Abstract

This demonstration showcases a verifiable multi-chain querying system. The proliferation of blockchain-driven applications has created a demand for on-chain data analysis across multiple blockchains. However, existing solutions face challenges in seamlessly integrating with existing blockchains, maintaining compatible with various database engines, and ensuring the integrity of query results. In response, we develop a blockchain indexing system that utilizes a novel verifiable virtual filesystem (V² FS) for query authentication. Our demonstration focuses on highlighting the key features of our system, including blockchain data indexing, verifiable multi-chain query processing, and the usability and performance of our solution. Additionally, we provide an interactive visualization module to enhance attendees' understanding and insights.
