Ethereum Name Service is a decentralized naming system built on the Ethereum network. ENS domains are issued as NFTs in the form of “Gemini.eth”, for example. The NFTs are meant to be human-readable addresses that map to public keys on networks like Ethereum, Bitcoin, and others. Other metadata can be stored within an ENS domain such as a traditional DNS domain like “gemini.com”, Twitter profile, IPFS hashes, and more. There are currently over 550,000 ENS domains owned by over 225,000 ethereum addresses, as of December 17, 2021.
