Bitcoin SV, or ‘Satoshi’s Vision,’ is a full-node implementation of Bitcoin Cash (BCH) that forked from the BCH protocol in November 2018. BSV intends to restore the original vision set out by Satoshi Nakamoto’s Bitcoin white paper by replacing every payment system worldwide with a better user experience, cheaper merchant cost, and more robust security. Notably, BSV increased the block size from 64 MB to 128 MB in an effort to increase scalability for on-chain transactions. BSV’s roadmap consists of four pillars: stability, scalability, security, and safe instant transactions that require 0 confirmations. Supporters of the project include nChain Chief Scientist Craig Wright and CoinGeek founder Calvin Ayre.
