943 EH/s and growing: Bitcoin mining power approaches historical threshold
Following the consolidation of Bitcoin prices, which reached an all-time high (ATH), the network's computing power reached an unprecedented level of 943 exahashes per second (EH/s).
Bitcoin Approaches Zettahash Mark
Bitcoin’s global hashrate has set a new record, peaking at 943 EH/s based on a seven-day simple moving average (SMA). The milestone was reached on May 31, just 22 days after the previous record of 929 EH/s, representing an increase of 14 EH/s from the previous peak in computing power.

What’s more, that mark is just 57 exahashes shy of the 1 zettahash per second (ZH/s) threshold. That’s a huge influx of computing power. While the hashrate has dropped slightly since June 1, it remains impressive — reaching 934 quintillion hashes per second recorded on the Bitcoin blockchain as I write this at 5:02 p.m. ET on Sunday.
In the past, some have argued that this makes the network the most powerful computing system on the planet, but direct comparisons to supercomputers are inherently challenging. Bitcoin hashing is based on integer operations, while supercomputers are measured in floating-point operations per second (FLOPS), a fundamentally different metric.
However, previous rough calculations have shown that Bitcoin’s hashrate can perform significantly more operations per second than the world’s best machines, such as El Capitan’s 1,742 exaflops — but any such side-by-side comparison is inherently limited given the different tasks. It’s like comparing poetry to mathematics, two fields without a common metric.
However, Bitcoin's computing power is distributed around the world and operates non-stop — 24 hours a day, seven days a week. While hardware failures or outages can temporarily reduce the network's computing power, this did not happen in 2025; instead, miners continually added more computing power to the system.
The latest gain comes as revenue per petahash has fallen 7.93% since May 29. At the time, the projected revenue per petahash per second (PH/s) of hash power was $56.99; today, that figure has fallen to $52.47. As the Bitcoin network approaches the zettahash frontier, the inexorable expansion of its computing power is a sign of both miner confidence and technical ambition.
Despite the fluctuations in profitability, the steady growth in computing power suggests a deeper story — one where efficiency improves year over year. Despite their operational efficiency, miners operate on very tight margins and continue to depend on higher Bitcoin prices to restore the profits seen before the fourth halving last April.
