◆ ProcessNewBlock()

bool ProcessNewBlock	(	CValidationState &	state,
		CNode *	pfrom,
		CBlock *	pblock,
		CDiskBlockPos *	dbp = `NULL`
	)

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!

Parameters

[out]	state	This may be set to an Error state if any error occurred processing it, including during validation/connection/etc of otherwise unrelated blocks during reorganisation; or it may be set to an Invalid state if pblock is itself invalid (but this is not guaranteed even when the block is checked). If you want to possibly get feedback on whether pblock is valid, you must also install a CValidationInterface - this will have its BlockChecked method called whenever any block completes validation.
[in]	pfrom	The node which we are receiving the block from; it is added to mapBlockSource and may be penalised if the block is invalid.
[in]	pblock	The block we want to process.
[out]	dbp	If pblock is stored to disk (or already there), this will be set to its location.

Returns: True if state.IsValid()

◆ cs_main

RecursiveMutex cs_main

Global state.

Mutex to guard access to validation specific variables, such as reading or changing the chainstate.

This may also need to be locked when updating the transaction pool, e.g. on AcceptToMemoryPool. See CTxMemPool::cs comment for details.

The transaction pool has a separate lock to allow reading from it and the chainstate at the same time.
