Web3 TLD stands for Web3 Top-Level Domain. A top-level domain (TLD) is the last part of a domain name, such as .com, .org, or .net. In the context of Web3, a Web3 TLD refers to a domain extension specifically designed for decentralized websites and blockchain applications. Examples of Web3 TLDs include .crypto, .zil, and .eth. These TLDs enable the registration of unique and censorship-resistant domain names on blockchain-based systems, empowering users to fully own and control their online presence.
