@ BLOCK_CHECKPOINT
the block failed to meet one of our checkpoints
@ BLOCK_RECENT_CONSENSUS_CHANGE
Invalid by a change to consensus rules more recent than SegWit.
@ BLOCK_HEADER_LOW_WORK
the block header may be on a too-little-work chain
@ BLOCK_INVALID_HEADER
invalid proof of work or time too old
@ BLOCK_CACHED_INVALID
this block was cached as being invalid and we didn't store the reason why
@ BLOCK_CONSENSUS
invalid by consensus rules (excluding any below reasons)
@ 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_MUTATED
the block's data didn't match the data committed to by the PoW
@ BLOCK_TIME_FUTURE
block timestamp was > 2 hours in the future (or our clock is bad)

initial value. Block has not yet been rejected

@ TX_MISSING_INPUTS
transaction was missing some of its inputs
@ TX_MEMPOOL_POLICY
violated mempool's fee/size/descendant/RBF/etc limits

transaction spends a coinbase too early, or violates locktime/sequence locks
@ TX_INPUTS_NOT_STANDARD
inputs (covered by txid) failed policy rules

Invalid by a change to consensus rules more recent than SegWit.
@ TX_NOT_STANDARD
otherwise didn't meet our local policy rules
@ TX_WITNESS_MUTATED
Transaction might have a witness prior to SegWit activation, or witness may have been malleated (whic...
