Hash<\/h1>\n\n\n\n

A hash is an alphanumeric string and end product of a cryptographic hash function<\/a> (CHF). The size of a hash is different depending on what CHF is used, but all hashes from a given CHF have the same size. A hash\u2019s size is represented in storage bits (computer storage bits).<\/p>\n\n\n\n

Bitcoin uses a CHF called SHA-256 (Secure Hash Algorithm) that generates a 256 bit hash. Each digit in the 256 hash represents 4 bits, so the length of the hash is an alphanumeric string of 64 characters.

A hash consists of the block header<\/a> and a nonce<\/a>.<\/p>\n\n\n\n
