00000000000001fb5262fee5a4b0e93f1274226980cc0893dcaa9dd9e1187f95
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.
