Proof of work - Wikipedia

WebProof of work (PoW) is a form of cryptographic proof in which one party (the prover) proves to others (the verifiers) that a certain amount of a specific computational effort has been expended. Verifiers can subsequently confirm this expenditure with minimal effort on their part.

What is a hash function in a blockchain transaction?

WebA cryptographic hash function should be computationally efficient, meaning that it must be quick in performance to create the hash value. It has to be deterministic - every time you put in a certain input, it has to produce the same output and to be pre-image resistant which means it cannot reveal any information about the input in the output.
