Web 3.0 is the next generation of the Internet built on decentralized technologies such as blockchain and cryptography. It is born to solve the problems faced by the previous generation of the Internet such as imbalanced distribution of interests, monopoly of platform resources, and leakage of personal privacy. In this survey, we discuss the latest development status of Web 3.0 and the application of emerging AI technologies in it. First, we investigate the current successful practices of Web 3.0 and various components in the current Web 3.0 ecosystem and thus propose the hierarchical architecture of the Web 3.0 ecosystem from the perspective of application scenarios. The architecture we proposed contains four layers: data management, value circulation, ecological governance, and application scenarios. We dive into the current state of development and the main challenges and issues present in each layer. In this context, we find that AI technology will have great potential. We first briefly introduce the role that artificial intelligence technology may play in the development of Web 3.0. Then, we conduct an in-depth analysis of the current application status of artificial intelligence technology in the four layers of Web 3.0 and provide some insights into its potential future development directions.

Web 3.0 是基于区块链和密码学等去中心化技术构建的下一代互联网。它的诞生是为了解决上一代互联网面临的利益分配不平衡、平台资源垄断、个人隐私泄露等问题。在本次调查中，我们讨论了Web 3.0的最新发展状况以及新兴人工智能技术在其中的应用。首先，我们考察了当前Web 3.0的成功实践以及当前Web 3.0生态系统中的各个组件，从而从应用场景的角度提出了Web 3.0生态系统的分层架构。我们提出的架构包含四个层次：数据管理、价值流通、生态治理、应用场景。我们深入探讨当前的发展状况以及每一层中存在的主要挑战和问题。在此背景下，我们发现AI技术将具有巨大的潜力。我们首先简单介绍一下人工智能技术在Web 3.0发展中可能发挥的作用。然后，我们对人工智能技术在Web 3.0的四个层面的应用现状进行了深入分析，并对其未来潜在的发展方向进行了一些见解。
