Definition

Proof-of-Useful-Work is a consensus mechanism where computational effort expended by miners or validators contributes to solving real-world problems rather than solely securing the blockchain. Unlike traditional Proof-of-Work, which often involves arbitrary calculations, PoUW directs this computational power towards tasks like scientific research, data compression, or artificial intelligence training. This method aims to align network security with societal benefit. It seeks to mitigate environmental concerns associated with energy-intensive consensus.
