Definition ∞ A Verification Game is a cryptographic protocol or economic mechanism designed to ensure the truthful execution of computations or data processing, particularly in decentralized or untrusted environments. Participants in such a game can challenge the validity of a computation, and if successful, receive a reward, while dishonest actors face penalties. This game-theoretic approach incentivizes correct behavior and discourages fraud without requiring every participant to perform the entire computation. It secures integrity through economic means.
Context ∞ Verification games are a critical component of optimistic rollups and other layer-2 scaling solutions for blockchains, enabling efficient and secure off-chain computation. The effectiveness of these games relies on carefully designed incentive structures and the ability to quickly resolve disputes regarding computational correctness. Continued development focuses on making these games more efficient and robust against various attack vectors to enhance blockchain scalability.
