Module block 

Structs

BlockValidationContext

Block validation context: time, network, fork activation, and optional rule data.

UtxoDeltaInner

Overlay delta for disk sync. Returned by connect_block_ibd when BLVM_USE_OVERLAY_DELTA=1. Node converts to SyncBatch and calls apply_sync_batch instead of sync_block_to_batch. Arc<UTXO> in additions avoids clone in apply_sync_batch hot path.

Functions

apply_transaction

ApplyTransaction (Orange Paper 5.3.2)

block_validation_context_for_connect_ibd

Forwards to BlockValidationContext::from_connect_block_ibd_args with no BIP54 activation override and no boundary timestamps. Does not invent time or headers; pass the same values you would pass to the underlying constructor.

calculate_base_script_flags_for_block_network

Convenience: base script flags from (height, network) when no context is available (e.g. mempool).

calculate_script_flags_for_block_network

Convenience: script flags from (height, network) when no context is available (e.g. mempool, bench tools).

calculate_tx_id

Calculate transaction ID using proper Bitcoin double SHA256

compute_block_tx_ids

compute_block_tx_ids_into

Compute transaction IDs for a block (extracted for reuse). Produces {Hash(tx) : tx ∈ block.transactions} for ComputeMerkleRoot input (Orange Paper 8.4.1). Public so node layer can compute once and share between collect_gaps and connect_block_ibd (#21).

compute_block_tx_ids_spec

Compute { Hash(tx) : tx ∈ block.transactions } for ComputeMerkleRoot (Orange Paper §8.4.1).

connect_block

ConnectBlock: ℬ × 𝒲* × 𝒰𝒮 × ℕ × ℋ* → {valid, invalid} × 𝒰𝒮

connect_block_ibd

ConnectBlock variant optimized for IBD that returns transaction IDs instead of undo log.

get_assume_valid_height

get_block_script_flags

Orange Paper §5.2.6: exception table wins when defined; otherwise per-tx CalculateScriptFlags.

get_block_script_verify_flags_core

Bitcoin Core GetBlockScriptFlags (validation.cpp): start from SCRIPT_VERIFY_P2SH | SCRIPT_VERIFY_WITNESS | SCRIPT_VERIFY_TAPROOT, replace with the script-flag exception entry when present, then OR buried deployments (BIP66, BIP65, CSV, BIP147-at-SegWit). Same block-level bitmask is passed to script checks for every non-coinbase transaction.

script_flag_exceptions_lookup

Consensus script-flag override for block_hash on network, if any (partial map entry).
