Bitcoin SV

Bitcoin Satoshi's Vision (BSV) is the result of a perennial debate within certain cryptocurrency circles about what Satoshi Nakamoto's vision for Bitcoin was and if Bitcoin is or should strictly adhere to their vision. BSV's ethos is to "restore what was the original Bitcoin protocol." The decision to hard fork from Bitcoin Cash was a result of a dispute over canonical transaction ordering which would enable the graphene algorithm to run more efficiently and script enhancements enabling oracle data to be imported to the blockchain. In opposition, Bitcoin SV rejected these proposals and instead planned to increase the block limit to 128MB (later increased to 512MB in a hard fork) and restore certain opcodes from the original Bitcoin 0.1.0 protocol implementation. Although increased block capacity could increase transaction throughput on-chain, it could potentially restrict the universe of participants who could be capable of running full nodes, thus making this something the community needs to address in order to be able to execute on its vision of a decentralized peer-to-peer cash system.

On November 15, 2018, Bitcoin Cash split into two with the Bitcoin ABC faction, the leading Bitcoin Cash client, ultimately winning the majority of the networks hashrate and retaining the name Bitcoin Cash. Bitcoin SV is led by nChain, a research and development technology firm building tools, protocols, and applications to support blockchain growth worldwide.
