以太坊名称服务（ENS）

Ethereum Name Service (ENS) is a decentralized naming protocol built on the Ethereum blockchain that simplifies blockchain interactions by replacing long, complex hexadecimal addresses with human-readable names ending in .eth. ENS names serve as universal identifiers that can be used across wallets, dapps, and websites, enabling users to send and receive crypto assets, sign in to services, and maintain a consistent digital identity across Web3 and the broader internet. ENS aims to make blockchain technology more accessible and user-friendly by eliminating the need to manage complicated addresses.

ENS provides a suite of smart contracts and resolvers that allow developers to integrate ENS into their applications easily. It supports features such as reverse resolution, text records for metadata, avatars, and cross-chain resolution capabilities. The protocol is governed by the ENS DAO, a community-driven organization that oversees upgrades and ecosystem development. ENS has broad adoption with over 1.3 million registered names and more than 600 integrations, including partnerships with Coinbase Wallet, Rainbow Wallet, Brave Browser, GoDaddy, Etherscan, and Uniswap.

What sets ENS apart is its decentralized governance model, full user ownership of names, and extensibility through resolvers that enable storing arbitrary data linked to a name. ENS names are uncensorable and irrevocable, providing true digital ownership. Developers can get started by using the ENS app to register names or by integrating ENS resolution libraries and smart contracts documented extensively in the ENS developer docs. ENS also supports advanced use cases like Sign-In with Ethereum (SIWE) and ENSv2 upgrades for enhanced functionality.
