Lagrange is a modular cryptographic infrastructure project that leverages zero-knowledge (ZK) proofs to enable verifiable computation and secure cross-chain interoperability. Its primary goal is to address the scalability and privacy challenges within the blockchain ecosystem.
Lagrange's technology is built around three core components:
- ZK Prover Network: This is a decentralized network of operators that generates ZK proofs on demand. It acts as an "infinite proving layer," providing a scalable and decentralized solution for rollups, dApps, and other blockchain ecosystems.
- ZK Coprocessor: This component functions as a trustless query engine for blockchain data. It allows smart contracts to perform intensive off-chain computations with cryptographic proofs of correctness, which unlocks complex applications that would be impossible to run on a blockchain's main network due to high costs and slow speeds.
- DeepProve: This is a system for verifiable AI and machine learning. It uses ZK proofs to prove that an AI model's output is correct, which is crucial for applications where trust in the model's computation is essential.
How it solves a problem
Imagine you want to calculate the average price of an asset across multiple different blockchains. This would typically be a complex and expensive process that requires relying on a third-party oracle. Lagrange makes this process more efficient and secure by moving the heavy computation off-chain, generating a ZK proof to verify the result, and then submitting that proof to the blockchain. This method allows for complex, multi-chain computations to be done quickly, cheaply, and with a high degree of security.
