Bitcoin SV Node Official EN
Four fundamental pillars form the basis of Bitcoin SV’s roadmap to create the one blockchain for the world: stability, scalability, security, and safe instant transactions (a.k.a 0-confirmation).
“The existing Visa credit card network processes about 15 million Internet purchases per day worldwide. Bitcoin can already scale much larger than that with existing hardware for a fraction of the cost. It never really hits a scale ceiling.” – Satoshi Nakamoto (April 2009)
1 – Stability
Businesses, especially the biggest enterprises, require stability before they will operate on a technology platform. Repeated, unnecessary, and unproven changes to the Bitcoin protocol can be detrimental to the economic incentive structure and security of the blockchain. They can also cause significant uncertainties for large scale businesses that need to plan years in advance and commit significant resources before deciding to build applications and projects on Bitcoin SV.
The Bitcoin SV vision is to provide assured stability with only a limited and well known set of changes planned to restore the Bitcoin protocol to its original design, and enable innovation to occur on top of a stable base protocol.
Part of this is restoring the Satoshi op_codes to enable businesses and development teams around the world to create the many solutions possible on the BSV blockchain, such as smart contracts, tokenisation, atomic swaps, and many more.
2 – Scalability
In order for Bitcoin SV to truly act as a global money platform, it is necessary to demonstrate that the platform is ready to process transaction volume at the required scale. The Bitcoin SV roadmap is primarily focussed on delivering capacity increases, through bigger default or miner configurable block sizes and performance improvements. Out of the nine test environments in use by the project, the SV Gigablock Testnet (SV-GBTN) is specifically dedicated to identifying bottlenecks and performance measurement of proposed changes. The SV-GBTN is running on a continuous cycle of performance tests and the results of those are for public consumption so that miners and other industry participants will be able to make informed scaling decisions.
By enabling massive scaling, Bitcoin SV will pave the way for the BSV blockchain to support significantly higher transaction volumes and more transaction fees for miners. This is important for miners to maintain profitability as the block reward will halve again in the year 2020 (reducing from 12 BSV to 6.25 BSV for each block), and halve again in later years.
Massive scaling is also important to convince enterprises to use BSV for their blockchain applications – which will require big blocks and large throughput capacity.
3 – Security
Bitcoin SV will be a global currency. To enable such a future, we need to be prepared to ensure a level of security commensurate with a global money system. To do this, the Bitcoin SV project has focused on rigorous Quality Assurance for mining node software.
This is achieved by implementing a rigid set of test phases with full traceability throughout the test pipeline, to assure users that changes pass through a formal and rigorous validation process before they are accepted. In this respect, Bitcoin SV aspires to levels of Quality Assurance exemplified by mission critical industries such as aerospace, medicine and national security.
First, the team will use best practice change management processes and engage external QA expertise from other security-sensitive industries to monitor and audit its QA processes.
Second, the project will engage the services of an industry-leading blockchain security audit firm.
Third, the project will offer a lucrative bug bounty program matching the likes of Google and Microsoft to motivate and mobilize security researchers around the world to find and responsibly report security vulnerabilities. The team has engaged expert service providers in the field to develop an industry best practice “Responsible Disclosure Program.”
4 – Safe instant transactions (a.k.a. 0-conf)
Instant transactions are key to unlocking the brick and mortar merchant market for Bitcoin SV payments. Security improvements can be made to better secure instant transactions for the future, and the Bitcoin SV roadmap treats safe instant transactions as a key priority.
The Bitcoin SV project assures its commitment to stringent quality with several measures.
First, the team has implemented best practice change management processes, and has engaged external QA expertise from security-sensitive industries to monitor and audit these processes. Furthermore, the Bitcoin SV project has commissioned a dedicated QA team consisting of a QA manager and three dedicated QA Engineers responsible for the development and maintenance of test environments as well as performing, documenting and approving all changes.
Second, the project has engaged the services of an industry-leading blockchain security audit firm. This outside team will serve two purposes:
1. Complete a full security audit of the Bitcoin SV code base. This audit will cover not only the code itself but also development practices and processes to assist in building the most robust node development team in the industry.
2. Provide ongoing review and threat analysis of all code changes as and when they are submitted as candidates.
Third, the Bitcoin SV project will offer a generous bug bounty program (funded by CoinGeek) to motivate and mobilize security researchers around the world to find and report security vulnerabilities. With input from expert service providers in the field, the Bitcoin SV team is developing an industry best practice “Responsible Disclosure Program.” Bounties are dependent on bug criticality with the highest severity attracting a bounty of USD $100,000 (payable in BSV).
The Responsible disclosure policy can be found here along with PGP key details.
This document was last updated on 23rd December 2019. Previous versions of the Responsible Disclosure Policy can be found here.
Security is core to our values, and we value the input of security researchers acting in good faith to help us maintain high standards of security and privacy for our users and the Bitcoin SV blockchain. This includes encouraging responsible vulnerability research and disclosure. This policy sets out our definition of good faith in the context of finding and reporting vulnerabilities, as well as what you can expect from us in return.
We may modify the terms of this policy or terminate this policy at any time. We won’t apply any changes we make to these policy terms retroactively.
