The 1990s brought the proliferation of the internet throughout the world. Researchers developed various computer-mediated virtual environments including social networks, video conferencing, virtual 3D worlds, augmented reality applications, and Non-Fungible Token games. The term ‘metaverse’ has been coined to encompass the digital transformation in every aspect of our physical lives. At the core of the metaverse is the vision of an immersive internet as a gigantic, unified, persistent, and shared realm. While metaverse may seem futuristic, it is catalyzed by emerging technologies, such as extended reality, human-computer interaction, artificial intelligence, blockchain, computer vision, IoT and robotics, edge and cloud computing, and future mobile networks. In terms of applications, the metaverse ecosystem allows human users to live and play within a self-sustaining, persistent, and shared realm. The metaverse is a virtual and visual world that combines physical and digital experiences. At present, the development and implementation of the metaverse is in the nascent stage and lacks a framework for visual construction and scrutiny. Therefore, this book offers a 360-degree exploration of the metaverse, with a focus on avatars, content creation, virtual economy, social acceptability, security, privacy, trust, and accountability.
This book provides a thorough explanation of how the technology behind metaverse and other virtual reality is changing the world. The primary objective is to present the revolutionary innovation of the 21st Century—the metaverse—and exhibit its wide range of applications in different domains. Although blockchain and VR/AR were the first popularly known applications of the metaverse, several other applications also exist. While some still believe the metaverse is overhyped, in reality, it is transforming almost every industry—healthcare, 3D, 4D, industry, game industry, business management, artificial intelligence, and IoT, just to name a few.
This technological breakthrough not only paved the way for virtual reality, but provides useful solutions for other areas of technology. The unique nature of the technology, which is a single, shared, immersive, persistent, 3D virtual space where humans experience life in ways not possible in the physical world, makes it suitable for all real-world applications. The technology has great potential to transform business, and companies are already in the race for different product offerings.
The book is organized to cover all aspects of the metaverse, including its fundamentals, features, working principles, and application in different sectors.
Chapter 1 presents an in-depth analysis of the technologies used in the metaverse and provides a solid foundation from which to further study this fascinating field. Specifically, the chapter presents the fundamental characteristics of a novel-distributed metaverse architecture in terms of ternary-world interactions. The benefits and drawbacks of the metaverse are explored, along with the current pressing problems faced by metaverse systems and their most cutting-edge solutions. Finally, the chapter proposes new avenues for the study of metaverse system developments.
Chapter 2 investigates the expected utilization of blockchain innovation in the metaverse, explicitly in the spaces of AR, VR, and MR. The specialized parts that utilize blockchain in these virtual conditions are examined, including how it tends to be leveraged to get client data and works with exchanges inside the virtual world.

The Metaverse is a concept that is currently being developed for the future generation of the Internet. It aims to provide an autonomous, completely immersive, and spatiotemporal virtual community where people can work, play, and interact. Recent advancements in cutting-edge technology such as augmented reality, Artificial Intelligence, and blockchain are making the once-fantastical metaverse seem more like a plausible reality. This paper presents an in-depth analysis of the technologies utilized in the Metaverse, providing a solid foundation from which to further study this fascinating field. To be more specific, we look into the fundamental characteristics of a novel distributed metaverse architecture in terms of ternary-world interactions. The benefits and drawbacks of the metaverse are then explored, along with the current pressing problems that metaverse systems face and the most cutting-edge solutions to those problems. Finally, we propose new avenues for metaverse system development study.
Keywords: Augmented reality, artificial intelligence, blockchain, metaverse
The term “metaverse,” which was first used by author Neal Stephenson in his science fiction novel Snow Crash, was first published in 1992 [1]. “Meta” comes from the Greek for “beyond,” and “verse” means “universal.” The novel depicted the metaverse as a virtual counterpart to the real world or a dystopian version of the internet. Shared term “metaverse” is also used to describe virtual worlds where users can enter as digital avatars and conduct business or social interactions with other users. The metaverse is intended to be an alternative to the World Wide Web that is more immersive. There have been several expansions of the Metaverse. In the late 1970s, text-based interactive games like MUD (Multi-User Dungeon) were released, depicting a multiplayer virtual environment with role-playing, interactive narrative, and online conversation. At the time, the term “Metaverse” didn’t exist. These games might be considered the forerunners of the Metaverse. Commercial virtual worlds like Second Life were created during the post-millennial era, which marked the start of the second phase. After that, a fully virtualized 3D environment was approved, such as OpenSimulator, which is normally compatible with Second Life [2].
