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.

Note that we may set state.reason to NOT_STANDARD for extra soft-fork flags in flags, block-checking callers should probably reset it to CONSENSUS in such cases.

◆ CheckSequenceLocks()

bool CheckSequenceLocks ( const CTxMemPool pool,
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.

See consensus/consensus.h for flag definitions.

◆ FindFilesToPrune()

static void FindFilesToPrune ( std::set< int > &  setFilesToPrune,
uint64_t  nPruneAfterHeight 
)
static

Prune block and undo files (blk???.dat and undo???.dat) so that the disk space used is less than a user-defined target.

The user sets the target (in MB) on the command line or in config file. This will be run on startup and whenever new space is allocated in a block or undo file, staying below the target. Changing back to unpruned requires a reindex (which in this case means the blockchain must be re-downloaded.)

Pruning functions are called from FlushStateToDisk when the global fCheckForPruning flag has been set. Block and undo files are deleted in lock-step (when blk00003.dat is deleted, so is rev00003.dat.) Pruning cannot take place until the longest chain is at least a certain length (100000 on mainnet, 1000 on testnet, 1000 on regtest). Pruning will never delete a block within a defined distance (currently 288) from the active chain's tip. The block index is updated by unsetting HAVE_DATA and HAVE_UNDO for any blocks that were stored in the deleted files. A db flag records the fact that at least some block files have been pruned.

Parameters
[out]setFilesToPruneThe set of file indices that can be unlinked will be returned

◆ ProcessNewBlock()

bool ProcessNewBlock ( const CChainParams chainparams,

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.

May not be called in a validationinterface callback.

Parameters
[in]pblockThe block we want to process.
[in]fForceProcessingProcess this block even if unrequested; used for non-network block sources and whitelisted peers.
[out]fNewBlockA boolean which is set to indicate if the block was first received via this call
