Hashrate, difficulty and the mining calculator
The hashrate is the combined computing power of all bitcoin miners — how many guesses per second they make at the next block. Difficulty sets how hard each guess is, and it resets every 2,016 blocks (about two weeks) so that blocks keep arriving about every ten minutes: when hashrate rises, difficulty follows.

Hashrate & difficulty: FAQ
What is bitcoin's hashrate today?
About 1,057 EH/s (exahashes per second), averaged over three days. That is 1,056,962,706 terahashes per second.
When is the next difficulty adjustment?
In 618 blocks, around October 29, 2026. At the current pace difficulty would change by about +4.9%; the estimate changes as blocks arrive.
Why does hashrate go up?
More and more efficient machines join when mining is profitable — after price rises, or when new chips come out. It falls when the price drops, after halvings cut the reward, or when miners shut down (for example China's mining ban in 2021).
Does a higher hashrate make bitcoin more secure?
Yes, in the sense that attacking the network (rewriting recent blocks) needs more than half the hashrate, so more hashrate makes an attack more expensive.