The metaverse is an ever-present, cooperative online environment where users can participate in interactive narratives. It combines several technologies, including Mixed Reality (MR), Virtual Reality (VR), Extended Reality (XR), Augmented Reality (AR), the Internet of Things (IoT), Artificial Intelligence (AI), Non-Fungible Tokens (NFTs), and Information and Communications Technology (ICT) infrastructure. The Metaverse is currently being developed by IT firms as the successor to the mobile Internet. The Metaverse will eventually surpass the Internet in terms of transforming new service ecosystems in all spheres of human endeavor, including healthcare, education, entertainment, e-commerce, and smart industries. The excitement surrounding the Metaverse is primarily driven by two factors. First off, the COVID pandemic has caused a paradigm shift in how people currently engage in work, entertainment, and socializing. As more individuals get used to doing these physical activities in virtual reality, the Metaverse will become necessary. Second, the Metaverse is becoming a more real prospect thanks to newly developed technical enablers [3, 32].
The basic characteristics of the Metaverse include:
Synchronous and live: The Metaverse will be a living experience for everyone, just like “real life,” with pre-scheduled and self-contained events.
Persistent: It simply keeps going without ever pausing, restarting, or stopping.
Available individually and concurrently: Everyone can join the Metaverse and participate in an event, venue, or activity with their agency. In a well-functioning economy, people and corporations should be able to create, own, invest in, sell, and be reimbursed for many acts that create value. These actions include creating, selling, and being remunerated for goods and services.
An experience: All aspects of the user’s environment, including online and offline spaces, closed and open systems, and public and private networks, should be considered [33, 71].
A wide range of contributors: There should be a wide variety of content and activities, with many different people (some of whom work independently, others for for-profit enterprises) involved [4].
Offer unprecedented interoperability: There needs to be seamless sharing of information, digital assets, content, and other elements throughout the various platforms; for instance, a car built for Rocket League (or even Porsche’s website) may be adapted for use in Roblox. The way things work in the digital world of today is comparable to the way a shopping mall operates, with each establishment having its own money, ID cards, proprietary units of measurement for items such as shoes or calories, and separate dress requirements, among other things [5, 72].
Infrastructure: Answers to the question “What are the key characteristics of the metaverse?” would emphasize infrastructure. In the context of the metaverse, infrastructure refers primarily to the technological infrastructure supporting the metaverse. In addition to utilizing high-tech components such as GPUs, the infrastructure consists of communication technologies such as Wi-Fi, cloud computing, and 5G. The continued expansion of the metaverse is one of its defining features. Therefore, the metaverse architecture must offer ultra-low latency, tremendously fast speeds, and expanded capacity [34, 35]. A robust infrastructure serves as the basis for smooth, value-based experiences for all metaverse users. Recent endeavors make the emphasis on infrastructure as a crucial entrance among metaverse elements abundantly clear. The ICT Ministry of South Korea laid the groundwork for an alliance between seventeen distinct enterprises and eight distinct industry organizations. To promote the growth of the metaverse ecosystem, the industry alliance offers crucial opportunities for enhancing the metaverse’s infrastructure [6, 73].
Human Interface Technologies: When discussing infrastructure as one of the primary metaverse characteristics, it is natural to resort to human interface technologies. For joining the metaverse, users can utilize technology such as VR headsets, haptics, AR glasses, and many more. The human interface technologies aid in transferring users to the metaverse’s endless immersive places. However, advances are being made to human interface technology for the metaverse. Smartphones, laptops, tablets, and personal computers can also function as metaverse access points when equipped with the necessary features [7, 74].
