Sui Name Service (SNS) is a decentralized naming protocol built on sui blockchain. It allows users to register and manage human-readable domain names, similar to traditional domain name systems (DNS) used on the internet. However, unlike traditional DNS, SNS is decentralized, meaning that it is not controlled by any single entity.

The main goal of SNS is to create a decentralized naming system that is accessible to everyone, regardless of their location or technical expertise. It aims to provide a simple and user-friendly way for individuals and organizations to create, manage, and own their own domain names. SNS uses smart contracts on the Ethereum blockchain to ensure that domain names are unique and to manage the ownership and transfer of those names.

The SNS system is built on top of the Ethereum blockchain and uses the ENS (Ethereum Name Service) as its underlying infrastructure. ENS is a decentralized naming system for Ethereum addresses and smart contracts, and it allows for the creation of human-readable domain names that can be easily remembered and shared. The ENS system is used by SNS to map domain names to Ethereum addresses, allowing users to interact with smart contracts and decentralized applications (dApps) using their domain name instead of a long and complex Ethereum address.
