Sui Name Service (SNS) is a decentralized naming system that makes it easier for users to register human-readable names as identifiers for their Ethereum addresses. Unlike traditional DNS systems, which are controlled by centralized authorities, SNS is completely decentralized, making it more resistant to censorship and hacking attempts. SNS is built on the Ethereum Name Service (ENS), but provides a more user-friendly and affordable alternative. Its unique token economy also provides incentives for users to register and use their names, making it a promising new addition to the Ethereum ecosystem.
