The miner confirmed the mining of the invalid block on social media platform X (formerly Twitter), citing a bug during an experiment. “We utilize a small portion of our hash rate to experiment with our development pool and research potential methods to optimize our operations,” Marathon said. “The error was the result of an unanticipated bug that came from one of our experiments,” the company added.
