“Bitcoin’s 7-day average hashrate has surpassed 1 ZH/s, setting a new record for the network’s computational security.”

Bitcoin’s hashrate has surpassed a historic threshold, holding at 1 zettahash per second (ZH/s) on a seven-day moving average for the first time, Glassnode data shows.

The hashrate reflects the total computing power securing the Bitcoin network. While the network has briefly touched this level before, sustaining it on a weekly average underscores accelerating growth in mining activity.

For context, 1 ZH/s equals 1,000 exahashes (EH/s). Bitcoin first crossed the 1 EH/s mark in 2016, and in 2025 alone, hashrate has climbed from around 800 EH/s in January to the current record high.

The surge in computing power is expected to trigger a difficulty adjustment of more than 7% within the next two days—potentially the second-largest upward shift this year. Difficulty adjustments, which occur roughly every two weeks, calibrate block production to maintain a steady pace of one block every 10 minutes. After the change, network difficulty is projected to rise to 138.96 trillion.

The milestone highlights continued investment in mining infrastructure despite recent price volatility, signaling long-term confidence in Bitcoin’s security model.
