A unit of measurement for the computational power of mining equipment. The mining process involves solving a vast number of complex mathematical problems, only after which can the miner receive units of a cryptocurrency. In doing this, all previously completed operations are stored on a shared server that all users can access. Bitcoin miners find the hash of different combinations, which gives them access to secret keys and new operations. This complicated mathematical process requires a powerful, specialised device that can find the required hash as quickly as possible. The best way to know the hashrate of a piece of equipment is through practical use as the information provided by manufacturers may not always be correct.
