Class

Coin

A UTXO — an unspent transaction output enriched with the metadata the kernel needs to validate a spending transaction.

final class Coin

Overview

A Coin carries the TransactionOutput (amount + scriptPubKey) plus two consensus-relevant metadata fields: the block height at which the creating transaction was confirmed, and whether that transaction was a coinbase (which gates the 100-block maturity rule).

Wraps the opaque btck_Coin type; deinit calls btck_coin_destroy when the last Swift reference drops.
