Overview
Lagrange is a zero-knowledge infrastructure protocol enabling verifiable off-chain computations for on-chain smart contracts.
• Designed to unlock cross-chain interoperability without sacrificing security or decentralization.
• Allows developers to prove data correctness across multiple blockchains using ZK proofs
• Imagine a trust bridge where blockchains can exchange data like pen pals—except every letter is cryptographically sealed and verifiable.
• It’s like having a mathematical notary for every piece of data that travels between chains.
• With Lagrange, apps can access real-world or cross-chain data without needing blind trust in an oracle or midnight
• ZK Coprocessing Layer
Executes heavy computations off-chain, then proves results to any blockchain.
• Cross-Chain Proof Aggregation Verification
Batch-proofs for multiple chains to reduce gas and latency.
• Data Availability Verification
Ensures the data powering smart contracts is tamper-proof.
• Multi-VM Support
Compatible with EVM and non-EVM chains for broad developer reach.
• Optimized Prover Performance
Faster proof generation for near real-time application needs.
• Built on a STARK-based proof system with recursion for composable verifications.
• Provides chain-agnostic SDKs for developers to integrate ZK proofs into smart contracts.
• Designed for use cases in DeFi risk management, cross-chain governance, on-chain ML, and privacy-preserving apps.
• Integrated with multiple ecosystems including Ethereum, Polygon, and BNB Chain.
• Supports light clients for minimal on-chain footprint and cost efficiency.
