Modern Blockchain Indexing I Denham Preen

Sun, Nov 2, 2025, 12:00 AM

Denham Preen, co-founder of Envio, presents on modern blockchain indexing at scale, emphasizing the need for advanced tools as blockchain transaction throughput surges from Ethereum’s 15 TPS to new chains like Monad and Sonic reaching up to 400,000 TPS. He outlines three pillars of modern indexing: performance (handling massive event volumes, e.g., 80M events in 9 hours), multi-chain support (indexing across 20+ networks, simplifying DevOps), and flexibility (end-to-end backend integration, async event handling, custom notifications, and database compatibility). Envio’s stack includes Hypersync (Rust-based, high-performance data engine) and Hyperindex (developer-friendly, multi-chain framework). Real-world use cases include headless block explorers, revoke.cash integrations, streaming APIs, real-time analytics, arbitrage dashboards, and oracle indexing. Modern indexing enables scalable, flexible, and multi-chain DApp development, crucial for the next generation of blockchain applications. 00:00 Introduction 01:00 About Denham Preen and Envio 02:15 What is Blockchain Indexing? 03:03 Evolution of Blockchain Throughput 04:18 The Need for Modern Indexing 04:53 Three Pillars: Performance, Multi-chain, Flexibility 05:42 Performance Case Study: Metry 07:01 Multi-chain Indexing: Sablier & Pimlico 08:26 Flexibility in Indexing: Monad Clip Example 09:18 Advanced Use Cases for Flexible Indexers 10:05 Envio Stack: Hypersync & Hyperindex 11:15 Hypersync: Rust-based Performance Engine 12:09 Indexers as Application Tools 12:29 Practical Examples & Demos 13:23 Security & Approval Tools: revoke.cash, Snub 13:55 Big Data & Real-time Analytics 14:17 Uniswap v4 Analytics 15:09 Arbitrage Dashboards & Oracle Wars 15:58 Scaling to Visa-level Throughput 16:19 Community Feedback & Recap 16:44 Closing & Contact Info _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *Pragma New Delhi* Pragma New Delhi 2025 was held on September 25th at the JW Marriott Hotel in Aerocity New Delhi and was an in-person summit for builders and leaders in the web3 ecosystem.
