Ethereum Name Service
The Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain.
ENS’s job is to map human-readable names like ‘alice.eth’ to machine-readable identifiers such as Ethereum addresses, other cryptocurrency addresses, content hashes, and metadata. ENS also supports ‘reverse resolution’, making it possible to associate metadata such as canonical names or interface descriptions with Ethereum addresses.
ENS has similar goals to DNS, the Internet’s Domain Name Service, but has significantly different architecture due to the capabilities and constraints provided by the Ethereum blockchain. Like DNS, ENS operates on a system of dot-separated hierarchical names called domains, with the owner of a domain having full control over subdomains.
Top-level domains, like ‘.eth’ and ‘.test’, are owned by smart contracts called registrars, which specify rules governing the allocation of their subdomains. Anyone may, by following the rules imposed by these registrar contracts, obtain ownership of a domain for their own use. ENS also supports importing in DNS names already owned by the user for use on ENS.

Ambire Adds ENS Address Change Detection for Safer Transactions
Mon 27th Jul 2026
**Ambire** has introduced a new security feature that alerts users when an ENS (Ethereum Name Service) address has changed since their last interaction.
**Key Features:**
- Notifies users of address changes associated with ENS names
- Helps prevent sending funds to unintended recipients
- Adds an extra layer of security for ENS-based transactions
This update addresses a potential security risk where ENS name ownership could transfer to a different address, potentially leading to misdirected transactions. The feature provides users with confidence when sending value through the platform.

ENS DAO Activates New Eight-Member Security Council with Two-Year Veto Authority
Thu 23rd Jul 2026
ENS DAO has approved a new Security Council that will operate for the next two years. The council consists of eight members with authority to cancel malicious proposals after they pass but before execution.
**Key Details:**
- Operates through a 5-of-8 multisig structure
- Requires at least five members to agree before canceling any proposal
- Authority expires after two years unless extended by ENS DAO vote
- Designed as a safeguard against malicious governance proposals
The activation proposal has now passed, establishing this oversight mechanism for the Ethereum Name Service's decentralized governance.

The Ethereum Name Service has appointed eight new council members:
- **Nick Johnson** (@nicksdjohnson)
- **Hudson Jameson** (@hudsonjameson)
- **Pablo Sabbatella** (@PabloSabbatella)
- **Colton Liberacki** (@Coltron_eth)
- **Kevin Gaspar** (@ValidatorETH)
- **Alex Van de Sande** (@avsa)
- **Griff Green** (@griffgreen)
- **Alex Netto** (@alextnetto)
The announcement marks a governance expansion for ENS, the Ethereum-based naming system that maps human-readable names to blockchain addresses.
ENSv2 Launches Universal Resolver for Cross-Chain Name Resolution
Thu 21st May 2026
**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 Launches registerAgentIdentity() for On-Chain Agent Verification
Fri 24th Apr 2026
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.
🏆 Trust Resolution Layer Wins First Place for Verifiable Agent Identity
Fri 24th Apr 2026
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.
ENS Releases Alpha Log #5 with Reliability and Usability Updates
Thu 2nd Apr 2026
The Ethereum Name Service has published its fifth alpha development log for ENSv2, detailing continued improvements to the App and Explorer on the Sepolia testnet.
**Key Updates:**
- Focus on reliability, flexibility, and overall usability enhancements
- Builds on previous fixes including transaction modal layouts and Fuses page improvements
- Ongoing polish to search functionality, profiles, notifications, and name management features
The ENSv2 testing phase continues on Sepolia as the team iterates on the user experience before mainnet deployment. More updates are expected in upcoming alpha logs.
🚀 Faster... Smoother... Better
Thu 2nd Apr 2026
The ENS App just got a performance boost. Profile data now loads faster thanks to optimized record fetching, making name management feel noticeably smoother.
**What changed:**
- Profile records are fetched more efficiently
- Viewing name details is quicker
- Managing profiles feels more responsive
This follows recent updates that added Layer 1 primary name management and streamlined subname creation with address pre-population.

ENS App Now Includes Built-in Expiration Notifications
Fri 6th Feb 2026
The ENS Manager app has introduced a highly anticipated feature: **built-in expiration notifications**.
**Key Features:**
- Set up reminders through multiple channels: email, Telegram, or browser notifications
- Never lose your ENS domain to accidental expiry
- Notifications work directly within the app at [app.ens.domains](http://app.ens.domains)
**Additional Context:**
This builds on existing ENS Manager features, including the ability to register and extend names by selecting exact expiration dates for more precise domain control.
The notification system addresses a common pain point for ENS users who may forget renewal dates and risk losing valuable domain names.
ENS Prepares for v2 Launch with Universal Resolver Updates
Mon 15th Dec 2025
**ENS is gearing up for its v2 launch** by requiring developers to update their libraries and applications.
Key requirements for ENSv2 readiness:
- Update ENS libraries to latest versions
- Ensure apps resolve names via **CCIP-Read protocol**
- Verify **L2 compatibility** for name resolution
- Implement Universal Resolver support
The Universal Resolver serves as the foundation for ENSv2, enabling cross-chain name resolution and improved functionality.
**Why this matters:**
ENSv2 represents a significant upgrade to Ethereum's naming infrastructure, expanding beyond simple address mapping to comprehensive web3 identity management.
Developers should review the [ENSv2 readiness documentation](https://docs.ens.domains/web/ensv2-readiness/) and test their applications now to ensure seamless transition.
*Action needed: Update your ENS integrations before the v2 launch to avoid service disruptions.*
