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.
