Invalid block 225430
000000000000017c4a0a7be4244a3b2c0dd41f884586ad8de78356a0994e8960
Why it is invalid
- rule
- bip34_v2_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. Header version must be at least 2 and height below 227931. Applicability of the historical rolling-version threshold still requires review.
