Overview
Lagrange Labs develops AVS protocols built atop EigenLayer restaking, including the Lagrange State Committees (LSCs) and the ZK Coprocessor.
LSCs act as lightweight ZK “clients” for optimistic rollups—generating state proofs for rollups like Arbitrum or Mantle without waiting for long fraud-proof windows.
The ZK Coprocessor enables complex off-chain computation with cryptographic proof, letting developers perform heavy tasks securely and verifiably on-chain.
• Imagine getting real-time cross-chain data integrity without waiting, or offloading heavy analytics to a “prover cloud” that guarantees correctness.
• Lagrange is like building a shared digital security zone—one that scales naturally as more actors join, powered by Ethereum-level collateral.
• It turns otherwise latent rollup transactions into “fast-mode verified truth”—for faster bridges, messaging, and trust.
• And for AI, it’s like giving agents a cryptographically trusted computation engine - where every inference is provably accurate.
LSCs: Scalable Trust Layer
• Comprised of operator nodes restaked via EigenLayer, each requiring 32 ETH to participate.
• State proofs are aggregated via SNARKs—attestations that clients can verify quickly and trustlessly.
ZK Coprocessor & Prover Network
• Supports computation-heavy tasks outside the chain and returns results as ZK proofs.
• Operated by high-integrity institutions (e.g. Coinbase, Kraken, OKX), incentivized for liveness and accuracy.
Super-linear Security & Fast Finality
• Supports an unbounded set of validators—unlike Ethereum’s capped 512 Sync Committee—continuously scaling economic security.
• Significantly reduces cross-chain latency by providing “fast-mode” state verification for rollups.
Architecture
• LSC nodes verify rollup headers via watchers and jointly sign attestations; sequencer aggregates and enables SNARK proofs.
• The ZK Coprocessor runs off-chain workloads, coordinated via a Gateway-Prover system, and returns proofs on-chain.
Ecosystem Integrations
LSCs live on Optimism, Arbitrum, Base, Mantle, and Polymer ecosystems—expanding cross-chain reach.
