# What is EDNS?

EDNS is a name and lookup service built on the Polygon blockchain, a layer-2 scaling solution for Ethereum, and it's compatible with Ethereum allowing crypto users to translate their machine-readable addresses to human-readable addresses. It provides a Decentralized Domain Naming Service for Web3.0-related demands, including NFT, Cryptocurrency Wallet, Web hosting, DeFi ID, and GameFi ID in the Digital world. Moreover, to serve a wider range of users, EDNS will expand to support more blockchains, and ultimately become a multichain platform.