Digital Avatars: Avatars are a key feature among the significant characteristics of the metaverse. Digital avatars are one of the core components of the metaverse’s design. Users can develop digital avatars for unconventionally expressing their thoughts and feelings in the metaverse. You can use the metaverse features to create personalized digital avatars, allowing you to create a digital version of your favorite superhero. Intriguingly, the ability to create and modify digital avatars in the metaverse also provides new opportunities for gamification. Consequently, digital avatars build the foundation for an engaging and immersive experience within the metaverse. Imagine 4.66 billion internet users creating digital avatars, exploring the metaverse, exchanging knowledge, and engaging with other avatars. Isn’t this a truly revolutionary experience?
Decentralization: Decentralization would be the second most prominent response to the question, “What are the key characteristics of the metaverse?” The metaverse is envisioned as an open, shared reality in which users can travel fluidly between platforms. Users of the Metaverse might generate their own virtual experiences and assets with monetary worth and sell them without the need for centralized authorities [37]. This is where decentralization, a prominent aspect of the metaverse, would be found. Some of the most important technologies promoting the democratization of the metaverse are blockchain, edge computing, and AI [8]. Users can obtain complete control and ownership over their assets and experiences in the metaverse through decentralization. Consequently, the decentralized character of the metaverse plays a significant role in deciding the freedom of users. Therefore, the decentralization aspect differentiates the metaverse from the current Internet [36].
Figure 1.1 Core attributes of a metaverse.
Experiences: The metaverse is essentially an open, featureless virtual environment devoid of experiences. The most significant highlight of the metaverse’s essential aspects is that the experiences facilitate the transfer of multiple physical events under a virtual roof. Most importantly, the metaverse promises to link together all physical and digital experiences. For instance, students and professionals could remotely collaborate in shared learning and working areas. In the metaverse, it is possible to create more interactive user experiences by combining disparate events under a single context. Teachers can take kids on a field trip without actually traveling to the location [9].
Security: There is no reason to forsake metaverse security precautions, though. One of the most significant difficulties that organizations all around the world face today is ensuring their networks are secure. Therefore, security problems also offer negative issues for the metaverse. To address such problems, the metaverse provides ecosystem-wide ethical and privacy rules as security measures. Although the metaverse is still under development, the importance of security as one of its defining characteristics cannot be emphasized. The metaverse requires improved user protection measures and user IDs. It is reasonable to emphasize the relevance of ethical behavior given the number of companies working on the creation of the metaverse [10].
Persistence: You would also remark on another notable element of the metaverse in the form of persistence. A popular misconception about the metaverse is that it is a virtual reality universe. You must don your VR headsets to access the metaverse’s virtual universe. However, what happens when the headset is removed? Does the universe within the metaverse end there? No. The metaverse continues to function even when you are unplugged. Imagine playing an online multiplayer game in which the other players continue to play even when you are not present. VR experiences are exclusive to the company or brand that offers the experience. In contrast, the metaverse is an infinite, open realm that never sleeps, exactly like the physical universe. Therefore, persistence stands out as one of the most significant features of the metaverse, as it is always accessible [11].
Production Economy: In terms of value, the creator economy has precedence over all other aspects of the metaverse. How will the metaverse provide users with value? Games, in general, are certainly entertaining to try out for a while. However, this does not justify the purchase of pricey devices to engage in the metaverse.
What About Work and Education?
You could still access Zoom meetings on your mobile device and interact in virtual workplaces using your laptops and desktop computers. The creator economy provides metaverse users with access to design tools for the creation of digital products and experiences that they may own and trade on markets. Therefore, the creator economy is one of the most noticeable metaverse characteristics demonstrating its future significance [12, 38, 39]. Figure 1.1 shows the core attributes of a metaverse.
