Bitcoin hashrate has reached 1 Zettahash per second (1 zh/s) In a seven -day mobile average for the first time, establishing a new maximum of all time, according to Glassnode Data.
The hashrate is the estimated average number of hashes per second produced by the miners who ensure the network. Using a seven -day mobile average is important because it softens the variability of natural blocking time.
The network has briefly touched 1 Zettahash several times this year, but this is the first time it has been held in the seven -day mobile average.
To put this in perspective, 1 Zettahash is equal to 1,000 hashes exa (Eh/s). Bitcoin first crossed the threshold of 1 eh/s in 2016, and in 2025 the hash rate of the network has increased from around 800 eh/s at the beginning of the year to 1 zh/s today.
This rapid increase in computer power is expected to trigger a significant difficulty adjustment of more than 7% in the next two days, which would mark the second largest ascending adjustment of the year.
The difficulty adjustments occur approximately every two weeks and ensure that new blocks are added to the block chain approximately every 10 minutes, regardless of the total amount of total mining power online. After this change, the difficulty will increase to 138.96 billion (T).
