Ethereum Name Service is a decentralized and open-source naming system that facilitates the translation of human-readable names into machine-readable identifiers such as cryptocurrency addresses, metadata, and content hashes. The project’s operation closely parallels the widely-used Domain Name Service, employing dot-separated names referred to as domains. The ENS domain name itself is an ERC-721 non-fungible token (NFT) containing distinctive machine-readable data, such as wallet addresses.
