Detailed Description

Transaction validation functions.

Enumeration Type Documentation

◆ BuriedDeployment

enum Consensus::BuriedDeployment : int16_t

A buried deployment is one where the height of the activation has been hardcoded into the client implementation long after the consensus change has activated.

See BIP 90.

Function Documentation

◆ CheckTxInputs()

bool Consensus::CheckTxInputs	(	const CTransaction &	tx,
		TxValidationState &	state,
		const CCoinsViewCache &	inputs,
		int	nSpendHeight,
		CAmount &	txfee
	)

Check whether all inputs of this transaction are valid (no double spends and amounts) This does not modify the UTXO set.

This does not check scripts and sigs.

Parameters

[out] txfee Set to the transaction fee if successful. Preconditions: tx.IsCoinBase() is false.
