Enums

MiningResult

Result of mining attempt

Functions

append_witness_commitment

BIP141: coinbase wtxid is 0, so appending the OP_RETURN does not change the witness root. Empty stacks when nested is None (legacy). Prefer append_witness_commitment_from_nested when mempool witnesses are known.

append_witness_commitment_from_nested

Same as append_witness_commitment, using per-tx per-input stacks. nested[i] is the witness for txs[i]. Coinbase wtxid stays 0.

calculate_merkle_root

Calculate merkle root using proper Bitcoin Merkle tree construction

calculate_merkle_root_from_tx_ids

Build merkle tree from pre-computed leaf hashes.

check_template_weight

Weight of coinbase + selected txs (empty stacks if none stored). Uses Bitcoin MAX_BLOCK_WEIGHT (4_000_000). Not an invented pool cap.

compute_merkle_root_and_mutated

Compute merkle root and CVE-2012-2459 mutation flag without aborting on mutation. Computes merkle root from leaves with optional mutation detection — always returns a root. Callers decide policy: CheckBlock rejects mutated blocks; ConnectBlock may skip the check for already-accepted blocks.

create_block_template

Create a block template for mining

create_block_template_declared

Stage 3b slice 1: miner-declared mempool subset. Resolves declared_txids, builds the Stage 3a template, and errors if the selected non-coinbase txids are not exactly that list (no silent skip). Empty declared_txids is coinbase-only. Spec-locked builders are unchanged. Overweight uses Bitcoin MAX_BLOCK_WEIGHT (not a pool-invented cap).

create_block_template_with_outputs

Same as create_block_template, then replace the coinbase and merkle root.

create_coinbase_with_outputs

Multi-output coinbase. Callers set values (subsidy + fees). Empty list is an error. Witness commitment is appended by create_block_template_with_outputs / Stratum.

create_new_block

CreateNewBlock: 𝒰𝒮 × 𝒯𝒳* → ℬ

create_new_block_with_time

CreateNewBlock variant that accepts an explicit block_time.

fit_payouts_to_reward

If payouts exceed subsidy+fees, error. Shortfall is added to the first output.

mine_block

MineBlock: ℬ × ℕ → ℬ × {success, failure}

resolve_declared_txs

Resolve named txids from a mempool list, in declaration order. Unknown or duplicate txids are errors. An empty list is allowed (coinbase-only).

sum_selected_fees

Fees of selected (non-coinbase) txs. Missing UTXOs count as 0 so empty-set tests still run.

template_block_version

Minimum header version check_bip90 accepts at height.
