Bitcoin has confirmed one of its largest downward mining difficulty adjustments on record, cutting difficulty by 10.09% at block 953,568 as weaker prices pushed more hashrate offline. The adjustment reduced Bitcoin mining difficulty from 138.96 trillion to 124.93 trillion, making it the network’s 11th-largest downward difficulty move ever and the second-biggest decline of 2026. The 2,016-block epoch took about 15.6 days to complete, well above Bitcoin’s roughly 14-day target window.
