◆ CheckFinalTx()

bool CheckFinalTx	(	const CBlockIndex *	active_chain_tip,
		const CTransaction &	tx,
		int	flags = `-1`
	)

Transaction validation functions.

Check if transaction will be final in the next block to be created.

Calls IsFinalTx() with current block height and appropriate block time.

See consensus/consensus.h for flag definitions.

◆ CheckSequenceLocks()

bool CheckSequenceLocks	(	CBlockIndex *	tip,
		const CCoinsView &	coins_view,
		const CTransaction &	tx,
		int	flags,
		LockPoints *	lp = `nullptr`,
		bool	useExistingLockPoints = `false`
	)

Check if transaction will be BIP68 final in the next block to be created on top of tip.

Parameters

[in]	tip	Chain tip to check tx sequence locks against. For example, the tip of the current active chain.
[in]	coins_view	Any CCoinsView that provides access to the relevant coins for checking sequence locks. For example, it can be a CCoinsViewCache that isn't connected to anything but contains all the relevant coins, or a CCoinsViewMemPool that is connected to the mempool and chainstate UTXO set. In the latter case, the caller is responsible for holding the appropriate locks to ensure that calls to GetCoin() return correct coins. Simulates calling SequenceLocks() with data from the tip passed in. Optionally stores in LockPoints the resulting height and time calculated and the hash of the block needed for calculation or skips the calculation and uses the LockPoints passed in for evaluation. The LockPoints should not be considered valid if CheckSequenceLocks returns false.

		const Package &	txns,
		bool	test_accept
	)

Atomically test acceptance of a package.

If the package only contains one tx, package rules still apply. Package validation does not allow BIP125 replacements, so the transaction(s) cannot spend the same inputs as any transaction in the mempool.

Parameters

[in] txns Group of transactions which may be independent or contain parent-child dependencies. The transactions must not conflict with each other, i.e., must not spend the same inputs. If any dependencies exist, parents must appear before children.

Returns: a PackageMempoolAcceptResult which includes a MempoolAcceptResult for each transaction. If a transaction fails, validation will exit early and some results may be missing.
