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

Bitcoin's hashrate has reached 1 zettahash per second (1 ZH/s) on a seven-day moving average, achieving a new all-time high, according to Glassnode data.

The hashrate indicates the average number of hashes per second produced by miners securing the network.
This is the first sustained instance of 1 ZH/s on a seven-day moving average.
In comparison, 1 ZH/s equals 1,000 exahashes (EH/s); Bitcoin first surpassed 1 EH/s in 2016.
The hash rate increased from around 800 EH/s at the start of 2025 to 1 ZH/s today.
A significant difficulty adjustment of over 7% is expected in the next two days, marking the second largest upward adjustment of the year.
Difficulty adjustments occur approximately every two weeks to maintain block generation at around 10 minutes.
Following the adjustment, difficulty will rise to 138.96 trillion (T).
