## Description

Join Swaroop Hegde, co-founder of PowerLoom, as he unveils a groundbreaking approach to scalable, verifiable on-chain data aggregation using snapshots, cryptographic proofs, and decentralized storage systems like IPFS and Filecoin.

In this live demo at Pragma Waterloo, Swaroop showcases how PowerLoom nodes can be easily deployed in minutes with no gas required, transforming how we think about data availability, composability, trustlessness, and the future of Web3 infrastructure. Learn how PowerLoom addresses limitations in traditional query-driven indexing by enabling precomputed, verifiable snapshots across chains, and how this powers composable applications and use cases like Uniswap analytics, DAO operations, and more.
