Bitcoin hashrate climbs to 1,000 EH/s, mining difficulty hits all time high

The Bitcoin network’s computing power has rebounded sharply, surpassing the decline seen earlier this year and reentering an upward trend. As of October 22, 2026, on-chain data from CryptoQuant shows the True Hashrate of the network has reached 1,000 exahashes per second (EH/s), or 1 zettahash per second (ZH/s), moving close to the record highs observed in late 2025. CryptoQuant founder Ki Young Ju noted that Bitcoin’s hashrate has returned to growth, with mining operations now running at full capacity across the sector. He underlined a significant transformation, as mining evolves from a venture-driven activity into a major industrial field increasingly controlled by large corporate interests. This surge in processing power has driven Bitcoin’s mining difficulty to an unprecedented level.
