est un défenseur passionné de la vision d'un Bitcoin avec de gros blocs, appelant à la professionnalisation, à la légalisation et à l'utilisation mondiales de Bitcoin pour une utilisation à tous les niveaux du commerce. La réponse à la passion de Craig et à ses affirmations a été d'attaquer sa réputation et d'endosser Internet avec le surnom de «Faketoshi». Lorsque de simples brimades ont échoué contre le Dr Wright, des attaques ont été intensifiées pour remettre en question ses divers diplômes, des pétitions aux universités pour enquêter sur lui pour plagiat dans divers travaux, y compris des thèses de doctorat, etc. Wright a même revendiqué des menaces contre la vie des membres de sa famille et il y a plus qu'une petite preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, vraiment, des gens sont morts».
Les attaques en cours
Cela ne peut être assez souligné: la communauté des petits-blocs est construite autour de tactiques d'ingénierie sociale professionnelle. Gregory Maxwell, co-fondateur de la société Blockstream, a été formé à la pratique de l'ingénierie sociale et l'a utilisé de manière si subversive comme un outil de propagande pendant son mandat en tant que modérateur rémunéré de Wikipedia, qu'il a finalement été démis de ses fonctions avec les journaux d'administration citant une litanie d'infractions, notamment:
«Gmaxwell s'est engagé dans la création de faux comptes en masse…» - Alhutch 00:05, 23 janvier 2006 (UTC)
«Menaces, insultes grossières, usurpations d'identité d'un administrateur», -Husnock 03:18, 25 janvier 2006 (UTC)
«Son comportement est scandaleux. Franchement, il est hors de contrôle à ce stade. Son comportement d'intimidation doit cesser.» - FearÉIREANN 19:36, 22 janvier 2006 (UTC)
«Sa liste de contributions est hors de propos. C'est du vandalisme. C'est un comportement auquel je m'attendrais d'un éditeur en furie, ce que, franchement, Gmaxwell est.» - Splashtalk 20h00, 22 janvier 2006 (UTC)
«Prétend être un administrateur, menaçant de bloquer les personnes qui ne sont pas d'accord avec lui, fait régulièrement des attaques personnelles» - SlimVirgin (talk) 12h22, 22 janvier 2006 (UTC)
Il passe beaucoup de temps sur Reddit et d'autres forums à semer la peur sur les dangers des gros blocs, et il a été surpris en train de faire semblant d'être plusieurs comptes à la fois en train d'avoir de très longues discussions techniques sur Reddit destinées à submerger les nouveaux arrivants avec ce qui ressemble à un débat intellectuel.
Qui d'autre est attaqué?
L'autre cible commune de la machine de guerre anti-BSV est Calvin Ayre: le milliardaire à la tête de l'empire du groupe Ayre. Calvin est un entrepreneur canadien et antiguais qui a lancé un incubateur Internet à Vancouver au tout début du boom Internet. Fils d'un éleveur de porcs, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu d'argent sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines compliquées et obsolètes en poussant les limites dans les marchés gris qui existent où les dollars américains sont utilisés à travers les frontières pour s'engager dans un commerce juridiquement compliqué comme le jeu d'argent. Son travail dans ce domaine lui a valu une petite fortune et un passage sur une liste des «plus recherchés» pour blanchiment d'argent. C'est un point sur lequel les petits-blocs aiment se concentrer, mais ils le sortent complètement de son contexte. Calvin a finalement plaidé coupable à une accusation de délit, mais a été le fer de lance de la modernisation des lois et règlements américains qui existent aujourd'hui sur les marchés complètement ouverts et fonctionnels. Il est respecté pour son travail dans l'industrie du jeu, les médias et la philanthropie. Calvin est certainement le bienvenu aux États-Unis malgré la critique souvent citée et dépassée selon laquelle il est une sorte de hors-la-loi.
Calvin Ayre
Dans l'économie Bitcoin, Ayre est une figure de proue dans la gestion de nœuds Bitcoin honnêtes pendant plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups dans l'espace BSV. Bien qu'il soit probablement le plus gros investisseur, il n'est pas le monolithe que les petits-blocs laisseraient croire aux critiques. Il est important de comprendre que des segments entiers de l'écosystème BSV existent complètement en dehors de son influence.
Twetch, par exemple, est une entreprise indépendante appartenant à l'écosystème BSV, célèbre pour ses attaques contre les médias sociaux centralisés. Ils sont même connus pour se moquer des entreprises qui acceptent l'argent d'Ayre, en plaisantant que Calvin possède tout sauf Twetch. Bien sûr, ce n'est pas vrai. Un autre excellent exemple est l'investisseur / entrepreneur indépendant Jack Liu : ancien dirigeant de Circle et OKEX. Liu possède la marque de hackathons CambrianSV ainsi que des propriétés précieuses dans l'espace BSV telles que RelayX, Streamanity, Output Capital, FloatSV et Dimely.
Les autres acteurs clés sont MatterPool Mining et leur écosystème Mattercloud: une joint-venture entre des acteurs indépendants de l'écosystème BSV, avec des connexions directes aux protocoles BoostPOW et 21e8 et des relations avec des développeurs BSV indépendants.
Bien sûr, il existe également des marques précieuses financées par Ayre. Il s'agit notamment de la propriété partielle via l'investissement dans HandCash, Centi, TonicPow et Unwriter's Planaria Corp.
Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage. Alors qu'à un moment de l'histoire, les entreprises appartenant à Ayre représentent une quantité importante de hachage sur bitcoin, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup sont ennemis. Ces mineurs soulignent cependant la nature ouverte et sans permission de BSV pour permettre à quiconque de participer.
Ayre est un acteur important, mais en aucun cas un contrôleur de la direction de la blockchain ou des entreprises indépendantes dans l'économie BSV.
Mais pourquoi Craig poursuit-il tout le monde en justice ?
Tout d'abord, et c'est crucial, le procès le plus important de Craig est l'affaire Kleiman. Les autres cas existent uniquement à cause de la diffamation publique du Dr Wright. Le hashtag #CraigWrightIsAFraud circule largement, poussé en grande partie par un mélange de personnages anonymes sur Twitter. Plus particulièrement Magnus Granath AKA «Hodlonaut» a été averti qu'une accusation publique de fraude courait à son encontre. La carrière du Dr Wright est en informatique et en criminalistique numérique, donc le déclarer publiquement une fraude cause un préjudice financier au Dr Wright dans son domaine d'expertise commerciale. Puisque «Hodlnaut» a refusé de cesser, on lui a envoyer une requête pour être vu au tribunal. Cela a causé le célèbre podcasteur de petits-blocs Peter McCormack à mendier d'être poursuivi aussi - en augmentant la rhétorique diffamatoire contre le Dr Wright. À la demande de McCormack, il a lui aussi été attaqué en justice pour être vu au tribunal.
Cette ère de service a engendré la campagne #DelistBSV menée en grande partie par «CZ», le PDG charismatique de Binance Exchange. Divers autres échanges comme Shapeshift et Kraken ont publié des sondages publics demandant s'ils devaient emboîter le pas, et des petits-blocs bien organisés ont voté en masse pour retirer BSV de leurs échanges - citant la toxicité du Dr Wright pour avoir intenté des poursuites en diffamation contre Hodlonaut et McCormack. Finalement, BSV a été retiré de Binance, ShapeShift et Kraken. Il a également été noté publiquement par Coinbase et Gemini qu'ils ne soutiendraient pas du tout cette version de bitcoin à la suite du drame public.
Au fur et à mesure que les choses progressaient, le fondateur de Bitcoin.com, Roger Ver, a également réalisé une vidéo publique déclarant Wright comme arnaqueur. C'était après avoir travaillé sournoisement avec les développeurs Bitcoin ABC pour coder des points de contrôle dans le logiciel ABC de Bitcoin Cash, divisant de manière permanente le réseau Bitcoin pour la deuxième et dernière fois - un acte pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que des problèmes juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais les critiques publiques ont persisté jusqu'à ce que Roger soit également entendu devant le tribunal et fournisse la preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Son cas est en instance à Antigua-et-Barbuda, où il est récemment devenu citoyen.
Et ensuite il se passe quoi ?
Nous avons établi l'histoire du Bitcoin, de la guerre civile, des attaques publiques contre Wright, Ayre et BSV. Au moment d'écrire ces lignes, nous pouvons revenir sur les attaques contre Thomas Lee, Tim Draper et Jimmy Wales pour avoir eu une proximité avec BSV. Malgré la pression sociale, le rapport Fundstrat de Lee a rendu un examen élogieux du protocole fixe et de l'évolutivité infinie de BSV. Lee et son équipe étaient heureux de prendre la parole lors des événements précédents de CoinGeek, même après le tollé public.
Pour la conférence CoinGeek 2020 à New York, McCormack, Hodlonaut, « Arthur Van Pelt » et d'autres acteurs tels que le Dan Held de Kraken et une cacophonie de trolls anonymes sur Twitter ont mis à profit leur expérience de la culture d'annulation à la bolchevique pour faire pression sur les orateurs Gary Vaynerchuk , et d'autres orateurs prévus afin de les forcer à annuler leur participation à la conférence. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un cas gigantesque de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin SV sont en quelque sorte dangereux, alors qu'en fait, le protocole et le réseau sont imperméables à toutes les attaques, à l'exception de leur ingénierie sociale.
Bitcoin SV s'est développé professionnellement avec un portefeuille de brevets de classe mondiale. Il est utilisé par des entreprises indépendantes pour réaliser des profits et il est exploité sur le marché libre par un groupe décentralisé de nœuds honnêtes qui se font concurrence. Le réseau est fixe, sécurisé et en croissance grâce aux investissements de petites entreprises et de gestionnaires de capitaux mondiaux. Les mensonges au contraire sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaie qui craignent l'adoption mondiale de BSV comme outil de commerce et ce que cela signifiera pour eux. L'histoire ne sera pas gentille avec ces manipulateurs et leurs réseaux qui sont financés par les fraudes probables des échanges de crypto-monnaies off-shore, le (très probablement) frauduleux Tether Stablecoin, et l'économie de "pump-and-dump" qui sous-tend 95% du volume de négociation de l'ensemble de l'économie cryptomonnaie actuelle.
C'est une guerre civile. Il y aura toujours des victimes, mais alors que BTC et BCH se concentrent sur les ragots et les affaires illicites, BSV veut que le monde entier soit plus libre, plus souverain et plus capable de coopérer sur le registre mondial de la vérité afin que les entrepreneurs du monde puissent s'engager dans les grandes entreprises ou de simples nano-services sont rendus possibles uniquement par Bitcoin. Bitcoin est un test d'intelligence. Au fil du temps, les personnes intelligentes pourront voir à travers le brouillard de distorsion de la réalité créé pour confondre les innocents et reconnaître cela pour ce que c'est, une attaque coordonnée pour tenter de supprimer une technologie supérieure qui les rendrait obsolètes.

