ENS Identity in Your Apps I Greg Skrill

Thu, Oct 2, 2025, 12:00 AM

Greg Skrill from ENS Labs presents on integrating ENS (Ethereum Name Service) identity into applications. ENS is a decentralized, permissionless naming protocol on Ethereum that converts complex hex addresses into human-readable names (e.g., gregskril.eth), improving user experience across web3 apps. ENS acts as a portable web3 profile, supporting metadata like avatars and bios via text records. He explains forward and reverse resolution, primary names, and recent support for L2s (Arbitrum, Base, OP Mainnet, Linea, Scroll), enabling cheaper, more flexible identity management. Subdomains and DNS integration allow for hierarchical and interoperable naming (e.g., greg.project.eth, gregskril.com). Greg highlights creative ENS use cases like Fluid Key, which enhances privacy by dynamically resolving names to different addresses. He encourages developers to replace hex addresses with ENS names, leverage metadata, and explore the ENS docs for tools and resources. Q&A covers latency, subdomains, metadata storage, Python support, identity proofs (e.g., zero-knowledge), and wallet integrations. 00:00 Introduction 00:34 What is ENS? 00:59 Human-Readable Names vs Hex Addresses 01:52 ENS as a Portable Web3 Profile 03:37 Improving User Experience with ENS 04:54 ENS as a Global Username System 05:35 Technical Overview: Forward & Reverse Resolution 06:55 ENS on L2s and Primary Names 08:00 Summary and Developer Guidance 08:23 ENS Tools, Subdomains, and Resources 09:16 ENS Hackathon Prizes and Use Cases 10:05 Creative ENS Applications: Fluid Key 10:56 Q&A: Fluid Key, DNS Integration 12:45 Q&A: Latency, Subdomains, Metadata 16:13 Q&A: Metadata, Arbitrary Data, Python Support 17:29 Q&A: Linking ENS to Emails/Phone Numbers 18:50 Q&A: Identity Proofs and Zero-Knowledge 19:53 Q&A: Smart Wallets and ENS Integration 21:42 Conclusion and Further Questions _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇺🇸 *ETHGlobal New York* This workshop is specifically for ETHGlobal New York, a 3-day hackathon held August 15-17, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
