The term **'BTC hashrate'** refers to the total computational power being used by miners on the Bitcoin network to process transactions and secure the blockchain. It measures how many hash computations are performed per second to find a valid block, typically expressed in units such as terahashes per second (TH/s), petahashes per second (PH/s), or exahashes per second (EH/s). A higher hashrate generally indicates a more secure and robust network, as it becomes harder for any single entity to gain control over the mining process.
