Invalid Coinbase Transaction

Full Nodes Reject Block With Invalid Coinbase Transaction

A miner’s block was rejected by full nodes after the miner put the coinbase transaction as 13.26 BTC instead of the predetermined 12.5 BTC. Jameson Lopp (@lopp) noted that the excessive coinbase transaction amount was likely due to a bug in the mining software the miner was using. The miner lost approximately $150,000 as a result of the rejected block.
