Commitees Overview

Lagrange Labs cross-chain state committee provide a more secure alternative to isolated k of n bridges for applications that require trustless cross-chain states. Lagrange cross-chain state committees are not designed to replace proofs of consensus but instead are an alternative mechanism for chains whose finality or consensus is not proveable within a zero-knowledge context.

The security of the Lagrange cross-chain state committee is derived from an ever growing, dynamically sized set of nodes with leveraged rehypothecated collateral, either restaked with EigenLayer or staked with liquid staking derivatives, such as Rocket Pool.

The Lagrange cross-chain state committee is designed to be extensible to generate state proofs for any chain, irrespective of consensus mechanisms, sequencer or validator set specifications.

As such, the collateral behind each attestation can scale dynamically as is required to create secure proofs for each given chain. This property is what enables the Lagrange cross-chain state committee to be the first protocol to enable generalizable state proofs of any arbitrary chain with super-linear security.

The Lagrange State Committee Testnet will launch for Arbitrum, Optimism & Base in Summer 2023.
