#### **Abstract**

With new technologies related to the development of computers, graphics, and hardware, the virtual world has become a reality. As COVID-19 spreads around the world, the demand for virtual reality increases, and the industry represented by the Metaverse is developing. In the Metaverse, a virtual world that transcends reality, artificial intelligence and blockchain technology are being combined. This chapter explains how artificial intelligence and blockchain can affect the Metaverse.

**Keywords:** AI, Blockchain, Virtual Reality, Metaverse, NFT

### **1. Introduction**

The term "Metaverse" is a combination of 'meta' meaning 'virtual, transcendence' and 'verse' a backformation from 'universe'. The Acceleration Studies Foundation (ASF), a non-profit technology research organization, classified the Metaverse into the following four categories: a virtual world that experiences a flawless virtual story, a mirror world that reflects the current real world, an augmented reality that shows a mixture of augmented information in the real world and life logging, which captures and stores everyday information about people and things [1]. With the development of technology, the number of people who use the Metaverse increases, and as activities at the same level as reality are performed, various and a lot of data are being generated. Data generated in the metaverse has value in itself. In the Metaverse, the amount of data increases, the value increases, and the importance of reliability and security is increasing. Blockchain technology is required to guarantee the reliability of data in the Metaverse, and artificial intelligence is used to secure the diversity and rich content of the Metaverse. The contents will be developed in the following order.

In this chapter, under the theme of the Metaverse, we will look into the issues of human instinct for creation in the virtual world, the phenomenon in which the real and the virtual are combined in the virtual world, and the reliability of data in this virtual world. Blockchain and NFT technologies are described as trust technologies. And the Metaverse platform built on the basis of this technology will be described. Basically, we will understand the interface between blockchain and artificial intelligence, and look at how a better world is created by combining blockchain and artificial intelligence in Metaverse.
