NFT domain names are blockchain-based addresses that offer a decentralized alternative to traditional domain name systems managed by ICANN, providing owners with complete control over their domains as NFTs on a public blockchain. They serve as easily memorable Web3 wallet addresses and can be purchased and owned rather than rented, managed via smart contracts, and transferred without centralized permission. Two popular providers for NFT domain registration are ENS and Unstoppable Domains, supporting domains like .eth, .crypto, and more. While these systems offer increased user control, they still rely on centralized providers and require manual integration into browsers and applications, presenting a challenge for universal adoption. Despite this, NFT domains can be attached to websites or apps via IPFS, maintaining user control and allowing new decentralized systems to evolve.
