Bitcoin’s 7-Day Average Hashrate Sustains 1 Zettahash for First Time

The sustained jump positions the network for an estimated difficulty increase of more than 7% within days.

Overview

  • Glassnode data show the seven-day moving average hit 1 ZH/s, with Blockchain.com charts confirming the first break above 1,000 EH/s on the weekly trend.
  • The network’s capacity has risen from roughly 800 EH/s at the start of 2025 to this level, reflecting rapid growth in mining compute.
  • On-chain projections indicate a difficulty adjustment exceeding 7% is due within days, which CoinDesk says would be the year’s second-largest upward change.
  • JPMorgan reports August’s average hashrate at 949 EH/s as daily block reward revenue fell 4% and gross profit per EH/s declined 7% from July.
  • Investor interest and capacity additions continued as the combined market value of tracked U.S.-listed miners hit a record, with TeraWulf’s Fluidstack colocation and IREN’s GPU expansion cited despite a softer bitcoin price.
