It has a strong ecosystem build by global communities. .bit is a blockchain-based, open source, decentralized cross-chain account system that provides a worldwide unique naming system with a .bit suffix that can be used in different scenarios, such as cryptocurrency transfer, domain name resolution, identity authentication, etc. .bit is the first decentralized account system with broad compatibility, allowing users to register and manage their .bit accounts with any public chain address or even email.
