ENS (Ethereum Name Service)
Decentralized naming system — converts 0x address into readable 'name.eth'.
ENS (Ethereum Name Service) is a decentralized naming system built on the Ethereum blockchain that maps human-readable names (vitalik.eth) to Ethereum addresses, IPFS content and other resources.
How it works:
•Buy ENS name on app.ens.domains (annual renewal)
•Set it to point to your Ethereum address
•Anyone can send you ETH or tokens to "name.eth" without copy-pasting address
•ENS is an ERC-721 NFT — you can sell it on OpenSea
Pricing:
•3 characters: $640/year
•4 characters: $160/year
•5+ characters: $5/year
Reverse resolution:
•Applications display "vitalik.eth" instead of "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
Usage beyond Ethereum:
•ENS .eth domains used as Web3 identity on Twitter, Discord
•Lens Protocol, Farcaster — Web3 social networks recognize ENS
ENS token: governance token for ENS DAO.
