Invalid block 225015
000000000000015437122b60d0a1d2ed7e1f98b5b292e886d6ca62042bba2035
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.
