Hash rate refers to the total computational power being used to process transactions and secure a proof-of-work blockchain network. It measures how many cryptographic hash calculations are performed per second by miners. A higher hash rate indicates greater network security, as more computing power is required to alter the blockchain. Hash rate can fluctuate based on miner participation, hardware efficiency, and market conditions. It is commonly expressed in units such as hashes per second, terahashes, or exahashes.
