Coin Metrics researchers published a groundbreaking study on June 13, unveiling an innovative nonce analysis methodology for bitcoin mining. This research enables experts to dissect and identify the specific mining rigs responsible for contributing hashrate to the network, while also evaluating the energy consumption and effectiveness of these machines. Intriguingly, the data reveals that Bitmain has exerted its dominance over the industry for an extended period, with three primary Antminer models now commanding the majority of today’s hashrate.
