Lagrange is redefining the way on-chain data is accessed. It utilizes zero-knowledge proof (ZK) technology to credibly bring off-chain computation results on-chain, allowing developers to access state information from different blockchains at a very low cost. This mechanism is similar to 'API calls' in Web2, but it achieves trustless result verification based on cryptography, representing a revolutionary upgrade in Web3 data reading.
At the core of Lagrange is its State Commit Network, a distributed proof system that aggregates and encapsulates multi-chain state data. Currently, it supports more than a dozen chains including Ethereum, BNB Chain, Arbitrum, and Polygon, with plans to expand to more L1/L2 networks in the future, providing underlying support for cross-chain data interaction.
Through Lagrange, developers can read contract variables from Chain A on Chain B and perform further logical processing within contracts, eliminating reliance on centralized price feeds or bridging contracts. This approach has extensive applications in DeFi liquidation, NFT cross-chain verification, and DePIN networks, significantly enhancing the cross-chain intelligence and security of dApps.
The ZK module is gradually being integrated into the Ethereum mainline, and Lagrange's ZK abstraction design will also enhance its compatibility, supporting more future L2 frameworks. As the modular chain expands, the demand for inter-chain interaction will continue to grow, and the 'trustless data access' represented by Lagrange will become a standard component. #Lagrange @Lagrange Official $LA