Step by Step Guide to Starting Smart Mining of ViaBTC

Step by Step Guide to Starting Smart Mining of ViaBTC
In order to help our miners to get the best possible profits, now we present you the step by step guide to starting Smart Mining of ViaBTC. No time for hesitation, try Smart Mining now!
Smart mining consists of two different mining modes, namely as “Manual Switch” and “Auto Switch”.
Auto Switch provides an automated way of profitable mining using the designated algorithm to monitor the real-time status of possible returns. In comparison to manual switch, it’s more flexible and easier to keep tracking of your mining returns.
1.
Enable Auto Switch
It now supports BTC、BCH and BSV, besides, your assets in your account can also be converted into BTC on an hourly basis automatically.
Before enabling auto switch mode, you’re required to configure smart mining URL: stratum+tcp://bitcoin.viabtc.com:3333;
Enable Manual Switch
This supports Bitcoin pool (BTC, BCH, BSV, FCH) and Ethereum pool (ETH, ETC).
One-click switch address is different from the stratum URL for a specified coin. Details for one-click switch URL are listed as following: BTC/BCH/BSV/FCH: stratum+tcp://bitcoin.viabtc.com:3333 ETH/ETC: stratum+tcp://ethereum.viabtc.com:3333 Noted: Port 25 or 443 is available as an alternative option.
2.
Go to www.viabtc.com then click [Settings] from the drop-down menu on your right hand side.

Select “Mode” and “Coin Type”
https://preview.redd.it/7zmjh3ienm551.png?width=1400&format=png&auto=webp&s=2c2ff5f99265402def95717f4a28de71ffe17b32
Frequently Asked Questions
What is the unique feature of Auto Switch compares to Manual Switch? It’s more flexible and easy to set up, SHA-256 mining algorithm compatible.
How long will it take to be activated after enabling Auto Switch? Once Auto Switch is on, system will monitor the possible return rate of all compatible coins using a designated algorithm and switch to the one with higher profits, you may go to the Pool panel for more accurate mining status.
Why I can’t see my earnings increased after enabling Auto Switch mode? Auto Switch mode demands high-efficiency when it switch between the current mined coins to the new one with possible high returns, specified using designated algorithm and current difficulty, thus it’s not a guarantee pass for high returns when “Auto Switch” is on.
Is there any requirements of MIN. limit of hashrate before enabling Auto Switch? There is no minimum limit of hashrate in your account before enabling Auto Switch in your account.
Which type of coins are supported in Auto Switch mode? Currently all types of coins in Bitcoin Pool are supported in Auto Switch mode, including BTC, BCH and BSV.
When will the mining rewards distributed to my account? Rewards distribution are varies for different mining modes, and distribution time remained unchanged compares to the one in Manual Switch mode.
Can I use part of hashrate to mine a designated coin after enabling Auto Switch? After enabling Auto Switch, hashrate connecting to your account will switch from one to the other automatically using a designated algorithm.
Will I receive hashrate fluctuation notification after enabling Auto Switch? You’re required to set hashrate fluctuation notification for all compatible coins by the time enabling Auto Switch, more detailed guideline can be found here.
How to check your current mining preference?
Go to www.viabtc.com first then enter [Pool] panel to check your current mining preference.
When should I change my mining preference?
It is recommended to use profit calculator to get a general idea of the theoretical earnings outcome when selecting mining preference.

Trade Bot Mining - the value proposition for the ANY token

At first glance the ANY token looked completely worthless to me from a tokenomic standpoint. It had a very low initial supply and was launched in a constant product market which quickly injected the value due to the high demand of hype. In seconds it reached about 350x evaluation compared to its proposed starting value, after quickly stabilizing at around 100x.
Further its only planned pairing is with FSN, the main liquidity providing token for the AnySwap Exchange. A situation that would mean the the FSN in the FSN/ANY pool would likely be decreasing as more and more coin pairings are added to the AnySwap Exchange. A situation that's absolutely super bearish for ANY.
To top this off ANY has very heavy reward handouts every Fusion block (8.5 ANY every block, which is 3 times as much as FSN, for example).
The rewards are split between liquidity miners, AWN nodes, swap traders, AnySwap Company, and AnySwap team.
All these handouts are surely bound to add extra selling pressure on ANY.
The only apparent value ANY has is as a governance token. That holders of ANY hold actual power over the exchange. Deciding which coins to list, and who gets to run the AWN nodes as well as decisions regarding general direction and policy of the exchange. But can this power truly make up for all the selling pressure? It is doubtful... Especially since quite a bit of the ANYs ended up in very few hands, making it less 'democratic' than many had hoped for.
So is there ANYthing else that could save ANY? A day into the exchanges history we've seen two interesting things that might actually save ANY and it comes from quite an unexpected direction.
  1. There seems to be quite a high interest among CEXs to list ANY. One of which even has offered to provide a high amount of liquidity on AnySwap Exchange.
  2. Trading bots have began to "swap mine" ANY, by swaping FSN and ANY back and forth in order to grab the 2.5 ANY awarded swap traders every block.
Quick calculations showed that these bots (atm) are yielding several 1000x returns/year. Of course this can't hold up as more pairings gets added, the price of ANY droping and more bots enter the swap frenzy competition. CEXs are the masters of trading bots and they are probably quickly going to push their bots into DEXs if that is where the new action happens, and especially if there's great chances of making profit.
But what happens when the equation stops adding up. When trading volume has reached the point of those 1000x returns barely looking like a 1x. Well... at that point the practice is probably so established that the action just keeps going and eventually pushes the price ANY up so that it becomes profitable again (exactly in the same way as Bitcoin value is backed by the the cost of its mining operations).
It isn't certain this is happening. But there is some potential that ANY could become the 'Bitcoin' of "swap bots".

