Module bip_validation

Enums§

build_bip30_index: Build Bip30Index from an existing UTXO set (for IBD resume). Scans coinbase UTXOs and counts outputs per txid. O(n) over utxo_set.
check_bip30: BIP30: Duplicate Coinbase Prevention
check_bip34: BIP34: Block Height in Coinbase
check_bip66: BIP66: Strict DER Signature Validation
check_bip90: BIP90: Block Version Enforcement
check_bip30_network: Convenience: BIP30 check using network (builds activation table).
check_bip34_network: Convenience: BIP34 check using network.
check_bip54_coinbase: BIP54: Coinbase nLockTime and nSequence (Consensus Cleanup).
check_bip54_sigop_limit: BIP54 per-transaction sigop cap (≤ 2,500 for non-coinbase when active).
check_bip54_timewarp: BIP54 timewarp mitigation at difficulty period boundaries (Orange Paper §5.4.9).
check_bip54_tx_stripped_size: BIP54: reject non-coinbase txs with witness-stripped size exactly 64 bytes.
check_bip66_network: Convenience: BIP66 check using network (for script/signature callers).
check_bip90_network: Convenience: BIP90 check using network.
check_bip147: BIP147: NULLDUMMY Enforcement
check_bip147_network: Convenience: BIP147 check using network (Bip147Network for backward compatibility).
is_bip54_active: BIP54: Consensus Cleanup activation (constant-only).
is_bip54_active_at: BIP54: Consensus Cleanup activation (with optional override).

Bip30Index: BIP30 index: maps coinbase txid → count of unspent outputs. When count > 0, a coinbase with that txid has unspent outputs (BIP30 would reject duplicate). Uses FxHashMap for faster lookups on integer-like keys (#17).
