Lagrange collaborates with Polymer

Lagrange collaborates with Polymer Labs to enhance blockchain interoperability by combining zero-knowledge (ZK) proofs with the Inter-Blockchain Communication (IBC) Protocol.

This integration will merge Lagrange’s State Committee, functioning as a ZK light client, with Polymer’s Ethereum interoperability hub that utilizes the IBC standard. As a result, it will enhance reliability and speed up transactions for Optimistic rollups.

Explanation of the Integration Process

The integration includes the steps outlined in the diagram below:

  • Operators of Lagrange State Committees generate ZK proofs attesting to the execution of L2 chains (currently available with Base and Optimism).
  • The attestation proofs are consumed by Polymer and an aggregated ZK proof encompassing multiple transactions across different rollups can be generated.
  • Polymer is then able to send the aggregated ZK proof to destination chains via a relayer.

Exploring Uncharted Territories with Lagrange and Polymer

By combining Lagrange’s ZK primitives with Polymer’s IBC clients, this method reduces costs and simplifies the verification of individual chain states. Moreover, it offers a more effective and dependable approach to linking various blockchains. Lagrange is an Actively Validated Service (AVS) on EigenLayer, and the integration of Polymer with EigenDA enhances shared security via EigenLayer’s restaking model.

The integration of Lagrange and Polymer, backed by EigenLayer’s restaking framework, represents a significant advancement in blockchain interoperability. This development brings enhanced efficiency, security, and scalability to the Ethereum ecosystem.

Additionally, Lagrange and Polymer will delve into future collaboration initiatives as part of this integration.

  • Deploying a State Committee to attest to the state of Polymer’s L2
  • Expanding State Committee and IBC support to new rollup ecosystems
  • Integrating Lagrange’s ZK Coprocessor with Polymer’s interoperability capabilities

Lagrange Labs created Zero-Knowledge Coprocessing protocol for verifiable computations across blockchains. Their decentralized network generates ZK proofs off-chain for on-chain submission, enhancing efficiency and cost-effectiveness. This enables innovations in cross-chain interoperability and complex computations over big data.

Polymer enhances the Ethereum ecosystem with IBC, combining Optimism stack, Eigenlayer, and Cosmos SDK for secure and scalable interoperability.