Building an Ethereum Mining Rig - Part 2

First update to the guide "Building a 6Gpu Mining Rig for Ethereum" - Let's talk about Claymore.
This update supplements and does not replace the Guide to Build a 6GPU Mining Rig for Ethereum published on our site.

The substantial differences are due to the installation of the latest version of the Windows 10 Operating System, the mining on the Ethermine pool (in our opinion simpler than Dwarfpool) and the use of the XFX RX 580 8gb GPUs.

The first variant is found in Part 4 of the guide: the environment variables are not to be entered as they will be integrated directly into the bat file to start mining.

The second variant is found in Part 7 of the guide and leads us to "mine" on a different pool using the Claymore software.
Download the latest version at the following link: https://github.com/Claymore-Dual/Claymore-Dual-Miner

Once downloaded, unzip everything on a folder on your desktop and open the start.bat file with notepad. Clear the contents and copy the following command:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where instead of "your wallet address" you will have to put your Ethererum wallet - obviously without the quotes - and instead of worker you will put an identification number in case you build more RIGs (such as RIG1, RIG2, etc ...). We opted for the eu1 pool even if some on the discussion forums believe that the us1 is more profitable.

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner


The Ethermine pool offers a very well crafted and descriptive interface. In the Payouts section, after only 5 minutes of mining, you can decide the minimum amount of Ether to be transferred to your wallet by simply entering the IP address of the RIG.

We have decided to mine directly on the Ethereum address of our Exodus wallet. It is not recommended to mine directly on Coinbase, as reported on the site itself. Sin.

Nothing should be left to chance when you decide to build a mining rig for Ethereum.
The third variant is the most difficult of all. Once you have reached Part 5 of the guide, you can decide whether to continue or follow this update / variant. If you are here it is probably because you have run into some problem that the guide does not allow you to solve.

With the latest version of Windows 10, you may run into a kernel conflict between the operating system and AMD's Radeon Software Crimson ReLive Edition Beta for Blockchain Compute drivers. This conflict will prevent you from using Atiflash after installing the drivers.

Important: Before making any changes to the BIOS, please backup each GPU.

Important: first of all flash the GPUs with the original bios if for any reason you are forced to reinstall the operating system.


Still on Atiflash.
The advice would therefore be to flash the GPUs and then install the AMD drivers. Let's say it would be because you may run into another problem this time related to the GPUs themselves. Since each video card is different from any other, the bios mod of the GPU could crash the operating system showing the classic blue screen and displaying an error related to the Atimkdag.sys file.

This could be due to the fact that some GPUs have significantly higher performance in the calculation phase than others. We could call it a factory overclock but not using them for gaming we cannot say it with absolute certainty.

Having assessed these two drawbacks, the only safe solution is to flash all the GPUs, disconnect them except for the first one, install the Blockchain drivers (plus Atimkdag patch) and launch the mining command verifying that the operating system does not go into crash in the next 5 minutes.

Turn off the rig again and connect the second GPU so on up to the sixth. In the event that one or more video cards should crash the system, disconnect them. After that, it uses DDU from the provisional mode and flashes these GPUs with their original bios. At this point, connect them again, reinstall the Blockcain drivers (plus Atimkdag patch) and start mining definitively.

All the operations related to the use of Atiflash, DDU and driver installation are reported in Part 5 and Part 6 of our guide.
A little bit of Overclocking.
You will certainly find significant differences in performance between the GPUs.

At this point all that remains is to "operate" with an overclocking software. We opt for OverdriveNtool. Our constantly updated guide is available at the following link: https://www.cryptoall.it/2019/10/12/complete-guide-to-overdriventool/

Link to the official YouTube channel for verification: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

GPUs with modified bios will not leave much room for modification. You will have to proceed with the most extreme overclocking on those that mount the original bios; obviously always in small steps by saving the profile for each GPU. Our guide explains in detail how to do it.

Hoping to have been of help, we give everyone an appointment for the second part of the update on how to build an Ethereum mining rig in which we will explain in detail the dual mining on the Ethermine pool.

See you soon.

Learning about Bitcoin - including mining

I've been buying Bitcoin for a while mostly in a 'fad' state of mind; it's tomorrow's technology and hopes of making profit. But recently I've had new perspective after seeing how the world uses Bitcoin especially in Venezuela/Hong Kong and how the US treasury/federal system is spending money. So I've been reading and understnading Bitcoin more and wanted to learn about mining. I'll preface that I'm not in this to make money (I'm mostly a few years late anyways) but I want to learn more of the technology.
I'm mining with my GPU at the moment under a mining pool. My hashrate is about 9Mh/s which I'm not sure what that fully means. Am I computing 9000 'hash-computations per second towards finding the next block? I understand that a GPU will calculate solution faster than a CPU, but what should I be getting out of a GTX 1060 3GB for hash rate? Is there a way to optimize connection to the network?
https://imgur.com/a/ga94sSJ
Mostly any information would be helpful. I can follow directions on how to set up mining, but I want to know more about the inner workings and the hardware technology that goes along with it.

What Can We Expect in the Halving Market? 58COIN Exchange Beauty Executive Gives the Answer

What Can We Expect in the Halving Market? 58COIN Exchange Beauty Executive Gives the Answer


What are the effects of the third Bitcoin halving?
How to view the relationship between mining pools and exchanges?
Is the contract a road of no return?
What is the future trend of digital currency?


