WebBitcoin used to be mined on CPUs, then GPUs and FPGAs, but ultimately miners started designing their own ASIC chips, which were vastly more powerful than these early solutions. As the hash rate goes up, so does the mining difficulty, thus ensuring equilibrium. WebSecure Hashing Algorithm (SHA) -256 is the hash function and mining algorithm of the Bitcoin protocol, referring to the cryptographic hash function that outputs a 256 bits long value. It moderates the creation and management of addresses, and is also used for transaction verification.
