◆ sentinel_attestation

Function Documentation

◆ input_from_output() [1/2]

auto cbdc::transaction::input_from_output	(	const full_tx &	tx,
		size_t	i ) -> std::optional< input >

Calls input_from_output after calculating the TXID.

Parameters

tx	the transaction from which to read outputs
i	index of the target output

Returns: result of input_from_output(tx, i, tx_id(tx))

Definition at line 99 of file transaction.cpp.

◆ input_from_output() [2/2]

auto cbdc::transaction::input_from_output	(	const full_tx &	tx,
		size_t	i,
		const hash_t &	txid ) -> std::optional< input >

Converts the output at the specified index to an input.

Parameters

tx	the transaction from which to read outputs
i	index of the target output
txid	the txid of the transaction

Returns: resultant input, or std::nullopt if i is invalid.

◆ tx_id()

auto cbdc::transaction::tx_id ( const full_tx & tx ) -> hash_t

nodiscardnoexcept

Calculates the unique hash of a full transaction.

Returns a cryptographic hash of the inputs concatenated with the outputs (which are first transformed into inputs). Because output owners cannot reuse outputs across different transactions, this method will always generate a unique identifier for valid transactions.