Q1: What does 58COIN expect from this Bitcoin halving?
Xiao Bei: On the macro level, reduction in the bitcoin production shows a more stable signal to the market. May 12th is the third halving in bitcoin’s history, before it, however, the daily production plunged from 1800 to 900, a reduction of around 30,000 bitcoins in a month. The selling pressure reduced significantly, which leaves the root impact on the gradual stability of the market.
The reduction not only brought us a bull market with a sustainable and long-lasting effect but greater opportunities as well. As an exchange, it should better improve itself and render stable and quality products to users. Currently, 58COIN’s mining pool ranks the top 5 in the world. After the reduction, based on the principle of survival of the fittest, the superior resources will be allocated to a larger and more stable mining farm, and the steady recovery of computing power is also anticipating.
Q2: As an exchange, why does 58COIN occupy more than 10% of the overall bitcoin’s computing power?
Xiao Bei: At present, our computing power share is about 7.8%, ranking among the top five in the world. Our recent goal is to have a stable computing power share of more than 10%.
The mining pool provides the main non-trading BTC source for the exchange, increases the supply of BTCs on the market, and injects liquidity into the market. The top ten exchanges are expected to receive more than 70% of the bitcoin in the mining pool, so all major exchanges have begun to layout the mining pool to compete for BTC.
58COIN has reorganized the layout and started the operation of the new mining pool (58COIN& 1THash) in 2019. We have a mature operation team with more than 6 years’ experience, and hope to better link the upstream and downstream industries in the next stage. This is also an important step in the strategic development of high-quality exchanges.
Q3: For an exchange, liquidity and redemption abilities are the absolute reflection of the user's sense of security. How does 58COIN ensure these two abilities that users care most?
Xiao Bei: In terms of liquidity, first of all, our registered users have exceeded 3 million, which provides sufficient trading liquidity and depth. Secondly, our matching transaction service with constantly upgraded technology and algorithm ensures that each matchmaking time is in the microsecond level, and easily achieve system 10,000-level throughput performance.
Concerning the redemption ability, non-trading digital assets held by the exchange serves as the foundation. The advantages of 58COIN's mining pool have accumulated abundant platform reserves for us. As of now, our risk reserve has exceeded 3.6 billion yuan.
Besides, the Exchange integrates account opening, transaction matching, and liquidation, and plays an important role in the secondary market. Most exchanges lack a high-quality intelligent risk control system, a comprehensive anti-money laundering mechanism, and insufficient open and transparent information disclosure and supervision. There may be acts of forgery of trading volume, joint price manipulation with the project party, and other actions that harm the interests of investors. If the liquidity itself is not good enough, the situation mentioned above is more likely to occur.
Q4: Which section does 58COIN values most? Contract Trading or Spot Transactions? What is the biggest advantage of trading contracts on 58COIN?
Xiao Bei: Both spot and contract boast their own advantages, separately lie in the exchange value through hoarded coins, and flexible use of fluctuations. 58COIN as the main contract exchange, contract trading is definitely our focus. In terms of spot, it is mainly based on mainstream currencies.
Compared with spot trading, the two-direction trading mechanism is more flexible. Also, leverage can increase the utilization rate of funds and amplify the profit, which is suitable for users with fewer funds to trade.
The biggest advantage of contract transactions, in addition to the just mentioned abundant platform reserves, complete risk control and huge user base, there are several points related to the user's vital interests:
  1. The lowest fee in the industry. For example, the handling fee of the perpetual contract is: “Taker 0.03%, Maker 0.015%”;
  2. The fixed maintenance margin of 0.5%;
  3. No funding fees. We have made every effort to reduce the principal consumption in each exchange, thus greatly lower the risk of liquidation;
  4. The platform insurance funds bear the full debt loss, and users do not have to worry about apportioning any risks.
In addition, the contract can also maintain the value of the existing mainstream spot of the user to minimize the risk of depreciation caused by spot fluctuations.
It is worth mentioning that in terms of wallet, we implement multi-level and multi-dimensional security risk control strategies such as hot and cold wallet isolation, multi-signature authorization, and regularly change of hot wallet addresses. Meanwhile, a manual verification process was added to ensure the safety of the assets. Since its establishment, there has never been any wallet accident, wallet stolen, or the loss of coin incidents.
Q5: In the contract transaction, what advice does 58COIN give to novice users?
Xiao Bei: Firstly, please remind that contract is not a devil, it is just a tool. What we should do is to make good use of the tool to make profits.
Secondly, the purpose of the investment is to withdraw, and suggestions are shown below:
1. Invest with the spare funds at hand;
2. In the spot transaction, hoard coins in the bear market and exchange in the bull market, do not follow the trend of buying in the bull market;
3. In the contract, set up operation points and positions, and perform secondary operations according to market conditions. (Do not be greedy)
4. Make a risk response plan during the investment process, such as a sufficient margin, value preservation plan, etc.
Finally, we must keep in mind: when doing spot transactions, choose assets with good liquidity in a way to get away from manipulation projects, risky exchanges, etc.
58COIN provides detailed descriptions for each business line, novice users should read them carefully before using. Besides, each contract trading page is designed with a calculator to help provide trading references to users before investment.
Q6: What are the new plans of 58COIN?
Xiao Bei: First of all, we will remain a sophisticated attitude in technology, risk control, and product experience, offering a stronger guarantee for users' transactions; second, we will further improve the ecological layout of 58COIN, from increasing investment in mining pools, gradually optimizing the hot and cold wallet system, enabling entities, focusing on community construction, etc., with better technical upgrades and preparations, to ensure that the entire 58COIN ecology can better link the upstream and downstream industries, providing our users with a more stable ecological background; We will launch some online activities in the near future, covering basic knowledge, candlestick chart learning, and industry analysis. We look forward to making joint efforts with our users in learning and making progress.
Q7: What does 58COIN want to say about the future cryptocurrency market?
Xiao Bei: The real big bonus in the cryptocurrency market has not yet been released, and Bitcoin has more imagination space than gold in the future. The cryptocurrency market is stepping toward a diversified, professional, and tangible direction, requiring more high-quality industries participation and landing. Though it is currently the fastest-growing field, financial attributes should not be the only factor entitled to cryptocurrencies, the future market should be more integrated and serve the real economy, such as the Internet of Things, financial systems, and personal privacy.

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth
With the development of blockchain technology, obtaining data on the chain only is no longer satisfying and how to bridge the real world and the blockchain world has always been the direction of the technological breakthrough. Under this background, Oracle Machine came to our attention. In particular, with the popularity of the DeFi concept, the industry starts to witness a boom of the application of Oracle Machine in financial derivatives, trading platforms, gambling games, and prediction markets.
At present, Oracle Machine represented by Themis is developing fast with a good momentum, leading the trend of the development of Oracle Machine and continuing to consolidate the basic technical support for the DeFi revolution. Themis’ mining system has been launched in the market, which is refreshing and appealing (see https://themisoracle.com/#/credit for details on the Themis mining).
90% of MIS, the native token of Themis, will be used for mining output. The entire mining mechanism runs through a distributed oracle protocol, which sets up three roles: data provider, data validator, and arbitration node. Reward and punishment mechanisms are applied to ensure the smooth ecological operation.
How does Themis mining work? Is it a new way to become wealthy? What are the characteristics? To answer these questions, we need to analyse the distribution mechanism, mining mechanism, and token value of Themis.
With a fairer mining mechanism, small and medium-sized miners can enjoy better benefits
One of the core values of blockchain is fairness and justice, and allowing everyone in the network to play a role in the system without permission. However, Bitcoin mining is now monopolized by several mining machine vendors such as Bitmain, leaving little space for other miners to participate. If those old PoW public chains, such as Bitcoin, has formed the head effect in mining, what about those new projects? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked top with the strong financial strength and user base of the top exchange, making the small and medium nodes hard to participate.
After comparison, we can find that the mining mechanism of MIS is very friendly to ordinary users. Assuming that there are 12 mining transactions in a block, the ranking according to the MIS pledged by each transaction would be as follow:
https://preview.redd.it/1kfccgps2pg51.png?width=832&format=png&auto=webp&s=bf6c7f614c600826006bc2bf8a6026292c3b328c
The pledge ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user pledge amount, which can prevent MIS from being controlled by a small number of people, avoid monopoly, creating a win-win situation in the Themis community.

