As the Brevis coChain enters the mainnet stage, we’re thrilled to announce a significant milestone: RockX’s operator is now part of the Brevis coChain Actively Validated Service (AVS) mainnet, powered by EigenLayer’s advanced technology stack. This partnership marks a significant advancement in fortifying the ZK coprocessing infrastructure for Web3, showcasing our commitment to innovation and collaboration in the blockchain space.
RockX is designed to natively restake and harness additional EigenLayer rewards by bringing together institutional-grade security and additional yield to liquid staking.
Our collaboration with them not only bolsters the economic stability of Brevis coChain but also seamlessly integrates with Ethereum’s established security framework via EigenLayer. As a node operator for Brevis coChain AVS, RockX will collaborate with other operators in coprocessing to collectively produce optimistic outcomes for requests originating from smart contracts and dApps through EigenLayer’s restaking infrastructure. Additionally, this partnership offers the chance for these outcomes to be contested through 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 RockX 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 RockX
RockX is a global blockchain node network and gateway for users to seamlessly access Web3, offering institutional-grade solutions and a full suite of developer tools for users to stake and build on all major Proof-of-Stake blockchains.
With its foundations rooted in staking, protocol research and infrastructure design, RockX has built numerous access nodes for users to interact with more than 20 layer 1 and 2 protocols — driving greater accessibility and furthering adoption of blockchain technologies.
With over 20 major tokens supported and over USD 2 billion staked in cumulative token value since 2018, RockX is the leading institutional provider of staking and blockchain infrastructure.
RockX is embracing the opportunities within the Eigenlayer ecosystem, demonstrating its commitment to fostering growth within the community. With innovative AVSs like Brevis gaining prominence and expected to play a pivotal role in the ecosystem, we are looking forward to the successful launch and adoption on mainnet. This marks a notable advancement in the partnership between RockX and Brevis, signifying progress towards our shared goals within the blockchain landscape.
Next Steps
We are excited to be working closely with RockX and look forward to exploring the various integration possibilities with Brevis’s ZK Coprocessor for different features or use cases in RockX’s platform!
