Bitcoin miners pushed the network’s seven-day average hashrate back above 1 zettahash per second (ZH/s) for the first time since March 3, according to the source. Records dated Oct. 25, 2026, put the hashrate at 1.08023 ZH/s, still below earlier peaks of about 1.3 to 1.44 ZH/s.
The source says more efficient equipment and smaller operators appear to be helping sustain mining power as several major firms shift resources toward AI. Miners still face tighter margins: hashprice fell from $40.42 per petahash per second per day on Sept. 25, 2026, to $36.04, while mining difficulty rose 5.92% at the latest adjustment. Another difficulty increase was forecast for Oct. 29, not yet reported as completed.
