000000000000000009c55c7e380b7600a2966de1b79230c74212d9c45a91a50b
Why it is invalid
- rule
- bip34_coinbase_height_mismatch
- Core reject
bad-cb-height- Core check
ContextualCheckBlock- CI checks
- Both coinbase context fields, decoded height matching the scriptSig, and a scriptSig that lacks the exact expected BIP34 prefix, at height 227931 or later. A non-minimal encoding of the right number also fails the prefix check.
