Bitcoin hashrate was newly set to a second (1 Zh/s) for the first time, according to GlassNode data, at 1 second per second on the seven-day moving average.
The hash rate is the average estimated number of hashs per second generated by the miners that secure the network. Using a 7-day moving average is important as it smoothes out the variability of natural block time.
The network has briefly mentioned 1 Zettahash several times this year, but this is the first time it has been maintained on a seven-day moving average.
To make this a point of view, one Zetta hash equals 1,000 EXA hash (EH/S). Bitcoin first crossed one EH/s threshold in 2016, and in 2025 the network hashrate rose from around 800 EH/s at the beginning of the year to 1 ZH/s today.
This rapid increase in computing power is expected to trigger a major difficulty adjustment of over 7% over the next two days.
The difficulty adjustment occurs about every two weeks, ensuring that new blocks are added to the blockchain about every 10 minutes, regardless of the amount of total online mined power. Following this change, the difficulty level rises to 138.96 trillion
