	)

Check transaction inputs, and make sure any pay-to-script-hash transactions are evaluating IsStandard scripts.

Why bother? To avoid denial-of-service attacks; an attacker can submit a standard HASH... OP_EQUAL transaction, which will get accepted into blocks. The redemption script can be anything; an attacker could use a very expensive-to-check-upon-redemption script like: DUP CHECKSIG DROP ... repeated 100 times... OP_1 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.

◆ ProcessNewBlock()

bool ProcessNewBlock	(	const std::shared_ptr< const CBlock > &	pblock,
		const FlatFilePos *	dbp

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.

Parameters

[in]	pblock	The block we want to process.
[out]	dbp	The already known disk position of pblock, or nullptr if not yet stored.

Returns: True if state.IsValid()
