bitcoin hashes are fixed-size cryptographic outputs that uniquely represent transaction data. They ensure integrity, enable block linking, and secure proof-of-work by making alterations computationally infeasible.
bitcoin hash: a fixed-length cryptographic digest produced by SHA-256 that uniquely represents transaction or block data. It ensures integrity, links blocks, and enables proof-of-work security.
A bitcoin hash is a fixed-length cryptographic output derived from transaction data and block headers; miners compute hashes to secure the network, verify blocks, and meet proof-of-work difficulty targets.