https://preview.redd.it/pme9tcd62pg51.png?width=832&format=png&auto=webp&s=049f899d2a5ee3ce64007d5cc0ae3ed6167c2b3a
Compared with other mining projects, Themis has introduced a unique pledge ranking method in the mining design. Users in the best ranking area will get the most benefits, which is a good mechanism guarantee for attracting more users to participate in mining. At the same time, it can lead to the decentralization of data providers, ensuring the decentralization of the oracle system and the positive development of the community.
How can miners join in Themis mining? The answer is to become a part of the ecology by playing the role of either data provider, data validator, or arbitration node.
The data provider is mainly responsible for providing various types of data, and the data validator verifies and challenges the data offered by the data provider and provides new data. The arbitration node arbitrates the query raised by the data validator and come up with the final result.
Both the data providers and validators of Themis need to pledge MIS to obtain the qualifications, and the caller of external data also needs to pay MIS assets when accessing the data of Themis oracles. If the data has been verified as correct, data providers and validators will receive mining rewards, and the more they pledge, the more rewards they will receive.
In the mining design of Themis, miners can acquire MIS by providing verifiable random number or offering the price of in-chain assets. Whenever miners call mining contracts, the system will charge no service fee (excluding the service fee of ETH). In addition, if no mining transaction occurs within a certain period of time, the first newly-emerging block containing mining transactions will acquire all the MIS rewards. In this way, miners can be encouraged to continue mining and maintain the ecological stability of Themis.
The number of MIS mining for each mining transaction of miners is calculated as follows:
First, calculate the number of MIS mining rewards N contained in the block of the packaged mining transaction. If the height difference between the block and the previous block containing the mining transaction is y, then N = y * 20.
The MIS mining quantity of this mining transaction is M, then M=Xi/(📷)×N. Among them, X is the ranking of the MIS pledge amount in the block, and those who pledge the same amount of MIS have the same ranking.
Few official pre-mining, while 90% belongs to the community
Based on the official announcement, the distribution of MIS is:
The total amount of MIS is 1 billion, 10% is reserved for early project promotion, the remaining 90% are produced by mining, in which 75% are directly awarded to data providers, 10% to developers, and 5% as reward for arbitration nodes and ecological incentive. The production of mining will be progressively decreased and released with ETH. For some current popular VC-invested projects, institutional holdings hold more than half of blocks and unlock the block every month, which is a huge stress for ordinary pledge users. Many projects also went wrong because institutional investors do not abide by the rules. For MIS, because there is fewer official pre-mining, the selling pressure will be smaller, which is more in line with the value of the blockchain.
The release plan of developer and arbitration node and ecological incentive is as follows:

https://preview.redd.it/nld8k8gb2pg51.jpg?width=926&format=pjpg&auto=webp&s=8c2435c993cf86b2bf6b0c4d2a1935708734de97
The release plan of data provider incentive is as follows:

https://preview.redd.it/kgia5n6d2pg51.jpg?width=982&format=pjpg&auto=webp&s=ad1bfe7796fdaec58f3caede2f2a2083c0a07724
The MIS awarded per block reduces by 10% in every 4 million blocks, and the reward per block at present is 20 MIS.
We can see that the allocation of MIS follows the following principles.
First of all, as MIS is the platform certificate of Themis, it is very reasonable to reserve 10% of MIS for early project promotion.
Secondly, 90% of MIS is produced through sustainable mining. This proportion can motivate contract users and miners to conduct contract mining, truly implementing the spirit of win-win community and token economy.
Finally, among the 90% of MIS, better incentive mechanisms have been adapted, mining reward ratios are subdivided, which can attract more investors to participate in mining.
Reasonable mining mechanism highlights the project value of Themis
Themis, as a public chain that provides a mechanism to solve the problems in Oracle Machine, has a unique charm in the value of MIS.
From the perspective of the number of tokens, the total amount of MIS is 1 billion, and the total mining pool is 900 million. 90% of the tokens are generated by mining, and the mining output gradually decreases its release with the Ethereum block, showing a great potential in its future added value. The earlier you participate in mining, the more profit you can gain.
From the perspective of Themis’s ecological design, Themis is committed to the original intention of building a price oracle. The data provider pays on-chain fees and pledges a certain amount of MIS, and determines the income obtained according to the scale of the pledge; the validator can make profit from challenging the data. Also, any smart contract developer or user need to pay the corresponding fee when calling Themis, and this part of the profit will be distributed to the data provider in proportion. Through this design, a logical closed loop is completed to ensure the healthy operation of the entire ecology and achieve the goal of mutual benefit. In Themis, all parties in the ecology can work together to grow more wealth.
In all, MIS has a huge potential for future development and arbitrage, and of course, a great profit potential as well.
Today, public chains like Themis are not just a technology platform, but also a symbol of future economic operation mode which connect between the blockchain and the real world. Themis, with a fair, justice and open network through mining, is building a strong token ecology, connecting external chain data and the systems, realising data interaction between blockchain and the real world, and more importantly, creating a new mode of token economy.

08-10 07:44 - 'Who is forking Filecoin?' (self.Bitcoin) by /u/paulcheung1990 removed from /r/Bitcoin within 6-16min

'''
Forking Filecoin is a $500 million to $1 billion business?
On July 17, cryptocurrency analyst Bitfool mentioned via Weibo: “Recently, people who forked Filecoin in the market have been undercurrents; as far as I know, there are 4-5 teams. From a strategic point of view, the project Teams, investors, and miners get two of the three to successfully fork; one of the three can steal 5-10% of the market value. Therefore, Filecoin's fork is a $500 million to $1 billion Business."
"It's even more awesome, full of courage, and ready to build a team to fork Fliecoin. Well done, famous in the world, poor done, and scorned by thousands of people."
Sun Ming, a partner of Fenbushi Capital, mentioned in an interview: "Miners who have invested a lot of hardware resources are promoting the fork of Filecoin.
Hu Feng, operating partner of the FILPool mining pool, said: "Currently, big miners have ideas, but it will only be possible after the mainnet is online.
Filecoin economic model is not friendly to miners
At the beginning of the establishment of the Filecoin economic model, a pledge and reward and punishment mechanism was proposed, which has undergone many adjustments. The last three adjustments have made the mechanism increasingly stringent.
In April of this year, the Filecoin project team introduced their thinking on the economic model and refined the reward and punishment mechanism. Miners who complete file storage can get corresponding block rewards, and fail to store files within the promised period will be punished. This fine is imposed on the Filecoin collateral pool (locked funds) provided by each storage miner. Locked funds include a small amount of early FIL tokens and token rewards obtained from miners.
Miners need to mortgage a certain amount of tokens in the early stage. If the amount of mortgage is too large, it will cause a shortage of FIL tokens in the early stage. The improvement made by the economic model is to transfer some of the early-stage costs to future block rewards.
The severe punishment mechanism made some miners dissatisfied, and some miners commented that the mechanism was too "crude".
In May, Filecoin made major adjustments to its economic model. This adjustment raises the threshold for miners to leave. Filecoin continues to strengthen the miner's mortgage mechanism, and part of the rewards mined by the miners will be locked. The penalty mechanism has also been changed accordingly. Only when the task of file hosting is completed can the mining reward be unlocked. If miners want to profit, they need to have strong computing power and be able to provide stable storage services for a long time.
If this is acceptable to miners, the recent "pre-mortgage" mechanism has left miners at a loss.
"Pre-mortgage" is proposed in the latest Calibration version of Filecoin, which means that every sector encapsulated requires a certain amount of FIL to be pledged in advance, and the pledged token needs to be locked for 180 days and then released in 180 days.
The consequence of "pre-mortgage" is that FIL token has worse liquidity in the early stage.
A large number of FIL mortgages are required in the early stage, which will force miners to find the official to buy coins, and the long lock-up period causes most miners to choose to sell coins instead of encapsulation. "The miners have put their money in the hardware, where can they go out and buy coins?"
Since there is not enough funds to buy coins as collateral, it loses the qualification for mining. Even if the mortgage funds are saved, it is almost impossible to pay back with the small amount of currency in the early period.
Sun Ming said: "The mining output is too small, making it difficult for early miners to maintain operations."
The adjustment of the economic model continues to compress the income of early miners, and the voice of miners proposing to fork Filecoin is also getting louder.
Sun Ming believes: "On the one hand, it is the protest of the miners against ProtocolLabs (requesting it to modify the economic model), and on the other hand, it is also the desperate fight of the miners forced to do nothing."
Li Bai posted a circle of friends to express his attitude. As shown below:

