WebAug 30, 2024 · Proof of work, which is used by Bitcoin, requires users to solve complex cryptographic puzzles before they are added to the blockchain. This is also known as cryptocurrency mining . Proof 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. The concept was invented by Moni Naor and Cynthia Dwork in 1993 as a way to deter denial-of-service attacks and other service abuses such as spam on a network by requiring some work from a service requ… dark chocolate wood floors
