Hash Rate is a measure used to describe how fast a blockchain network can process transactions and complete hashing algorithms. In the context of cryptocurrency, hash rate refers to the number of hashes (or mathematical solutions) that a miner can calculate in one second. This value is usually expressed in units of hashes per second (H/s), with larger variations such as kilohash per second (KH/s), megahash per second (MH/s), gigahash per second (GH/s), to terahash per second (TH/s) and petahash per second (PH/s).