[link]1
Another very important point is that, according to the current reward mechanism, Filecoin competition in China is tantamount to "college entrance examination".
Take the Filecoin big miner test competition as an example, miners can only be rewarded if they are ranked in the top 50 in their area or in the top 100 among all miners. Looking at the situation of Chinese miners, 9 of the top 10 nodes in the world are from China. According to people familiar with the matter, about 80% of Filecoin miners are concentrated in China. The fierce competition can be imagined.
Wang Qingshui expressed his concern: more than 90% of miners may not make money. Many miners saw that they couldn't make money, and they had the idea of opening up Filecoin "other tracks". Therefore, the call for a Filecoin fork is the strongest in China.
Unaffordable mining costs and thresholds
In addition to Filecoin's economic model, another point that miners complain about is Filecoin's threshold and cost.
The cost of Filecoin mining input and the technical threshold of operation are beyond the reach of many miners and mines.
Filecoin has a severe punishment mechanism, which can ensure the safety of the data party, but at the same time it will bring a high threshold for mining professionalism and operation and maintenance stability.
In order to ensure uninterrupted power and no disconnection, it must be hosted in a high-level IDC computer room. In order to ensure mining efficiency, the network, computing power, and storage hardware must not be poor. Therefore, miners need to use a large sum of money to purchase high-end hardware equipment.
Instant window-POST verification and submission requires high algorithms and error repair capabilities, and requires professional algorithms and operation and maintenance teams.
In addition, the threshold for Filecoin mining may be above 10TB or even higher.
Entry mining has a threshold for storage and technical maintenance, and a lot of money is needed to purchase hardware equipment.
Earlier, a blogger did a cost calculation. With 30 mining machines as a cluster calculation, the expenditure for purchasing mining machines alone was as high as 6 million. Coupled with the cost of computer room construction, operation and maintenance, Filecoin mining costs may be more than 10 million yuan.
Wang Qingshui also mentioned the flaws: “Many ordinary miners and even servers cannot participate, which is contrary to the original intention of the project.”
Some people in the community expressed their concerns: "I have invested so much. What if something goes wrong after Filecoin goes online? Wouldn't it be a loss?"
So some miners are thinking, can they lower the threshold of mining while ensuring safety?
Some miners pointed out that not all mining machines need to be hosted in the IDC computer room, which is costly and prone to waste of resources. If it can be hosted in different computer rooms according to the performance of each type of mining machine, it can not only ensure safety, but also reduce costs.
Judging from the interview, many industry insiders are on the sidelines of the Filecoin fork.
Li Bai said: "There are many people who have ideas, but few people can put them into action."
Wang Qingshui believes that any popular big project will be forked. Are BTC and ETH forked less? But how many forks can surpass the original version?
Some miners think that the fork is just talking: "Someone will follow the official game.", "Who wrote the code for you after the fork? Do you dare to use the code you wrote?"
The Filecoin fork is "undercurrent". As the Filecoin mainnet approaches, miners' actions will become more frequent, and we will continue to report.
What do you think of the Filecoin fork? Please let us know in the comments section.

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

https://preview.redd.it/vhvj6v093df51.jpg?width=1024&format=pjpg&auto=webp&s=00c0c223d9758edec8ed49a8cb9024f96d3ee343
Greetings from the UMI Team! Our Whitepaper describes in detail the key pros and cons of the two mechanisms which the great majority of other cryptocurrencies are based on:
Proof-of-Work (PoW) — mining technology. Used in Bitcoin, Ethereum, Litecoin, Monero, etc.
Proof-of-Stake (PoS) and its derivatives — forging technology. Used in Nxt, PeerCoin, NEO, PRIZM, etc.
As a result of a careful analysis of PoW and PoS, which are designed to fight against centralization, there came a conclusion that they both fail to perform their main mission and, in the long run, they lead to the network centralization and poor performance. For this reason, we took a different approach. We use Proof-of-Authority (PoA) algorithm coupled with master nodes, which can ensure the UMI network with decentralization and maximum speed.
The Whitepaper allows you to understand the obvious things. This article will give you a clear and detailed explanation of the technology implemented in the UMI network. Let's glance at the heart of the network right now.
Proof-of-Authority: How and Why It Emerged
It's been over a decade since the first transaction in the Bitcoin network. Over this time, the blockchain technology has undergone some qualitative changes. It's down to the fact that the cryptocurrency world seeing the emerging Proof-of-Work defects in the Bitcoin network year after year has actively searched for ways to eliminate them.
PoW decentralization and reliability has an underside of low capacity and scalability problem that prevents the network from rectifying this shortcoming. Moreover, with the growing popularity of Bitcoin, greed of miners who benefit from high fees resulting from the low network throughput has become a serious problem. Miners have also started to create pools making the network more and more centralized. The “human factor” that purposefully slowed down the network and undermined its security could never be eliminated. All this essentially limits the potential for using PoW-based cryptocurrencies on a bigger scale.
Since PoW upgrade ideas came to nothing, crypto community activists have suggested cardinally new solutions and started to develop other protocols. This is how the Proof-of-Stake technology emerged. However, it proved to be excellent in theory rather than in practice. Overall, PoS-based cryptocurrencies do demonstrate a higher capacity, but the difference is not as striking. Moreover, PoS could not fully solve the scalability issue.
In the hope that it could cope with the disaster plaguing all cryptocurrencies, the community came up with brand new algorithms based on alternative operating principles. One of them is the Proof-of-Authority technology. It was meant to be an effective alternative with a high capacity and a solution to the scalability problem. The idea of using PoA in cryptocurrencies was offered by Gavin Wood — a high-profile blockchain programmer and Ethereum co-founder.
Proof-of-Authority Major Features
PoA's major difference from PoW and PoS lies in the elimination of miner or forger races. Network users do not fight for the right to be the first to create a block and receive an award, as it happens with cryptocurrencies based on other technologies. In this case blockchain's operating principle is substantially different — Proof-of-Authority uses the “reputation system” and only allows trusted nodes to create blocks.
It solves the scalability problem allowing to considerably increase capacity and handle transactions almost instantly without wasting time on unnecessary calculations made by miners and forgers. Moreover, trusted nodes must meet the strict capacity requirements. This is one the main reasons why we have selected PoA since this is the only technology allowing to fully use super-fast nodes.
Due to these features, the Proof-of-Authority algorithm is seen as one of the most effective and promising options for bringing blockchain to various business sectors. For instance, its model perfectly fits the logistics and supply chain management sectors. As an outstanding example, PoA is effectively used by the Microsoft Azure cloud platform to offer various tools for bringing blockchain solutions to businesses.
How the UMI Network Gets Rid of the Defects and Incorporates the Benefits of Proof-of-Authority Method
Any system has both drawbacks and advantages — so does PoA. According to the original PoA model, each trusted node can create a block, while it is technically impossible for ordinary users to interfere with the system operation. This makes PoA-based cryptocurrencies a lot more centralized than those based on PoW or PoS. This has always been the main reason for criticizing the PoA technology.
We understood that only a completely decentralized product could translate our vision of a "hard-to-hit", secure and transparent monetary instrument into reality. Therefore, we started with upgrading its basic operating principle in order to create a product that will incorporate all the best features while eliminating the defects. What we’ve got is a decentralized PoA method. We will try to explain at the elementary level:
- We've divided the nodes in the UMI network into two types: master nodes and validator nodes.
- Only master nodes have the right to create blocks and confirm transactions. Among master node holders there's the UMI team and their trusted partners from across the world. Moreover, we deliberately keep some of our partners — those who hold master nodes — in secret in order to secure ourselves against potential negative influence, manipulation, and threats from third parties. This way we ensure maximum coherent and reliable system operation.
- However, since the core idea behind a decentralized cryptocurrency rules out any kind of trust, the blockchain is secured to prevent master nodes from harming the network in the event of sabotage or collusion. It might happen to Bitcoin or other PoW- or PoS-based cryptocurrencies if, for example, several large mining pools unite and perform a 51% attack. But it can’t happen to UMI. First, the worst that bad faith master node holders can do is to negligibly slow down the network. But the UMI network will automatically respond to it by banning such nodes. Thus, master nodes will prevent any partner from doing intentional harm to the network. Moreover, it will not be able to do this, even if most other partners support it. Nothing — not even quantum computers — will help hackers. Read our post "UMI Blockchain Six-Level Security" for more details.
- A validator node can be launched by any participant. Validator nodes maintain the network by verifying the correctness of blocks and excluding the possibility of fakes. In doing so they increase the overall network security and help master nodes carry out their functions. More importantly, those who hold validator nodes control those who hold master nodes and confirm that the latter don't violate anything and comply with the rules. You can find more details about validator nodes in the article we mentioned above.
- Finally, the network allows all interested users to launch light nodes (SPV), which enables viewing and sending transactions without having to download the blockchain and maintain the network. With light nodes, any network user can make sure if the system is operating properly and doesn't have to download the blockchain to do this.
- In addition, we are developing the ability to protect the network in case 100% of the master nodes (10,000 master nodes in total) are "disabled" for some reason. Even this is virtually impossible, we've thought ahead and in the worst-case scenario, the system will automatically move to PoS. By doing so, it will be able to continue processing transactions. We're going to tell you about this in our next publications.
Thus, the UMI network uses an upgraded version of this technology which possesses all its advantages with drawbacks eliminated. This model is truly decentralized and maximum secured.
Another major drawback of PoA-based cryptos is no possibility to grant incentives to users. PoA doesn't imply forging or mining which allow users to earn cryptocurrency while generating new coins. No reward for maintaining the network is the main reason why the crypto community is not interested in PoA. This is, of course, unfair. With this in mind, the UMI team has found the best solution — the unique staking smart-contract. It allows you to increase the number of your coins up to 40% per month even with no mining or forging meaning the human factor cannot have a negative impact on the decentralization and network performance.
New-Generation Proof-of-Authority
The UMI network uses an upgraded version of PoA technology which possesses all its advantages with drawbacks virtually eliminated. This makes UMI a decentralized, easily scalable, and yet the most secure, productive, profitable and fair cryptocurrency, working for the sake of all people.
The widespread use of UMI can change most aspects of society in different areas, including production, commerce, logistics, and all financial arrangements. We are just beginning this journey and thrilled to have you with us. Let's change the world together!
Best regards, UMI Team!

