Block

Class

Block

A Bitcoin block — an 80-byte BlockHeader plus its list of Transaction values, structurally validated by the kernel on construction.

final class Block

Overview

Construct from consensus-serialized bytes (network or disk format) via init(_:). The kernel parses, sanity-checks structure, and produces an opaque handle; downstream consensus validation happens through processBlock(_:).

Wraps the opaque btck_Block type; deinit calls btck_block_destroy when the last Swift reference drops.

Topics

Initializers

init(Data) throws
Parses a block from its consensus-serialized bytes.

Instance Properties

var data: Data
The consensus-serialized block bytes — the round-trip of init(_:).
var hash: BlockHash
The block’s hash — double-SHA256 of the 80-byte header.
var header: BlockHeader
The 80-byte BlockHeader carrying version, previous-block hash, merkle root, timestamp, nBits, and nonce. Returns an owned copy that outlives this block.
var transactionCount: Int
The number of transactions in this block. Always ≥ 1 — every valid block carries at least a coinbase.

Instance Methods

func transaction(at: Int) -> Transaction
Returns the transaction at the given index as an owned Transaction (safe to store past this block’s lifetime).