Jon Radoff is an entrepreneur, author, and game designer who has written extensively about “Building the Metaverse.” The seven layers of his conceptual framework explain the metaverse market’s value chain. Infrastructure is the foundation layer, so without a suitable framework, subsequent advancements are not possible [12]. As a result, technical operations are situated smack dab in the middle of the metaverse’s various layers. Figure 1.2 explain the seven layer of the Metaverse. The stages involved in the framework are gaining experience, making discoveries, establishing a creator economy, conducting spatial computing, decentralizing power, and interacting with humans.
Figure 1.2 Seven layers of metaverse.
Layer 1: Experience
The majority of firms and individuals are now focusing on this layer. In digitally-driven environments, users interact with content such as gaming, retail, NFTs, e-sports, and theatre. The metaverse is not only a three-dimensional depiction of reality. It will be the pinnacle of the virtualization of physical space, goods, and distance. When physical space dematerializes, the limitations that are imposed physically will be lifted. As a result, the metaverse will provide everyone with an abundance of experiences they cannot currently enjoy. Multiple Interactive Live Events (MILEs) hosted on platforms such as Decentraland and Roblox exemplify how the metaverse will make these events available to anyone. Live entertainment-inspired events, such as music concerts and immersive theatre, which have already been featured in Fortnite, Roblox, and Rec Room will become more prevalent in video games. Social entertainment will supplement e-sports and internet groups. According to Jon Radoff, customers are increasingly becoming content providers [12]. Not only in the obsolete sense of “user-generated content,” but also as events and social interactions.”
Layer 2: Exploration
The discovery layer is concerned with the pulls and pushes that expose new experiences to humans. “Pull” refers to an incoming system in which users actively seek information and experiences, whereas “push” is more outgoing and consists of procedures that alert users of upcoming metaverse encounters [13, 40]. In truth, the discovery layer is the most profitable for businesses. Among the inbound and outbound discovery methods are:
Inbound: Marketing strategies include user-generated content, search engines, real-time presence, app stores, and earned media.
Outbound: social media, paid media, and earned media.
Outbound: Display advertising, email, and social media, as well as notifications
Community: Generated content is a significantly more cost-effective method of discovering new things than traditional marketing. As content becomes easier to exchange, barter, and share across an increasing number of metaverse contexts, it becomes a marketing asset. Content markets will replace application marketplaces as a discovery mechanism.
Real-time presence is a crucial facilitator of incoming discovery. The discovery of metaverse experiences will not rely solely on content, but also on knowledge of what other metaverse enthusiasts are doing right now. In the end, interpersonal interactions through shared experiences are what the metaverse is all about. When a person joins Steam, Battle.net, Spotify, Xbox, or PlayStation, they may be able to view the games their friends are playing. These gaming systems have skillfully utilized real-time presence to boost in-game engagement [41].
The metaverse can digitize social institutions and develop a decentralized identity ecosystem, moving authority from a few monolithic entities to social groupings to facilitate the frictionless flow of knowledge and experiences. Display advertising, alerts, emails, and social media are the most effective outbound channels for discovery. Metaverse experiences can also be discovered as a result of metaverse developers distributing relevant content to the public through outbound channels.
Layer 3: Creator Economy
“Creators receive access to tools, templates, and content marketplaces that reorient development from a bottom-up, code-centric approach to a top-down, creatively-centered one,” says Jon Radoff. The creator economy includes design tools, software, and workflow platforms used to create metaverse experiences [14, 42, 43]. Content creators will shape this atmosphere. They have had great success on social media and will continue to be a prominent metaverse development engine. They will create metaverse venues for audiences to interact, socialize, and engage. Creators can offer commercial products, NFTs, and IRL products and showcase and sell NFT collections to make money in the metaverse [15]. Throughout history, creator economies have developed in predictable ways, whether in the metaverse or games, the establishment of websites, or even e-commerce
Pioneer Era:
Because the first people to build experiences for a particular technology lacked the appropriate tools, they were forced to create each experience from scratch. The earliest websites were written in HTML, while users created shopping carts for online stores and game developers wrote code directly to the graphic hardware [
16
].
