The ENS, or Ethereum Name Service, functions as a decentralized domain name system for the Ethereum blockchain. It allows users to register human-readable names (like "yourname.eth") that can be linked to Ethereum addresses, making transactions simpler and more user-friendly. ENS enhances usability by replacing complex hexadecimal addresses with easily recognizable names, facilitating easier interaction with decentralized applications and the broader Ethereum ecosystem.
