With the official launch of the Brevis coChain on mainnet—we are excited to share another milestone alongside our launch, Ankr has joined the Brevis coChain Actively Validated Service (AVS) mainnet by leveraging EigenLayer’s cutting-edge tech stack to serve as a node operator! This collaboration represents a leap forward in strengthening the ZK coprocessing infrastructure for Web3 as a whole.
Our partnership with Ankr not only enhances the economic security of Brevis coChain but also integrates with Ethereum’s existing security layer through EigenLayer. As a Brevis coChain AVS node operator, Ankr will join in coprocessing with other operators to collectively generate optimistic results for requests received from smart contracts and dApps through EigenLayer’s restaking infrastructure. Then provide the opportunity for those results to be challenged by a Zero-Knowledge Proof generated by Brevis’s ZK proving stack.
Built on top of EigenLayer as a dual-quorum PoS network, Brevis coChain benefits from pooled economic security with restaking. Liquid restaking is the process of depositing liquid staking tokens (LSTs) into external systems like rollups or oracles to provide them with an additional layer of security, while liquidizing LSTs for users to earn extra yields. With the dual-quorum design, Brevis allows Ankr and its delegators to support the coChain AVS through both LSTs/native ETH and an additional token. This not only presents an exciting opportunity for stakers and delegators to earn additional rewards on top of their ETH and LSTs, but also enables a rich, resilient model for Brevis that taps into the security of ETH already staked on Ethereum mainnet.
Brevis coChain AVS
Brevis is a smart ZK coprocessor that empowers smart contracts to read the full historical on-chain data from any chain and then run customizable computations in a completely trust-free way.
Previously, Brevis only operated using a “pure-ZK” model until we launched Brevis coChain, which introduced a new “propose-challenge” ZK Coprocessor model. Brevis coChain is a PoS network that accepts coprocessing requests from smart contracts and optimistically generates coprocessing results through PoS consensus then allows those results to be challenged with a ZK proof—significantly lowering costs, reducing latency, and increasing scalability.
By running Brevis coChain as an Eigenlayer AVS, we can expand and extend the Ethereum-level crypto-economic security by easily reusing the already staked ETH without having to unstake them.
What is Ankr
Ankr is an all-in-one Web3 developer hub that provides a full suite of tools to build Web3 apps and power them with high-performance connections to 45+ blockchains. They provide multi-chain dApp development tools, blockchain engineering services, crypto staking solutions, and a globally distributed node infrastructure that makes it all possible. Ankr’s products make it easy for anyone to build and earn on Web3 and participate in the crypto economy for a more decentralized, democratic, and user-owned web experience.
By opting in as an AVS node operator for Brevis, Ankr commits to providing an essential service for the project—including operating validators for Brevis and ensuring smooth and secure operations for the protocol. This has several benefits including high-performance node operations for the Brevis coChain AVS, distributed validation, and around-the-clock support & maintenance!
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 Eigenlayer. Ankr acts as the cornerstone technology behind the Eigenlayer, eliminating the limitations that previously hindered growth. With seamless AVS node operation, innovative liquid staking solutions, and Rollups as a Service platform, Ankr is excited for the launch of all these ambitious Web3 projects.
Next Steps
We are excited to be working closely with Ankr and look forward to exploring the various integration possibilities with Brevis’s ZK Coprocessor for different features or use cases in Ankr’s platform!
