Introduction

Brevis is a highly efficient ZK coprocessor that empowers smart contracts to read from the full historical on-chain data from all supported blockchains and run customizable computations in a completely trust-free way. With the power of trust-free historical data, Brevis enables exciting new use cases like data-driven DeFi, user retention and engagement features, trust-free active liquidity management, omnichain activity-based identity, and many more. Read this blog for examples.
Integrating your dApp with Brevis only takes three simple steps:
  1. 1.
    Data Access: Smart contracts, through Brevis's APIs, can trustlessly access the full historical on-chain data, such as states, transactions, and events, from Ethereum and other chains.
  2. 2.
    Computation: Developers then can build and deploy their customized business logic as application circuits without any prior knowledge of ZK using Brevis's SDK. Brevis runs the computation and generates a ZK proof off-chain for the results.
  3. 3.
    Using the Results: The computation results, along with the ZK proof, are submitted back on-chain for application smart contracts to seamlessly verify and consume.
