Brevis ZK Coprocessor is transforming smart contract functionality by enabling unlimited off-chain computation and full access to historical and cross-chain data. This innovation, powered by zero-knowledge proofs, allows decentralized applications (dApps) to implement features like personalized fees, dynamic rewards, and AI-driven decisions, which were previously costly or unfeasible due to high gas fees. By shifting heavy computations off-chain and only posting a minimal ZK proof on-chain, projects can reduce gas costs by 90-99%. For instance, Euler Finance uses Brevis to distribute LP rewards with negligible gas costs. Brevis also facilitates trustless access to any past block or contract state across chains without relying on oracles or bridges, enhancing security and efficiency. The integration of Brevis with Pico zkVM further boosts computational capacity, enabling over 100 times more compute per block at the same verification cost. This advancement is already being utilized by platforms like MetaMask and Trusta AI for applications such as on-chain reputation and cross-chain rewards.
