== How hash functions work == | |||
Mining is based on cryptographic '''hash functions'''. A hash function is a special kind of cryptographic process that generates a fixed amount of bits given an arbitrary input. An example of an hash function is SHA-256 (which is used to secure the [[Bitcoin]] blockchain or Keccak-256 (used in [[Ethereum|Ethereum)]]. | |||
Hash function are one-way functions, this means that it is easy to derive the output given the input, but it is ''computationally infeasible'' to do the opposite; this means that one cannot retrieve the original input given the output of the hash function. Also, for any given input there is a unique output such that, even if only 1 bit of the input is altered, the output changes completely and is completely unrelated from the previous one. | |||
