ENS domains allows for a readable username that is portable across dApps and blockchains.

To send a crypto payment, you need a long public wallet address composed of a string of digits and letters of the alphabet that looks like gibberish. Moreover, users have a different public address for every cryptocurrency, making it difficult to manage and confusing for crypto beginners.

ENS, short for Ethereum Name Service, aims to make the crypto and decentralized finance space a bit simpler by allowing a user to create a universal nickname for all your public addresses and decentralized websites. Instead of having an unreadable string of keys for each crypto address, you’ll have a single ENS domain, like “Rick.eth,” where you can receive any kind of crypto and NFTs.

ENS aims to become the naming protocol of the decentralized internet by creating portable Web 3.0 usernames that are interoperable across all blockchains and decentralized apps (dApps).

I believe ENS probably has the best chance since it is supported by the largest Crypto Community and these it will be the most popular protocol. Read about 15 ways you can use your .eth address.
