Blocks have been arriving roughly every 8 minutes 45 seconds, well inside the 10-minute target, and the network has now caught up with it. Difficulty rose 5.92% at block 971,712 on Friday, October 16, from 132.72 trillion to 140.58 trillion, the highest reading since March 5, according to Bitcoin.com News citing mempool.space. That made it the 10th increase in 21 adjustments this year and the third largest. Hashrate stands above 1 zettahash per second, 1,024.96 EH/s at the time of writing per HashrateIndex, and the fast blocks are already pushing the next estimate up: a further 14.24% around October 28, though only a few dozen of the epoch's 2,016 blocks had been mined when that figure was taken, so it can still swing a long way. Revenue is heading the opposite way. Hashprice, a miner's earnings per petahash per day, was $36.75 on October 16 against $37.56 on September 16, after twice topping $41 in the past month, including October 2. Higher difficulty on flat-to-lower hashprice squeezes every operator, and older machines on expensive power feel it first. Add Binance Pool's November 10 shutdown, and a chunk of hashrate has to find a new pool in the same weeks the cost of each coin climbs.
