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.

ENS published an explainer on how ENSv2 makes the hierarchy of names explicit onchain. Instead of every name living in one flat registry, each name can define its own registry, resolver, and rules for the namespace below it. The post points to more detail on the ENSv2 architecture as the revamped naming layer moves toward mainnet.
ENS's X account shared Aave's announcement that AI tools and agents can now interact with Aave through its official MCP server, which can be connected to Claude, ChatGPT, or any MCP-compatible assistant. The retweet signals support for standards that let AI agents act onchain.
The ENS team shared a walkthrough by @gregskril of the new proactive notifications in the ENS App, letting users track expiry dates, catch renewal reminders, and renew a name before it lapses. The feature addresses a long-requested pain point for name holders and is part of the revamped ENS App being built around the ENSv2 registry.
ENS's account shared an announcement from namespace_eth introducing ENS Forge, an open-source typed SDK that expands the capabilities of ENSjs. The tool is aimed at improving the developer experience around the ENS onchain naming layer.
ENS's official account shared a walkthrough by @gregskril of the one-click registration flow now in the ENS App, from picking a name through payment options to an instantly built profile. The demo highlights how the new App compresses what was previously a multi-step process into a single click, part of the revamped ENS App UI being built around the ENSv2 registry.
ENS's official X account retweeted dotlocker's announcement that .locker identity names are now available on Ethereum, positioning the name service around portable identity that doesn't depend on any single platform. The short announcement points to onboarding details for the newly launched service; the exact relationship between .locker and ENS names was not specified in the post.
OpenZeppelin has integrated ENS into its developer tools, giving builders access to the onchain naming layer inside both the OpenZeppelin UI Builder and the Role Manager. The integration positions ENS names as a standard building block for apps built on OpenZeppelin's platform, letting developers use readable .eth names rather than raw addresses in the interfaces they create.
Box (boxdomains) launched BoxV2, its next-generation .box name service, announcing that users can now register a .box name for $50/year, paid via credit card or crypto. The launch was promoted through a retweet on ENS's official X account, though details on what changed in V2 and how it relates to ENS names were not specified in the announcement.
Latest on ENS App and Explorer beta: ENS designer Ali walked through the revamped profile features, showing how themes, records and smaller details shape how a name appears across the ecosystem. The walkthrough highlights the personalization options being tested in the Sepolia beta, alongside renewals, flexible expiry dates, primary-name shortcuts and notifications. The beta runs on Sepolia and exercises the ENSv2 registry plus the upgrade flow for eligible .eth names before mainnet.
Lighter has integrated ENS in a partnership announced via Lighter and ENS on X. Users can now use their readable ENS name to simplify the withdrawal experience on the platform rather than entering a raw wallet address.
ENS dropped plans for its Namechain Layer 2 rollup and said it will deploy the ENSv2 upgrade exclusively on Ethereum mainnet, citing dramatically lower gas costs and a shift in Ethereum's L1 scaling philosophy.
ENS Labs proposed ENSv2, a plan to expand and rearchitect the ENS protocol onto Layer 2 networks, citing lower gas costs, a more flexible hierarchical registry, and improved multi-chain interoperability.
A governance proposal to remove ENS Foundation director Brantly Millegan over resurfaced anti-LGBTQ tweets failed, and he remained a director and voted in the decision himself.
ENS introduced its $ENS governance token, airdropping 25 million tokens to .eth name holders and establishing the ENS DAO to govern the protocol and its treasury.
ENS upgraded to a permanent registrar contract, ending the Vickrey auction in favor of instant registration for .eth domains and converting them into ERC-721 non-fungible tokens with annual renewal fees.
ENS launched by Nick Johnson and Alex Van de Sande of the Ethereum Foundation on May 4, 2017, initially offering registration of .eth names seven characters or longer via an auction-based registrar to limit squatting.
