What Is Ethereum Name Service (ENS)? 

ENS is a decentralized naming protocol built on the Ethereum blockchain. 

At its core, it maps machine-readable identifiers—such as Ethereum wallet addresses or IPFS content hashes—to human-readable names like “alice.eth.”

ENS makes it easier for users to interact with blockchain resources. Instead of pasting long complex Ethereum addresses users can input simple ENS names.
