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 Labs and GLEIF (the Global Legal Entity Identifier Foundation) are exploring how organizations can link their ENS name to a verifiable Legal Entity Identifier (vLEI), creating one persistent, verifiable identity onchain. GLEIF framed the need with a simple question in a post amplified by ENS — "0x7a3f… received the funds. Which legal entity is that?" — explaining that a signed link between an organization's ENS name and its vLEI would let counterparties and applications verify the legal entity behind an onchain address.
A vLEI is a decentralized, digitally signed credential that lets counterparties verify the identity, authority, and role of people acting on behalf of a legal entity. The exploration is aimed at giving organizations a single way to prove who they are both offchain and onchain via ENS.
ENS shared a walkthrough by @gregskril of enhanced protocol visibility in the ENS Explorer. Instead of abstracting away how ENS works, the tool now surfaces raw onchain data, registry relationships, and OwnedResolvers, letting users inspect the protocol in full — a complement to the Explorer's role as a deep-dive tool for name data onchain.
HL Names has launched .hl.hn, built with ENS, so that ENS can now resolve .hl names and supported apps and wallets can use them. The move extends the universal namespace HL Names is building for the Hyperliquid ecosystem, with ENS powering the underlying naming resolution.
ENS's account shared a walkthrough by @gregskril of the historical audit trail in the ENS Explorer, which now shows the full lifecycle of any ENS name — including ownership changes, transaction details and other historical events. The feature is aimed at letting users verify the provenance of a name with confidence before interacting with it.
The ENS Foundation's Board has formally appointed Aurbelis as its Executive Director, after nearly three years as General Counsel of ENS Labs. The appointment was announced via ENS's official X account.

At ETHOnline by @ETHGlobal, ENS awarded five prizes to projects built on ENSv2 across AI agents, inheritance, tokenized assets and more.
ENS highlighted an integration with Aragon where every Aragon profile comes with a custom .eth name, letting users attach a readable name to the addresses of signers, operators, voters and other roles in a DAO. The announcement frames ENS as the naming layer that makes onchain identities more legible within Aragon's governance products.

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 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.
After nearly three years as General Counsel of ENS Labs, Aurbelis was formally appointed Executive Director of the ENS Foundation by its Board.
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.
