What is Non-Fungible Token (NFT)

The term metaverse was first used in the novel 'Snow Crash.' However, it has come into people's lives with the development of 3D design and visual techniques, machine computations, blockchain, and the internet. Companies and communities worldwide are launching their metaverse platform with diverse functions like trading, gaming, and socialization. The virtual spaces are designed, and virtual buildings or reconstructions of existing ones can be seen. The facts and laws of the universe that people live in directly affect their understanding, so developers generally tend to implement these into their virtual environments. However, the factors which shape and govern the real world are not valid in virtual environments. Thus, there are diverse possibilities in the metaverse. This chapter presents the metaverse and its platforms with definitions, usage, interfaces, and problems. It explores the facts of the universe and discusses gaps and lack of designing spaces and buildings in virtual environments by thinking about the possibilities in the metaverse.