Engineering Era:
The initial market tools are meant to help overworked engineers save time by supplying SDKs and middleware. In games, the introduction of graphics frameworks such as OpenGL and DirectX enables developers to create 3D visuals without using low-level programming. Ruby on Rails has facilitated the creation of data-driven websites by developers. In the current period, the number of creative individuals is expanding at an alarming rate. Creators are provided with tools, templates, and content marketplaces that transform development from a code-centric, bottom-up process to an aesthetically-driven, top-down one. Using game engines such as Unity and Unreal, it is possible to create 3D visuals without having to rely on the fundamental rendering of their studios’ visual interfaces [
15
].
Creator Era:
The experiences that content creators have within the metaverse are now primarily focused on centralized platforms such as Roblox, Rec Room, and Manticore. An unprecedented number of people have been given the ability to create user experiences as a result of these platforms’ complete sets of integrated tools and discovery, social network, and monetization functions [
44
].
Layer 4: Spatial Computing
Combining the real and the virtual, spatial computing blurs the boundaries between the actual and ideal worlds. Spatial computing has evolved into a large category of technology that enables the exploration and modification of 3D locations and the addition of extra data and experiences to the real environment. The key characteristics of this layer include 3D engines such as Unity and Unreal. In addition to mapping and analyzing the inner and outside worlds, geospatial mapping with Cesium, Descartes Labs, and Niantic Planet-Scale AR also aids in mapping the inner world. Integration of device data (Internet of Things) and human biometrics is already prevalent in the health and fitness industries. Incorporating speech and gesture recognition into spatial computing software is the final step [17, 45].
Level 5: Decentralization
In a perfect scenario, the metaverse would be decentralized, open, and diffuse - administered by a single entity and belonging to no one and everyone simultaneously. Choices are maximized when systems are interoperable and developed in a competitive market, which increases experimentation and development. Moreover, creators have ownership over their data and products. Decentralization encompasses the blockchain, smart contracts, open-source platforms, and, eventually, the possibility of a digital identity that is fully autonomous. Developers may use online capabilities more easily using distributed computing and microservices. The most famous decentralized metaverse is Decentraland. It’s a blockchain-based virtual world administered by a Decentralized Autonomous Organization whose laws may be changed by voting. In the metaverse’s decentralized regions, people and businesses are buying land [18, 46–48].
Layer 6: Human Interface
Human interaction is a crucial aspect of the hardware layer of the metaverse. Moreover, biosensors and neurological links between brains and computers are currently being evaluated. However, neural networks and haptic technologies are also included. This layer also contains haptics, which enable the transmission of information via touch even when no physical items are present. Using haptics, it is possible to control electronic devices in mid-air without touching buttons or a display [18, 46–48].
Layer 7: Infrastructure
The seventh layer ‘infrastructure’ consists of the technology that makes the preceding items possible. 5G and 6G networks, Wi-Fi, cloud architecture, AI, AR/VR/MR, blockchain, and graphics processing units enable the metaverse (GPUs). 5G networks will exponentially increase capacity while simultaneously reducing competition and latency.
The metaverse world is made up of seven main technologies.
Technology 1: VR, AR, and XR
Virtual Reality (VR): VR is by far the most well-known and used of Metaverse Technologies. This is an experience that makes you feel like you’re in the real world. This technology is used in the real world for things like online games, social media, education, and job training, among other things. The Metaverse has the potential to upend several businesses by making available VR-based technologies that can whisk people away from their living rooms and into an alternative virtual world. Facebook Horizons lets users meet new people from around the world, participate in exciting activities, and construct their virtual worlds. It’s a global gathering area where individuals may collaborate in real-time. The finest VR headsets are Oculus Quest, HTC Vive, Cosmos, Sony, Playstation VR, and Valve Index [19].
Augmented Reality (AR): The real world is made clearer to us through the use of a technology known as AR, which superimposes information generated by a computer on top of what we see. These days, augmented reality apps for smartphones rely heavily on the user holding the device in front of them. The software can show contextual information or provide realworld gaming and social activities by processing the camera image in realtime. Smartphone AR has progressed greatly in the previous decade, but its applications are still limited. Wearable smart glasses are becoming an increasingly important tool for giving an AR experience that is more comprehensive. These devices need to have a form factor that is light enough to be worn for long periods, as well as a processor that uses a very minimal amount of power. Additionally, they need to have several sensors, including ones for depth perception and tracking [19, 49].
