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.

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.

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.
