ENS at ETHDenver 2024

ENS is sponsoring multiple events during Lisbon Blockchain Week on July 24-26: - **Onchain Builders Day** - **ETHGlobal Lisbon hackathon** with a $5,000 bounty - **Pragma conference** The naming service will host workshops, deliver a lightning talk, and operate a booth across these events. This marks ENS's presence at one of Europe's major blockchain gatherings, where developers can engage with the protocol and compete for prizes. The sponsorship follows a pattern of ENS supporting developer-focused events in the Ethereum ecosystem.

The **Universal Resolver** acts as a routing system for ENS (Ethereum Name Service), simplifying how name queries are handled across the network. **How it works:** - Functions like a switchboard that automatically routes requests to the correct destination - Users don't need to know where data is stored or the steps to retrieve it - Simply enter a name and get the right answer without technical complexity **Key benefit:** Makes ENS more capable behind the scenes while keeping the user experience simple. Most users won't even know it exists—they'll just get accurate results when resolving names.

**ENS is upgrading its resolver system with ENSv2** The Ethereum Name Service is introducing a Universal Resolver - a single smart contract that can resolve names across multiple environments: - ENSv1 names - ENSv2 names - Layer 2 networks - Offchain names via CCIP-Read **What developers need to know:** Applications using ENS should update their libraries to ensure compatibility with the new Universal Resolver. The system uses CCIP-Read protocol to fetch data from L2s and offchain sources. This consolidation simplifies the resolution process by eliminating the need for separate resolvers for different name types and networks. Developers can find implementation details in the [ENSv2 readiness documentation](https://docs.ens.domains/web/ensv2-readiness/). **Action required:** Review your ENS integration and update libraries to support cross-chain resolution.

ENS has introduced `registerAgentIdentity()`, a new function that provides AI agents with on-chain identity infrastructure. When called, agents receive: - A human-readable ENS subname - An on-chain passport - Cryptographic proof linking the agent to its owner This builds on ENS's evolving role beyond simple name resolution. The system now supports: - **Arbitrary records** that carry an agent's full trust stack - **Identity scoring** (none, registered, discoverable, verified, full) - **Programmable resolvers** that execute logic like token swaps or privacy routing ENS serves as the accountability layer, transforming raw cryptographic keys into verifiable, human-readable identities. One ENS name can hold everything: identity, discoverability, code integrity, and capabilities. The infrastructure makes agents resolvable and accountable while maintaining the flexibility to chain complex actions through custom resolver logic.

A **Trust Resolution Layer (TRL)** has taken first place for establishing verifiable AI agent identity through ENS. The system combines multiple components: - World ID verification - ENSIP-25 agent registration standard - ENSIP-26 context records - Novel AIP manifest system These elements work together to create a **progressive 5-tier trust scoring system** for autonomous agents. This infrastructure addresses a critical need as AI agents increasingly sign transactions, hold assets, and interact with blockchain protocols. The TRL builds on ENSIP-25, which introduced standardized verification that an onchain-registered AI agent is genuinely associated with an ENS name. The solution provides essential identity infrastructure for the growing ecosystem of autonomous agents operating in web3.
