Bitcoin SV- SATOSHI VISION (BSV) Bitcoin Cash Hard Fork

  • The nature of Bitcoin is such that once version 0.1 was released, the core design was set in stone for the rest of its lifetime.”

    – Satoshi Nakamoto

    What is Bitcoin Cash?

    Bitcoin Cash is an experimental digital currency that enables instant payments to anyone, anywhere in the world. It uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Cash is a descendant of Bitcoin. It became a separate currency from the version supported by Bitcoin Core when the two split on August 1, 2017. Bitcoin Cash and the Bitcoin Core version of Bitcoin share the same transaction history up until the split.

    What is Bitcoin SV?

    Bitcoin Satoshi Vision (SV) is the name of open-source software which enables the use of Bitcoin Cash.

    The source code was originally based on the Bitcoin ABC software project.

    Bitcoin SV is a full-node implementation for Bitcoin Cash (BCH) and will maintain the vision of Bitcoin set out by Satoshi Nakamoto’s white paper in 2008: Bitcoin: A Peer-to-Peer Electronic Cash System

    Reflecting its mission to fulfil the vision of Bitcoin, the project name represents the “Satoshi Vision” or SV.   Created at the request of leading BCH mining enterprise CoinGeek and other miners, Bitcoin SV is intended to provide a clear BCH implementation choice for miners and allow businesses to build applications and websites on it reliably.

    Bitcoin SV restores the original vision to ignite the future of Bitcoin:

    • Bitcoin Cash can replace every payment system in the world with a better user experience, a cheaper merchant cost, and a safer level of security.
    • Businesses can trust the Bitcoin Cash brand to provide the stability and scale they need to commit investment and resources to use the BCH blockchain.


    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 Cash.

    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 BCH blockchain, such as smart contracts, tokenisation, atomic swaps, and many more.

    2 – Scalability

    In order for Bitcoin Cash 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 BCH 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 BCH to 6.25 BCH for each block), and halve again in later years.

    Massive scaling is also important to convince enterprises to use BCH for their blockchain applications – which will require big blocks and large throughput capacity.

    3 – Security

    Bitcoin Cash 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 Cash 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.

    Quality Program

    The Bitcoin SV project assures its commitment to stringent quality with several measures.

    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.

    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 Bitcoin Cash).


    The Bitcoin SV project begins by restoring what was the original Bitcoin
    protocol. We embrace the fact that Satoshi used script as a predicate
    to enable functionalities that go hand in hand, and beyond the function
    of cash. Re-enabled Satoshi op_codes provide the methods needed for
    smart contracts, tokenisation and other advanced technical functions to
    be done on BCH. The original protocol has what Bitcoin needs to thrive,
    and should be allowed to flourish without constant changes.

    restored, the Satoshi protocol needs to remain stable. The protocol
    should be locked down except for any critical security fixes that might
    be required. This stability will give enterprises of the world
    confidence to build their applications and projects on top of BCH. Just
    like the Internet lives on a protocol that has changed very little since
    its beginning and allows businesses to reliably plan long term projects
    on the platform, the Bitcoin Cash blockchain will provide the same

    The next key pillar is to ignite massive scalability
    on the BCH blockchain according to future market needs, rather than just
    viewing current payment transaction volume. Potential demand is a
    function of supply (among other things) and we intend to provide the
    capacity for BCH to act as the foundation for the entire financial world
    and many other industries. Major enterprises want to know the
    blockchain has sufficient scale for their projects before they commit
    significant resources and time to build on BCH. Miners needs massive
    scaling to earn more money from transaction fees in order to offset the
    block reward halving over time. Therefore, block-size limits need to be
    many magnitudes bigger than current throughput demand and ultimately
    allow for unlimited growth.

    Along the way, security is always
    important to Bitcoin SV’s roadmap. By making sure the necessary
    optimisations, testing and quality assurance steps are in place, we
    allow nodes to mine big blocks and scale to global market demands in a
    safe and reliable manner.

    An excellent payment experience is also
    needed. The Bitcoin SV project will work on both measurement and
    improvement of the safety of 0-conf transactions, fast transaction
    propagation, and miner-configurable fee policies.

    Development Team

    The Bitcoin SV team has been assembled with a view to realizing industry
    best practices, in order to deliver and maintain a full-node
    implementation with an unprecedented commitment to quality assurance and

    The Lead Developer is Daniel Connolly, who joined
    nChain after 20 years in enterprise systems and held senior IT positions
    with various United Nations agencies. Daniel contributed anonymously to
    Bitcoin for several years, has contributed to the Electron Cash
    project, and is a primary contributor to the BitcoinJ-Cash project.

