With the official launch of the Brevis coChain on mainnet—we are excited to share another milestone alongside our launch, Nethermind 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.
Nethermind is renowned for its contributions to the Ethereum ecosystem, including providing reliable non-custodial staking solutions tailored for Proof-of-Stake (PoS) blockchains. Our collaboration with Nethermind 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, Nethermind will join coprocessing with other operators to collectively generate optimistic results for requests received from smart contracts and dApps through EigenLayer’s restaking infrastructure, and provide the opportunity for the 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 Nethermind 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 Nethermind
Nethermind is a blockchain research and software engineering company empowering developers and enterprises worldwide to access and build on decentralized systems.
Nethermind 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 collaboration between Nethermind and Brevis, signifying progress towards our shared goals within the blockchain landscape.
Next Steps
We are excited to be working closely with Nethermind and look forward to exploring the various integration possibilities with Brevis’s ZK Coprocessor in the ecosystem!
