Bitcoin Hashrate Sustains 1 Zetahash for First Time

Bitcoin’s mining network has surpassed a sustained hashrate of 1 zetahash per second (ZH/s), according to data from Luxor’s Hashrate Index. The milestone marks the first time the world’s largest blockchain has operated at this level for more than brief intraday periods.

The network hashrate measures the combined computational power used by miners to validate transactions and secure the blockchain. It has climbed from under 800 exahashes per second (EH/s) in January 2025 to above 1 ZH/s in September, reflecting rapid deployment of new mining hardware.

Roughly 30% of the hashrate now comes from U.S.-listed mining companies, data shows, underscoring the increasing concentration of industrial-scale operations in North America.

Bitcoin’s daily hashrate has touched 1 ZH/s several times this year, but the seven-day moving average — a metric used to smooth out short-term swings — shows this is the first period where the level has been maintained.

The growth represents a thousandfold increase in network capacity since 2016, when Bitcoin first reached 1 EH/s. Rising hashrate strengthens network security by making it more expensive to alter the blockchain. At the same time, competition among miners increases, intensifying the need for lower-cost electricity and more efficient hardware to remain profitable.

Crossing the zetahash threshold reflects the industrial scale of modern Bitcoin mining. Publicly listed companies in the U.S. now contribute about 30% of the total network power, while large-scale operations in regions such as Kazakhstan and the Middle East continue to expand capacity.