    Shadders will act as Technical Director, providing project oversight
    and liaison with sponsors and industry participants. Steve began
    contributing to Bitcoin in 2011, authoring one of the first open-source
    mining-pool engines and was one of the earliest contributors to

    In addition, the Bitcoin SV team has a pool of five
    full time C++ developers with over 95 collective years of development
    experience. An external partner is providing the services of two
    additional senior C++ developers.

    The QA team consists 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.

    Additional support and management services are provided by nChain’s Project Management office and Business Services unit.





  • Bitcoin SV Mines 64 MB Block on Bitcoin Cash, Largest Ever on a Public Blockchain

    20 November 2018 – Bitcoin SV, the new full node implementation for Bitcoin Cash (BCH) mined a 64MB block, the world’s largest ever on a public blockchain. The huge block was mined by CoinGeek Mining, during an on-going Professional Stress Test of the BCH network. Just one hour before, a 38MB block was mined, also using the Bitcoin SV implementation, by SVPool, a personal initiative of nChain’s Chief Scientist Dr. Craig Wright. That 38MB block held the record for largest block mined on a public blockchain until the 64 MB block dwarfed it.

    The BCH Professional Stress Test is designed to test the BCH blockchain’s throughput capacity. The 64 MB block came at block height 557335 and the 38 MB block came at block height 557333 on the BCH network. Powered by and organized independently of any BCH full node implementation team, the testing group also ran November 10 pre-test, in which Bitcoin SV mined five 32 MB blocks, which were then the largest ever blocks mined on a public blockchain. Bitcoin SV thus continues to demonstrate its record-setting capabilities, with larger blocks now mined of 64 and 38 MB.

    Bitcoin SV is currently in the midst of a “hash war” with Bitcoin ABC to be the leading BCH implementation, with miner votes that began with the November 15 BCH network upgrade. Although Bitcoin ABC has taken an early lead, its support relies heavily upon “rented” hash borrowed by its backers ( and Bitmain Technologies) from miners on the rival Bitcoin Core (BTC) network ; in contrast, the hash backing Bitcoin SV is sustained Proof of Work from miners committed to support the BCH network on an on-going basis and which should count as legitimate votes for the “Nakamoto consensus” that determines protocol rules according to the original Bitcoin white paper.

    The Professional Stress Test results confirmed that Bitcoin SV is correct about its scaling roadmap: the BCH blockchain can handle much larger blocks and quickly scale for big enterprise use. Named for the “Satoshi Vision” of Bitcoin’s creator Satoshi Nakamoto, Bitcoin SV intends to restore the original Bitcoin protocol, keep it stable, and allow it to massively scale to a global network used by billions of people. For the recent November 15 protocol upgrade, Bitcoin SV lifted its default maximum block size to 128MB from the prior 32MB; that opened the door to the record-breaking 64MB and 38MB blocks. In contrast, Bitcoin ABC has kept its default block cap at 32MB, and is taking a slower scaling approach.

    Bitcoin SV’s lead developer Daniel Connolly remarks:

    “This is the next in a series of record-breaking blocks mined by Bitcoin SV. I believe we will see even bigger blocks reaching closer to our new 128MB default limit, especially when we eventually lift the default block cap altogether so miners can configure their own limits. The Satoshi Vision requires massive blocks, so businesses can do more complex transaction types and miners can earn more transaction fees.”

    Bitcoin SV Technical Director Steve Shadders adds:

    “For Bitcoin to achieve the Satoshi Vision, major businesses need confidence to build on a blockchain that has block capacity to support enterprise-level applications and projects, not just transactions between individual users. By locking down the protocol we can focus all our attention on scaling solutions that are needed to demonstrate that Bitcoin is ready for serious investment. That is what

    distinguishes Bitcoin SV from the other implementations, and is exactly why miners and businesses should choose Bitcoin SV over Bitcoin ABC to unlock Bitcoin’s massive potential.”

    The Bitcoin SV project was created at the request of and sponsored by Antiguan-based CoinGeek Mining, with development work initiated by nChain. The project is owned by the Antiguan-based bComm Association on behalf of the global BCH community, and the Bitcoin SV code is made available under the open source MIT license.

  • User guide to managing BCH coin splitting


    On November 15, 2018, the Bitcoin Cash (BCH( blockchain underwent a contentious hard fork with two competing rule sets: (1) one path championed by Bitcoin ABC that began a path to radically alter the original Bitcoin protocol designed by Satoshi Nakamoto; and (2) one championed by Bitcoin SV (Satoshi Vision) which sought to preserve the original Satoshi protocol and return Bitcoin closer to its original state. In subsequent days, Bitcoin ABC unilaterally introduced further consensus changes that introduced vulnerabilities to the BCH network, and abandoned the fundamental principle of Proof of Work as the security model of Bitcoin. The end result of these events is that Bitcoin Cash has now split into two persistent chains: Bitcoin SV (ticker: BSV) and Bitcoin Cash (ticker: BCH). Bitcoin SV no longer recognises BCH as Bitcoin. However, users who held BCH prior to the hard fork on November 15,, 2018 now have coins on both chains. For the stability of the markets, such users must be given effective means to deal with those coins safely.

