Abstract
The metaverse is the next technological revolution that will mirror our physical life into a virtual world. In this new world, various data patterns are being generated in large volumes, Avatars can perform various transactions Metaverse's major requirements are data reliability, integrity, security, transparency, and decentral integrity, security, transparency, and decentral are major requirements in Metaverse. Blockchain technology is one of the magic technologies able to optimally implement these requirements in the metaverse. This chapter discusses around why Blockchain is a key player in the metaverse. The chapter discusses the main characteristics of Blockchain and how they can be modeled in the metaverse. In addition, it discusses the differences between fungible and non-fungible tokens (NFTs), and how each token type can be processed using three types of Ethereum Request for Comments (ERC) protocols, ERC-20, ERC-721, and ERC-1155. After that, the chapter presents four real Blockchain applications in the metaverse. finally, the chapter is ended with a set of challenges and open problems around utilizing Blockchain technology in the metaverse.
