Bitcoin SV

Bitcoin SV (BSV) is a blockchain that began in 2018 as a hard fork of Bitcoin Cash, which had itself split from the BTC chain a year earlier. The project states that it aims to follow the original Bitcoin protocol design described in Satoshi Nakamoto's white paper and early client software.

The protocol removed the artificial block size limit and re-enabled Script commands that had been disabled or restricted on the BTC chain. It sets no maximum block size, so capacity can grow as demand does. Its developers report blocks as large as 4 GB and more than 50 million transactions processed in a single day. A single script can hold up to 4.2 GB of data.

Teranode is a modular, microservice-based node architecture in development for the network. It has reached over 1 million transactions per second on a testnet. The design uses a UTXO model, which allows transactions to be processed in parallel. Simplified Payment Verification, as outlined in the white paper, lets users transact without storing the full blockchain history.

Its stated priorities include protocol stability, meaning the base rules are meant to stay fixed. The network supports tokens, smart contracts, low-fee micropayments and other data uses.
