Definition ∞ A PoUW (Proof-of-Useful-Work) consensus protocol is a mechanism where the computational effort expended by participants serves a dual purpose. Beyond securing the network, the work contributes to solving real-world computational problems. This design aims to make the energy consumption of consensus economically productive. It contrasts with traditional proof-of-work, where computation is solely for security.
Context ∞ PoUW consensus protocols are a subject of considerable interest and discussion in crypto news, particularly in response to environmental concerns surrounding traditional proof-of-work. Research and development focus on identifying suitable useful-work problems and ensuring network security is not compromised. The viability of integrating productive computation into blockchain consensus remains a key area of exploration.
