Lagrange: Cross-chain State Verification Protocol Based on Zero-Knowledge Proofs

Lagrange is a cross-chain state verification protocol (designed to make Zero-Knowledge Proofs )ZK Proofs( of blockchain data portable )and composable (across different blockchains. Inspired by Lagrange interpolation )Lagrange polynomials( in mathematics, this protocol allows for trustless state synchronization between chains, enabling smart contracts on one blockchain to rely on verified data from another blockchain. Protocol architecture )Protocol Stack( ZK State Proof Engine Creates compact ZK Proofs for blockchain data ) such as wallet balances, smart contract states (. Helps verification of states become quick, resource-efficient, and can be checked in a decentralized manner. Cross-Chain Messaging Layer The cross-chain messaging layer is responsible for transporting verified proofs to the destination blockchain. Ensures that the transmitted data is not altered or tampered with. Verification Contracts Lightweight smart contracts deployed on the destination chain to verify and validate the legitimacy of proofs. Developer SDK A toolkit that helps developers integrate cross-chain state verification capabilities directly into dApps. Helps speed up the deployment process and reduce technical barriers. Current application Cross-chain lending market: Collateral on Chain A can secure a loan on Chain B. Multi-chain NFT gaming: In-game assets can exist and move across multiple blockchains. Multi-chain DAO Governance: Synchronizing voting rights and voting results across different blockchains. Tokenomics – Token LA Fee for submitting proof: The proof creator receives payment fees in LA tokens. Governance ): LA holders have the right to vote on adjusting protocol parameters and selecting supported chains. Staking: Validators stake LA to participate in the proof verification process. Why is Lagrange important? Lagrange addresses one of the biggest issues of blockchain: secure interoperability (.

By proving the cross-chain state, Lagrange opens up the possibility of composability at the application layer, allowing for the construction of complex dApps and tight integration between blockchains. Risks & Challenges Proof creation cost: Creating ZK Proof still requires a lot of computational resources. Difficulty in application: dApp developers need to integrate the SDK into their products. Dependent on chain security: The safety of Lagrange is still tied to the security of both the source blockchain and the destination blockchain. @lagrangedev #lagrange $LA {spot})LAUSDT(
