Why it is invalid
- rule and Core reject
- bad-cb-amount
- Core check
ConnectBlock- CI checks
- A complete block extending the block a public API reports at the previous height, whose coinbase pays strictly more than the mainnet subsidy at that height plus fees calculated from authenticated previous transactions. A coinbase-only body has no fees to fetch.
Incident note: 197438 - Eligius coinbase overpayment (2012)
The 1890-byte body holds the coinbase and one ordinary transaction.
The coinbase pays 5001000000 satoshis against the 5000000000 subsidy.
The transaction spends output 1 of 8d86cbc5bf98ae815b9f360d0ac208109a75ab7988fc33276fe1eebe46e7fd8f, confirmed at canonical 197333 and worth 503413843 satoshis, and pays out exactly that, so the fee is zero and the excess is 1000000 satoshis (0.01 BTC).
The block predates BIP34, so the height is bound by the canonical parent at 197437, 000000000000008cb385de6a68aaaaa6c3974b98cf8f544b8cce0db1855256c4, not by a coinbase prefix; the coinbase tag is Eligius.
