Abstract:     Metaverse is a digital space resulted from the integration of existing technologies such as big data, artificial intelligence, 5G and AR/VR. Traditional Law 1.0 has a rule system that regulates facts to be specified. Law 2.0 contains new rules and regulatory framework, thus directly serving relevant policies. Law 3.0 recognizes that new technologies are also regulatory tools. The influence of technology on legal system began with“system theory”and flourished in cyberlaw. However, the AI rule of law is different from the Internet rule of law in that users live and interact with digital people, and the algorithmic entities share no hierarchical structure except consensus mechanism (code). Law 3.0 does not mean the end of Law 2.0 or Law 1.0. Instead, it reinterprets regulatory responsibility as the core and sets up a“triple license”for the use of technical tools. The latest AI legislative practice home and abroad embodies the spirit of Law 3.0.

Key words: Metaverse, Law 3.0, decentralized rule of law, algorithm entity, unwritten law
