◆ BlockValidationResult

strong

A "reason" why a block was invalid, suitable for determining whether the provider of the block should be banned/ignored/disconnected/etc.

These are much more granular than the rejection codes, which may be more useful for some other use-cases.

Enumerator
BLOCK_RESULT_UNSET	initial value. Block has not yet been rejected
BLOCK_CONSENSUS	invalid by consensus rules (excluding any below reasons)
BLOCK_CACHED_INVALID	this block was cached as being invalid and we didn't store the reason why
BLOCK_INVALID_HEADER	invalid proof of work or time too old
BLOCK_MUTATED	the block's data didn't match the data committed to by the PoW
BLOCK_MISSING_PREV	We don't have the previous block the checked one is built on.
BLOCK_INVALID_PREV	A block this one builds on is invalid.
BLOCK_TIME_FUTURE	block timestamp was > 2 hours in the future (or our clock is bad)
BLOCK_CHECKPOINT	the block failed to meet one of our checkpoints
BLOCK_HEADER_LOW_WORK	the block header may be on a too-little-work chain

strong

A "reason" why a transaction was invalid, suitable for determining whether the provider of the transaction should be banned/ignored/disconnected/etc.

Enumerator
TX_RESULT_UNSET	initial value. Tx has not yet been rejected
TX_CONSENSUS	invalid by consensus rules
TX_INPUTS_NOT_STANDARD	inputs failed policy rules
TX_NOT_STANDARD	otherwise didn't meet our local policy rules
TX_MISSING_INPUTS	transaction was missing some of its inputs
TX_PREMATURE_SPEND	transaction spends a coinbase too early, or violates locktime/sequence locks
TX_DUPLICATE	Tx already in mempool or in the chain.
TX_CONFLICT	Tx conflicts with another mempool tx, i.e. spends the same coin.
TX_CHILD_BEFORE_PARENT	This tx outputs are already spent in the mempool. This should never happen and is a symptom of a mempool bug/corruption.
TX_MEMPOOL_POLICY	violated mempool's fee/size/descendant/etc limits
TX_NO_MEMPOOL	this node does not have a mempool so can't validate the transaction
