Module transaction_hash 

Transaction sighash / txid helpers from consensus.

Structs

Bip143PrecomputedHashes

Precomputed hash components for BIP143 sighash. These are computed once per transaction and reused for all inputs.

SighashCacheKey

Per-block sighash cache: (prevout, code_hash, sighash_byte) -> hash. Core-style. Uses hash of scriptCode instead of owned Vec to avoid allocation on insert.

SighashType

SIGHASH types for transaction signature verification
