Blockchain in the Metaverse

Abstract

This chapter seeks to provide a thorough investigation of blockchain for the metaverse in order to better understand its function in the metaverse. An introduction to blockchain and the metaverse is given first, along with a focus on the reasons for using it for the metaverse. There is discussion of the layers of blockchain and the metaverse. The next section discusses technological aspects of blockchain-based approaches for the metaverse, including data collection, storage, sharing, interoperability, and privacy protection. We outline the technological difficulties of the metaverse for each perspective before highlighting how blockchain can be useful. Additionally, we look into how blockchain will affect important metaverse supporting technologies including the Internet of Things, digital twins, multi-sensory and immersive applications, artificial intelligence, and big data. Finally, some prospective avenues for advancing research, innovation, and development in the direction of blockchain's potential usage in the metaverse are provided.
