The Ethereum Name Service (ENS) is a decentralized domain name system on the Ethereum blockchain that allows users to associate human-readable names with complex Ethereum addresses, simplifying the process of sending and receiving cryptocurrencies and interacting with smart contracts.
ENS enhances the user experience by replacing long and cumbersome addresses with easy-to-remember domain names.
A technological standard or set of guidelines called ERC-20 is used on the Ethereum blockchain to make it easier to create and use fungible tokens. It outlines the fundamental interfaces and functionalities necessary for tokens to work with the Ethereum network, enabling seamless interoperability between various decentralized applications (DApps) and wallets.
On the Ethereum blockchain, a technical standard known as ERC-721 establishes the guidelines for producing and administering non-fungible tokens (NFTs). ERC-721 tokens are different and indivisible, unlike ERC-20 tokens, and they stand for discrete assets with unique features and ownership.
