**Hashing** is a crucial procedure in a blockchain network repeated frequently by miners. The use of hashing on a Proof of Work blockchain constantly can help in finding a suitable signature. A hash is a function capable of taking an input and rendering output in the form of an alphanumeric string you can identify as the hash value. Every block has a hash value responsible for validating the previous transaction and its own hash value.
