Class

Txid

A 32-byte transaction identifier — double-SHA256 of a transaction’s non-witness serialization.

final class Txid

Overview

TXID (this type) is stable across witness malleation and is what prevout.hash fields reference. WTXID (not exposed on this type) additionally includes witness data. Like block hashes, TXIDs are stored internally in kernel byte order — reverse for the display-order hex used by block explorers.

Obtained via txid or txid; there is no public create initializer.

Wraps the opaque btck_Txid type; deinit calls btck_txid_destroy when the last Swift reference drops.

Instance Properties

var data: Data
The raw 32-byte TXID in internal (kernel) byte order. Reverse the byte order before hex-encoding for display in a block explorer.

Instance Methods

func equals(Txid) -> Bool
Whether two TXIDs are byte-for-byte equal. Delegates to the kernel’s btck_txid_equals for the canonical comparison.
