Query: Fusing Blockchain and AI with Metaverse: A Survey   Metaverse as the latest buzzword has attracted great attention from both
industry and academia. Metaverse seamlessly integrates the real world with the
virtual world and allows avatars to carry out rich activities including
creation, display, entertainment, social networking, and trading. Thus, it is
promising to build an exciting digital world and to transform a better physical
world through the exploration of the metaverse. In this survey, we dive into
the metaverse by discussing how Blockchain and Artificial Intelligence (AI)
fuse with it through investigating the state-of-the-art studies across the
metaverse components, digital currencies, AI applications in the virtual world,
and blockchain-empowered technologies. Further exploitation and
interdisciplinary research on the fusion of AI and Blockchain towards metaverse
will definitely require collaboration from both academia and industries. We
wish that our survey can help researchers, engineers, and educators build an
open, fair, and rational future metaverse.