    Transaction replay

    Given that neither side of the hard fork introduced transaction repay protection, it is now possible that when sending a transaction of BSV, the same transaction can be validly replayed on BCH. This may not be the desired result and can cause confusion to users. In order to prevent this behaviour, the coins must somehow be separated. There are several techniques for doing so with various levels of complexity.

    Long term

    If you have no need to transact your coins in the near future, the best option is to wait and conduct no transactions now. A consensus level fix to this problem will be implemented in due course. As Bitcoin ABC has consistently refused to do so either unilaterally or mutually with Bitcoin SV, the Bitcoin SV project team has made the decision to do so itself in order to promote stability for users and economic participants on both blockchains. A consensus level fix is being developed that will prevent this being issue for users of either chain. However, to minimise disruption, it must be widely supported by wallets, exchanges and other economic actors in the Bitcoin ecosystem. We will announce a timeline for this fix once an adequate level of ecosystem readiness is apparent. This is unlikely to be before the New Year 2019. However, once implemented, there will be no further need for user action other than a wallet upgrade.

    Short term

    If you wish to transact with your coins before this ecosystem wide fix is implemented, you will need to split your current BCH coins. There are several mechanisms to do. However, it is first recommended that you create a new wallet for each chain to hold your separated coins. Wallets known to support BSV are listed on the BSV implementation website:

    Exchange support

    Several exchanges will perform the coin-splitting function for you. However, in selecting an exchange, it is important to first check that it actually does offer this service. Some exchanges have stated that if unsplit coins are sent to them, they make no guarantees that you will get access to both coins. Once deposited, you can either sell one or both coins or simply withdraw them into separate wallets. Exchanges that have openly stated they support splitting of BCH coins sent to their wallets include:

    Caution: Do not assume that because an exchange has trading pairs for BSV (or BCH-SV) and BCH that it is guaranteed to support coin splitting. It is recommended you contact the exchange to confirm this before sending any coins, or send a very small amount first as a test. We will update the above exchange list as we confirm support for coin splitting behaviour with more exchanges.

    Coin splitting tools

    There are several coin splitting tools currently available. However, we cannot recommend any of them at this stage. Running coin splitting software gives that software access to your coins and without a high level of assurance that the software is not malicious, there is always the risk of coin theft.

    The Bitcoin SV team is developing its own endorsed coin-splitting tool, which will be released and announced on as soon as possible. Additionally we will be reviewing existing tools and providing a list those we consider safe.

    Further methods will be available soon

    In addition to the above, the Bitcoin SV team will be providing additional well-tested mechanisms in the near future, including a wallet customised to automatically coin split. These tools will also be announced on as soon as they are ready. Meanwhile, we urge caution as the uncertain environment creates many opportunities for fraudulent services to take advantage of user confusion. The official Bitcoin SV website will not recommend any service or software for this purpose unless we have thoroughly tested and reviewed it ourselves. We will also provide best practice procedures for using any coin-splitting services or software.

    BSV-powered Passports – New Visions for Bitcoin from Dr. Craig S. Wright

    nChain’s Chief Scientist Dr. Craig S. Wright has continued with his weekly series on his Medium account, revealing new applications and uses for Bitcoin (possible exclusively on Bitcoin SV, because they use nChain intellectual property).  In the powerful series, Wright shares his ideas about and expertise on new ground-breaking applications and services—made possible on the Bitcoin SV blockchain.

    Wright’s second entrySmart-card-based mobile wallets,” and focuses on the use of electronic cards (“smart cards”) to facilitate secure, feasible, yet user-friendly system authentication through a Bitcoin (SV) wallet. The application is an enhanced application of nChain’s patent innovation for “Security through a Personal Device and Determined Common Secret,” which through the use of a biometric (think fingerprints) smart card allows for greater ease of use and security in passports / personal identification cards, communication channels, payments, or file encryption.

    Businesses and institutions offering identification services can save costs by gaining in reliability, security, and speed.

    New possibilities are becoming feasible because of the efficient and secure database that Bitcoin SV provides; and the integrated use of BSV transactions allows direct and efficientmonetisation.

    The technology can be implemented in a smart card, but also a smart watch, or even as a direct integration into one’s passport.
