A computational puzzle is a problem requiring significant computational effort to solve but is easy to verify. In blockchain, this typically refers to the proof-of-work mechanism, where miners compete to find a specific hash value by performing numerous calculations. Solving these puzzles secures the network by making it costly to alter transaction history.
Context
The debate around the environmental impact of proof-of-work blockchains centers on the energy consumption associated with solving these puzzles. Innovations in consensus mechanisms, such as proof-of-stake, aim to replace or reduce the reliance on computationally intensive puzzles, influencing network security and decentralization discussions.
A novel Proof of Useful Work protocol embeds SNARK generation into consensus, solving energy waste and creating a decentralized verifiable computation market.
