Bitcoin Cash (BCH)
A proof-of-work cryptocurrency that split from Bitcoin in 2017 and follows a separate on-chain scaling and CashVM roadmap.
- Acronym
- BCH
- Also known as
- BCH
Bitcoin Cash (BCH) is a separate cryptocurrency and consensus network created by the August 2017 Bitcoin chain split. It inherited transaction history up to the split, then adopted distinct rules, software, market value, and infrastructure.
BCH uses SHA-256 proof of work, a UTXO ledger, CashAddr payment encoding, and a roughly ten-minute target block interval. Later upgrades added ASERT difficulty adjustment, adaptive block capacity, native transaction introspection, CashTokens, and additional CashVM operations.
BCH prioritizes more base-layer transaction capacity and regular coordinated hard-fork upgrades. That can provide spare blockspace and faster protocol iteration while increasing node-resource, implementation, and upgrade-coordination requirements.
BCH is not interchangeable with BTC or similarly named assets. Verify the network, address format, wallet support, confirmation status, and token category before transferring value.
