W3 Name Service (W3NS) Protocol is a distributed, open, and scalable naming system based on the Ethereum Virtual Machine blockchain. W3UP Domains stands out from other domain service providers by ensuring 100% on-chain storage of metadata and domain names. This approach eliminates the risks associated with centralized server storage, such as data modification or deletion, and ensures the perpetual existence of domain information on the blockchain. Additionally, W3UP Domains allows users to store additional on-chain data, such as homepage URLs, Twitter handles, emails, and more, providing enhanced security and flexibility.
