In this workshop at ETHGlobal New York 2026, Greg Skril from ENS Labs presents ENS as a source of identity for apps, agents, and more. He starts with the basics: the Ethereum Name Service is a decentralized, permissionless naming protocol that lives on Ethereum but scales to the entire internet, most simply turning complex hex addresses into human-readable names (his address becomes gregskril.eth). He frames ENS as a user experience protocol, showing how sending five dollars to a name is far easier than copying a hex address, and how ENS has evolved from a username into a full profile with an avatar, banner, and description that replaces the anonymous gray circle and truncated address most apps show. His first conclusion: users of crypto-powered experiences should never have to interact with a hex address, and anywhere an app reads or writes one, it should support ENS names. He explains how it works through forward resolution (name to data) and reverse resolution (address to name), which combine into a primary name set via reverse registrars on six chains, and can be configured on behalf of another user with their signature. Greg then positions ENS as a universal pointer to anything on the internet, not just addresses: naming smart contracts for clearer block explorer history, decentralized registries (like a hackathon NPM clone where each package is an ENS name with text-record metadata pointing to decentralized content), storing credentials or AI agent metadata via text records (with a spec, ENSIP-26, for agents), and decentralized websites (like Vitalik's IPFS-hosted blog that survives a Cloudflare outage). He covers subnames, which are full ENS names usable for clean hierarchy and cheap free onboarding (buy projectname.eth, give users free subnames), highlighting the Durin tool at durin.dev for deploying subname contracts to an L2 linked to L1. He previews ENS V2 (live on Sepolia) with a cleaner registry design and fine-grained permissions enabling org structures, and an ENS CLI as the easiest way to teach agents to use ENS. He lays out a record $20,000 in prizes across an AI agents track, a creative use track (citing a privacy solution that resolves a name to different addresses per sender), a $6,000 pool prize, and a $4,000 continuity track, then closes with Q&A on reassigning and revoking subdomains, gas costs, off-chain names, and how subnames compare to second-level domains. 00:00 Introduction 00:11 What Is ENS 00:42 Turning Hex Addresses Into Names 01:08 ENS as a User Experience Protocol 01:35 From Username to Full Profile 02:01 Why a Profile Beats a Gray Circle 02:42 ENS Used in the Wild 03:26 Reading and Writing Data With Names 03:56 Why Users Should Never See a Hex Address 04:21 How It Works: Forward and Reverse Resolution 04:52 Primary Names and Reverse Registrars 05:43 Setting a Name on Behalf of Another User 05:59 ENS as a Universal Pointer 06:20 A Decentralized NPM Registry Example 06:46 Storing Credentials and Agent Metadata 07:06 Text Records and ENSIP-26 07:31 Decentralized Websites Like Vitalik's Blog 08:44 Naming Smart Contracts 09:29 Subnames and Clean Hierarchy 10:19 Free Subnames for Onboarding Users 10:41 The Durin Tool for Subnames 11:05 Introducing ENS V2 11:36 New Registry Design and Permissions 11:58 Org Structures With Fine-Grained Access 12:23 A Preview of the ENS CLI 12:49 The $20,000 in Prizes 13:20 The Build From Scratch Tracks 13:39 The AI Agents Track 14:09 The Creative Use Track 14:37 A Privacy Solution Built on ENS 14:57 The Pool Prize 15:20 The Continuity Track 16:02 Key Takeaways 16:30 Where to Get Help 16:53 Q&A: Reassigning Subdomains 18:29 Q&A: Limits on Subdomains and Gas Fees 19:50 Q&A: Preventing Revocation of User Subdomains 21:14 Q&A: Subnames vs Second-Level Domains 22:19 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHGlobal New York 2026* This workshop is specifically for ETHGlobal New York 2026, a 3-day hackathon held June 12-14 at the Metropolitan Pavilion, 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!

In this talk, Brantly Millegan from ETHID shares lessons from 10 years working on the Ethereum identity stack. He opens with his own onchain profile and ENS name, brantly.eth, encouraging everyone to get a name at ens.domains. He traces the story back 50 years to the 1970s invention of public key cryptography, which for the first time let people encrypt messages without exchanging a secret key ahead of time. The US government classified it as too powerful, until Phil Zimmerman and the cypherpunks successfully lobbied in the 1990s to make it legal for public use, enabling e-commerce and HTTPS. The cypherpunks saw public key cryptography as the basis for digital identity, but consumer versions like PGP never broke out because appeals to privacy and liberty alone do not motivate enough people without financial incentive. Brantly explains that Bitcoin (2008) and Ethereum (2015) changed this by using public key cryptography for wallets, accomplishing through economic incentives what cypherpunks could not through appeals to values: the widespread adoption of private keys and a flourishing wallet industry. Vitalik named identity as a use case in the 2014 Ethereum white paper, but many early identity projects failed because they treated identity as a single app when it is really 20 hard problems at once, and because building in a decentralized way is far harder than centralized. The breakthrough was Ethereum Name Service, which started in 2016 and launched in 2017 modeled after DNS for decentralized websites, then crypto payments. In 2021, while on the team, Brantly realized ENS was accidentally your crypto username and profile, the meta use case underlying all the others. He credits ENS's success to not competing directly with DNS, great engineering, and long time horizons, making it extremely Lindy after nine plus years. He covers Sign in with Ethereum (EIP-4361) as a decentralized user-controlled single sign on, the Ethereum Follow Protocol as an onchain social graph, and Ethereum Identity Kit as a React component library. He closes with his core thesis: Ethereum identity is not a single app but the sum of information and relationships across decentralized protocols and open standards, unbundled into smallest viable parts so each can stand, fall, improve, or be replaced independently, making the whole stack more resilient. 00:00 Introduction 00:35 Brantly's Onchain Profile and ENS Name 00:47 Going Back 50 Years to Public Key Cryptography 01:09 What Public Key Cryptography Is 01:38 Why the US Government Classified It 01:52 The Cypherpunks Make It Legal in the 1990s 02:07 Why It Powers E-Commerce and HTTPS 02:28 Cryptography as the Basis for Digital Identity 02:48 Why PGP Never Broke Out 03:14 Bitcoin, Namecoin, and Early Naming 03:33 Identity in the 2014 Ethereum White Paper 04:06 How Crypto Spread Private Keys at Scale 04:38 Why Wallets Keep Getting Better 05:12 Why Early Identity Projects Failed 05:37 Why Decentralized Is Harder Than Centralized 06:12 The Ethereum Name Service Breakthrough 06:30 Realizing ENS Was a Username and Profile 06:59 Why the Username Is the Meta Use Case 07:15 Why ENS Has Succeeded Where Others Failed 07:39 Not Competing Directly With DNS 08:04 Great Engineering and Long Time Horizons 08:36 Why ENS Is Extremely Lindy 08:58 Accidentally Solving Single Sign On 09:26 The Vision of a Decentralized Account for the Internet 09:44 Sign in with Ethereum and EIP-4361 10:07 The Ethereum Follow Protocol Social Graph 10:36 Other Parts of the Identity Stack 10:58 Ethereum Identity Kit for Developers 11:18 What Ethereum Identity Really Is 11:39 Why the Stack Is Decentralized, Not Vertically Integrated 11:58 Why Each Part Can Stand or Fall on Its Own 12:17 Why This Makes the Stack Resilient 12:40 Why We Should Not Take This for Granted 13:06 The Hard Work Behind the Stack Today 13:25 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHConf 2026* ETHConf is a 3 day event for founders, industry leaders, and builders who are excited about the possibilities of building on top of Ethereum.

