Class

Transaction

A Bitcoin transaction — the consensus-layer value type that moves coins from one set of scriptPubKeys to another.

Overview

Construct from network/disk bytes via init(_:) for stand-alone parsing, or obtain from a Block via transaction(at:). The kernel parses, structurally validates, and produces an opaque handle; full consensus validation (witness checks, signature verification, script execution) happens through script verification APIs and processBlock(_:).

Wraps the opaque btck_Transaction type; deinit calls btck_transaction_destroy when the last Swift reference drops.

Initializers

init(Data) throws
Creates a transaction from serialized (consensus-encoded) data.

Instance Properties

var data: Data
The consensus-serialized transaction bytes — the round-trip of init(_:). Always succeeds for a valid transaction; serialization failures indicate a kernel bug.
var inputCount: Int
The number of inputs in this transaction — the previous-outputs being spent. 0 for a coinbase transaction; otherwise ≥ 1.
var outputCount: Int
The number of outputs in this transaction — the destinations and amounts being paid. Always ≥ 1.
var txid: Txid
The transaction ID — double-SHA256 of the transaction’s non-witness bytes. Returns an owned copy that outlives this transaction.
