◆ ActivateBestChain()

bool ActivateBestChain	(	CValidationState &	state,
		const CChainParams &	chainparams,
		std::shared_ptr< const CBlock >	pblock
	)

Make the best chain active, in multiple steps.

Find the best known block, and make it the tip of the block chain.

The result is either failure or an activated best chain. pblock is either nullptr or a pointer to a block that is already loaded (to avoid loading it again from disk).

◆ CheckFinalTx()

bool CheckFinalTx	(	const CTransaction &	tx,

◆ CheckInputs()

bool CheckInputs	(	const CTransaction &	tx,
		CValidationState &	state,

		bool	fScriptChecks,
		unsigned int	flags,
		bool	cacheSigStore,
		bool	cacheFullScriptStore,
		PrecomputedTransactionData &	txdata,
		std::vector< CScriptCheck > *	pvChecks
	)

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

If pvChecks is not nullptr, script checks are pushed onto it instead of being performed inline. Any script checks which are not necessary (eg due to script execution cache hits) are, obviously, not pushed onto pvChecks/run.

Setting cacheSigStore/cacheFullScriptStore to false will remove elements from the corresponding cache which are matched. This is useful for checking blocks where we will likely never need the cache entry again.

Non-static (and re-declared) in src/test/txvalidationcache_tests.cpp

◆ CheckSequenceLocks()

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

Check if transaction will be BIP 68 final in the next block to be created.

Simulates calling SequenceLocks() with data from the tip of the current active chain. 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.

bool ProcessNewBlock	(	const CChainParams &	chainparams,
		const std::shared_ptr< const CBlock >	pblock,

	)

Process an incoming block.

This only returns after the best known valid block is made active. Note that it does not, however, guarantee that the specific block passed to it has been checked for validity!

If you want to possibly get feedback on whether pblock is valid, you must install a CValidationInterface (see validationinterface.h) - this will have its BlockChecked method called whenever any block completes validation.

Note that we guarantee that either the proof-of-work is valid on pblock, or (and possibly also) BlockChecked will have been called.

Call without cs_main held.

Parameters

[in]	pblock	The block we want to process.
[in]	fForceProcessing	Process this block even if unrequested; used for non-network block sources and whitelisted peers.
[out]	fNewBlock	A boolean which is set to indicate if the block was first received via this call

Returns: True if state.IsValid()

	)

Process incoming block headers.

Call without cs_main held.

Parameters

[in]	block	The block headers themselves
[out]	state	This may be set to an Error state if any error occurred processing them
[in]	chainparams	The params for the chain we want to connect to
[out]	ppindex	If set, the pointer will be set to point to the last new block index object for the given headers