In this workshop, Greg Skril from ENS Labs introduces the Ethereum Name Service for Open Agents hackathon participants and explores how ENS serves as identity infrastructure for apps, AI agents, and beyond. He covers ENS's core function — turning hex addresses into human-readable names — and demonstrates how a name like greg.eth becomes a full Web3 portable profile with avatars, multi-chain addresses, social accounts, and arbitrary text records. Greg emphasizes that ENS is fundamentally a user experience protocol: anywhere an app reads or writes a hex address, it should use an ENS name instead. Greg dives into how ENS works through forward and reverse resolution combining to form primary names across chains, then walks through agent-specific use cases: subname namespaces (agent.work.eth, travel.agent.work.eth), ENSIP-25 verification with the ERC-7804 agent registry, and storing agent metadata in text records. He introduces interoperable chain names through "on.eth" (the only two-character ENS name), allowing addresses like vitalik@base.on.eth for cross-chain resolution. He also covers building decentralized websites with Omnipin and IPFS, naming smart contracts, and using Durin for issuing subdomains on any EVM chain. The hackathon offers two tracks with three winners each ($500/$750/$1,250): best ENS integration for AI agents and most creative use of ENS. 00:00 Introduction 00:39 What Is ENS 01:33 ENS as a User Experience Protocol 02:21 ENS Profiles and Portable Identity 03:42 Connect Wallet UX With and Without ENS 04:58 Examples in the Wild: Snapshot and Matcha 05:24 ENS for Transaction History and Sending Assets 07:11 Users Should Never See Hex Addresses 07:41 How ENS Works: Forward and Reverse Resolution 09:04 Primary Names and Reverse Registrars 09:56 Using ENS for AI Agents 10:29 Agent Namespaces and Subname Hierarchies 11:51 Agent Metadata in Text Records 12:15 ENSIP-25: Verification with ERC-7804 Registry 13:23 Names for Chains: Interoperable Names with on.eth 14:51 Decentralized Websites with Omnipin and IPFS 16:37 Naming Smart Contracts and Smart Accounts 17:32 Subnames for Onboarding Users 18:00 Durin: Issuing Subdomains on Any EVM Chain 18:53 Custom Text Records as Decentralized Storage 19:24 Building Blocks for Different App Types 21:46 ENS Improves Existing Apps 22:39 Hackathon Prize Tracks 23:30 Q&A: Encrypted Data and Fluid Key Privacy 25:26 Q&A: Killer Use Cases and Verification 27:19 Q&A: Custom Metadata and Text Records 28:36 Q&A: CCIP Read and Decentralized Websites 31:16 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🤖 *Open Agents 2026* This workshop is part of Open Agents 2026, an online hackathon held from April 24 to May 6.

Luka Kropec

Conflux - Web3 UX Unconference · Nov 16, 2023

No description The video features Luca discussing the importance of translating Ethereum-related content to make it accessible to non-English speakers worldwide. He highlights that only a small percentage of the global population speaks English natively, and with Ethereum's impact growing in developing countries, removing language barriers is crucial. Machine translations are not sufficient due to the technical nature and constant evolution of blockchain technology. The literal translation of terms like "roll up" or "staking" can be misleading without proper context. Therefore, human translations are needed for clarity and accuracy. Luca mentions Ethereum.org's commitment to multilingual content, with the website now available in 62 languages and over 3,600 translated pages. This effort has led to a significant increase in non-English page views. The talk also introduces a new initiative to translate images and infographics using a plugin that integrates with Figma, aiding visual learners. He invites others who are interested in translating their content or improving their translation efforts to reach out for support or advice. Luca then addresses questions about the unique challenges of translating UX elements and whether certain technical terms should be translated or not. He suggests maintaining a glossary of terms for consistency across translations and mentions the possibility of creating standalone versions of websites for certain languages. In conclusion, Luca emphasizes the importance of making
