0000000000000239bfc9b6f400b5b02ab401077bdc470d082e3da34276925cc8
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.
