Swaroop Hegde I PowerLoom Announcement and Scaling Trust | Pragma Waterloo

Mon, Oct 2, 2023, 12:00 AM

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. 00:00 Intro to PowerLoom and the demo 00:40 Swaroop’s journey from Matic to PowerLoom 01:48 Early scale challenges and on-chain data limits 02:49 The origin of PowerLoom and snapshot concept 03:23 How PowerLoom works: snapshots and proofs 04:24 Use case: Uniswap analytics without querying 05:21 Launching a PowerLoom node with GitHub Codespaces 07:04 Testnet access and current participation rules 08:01 Tracking Uniswap pairs and epochs 09:35 How consensus finalizes snapshots 10:17 Viewing snapshots and verifying on IPFS 11:23 Node successfully submits snapshot data 12:05 Live demo success and story of the original hackathon 13:42 Why decentralization and data integrity matter 14:46 How PowerLoom ensures trusted data availability 15:54 Comparing PowerLoom to The Graph 16:56 Latency tradeoffs and precomputation 17:27 What PowerLoom enables for new Web3 apps 18:30 Final thoughts and invitation to build with PowerLoom _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇨🇦 *Pragma Waterloo* The now third edition of Pragma kicked off with a curated series of high-quality talks that sparked thought and discussion among attendees as they were storming into the Auditorium of the CIGI Building.
