What is Brevis coChain?
Brevis is a cutting-edge ZK (Zero-Knowledge) coprocessor designed to enhance smart contracts by providing access to the full historical on-chain data from various supported blockchains. This capability enables developers to perform customizable computations without needing to trust any centralized entity, paving the way for innovative applications across different domains, such as decentralized finance (DeFi), user engagement, liquidity management, and cross-chain identity solutions.
Integrating your decentralized application (dApp) with Brevis involves three straightforward steps:
- Data Access: Developers can leverage Brevis's APIs to enable their smart contracts to trustlessly access comprehensive historical on-chain data. This includes vital information like states, transactions, and events from Ethereum and other blockchains.
- Computation: With the data accessed, developers can create and deploy custom business logic as application circuits without requiring extensive knowledge of Zero-Knowledge proofs. Brevis's SDK facilitates this process by executing the computations off-chain and generating ZK proofs to validate the results.
- Using the Results: The results of the computations, accompanied by the generated ZK proof, are submitted back on-chain. This allows application smart contracts to seamlessly verify the outcomes and utilize them in their operations.
For a practical demonstration, you can explore a concrete example showcasing a trading fee discount hook for Uniswap v4, built using the Brevis SDK.
The following sections will detail these steps, providing an end-to-end workflow that illustrates how Brevis enhances the capabilities of smart contracts, enabling trust-free interactions and innovative functionalities in the blockchain ecosystem. This streamlined integration process empowers developers to harness the full potential of historical data and ZK technology, driving the next wave of decentralized applications.
