Definition ∞ Proof of Useful Intelligence describes a class of consensus mechanisms or computational models where network participants perform valuable real-world computations to secure the blockchain. Instead of arbitrary cryptographic puzzles, the work contributes to scientific research, artificial intelligence training, or other societal benefits. This approach aims to make the energy expenditure of securing a network productive.
Context ∞ Proof of Useful Intelligence is a developing concept in blockchain technology, seeking to address environmental concerns associated with traditional proof-of-work systems. Discussions often highlight its potential to align network security with public good, offering a more sustainable model. Observing research and development into specific applications provides insight into the feasibility and adoption of this innovative approach.
