Ethereum Name Service

ENS profiles get personal: designer walks through App theming

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.

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.
