The blockchain is a 'world computer', but its native data structures (such as Ethereum's Merkle Patricia tree) are extremely unfavorable for complex queries and computations. This results in a vast amount of on-chain data being public and transparent, yet difficult to utilize effectively. Through its innovative Verifiable Database architecture, this issue is fundamentally resolved.
The core idea is that the Lagrange network, as an advanced indexer, continuously transforms the raw data on the target chain into a brand new off-chain database optimized for efficient distributed queries and ZK proofs. Most importantly, the entire transformation process generates cryptographic proofs, ensuring that this off-chain database is a 100% faithful mirror of the original on-chain data.
This verifiable database consists of three logical layers, each with its own responsibilities:
Block Database: Manages block headers, transaction receipts, etc., to construct a provable timeline for blockchain history and optimize time series queries.
State Database: Manages global states such as account balances and nonces, optimizing queries for account states at specific points in time.
Storage Database: Handles granular data within smart contracts, optimizing for deep and cross-contract complex queries (such as calculating the global collateral rate of DeFi protocols).
Through this architecture, the Lagrange network driven by $LA transforms chaotic on-chain data into a well-structured, developer-friendly, and cryptographically verifiable high-performance database. This greatly unleashes the potential of on-chain endogenous data, providing a solid foundation for building more complex and powerful dApps.
