Even though snagging a bitcoin (BTC) block reward has become a grind, miners keep flexing their muscles and pushing the network higher.

With difficulty locked at 142.34 trillion, the hashrate punched a fresh record of 1,091 exahash per second (EH/s), the equivalent of 1.091 zettahash per second (ZH/s), according to hashrateindex.com.

That milestone landed on Sept. 20, 2025, and by Monday, Sept. 22—two days later—the hashrate is still cruising just shy of the peak, holding steady at 1,082.29 EH/s. This computational prowess has been relentless despite the massive difficulty and the fact that revenue is a lot lower than it was 30 days ago.

Bitcoin total hashrate according to hashrateindex.com over the seven day simple moving average (SMA).

Back on Aug. 22, a single petahash per second (PH/s) of hashrate—better known as hashprice—was fetching $57.12. Since then, the rate has slipped about 12.41%, landing at today’s going price of $50.03 per petahash. Even with the hashrate firing off massive numbers, block times have been zipping by faster than the usual 10-minute mark, clocking in at a brisk 9 minutes and 4 seconds.

If this pace keeps up through Oct. 1, 2025, the next difficulty retarget is on track to jump more than 10% based on current projections. If those projections hold, difficulty will print past 150 trillion, cranking the challenge of scoring a block subsidy up to a whole new level. In short, bitcoin miners better pack a lunch—because cracking the next block after the next difficulty hike will feel like arm-wrestling a heavyweight with one hand tied behind your back.
