Ethereum Name Service (ENS)

The Ethereum Name Service (ENS) is a decentralized naming system built on the Ethereum blockchain that maps human-readable names (like "alice.eth") to machine-readable identifiers such as wallet addresses, content hashes, and metadata. Similar to how DNS translates domain names to IP addresses, ENS makes it easier to send crypto (instead of copying long hex addresses) and create decentralized websites. ENS names are NFTs that can be bought, sold, and transferred.
