Gun Database and Indexer for Smart Contract-Enabled Chains

Abstract

Blockchain technology introduces decentralized and immutable ledgers that provide trust and transparency in data management whereas smart contracts can automate business processes. Accessing, and querying data stored on blockchain networks can be challenging due to their complex data structures and limited querying capabilities. In this chapter, we will enhance smart contract-enabled chains' functionality by developing a decentralized database and distributed indexer system capable of executing SQL-like queries on blockchain data. GunDB, a decentralized database known for its robustness and flexibility, enables efficient and simplified data retrieval from blockchain networks. By integrating this database with smart contract-enabled chains, we bridge the gap between blockchain technology and traditional querying methodologies, enabling developers and users to access blockchain data using Structure Query Language-like syntax. Through a carefully designed indexing process, we ensure that the data is efficiently indexed and retrieved with security and immutability characteristics.
