While Bitcoin’s hashrate hums along at 1 zettahash per second (ZH/s), the network’s difficulty just cranked up another 4.63%, locking in a fresh peak at 142.34 trillion.
Bitcoin Difficulty Hits Fresh High With Network Power Steady Over 1 Zettahash

Bitcoin blocks just got 4.63% tougher to mine after the latest difficulty bump. As of 2:35 p.m. Eastern time Friday, the network’s hashrate clocks in at 1,016.17 exahash per second (EH/s), cruising beyond the 1 zettahash (ZH/s) mark. At block height 915,264, the hashrate briefly touched 1.13 ZH/s, with the average block time settling at roughly 9 minutes and 1 second.

Blocks are still popping up quickly, but that tempo could ease under the new difficulty setting—especially with miners already battling slimmer margins this September. Right now, hashprice—the going estimate for a single petahash per second (PH/s)—sits 7.91% below last month’s level. On Aug. 19, it was $55.78 per PH/s, while today it’s down to $51.37.
