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 . WebProof Of Work is used to determine the representation of the majority. Determining the majority is one of the keys in being able to come to consensus on decisions. But in order to determine the majority, Proof Of Work uses Cryptographic Puzzles (or Proof of Work Puzzles) – making them just as important. But how do these Proof Of Work puzzles ... Web“Proof-of-work” is a consensus mechanism that employs a mathematical, cryptographic puzzle to validate each transaction in a blockchain. Due to the complex nature of these puzzles, PoW systems often require the expenditure of lots of processing power before additional transactions are accepted into the network’s global ledger. billy ray on youtube

"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… " - Cryptographic puzzles and proof-of-work
