ENS (Ethereum Name Service) provides a decentralized, human-readable naming system for blockchain addresses and digital identities, functioning as a Web3 counterpart to DNS. Simon Emanuel Schmid introduced ENS’s role in turning unreadable hex addresses into user-friendly names, which can map to multiple chain addresses, profiles, and even imported DNS domains. He detailed forward and reverse resolution—the former mapping names to addresses, the latter linking addresses back to names—and explained how both complete a “primary name.” A new L2 Primary Name feature enables setting mainnet identities configured on L2s like Base. The talk emphasized using ENS in hackathon projects to simplify UX, manage decentralized identities, and integrate the Universal Resolver and CCIP-Read for on-chain/off-chain lookups. Nischal Sharma demonstrated how naming smart contracts enhances trust and prevents spoofing by labeling verified contracts on-chain using ENS—transforming hex addresses like “0x…” into recognizable names such as router.uniswap.eth. His tool, Enscribe, makes naming simple via a UI and supports L2 primary names. Harpreet Singh followed with a deep dive on subnames, explaining L1 (fully on-chain), L2 (cheap and NFT-backed), and off-chain (centralized) subnames. He covered EIP-3668 (CCIP-Read) powering these subnames and tools like Namespace SDK, which enables token-gating, whitelisting, and reserved ENS names on Base and Optimism. The session closed with an invitation to use the Notion hacker pack and build innovative ENS-powered identity integrations. 00:02 Intro & ENS Hackathon Prizes 01:53 What is ENS & how it works 03:39 Forward vs Reverse Resolution 04:33 L2 Primary Names & Cross-Chain Addresses 05:22 ENS Profiles & Multi-Chain Identity 07:03 Universal Resolver & CCIP-Read 09:06 Building with ENS & Hackathon Resources 09:29 Smart Contract Naming (Nischal Sharma) 11:21 Forward & Reverse Resolution in Contracts 12:52 Enscribe UI & L2 Naming 14:45 Subnames Overview (Harpreet Singh) 15:53 L1, L2 & Off-Chain Subnames 17:32 EIP-3668 & CCIP-Read Flow 18:31 Namespace SDK & L2 Subname Issuance 20:03 Wrap-up & Developer Resources _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *ETHGlobal New Delhi* This workshop is specifically for ETHGlobal New Delhi, a 3-day hackathon held September 19-21 at the India International Convention & Expo Centre, 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!

Conflux - Web3 UX Unconference · Nov 16, 2023

No description The video features an opening speech from a conference in Istanbul addressing the UX community. Despite regional challenges and the absence of some colleagues, the speaker appreciates attendees' presence at DevConnect and encourages them to enjoy the additional activities available, including Turkish ice cream and coffee. The speech explains that the UXLand conference is an "un-conference," where participants create the event by discussing topics of interest to them. The conference has no sponsors or volunteers but is supported by the Ethereum Foundation and DevConnect. The speaker emphasizes that the success of the event depends on attendee participation and stresses that it's a collaborative environment rather than a platform for promoting individual projects. Attendees represent various professional backgrounds, with product development, engineering, and design being prominent. Key topics for discussion include account extraction, user onboarding, Web3 design principles, and general adoption within the ecosystem. Working groups will form to delve deeper into these areas in a collaborative setting with provided tools like FigJam for documentation. The speaker also mentions a goal of creating memorable ways (memes) to communicate complex UX concepts outside of the conference to foster broader understanding and excitement. An example given is "4337," which has gained attention despite many not fully understanding it. The video outlines rules for speakers, including strict time limits,
