Bitcoin mining difficulty increased 1.31% at block height 965664 to 127.45 trillion, its eighth increase of 2026 and the network’s 18th difficulty adjustment since January. Hashprice, the estimated daily revenue from one petahash per second of mining power, rose 22.24% over roughly 30 days to $39.63 per PH/s per day from $32.42. Hashrate, the network’s total computational power, remained at 934 EH/s, below 1 ZH/s. Fees accounted for only 0.43% of miners’ total rewards over the previous 24 hours, underscoring miners’ reliance on Bitcoin’s price rather than transaction fees in 2026. Difficulty adjusts every 2,016 blocks to keep average block production near 10 minutes. Although eight increases added 33.34% this year, ten decreases totaling 45.27% produced a net decline of 11.93%; difficulty fell from 146.47 trillion to 127.45 trillion, a 13% drop. The source says the flat hashrate suggests miners are proceeding cautiously and may be encountering hardware limits, with sharper Bitcoin price moves potentially making these conditions more visible.
