Bitcoin's network has achieved a new peak in computational power, reaching a hashrate of 1,057 exahash per second (EH/s) or 1.057 zettahash per second (ZH) on September 12, 2025. This milestone was recorded at 6 a.m. Eastern, with a slight decrease to 1,046.39 EH/s by 10 a.m. The average block interval was 9 minutes and 25 seconds, suggesting a potential difficulty increase of 6.12% by September 18. The current difficulty is at a record 136.04 trillion. This surge in hashrate highlights the network's robust security and miner confidence in Bitcoin's future. However, miners are challenged by shrinking on-chain rewards and low fee revenue, necessitating reliance on Bitcoin price increases and efficiency improvements to sustain profitability.
