Bitcoin's mining difficulty fell by 5.01% due to a July 21 adjustment — the most it has dropped since July 2021.
The data was published by BTC.com, which tracks network mining difficulty and posts an update roughly every two weeks when the adjustments take place.
The network's hash rate has fallen by about 8.9% from July 6, the date of the last update, according to data compiled by The Block Research.
Mining difficulty refers to the complexity of the mathematical process behind mining, during which miners are repeatedly trying to find a hash below a set level. Miners that "discover" this hash win the reward for the next transaction block.
Mining difficulty adjusts every 2,016 blocks (roughly every two weeks) in sync with the network's hash rate.
