Marathon Digital mined an invalid #Bitcoin block on Wednesday, causing the firm to miss out on newly minted BTC it would have otherwise earned. An invalid block is one that violates #Bitcoin’s consensus rules, and is therefore rejected by network nodes. Marathon did not specify how its block was invalid, though some onlookers attributed the problem to a transaction ordering issue.
