The number of cryptographic hashes per second (H/s) a computer executes for blockchain mining such as Bitcoin. A hash rate may refer to computations in a single GPU in one computer, a crypto mining machine, or hundreds of machines in a mining datacenter (see
ASIC miner). See
cryptographic hash function.
Quintillions of Hashes per Second
For example, CleanSpark is a top North American public Bitcoin miner. In January 2022, its total hash rate exceeded 2 EH/s (two quintillion hashes per second). In that year, the company was rewarded with an average of 10 bitcoins per day, which means all the machines combined solved a mathematical puzzle 10 times (see
Bitcoin halving). The idea is that if hard work is done, even if just numbers being calculated in a computer, there should be a reward. Bitcoin's Satoshi Nakamoto employed that concept (see
Satoshi Nakamoto). See
space/time.
