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. The concept was invented by Moni Naor and Cynthia Dwork in 1993 as a way to … Web1.1 Cryptocurrencies meet AI: Proof of Human-work Puzzles In this work we introduce the novel notion of Proofs of Human-work (PoH) which would be suitable for cryptocurrencies. Proofs of Human-work are fundamentally di erent from standard Proofs of Work. Informally, a PoH puzzle should be moderately hard for a human to solve meaning that
