After vaulting past the 1 zettahash per second (ZH/s) threshold, Bitcoin’s mining difficulty climbed 4.89% to reach an all-time pinnacle of 136.04 trillion. This adjustment, paired with softened bitcoin prices, has tightened the squeeze on mining participants.
Mining Just Got Harder: Bitcoin Pushes Difficulty to Lifetime Peak
According to the seven-day simple moving average (SMA) tracked by hashrateindex.com, Bitcoin’s total hashrate reached 1,013 exahash per second (EH/s) on Sept. 2, surpassing the symbolic threshold where 1,000 EH/s equals a single zettahash.

Yet three days later, at block 913248, difficulty adjusted higher as average block times over the 2,016-block span settled near nine minutes and 32 seconds. The rise turned out to be a 4.89% jump, pushing the difficulty from 129.70 trillion to a massive 136.04 trillion. This difficulty adjustment applies uniformly to all miners, regardless of scale.

In effect, a worker’s top share does not diminish, but it loses weight as an indicator of proximity to striking a block once the network elevates the threshold. At present, after peaking at 1,013 EH/s, Bitcoin’s hashrate has retreated to roughly 961 EH/s, with the tougher difficulty pushing average block intervals to about 11 minutes 4 seconds.
The latest adjustment illustrates how Bitcoin’s self-correcting mechanism continues to shape the rhythm of block production, reminding miners that efficiency is constantly tested against the network’s evolving standard. For participants, the shifting balance highlights both the resilience of the system and the perpetual contest of capital, energy, and ingenuity that defines the pursuit of block rewards in this digital arena.