Cryptocurrency Mining Today

Cryptocurrency Mining Today
Mining is one of the key concepts in the crypto world. Everyone who comes into contact with this sphere somehow wonders about the mining of coins. How profitable is mining in 2020, and what are the current trends?
by StealthEX
Crypto mining is a process during which a computer solves mathematical problems, resulting in the release of new blocks of information. This gives its owners a certain amount of coins, which is deposited in the total pot and registered in the public “ledger”, so-called blockchain. Machines in the network are also checking transactions with existing coins, adding this information to the blockchain as well.
As for the issue itself, the most well-known algorithm of mining is Proof-of-Work (PoW), used in the networks of Bitcoin, Litecoin, Ethereum and many others.
During the mining process, the latest transactions are verified and compiled into blocks. It is usually a series of calculations with an iteration of parameters to find a hash with the specified properties. The node which first solves this problem receives a reward. This approach was specifically designed to encourage those who provide the computing power of their mining machines to maintain the network and mine new coins.
It is usually no need for a newcomer to know and understand all the complicated details of the mining process, just how much they can earn with certain equipment and electricity costs.
Everything is designed in such a way that the complexity of calculations is steadily increasing, which then requires a constant increase in the computing power of the network. In 2009-2010, for mining bitcoin, miners only had to download and run the software on their personal computers, but very soon the network became so complicated that even with best PCs with a powerful processor, mining became unprofitable. That’s why miners started to use more effective video cards (graphics processing units or GPUs) and join them in so-called “farms”.
In most systems, the number of coins is determined in advance. Also, many networks are gradually reducing rewards for miners. Such emission restrictions were built into the algorithm to prevent inflation.
Thus, the cost of mining for smaller participants no longer pays off, which makes them turn off their hardware or switch to another coin where they can still make their profit.
In particular, on the evening of May 11, 2020, a halving took place in the bitcoin network, the reward for mining was halved, from 12.5 to 6.25 BTC. In June, the revenue of bitcoin miners decreased by 23%, to the lowest since March 2019.
However, in mid-June, the difficulty of bitcoin mining showed a record growth over the past 2.5 years. Mining the first cryptocurrency has become 15% more difficult. Although, by the beginning of July, the complexity had stabilized. The growing difficulty of mining the first cryptocurrency indicates that new miners have joined its network. Previously, some of them turned off the equipment, as it became less profitable to mine the coin due to a decrease in its cost and halving.
Now the absolute majority of new coins are generated by industrial mining. This is done by large data centers equipped with specialized computers based on the ASIC architecture. ASICs are integrated circuits that were initially optimized for a specific task, namely the mining of cryptocurrencies. They are much more productive than CPUs and video cards, and at the same time consume much less electricity. ASIC computers are the main type of equipment for the industrial production of crypto.
So now, after the halving, BTC coin mining has become even less profitable. For beginners, mining the first cryptocurrency is unlikely to be suitable. It is more often earned by large companies that have all the necessary equipment, access to cheap rental conditions, electricity and maintenance.
Hence newbies are better off starting with mining altcoins. It is even more profitable to work in a pool, that is, together with other miners. This can help to place farms in one place and negotiate a favourable price for electricity, so you can get a small but stable income dux to the total capacity of the pool.
Therefore, it has become much more difficult for regular users who have only non-specialized equipment at their disposal to generate virtual money. However, GPU developers have significantly increased the performance of their devices in recent years, so mining on a video card is still common.
Another important event that changes the situation in the mining sphere will be the hardfork of the Ethereum network with the turn to the Proof-of-Stake algorithm. For now, Ethereum is the most popular altcoin for GPU mining, but Ethereum 2.0 will not require using such powerful equipment, so then it switches to PoS, GPU owners will have to look for alternative coins to mine.
At the moment the most popular altcoins for mining on GPUs are Ethereum (ETH), Ethereum Classic (ETC), Grin (GRIN), Zcoin (XZC), Dogecoin and Ravencoin (RVN). There are actually a lot of mining programs that automatically determine which coin is more profitable to mine at the moment.
In the coming years, the market is waiting for a race of technologies. Manufacturers are investing in finding ways to increase hashing speed and reduce power consumption. Mining pools will play an increasing role. The market will also be affected by applications for mining cryptocurrencies on smartphones that require low computing power, such as Dash or Litecoin.

Foreword
The consensus mechanism is one of the important elements of the blockchain and the core rule of the normal operation of the distributed ledger. It is mainly used to solve the trust problem between people and determine who is responsible for generating new blocks and maintaining the effective unification of the system in the blockchain system. Thus, it has become an everlasting research hot topic in blockchain.

