Yesterday, Bitcoin’s total hashrate ran hot, topping out at 986 exahashes per second (EH/s); since then, it has leapt into the 1 zettahash range (ZH/s). If that computational might holds, the zettahash era could become a normal fixture going forward.
Zettahash Vibes: Bitcoin Hashrate Roars to a One-Sextillion-Hash Pace
Bitcoin’s hashrate is humming at a weekend peak; presently, per the seven-day simple moving average (SMA), it sits around 998 to 1,000 exahashes per second (EH/s), roughly a single zettahash. One ZH/s equals one sextillion—the number 1,000,000,000,000,000,000,000, or a 1 followed by 21 zeros.

That figure is immense, akin to a zettabyte—one sextillion bytes of data. Another perspective: it’s comparable to all the water across Earth’s oceans, about 1.3 sextillion liters. For scale, Earth’s total volume is roughly 1.085 sextillion cubic meters, and its mass is about 5.98 sextillion metric tons. In short, miners are churning out an astonishing number of hashes and every second.

While the network hashrate could ease, particularly if difficulty climbs to the estimate due on Sept. 4, 2025, the zettahash era may soon become the norm. It’s edged closer each week, and the current pace has block intervals at 9 minutes 23 seconds, implying an expected difficulty increase of 6.43%.
Of the 1 zettahash in play, Foundry controls 272 EH/s, about 27% of the network’s compute. Antpool holds 192 EH/s, or 19.19% of the total. ViaBTC contributes 110 EH/s, around 11% of aggregate power. Together, these three pools account for 574 EH/s—57.4% of the 1 ZH/s.
At this scale, mining resembles a supercomputer, intensifying efficiency races, consolidating advantage for well-capitalized pools, and pressuring marginal operators. Expect hardware upgrades, energy deals, and scrutiny to shape who prospers as difficulty adjusts and zettahash-level performance hardens into the baseline.
