智能合约域名是一种 [[blockchain-domain|区块链域名]],其注册、转让、所有权规则和解析逻辑全部由区块链平台(通常是 Ethereum 或 Polygon)上的自执行智能合约编码并执行。智能合约同时充当注册局和注册商,消除了对可信中介的需求。续费政策、解析记录和访问控制等关键属性定义在不可变或可升级的合约代码中,使整个系统对任何人都透明且可审计。[[ens|ENS]] 和 [[unstoppable-domains|Unstoppable Domains]] 等系统均基于智能合约构建。
示例
When alice.eth is registered through the ENS smart contract, the contract automatically records Alice's ownership, stores her resolver settings, and enforces a one-year registration term — all without ENS staff involvement.
