Bitcoin SV

Bitcoin SV (BSV) is a public chain forked from Bitcoin Cash in 2018 that advocates restoring the original Satoshi protocol design, featuring uncapped block capacity and byte-based low-cost micropayments, with standardization and adoption pushed by the Switzerland-based non-profit BSV Association. Consensus is proof of work, the node software is SV Node, and miners compete on hashpower to produce blocks. Its narrative positions the chain as a high-throughput data ledger for enterprise and government use, emphasizing on-chain data integrity and auditability; after the 2024 UK High Court judgment in COPA v Wright found that Craig Wright is not Satoshi Nakamoto, ecosystem messaging shifted further toward pure engineering specifications.

On April 7, 2026, BSV activated the Chronicle upgrade (SV Node v1.2.0) at block height 943,816. The upgrade restores early script opcodes such as OP_VER and OP_SUBSTR, reinstating the Original Transaction Digest Algorithm, raising the consensus limit on script numbers from 750KB to 32MB and dropping malleability restrictions for transactions that opt into higher version numbers, which is viewed as completing the protocol restoration begun with Genesis in 2020. Earlier the same year, v1.1.0 reintroduced a signed alert system and added per-IP connection limits. The modular node architecture Teranode has demonstrated over one million transactions per second on testnet, against roughly 2,800 TPS on mainnet.