Source: Hasib Anwar, "Consensus Algorithms: The Root Of The Blockchain Technology"
The picture above shows 14 relatively mainstream consensus mechanisms summarized by a geek Hasib Anwar, including PoW (Proof of Work), PoS (Proof of Stake), DPoS (Delegated Proof of Stake), LPoS (Lease Proof of Stake), PoET ( Proof of Elapsed Time), PBFT (Practical Byzantine Fault Tolerance), SBFT (Simple Byzantine Fault Tolerance), DBFT (Delegated Byzantine Fault Tolerance), DAG (Directed Acyclic Graph), Proof-of-Activity (Proof of Activity), Proof-of- Importance (Proof of Importance), Proof-of-Capacity (Proof of Capacity), Proof-of-Burn ( Proof of Burn), Proof-of-Weight (Proof of Weight).
Next, we will mainly introduce and analyze the top ten consensus mechanisms of the current blockchain.
》DBFT
-Concept:
Delegated Byzantine fault tolerance. The improved Byzantine fault-tolerant algorithm makes it suitable for blockchain systems. The system consists of nodes, delegators (who can approve blocks), and speakers (who proposes the next block). It is a consensus algorithm that guarantees fault tolerance implemented inside the NEO blockchain.
-Principle:
In this mechanism, there are two participants: the professional bookkeeper "bookkeeping node" and the ordinary users in the system.
Ordinary users vote based on the proportion of holding stake to determine the bookkeeping node. When a consensus is required, a spokesperson is randomly selected from these bookkeeping nodes to draw up a plan, and then other bookkeeping nodes will vote basing on the Byzantine fault tolerance algorithm.That is, majority principle. If more than 66% of the nodes agree to the spokesperson’ plan, a consensus is reached; otherwise, the spokesperson is re-elected and the voting process is repeated.
-Representative application: Neo, etc.
》PoA
-Concept:
Proof of authority. That is, certified by some accredited accounts, these accredited accounts are called "validators". The software that the verifier runs that supports the verifier to place transactions in blocks.
-Principle:
Three conditions:
  1. The identity must be formally verified on the chain, and the information can be cross-verified in a publicly available domain;
  2. The qualifications must be difficult to obtain, so that the rights of the verification block obtained are precious enough;
  3. The authoritative inspection and procedures must be completely unified.
With PoA, every individual has the right to become a verifier, so there is an incentive to maintain the position of the verifier once acquired. By attaching a reputation to the identity, the verifier can be encouraged to maintain the transaction process. Because the verifier does not want to gain a negative reputation, it will lose its hard-won verifier status.
-Representative applications: VeChain, etc.
》DAG
-Concept:
Directed acyclic graph. Each newly added unit in the DAG is not only added to the long chain block, but added to all the previous blocks, verifying each new unit and confirming its parent unit and the parent unit of the parent unit, and gradually confirming until the genesis unit. As the hash of its parent unit is included in its own unit, the blockchains of all transactions are connected to each other to form a graph-like structure with time.
-Principle:
In the DAG network, each node can be a trader and a validator, because the transaction processing in DAG is done by the transaction node itself. Taking IOTA as an example, IOTA’s Tangle led
ger does not need to pay transaction fees while ensuring high-speed transaction processing. However, it does not mean that the transaction is free, because in this ledger, the initiation of each transaction needs to verify the other two random transactions first, and connect the transaction initiated by itself to these two transactions, so the responsibility that miners on the blockchain bear is distributed to all traders. The DAG method of processing transactions can be called asynchronous processing mode.
Figure 10 The difference between the traditional blockchain structure and the DAG structure

-Representative applications: IOTA, etc.
》PoET
-Concept:
Proof of elapsed time. That is, it is usually used in a permissioned blockchain network. It can determine the mining rights of the block holders in the network. The permissioned blockchain network requires any prospective participants to verify their identity before joining. According to the principles of the fair lottery system, each node is equally likely to become the winner.
-Principle:
Each participating node in the network must wait for a randomly selected period, and the first node to complete the set waiting time will get a new block. Each node in the blockchain network will generate a random waiting time and sleep for a set time. The node that wakes up first, that is, the node with the shortest waiting time, wakes up and submits a new block to the blockchain, and then broadcasts the necessary information to the entire peer-to-peer network. The same process will be repeated to find the next block.
Two factors:
  1. Participating nodes will naturally select a random time in nature, rather than deliberately;
  2. The winner did complete the waiting time.
-Representative application: HyperLedger Sawtooth, etc.
》PoSV
-Concept:
Proof of stake velocity. Proposed by Reddcoin, drawing on the concept of "money circulation speed" in economics, it mainly allocates bookkeeping rights based on the coin age of nodes participating in the competition.
-Principle:
PoSV also allocates accounting rights according to the coin age of the nodes participating in the competition, but modifies the coin age calculation formula to a function of exponential decay of growth rate. Taking Reddcoin as an example, Reddcoin sets the half-life of the coin age growth rate to 1 month. Assuming that the unit token can accumulate 1CoinDay coin age on the first day, only 0.5CoinDay coin age can be accumulated on the 31st day, and only 0.25CoinDay coin age can be accumulated on the 61st day, and so on. In this way, the nodes are encouraged to use the token to conduct a transaction after holding the token for a period of time, thereby restarting the calculation of the coin age and increasing the circulation speed of the token in the network.
-Representative applications: Reddcoin, etc.

Chapter 4 Summary of the Selection and Status Quo of Consensus Mechanism
4.1 How to choose a consensus mechanism that suits you
Step 1: Determine whether the final result is important
For some applications, the end result is very important. If you are building a new payment system that can support very small amounts, it is acceptable for the transaction result to change. Similarly, if you are creating a new distributed social network, 100% guarantee that the status is updated immediately is not particularly necessary. On the contrary, if you are creating a new distributed protocol, the final result is critical to the user experience. For example, Bitcoin has a final confirmation time of about 1 hour, Ethereum has a final confirmation time of about 6 minutes, and Tendermint Core only has a final confirmation time of 1 second.
Step 2: Determine how fast the application process needs to be
If you are building a game, is it reasonable to wait 15 seconds before each action? Due to the low block processing time of Ethereum, games built on it will cause poor user experience due to Ethereum's throughput. However, the application for the transfer of housing property rights can be run on Ethereum. Use the Cosmos SDK to build an application that allows developers to freely use Tendermint Core. It has a short block processing time and high throughput, and is capable of processing 10,000 transactions per second. You can reduce the required communication overhead and speed up the application by setting the maximum number of validators for the application.
Step 3: Determine the application's demand for decentralization
Some applications such as games may not require very high censorship resistance as a by-product of decentralization. In theory, does it really matter that the validator can create a cartel in the game and reverse the transaction result for profit? If it is not important, a blockchain such as EOS may be more suitable for your needs because of the fast transaction speed and free fees. However, some applications such as autonomous banks are more powerful and decentralized. Although Ethereum is considered to be decentralized, some supporters claim that Ethereum's mining pool is an important part of centralized platform, although there are actually only 11 validators (mining pools). One of the major benefits of building your own blockchain instead of building on a smart contract platform is that you can customize the way the application completes verification. However, it is difficult to build your own blockchain, so the Cosmos SDK is very useful, you can easily build your own blockchain and customize the degree of decentralization you need.
Step 4: Determine whether the system can be terminated
If you are building a new application similar to a distributed ride-sharing service, then ensuring 24/7 service must be the first priority, even if there are occasional errors in accounting similar to transactions. One of the properties of Tendermint Core is that if there is a disagreement between network validators, the network will suspend operations instead of proceeding erroneous transactions. Applications such as decentralized exchanges require correctness at all costs-if there is a problem, it is far better to suspend trading on the decentralized exchange than there may be trading problems.
Summary: Choose a suitable consensus algorithm after weighing the advantages and disadvantages
All in all, there is no single best consensus algorithm. Each consensus algorithm has its own value and advantages. You need to have your own judgments and choices. However, by understanding the relevant processes of the consensus mechanism, including proposals and agreements, and establishing a framework to consider the types of consensus algorithms that your application may require, you should be able to make wiser decisions.
4.2 Future development of consensus mechanism
The consensus algorithm is one of the core elements of the blockchain. Although there are more than 30 consensus mechanisms listed in the article, there are still many niche consensus mechanisms that may not be discussed. As the blockchain technology is gradually known and accepted by the public, more and more newer and better consensus algorithms may appear in the future, which may be brand-new consensus algorithms, and more should be improvement and optimization version based on the current consensus algorithm.
After 2016 and 2017 years’ fast development, the current consensus algorithm does not have a recognized evaluation standard, but is generally more biased towards fairness and decentralization, as well as some technical related issues, such as energy consumption and scalability , Fault tolerance and security, etc. However, blockchain technology must be combined with requirements and application scenarios, and the consensus mechanism algorithm and incentive mechanism are inseparable. How to customize a suitable consensus mechanism according to the characteristics of your own project and optimize the current consensus mechanism will become the future direction of consensus mechanism development
CelesOS
