Functions

deserialize_i64

estimate_script_units_upper_bound

get_sig_op_count

Determines the exact number of signature operations executed in a transaction input by simulating the script execution. Takes into account conditional branches and only counts signature operations that are actually executed.

get_sig_op_count_upper_bound

Calculates an upper bound of signature operations in a script without executing it. This is faster than get_sig_op_count but may overestimate the count in scripts with conditional logic.

get_zk_script_units_upper_bound

is_unspendable

Returns whether the passed public key script is unspendable, or guaranteed to fail at execution.

p2sh_sig_scanner

Counts sigops in a p2sh redeem script.
