Brevis coChain has become our newest Eigen Layer AVS client and collaborator on Day 1 of their mainnet launch. Together, we're enabling smart contracts to utilize the full historical on-chain data from any chain, and run customizable computations in a completely trust-free way.

Providing a Complete Solution for Eigen Layer AVS Protocols

Ankr is helping make a powerful new generation of Web3 protocols possible by providing the essential infrastructure that unlocks shared security with Ethereum for innovative projects deploying with Eigen Layer. Ankr acts as the cornerstone technology behind the Eigen Layer, eliminating the limitations that previously hindered growth. With seamless AVS node operation, innovative liquid staking solutions, and Rollups as a Service platform, Ankr is expediting the launch of these ambitious Web3 projects.

What Is Brevis Network and Brevis coChain AVS?

Brevis is a smart zero-knowledge coprocessor that empowers smart contracts to read from and utilize the full historical on-chain data from any chain and run customizable computations in a completely trust-free way. Using Brevis, developers can create a multitude of data-driven features — DEXes are able to build VIP loyalty programs based on a user’s past trading volume; active liquidity management protocols can trigger predefined user intents with ZK-verified on-chain states and events; AMMs can have strong LVR protection and more robust farming reward distribution programs; protocols can utilize multi-dimensional ZK-reputation metrics to segment users and provide a personalized UX based on an address’s on-chain footprint.

Initially, Brevis operated only via a "pure-ZK" model, wherein ZK proofs were always generated upfront and verified on-chain before coprocessing results could be used. While the pure-ZK model provides simplicity and a trustless framework, many dApps seek a more flexible solution that can be cost-effective across different scenarios based on the value and time sensitivity of a request, while still ensuring security through robust ZK guarantees.

To meet this demand, Brevis introduced the coChain AVS powered by EigenLayer restaking, marking the beginning of a novel ZK Coprocessor architecture that combines the strengths of crypto-economic security and ZK fraud proof. Upon receiving a request, the Brevis coChain first produces crypto-economically secured coprocessing "proposals", which are open to "challenges" through ZK fraud proofs. In the majority of cases where challenges are not initiated, the results can be used directly in smart contracts without incurring the steep costs associated with ZK proof generation and verification. In addition to significantly lower costs, the introduction of the coChain AVS also supports essential features like proof of non-existence and proof of completeness, which were previously very difficult to attain using the pure-ZK framework.

How Does Brevis Benefit Ethereum and Other Blockchains?

Brevis can reduce on-chain workloads, enhance security, and unlock new functionalities, positioning it as a valuable tool for developers building scalable and secure blockchain applications.

  • Migrating Heavy Computation Off-chain: Smart contracts require an infeasible amount of computational resources to execute data-driven or complex logic, resulting in impractical fees and wait time on the users’ end. To resolve that, Brevis migrates the computation off-chain and allows smart contracts to access full historical on-chain data and run customizable computations in a trust-free manner. With advanced ZK cryptographic algorithms and large-scale parallel computing, Brevis can process complex computations on thousands of transactions in just a few minutes.

  • Enhanced Security and Privacy: Brevis' zero-knowledge proofs ensure the validity of data access and computations without the need to reveal the underlying data. This enhances the throughput of Ethereum while safeguarding user privacy.

  • Facilitating Interoperability: Brevis plays a big role in fostering interoperability between blockchains. By enabling trustless data access and verification on various chains, Brevis creates opportunities for DeFi protocols and other applications to build data-driven features across different blockchain ecosystems.
