Brevis is a zero-knowledge proof (ZK)-based co-processor network. Simply put, it addresses two major pain points in blockchain: limited computing power and data storage difficulties.

The scope of this technology is quite broad. We can look at it from several angles:

**DeFi**

DEXs like PancakeSwap and QuickSwap can use Brevis to automatically distribute loyalty rewards based on your historical transaction records or dynamically adjust transaction fees. Instead of a blunt one-size-fits-all approach, it truly understands each user's behavior patterns.

Lending protocols such as Euler and BeraBorrow are also experimenting with leveraging historical data to achieve more precise protocol incentives, which can improve the actual utilization of funds. Verification of real-world assets (RWA) is another new direction, essentially securely bringing off-chain asset data on-chain, allowing traditional financial assets to enter the blockchain with greater confidence.

**Cross-chain and Security**

Brevis can generate ZK proofs for cross-chain messages. For example, transferring assets between Ethereum and BNB Chain can be verified without relying on third-party trust, simply through cryptographic proof. This approach is more efficient and more secure.

It can also serve as a complex cross-chain data oracle, providing verification services for off-chain data to smart contracts.

**Privacy and Identity**

The zkDID concept allows you to have a verifiable digital identity credential on-chain without exposing personal sensitive information. This is a significant breakthrough for Web3 social and identity applications.
