With the official launch of the Brevis coChain on mainnet—we are excited to share another milestone alongside our launch, the Staking4All operator has joined the Brevis coChain Actively Validated Service (AVS) mainnet by leveraging EigenLayer’s cutting-edge tech stack! This collaboration represents a leap forward in strengthening the ZK coprocessing infrastructure for Web3 as a whole.
Staking4All is renowned for providing reliable non-custodial staking solutions tailored for Proof-of-Stake (PoS) blockchains. Our partnership with them 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, Staking4All 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 Staking4All 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 Staking4All
Staking4All offers trusted non-custodial staking services for Proof-of-Stake (PoS) blockchains, backed by years of experience in running full nodes, validator nodes, and RPC nodes since 2018. Prioritizing security and user control, they ensure your funds remain accessible and secure at all times. With a commitment to the principle of “not your keys, not your crypto,” they provide staking options for various leading ecosystems like Polygon, Polkadot, Near, and Harmony One, enabling easy participation in PoS consensus and decentralized finance.
It is no wonder that Staking4All is jumping at the opportunities presented by the Eigenlayer ecosystem. As active participants in the Eigenlayer Testnet for operators from the very beginning, Staking4All is committed to seeing the ecosystem grow. Shez, Co-founder of Staking4All remarked, “As Eigenlayer progresses and innovative AVSs like Brevis come to the forefront, we eagerly embrace this future. Brevis, a Smart ZK Coprocessor-based AVS, is poised to become a cornerstone in the landscape and we eagerly anticipate its successful launch and utilization on the mainnet, marking a significant stride forward in our partnership with Brevis.”
Next Steps
We are excited to be working closely with Staking4All and look forward to exploring the various integration possibilities with Brevis’s ZK Coprocessor for different features or use cases in Staking4All’s platform!