Extended Reality (XR): The term “XR” refers to the metaverse in which AR, VR, and MR exist. Popular Extended Reality Metaverse games on TVs include Fortnite, Roblox, and ZEPETO. In addition to its use in video games, extended reality has many other applications. Evidence-based examples of educational materials that take advantage of augmented and virtual reality simulations and tools with Artificial Intelligence, location services, and language translation capabilities have been developed. For example, the United States Army has been using a VR dome for years to teach soldiers. 120,000 HoloLens augmented reality devices were purchased by the military for use in both training and battle [20].
Technology 2: AI and ML
Artificial Intelligence (AI): AI may help create Metaverse elements including characters, landscapes, buildings, character routines, and more. Unreal Engine may soon have sophisticated AI. AI could automate software development, allowing users to generate more complex Metaverse items with less effort. On the blockchain, smart contracts may also be created, audited, and protected with the assistance of AI. Without artificial intelligence, it will be difficult to develop a Metaverse experience that is appealing, lifelike, and scalable. To lessen the risks of artificial intelligence while maintaining its potential, businesses like Meta collaborate with think tanks and ethics organizations.
Metaverse Uses AI in Various Forms
Avatars: The concept of an avatar is one of the most intriguing and hotly debated topics in the Metaverse. Artificial intelligence can analyze 2D user images or 3D scans to build Avatars that are very accurate and lifelike. Artificial intelligence is already being used by some companies, such as Ready Player One, to help in the creation of Avatars for the Metaverse.
Digital Human: In the Metaverse, digital humans are three-dimensional chatbots that respond to users in virtual reality. It’s made of AI technology and is fundamental to the Metaverse’s architecture. NPCs are non-playing characters in virtual reality and games. NPCs are scripted, unlike user-controlled characters [21].
Language Processing: Individuals will have unrestricted access to the Metaverse once artificial intelligence is implemented and put to use for this purpose. An artificial intelligence system can understand human languages such as English and translate them into a format that a machine can read. Following the completion of an analysis, the output, also known as the answer, is translated back into English and delivered to the user.
Technology 3: Blockchain
The Metaverse, which is built on the blockchain, allows users to visit any virtual area without going through any kind of centralized server. The six metaverse categories of digital ownership, collectibility, value transfer, governance, accessibility, and interoperability are where blockchain shines. The metaverse is a good fit for blockchain technology since it is open and affordable. Blockchain technology in the Metaverse may be applied to in-game real estate, virtual currency, non-fungible tokens (NFTs), self-identity authentication, and virtual currency [50–53]. A digital economy can flourish thanks to the existence of virtual currencies in the metaverse. Assets in blockchain games are often validated cryptocurrencies, like NFTs or crypto tokens, and are held on the chain in a decentralized way due to the games’ decentralized and Web3-oriented nature. Each participant independently controls and owns their copy of the game. In the gaming Metaverse, MetaBlaze stands out as a GameFi x Defi utility coin with broad applicability across the entire web3 ecosystem. Players may build and immerse themselves in a high-level, 3D, play-to-earn RPG with unique content, stunning visuals, and incredibly thrilling gameplay, all within the first Blockchain-gaming Metaverse to offer players permanent rewards [22, 54–56].
Technology 4: IoT
Metaverse IoT apps collect and share data. IoT can connect a huge number of real-world devices to 3D. Metaverse simulations are real-time. AI and machine learning may help IoT manage data and improve the Metaverse. Metaverse will analyze and interact with the real world using IoT. Metaverse will customize IoT user experiences in 3D. Metaverse and the Internet of Things will enable data-driven decisions with minimal mental effort and training.
Technology 5: Brain-Computer Interfaces (BCI)
Technological advancements in the field of brain-machine interfaces In the Metaverse, technology can take the reins from the human brain, allowing for the control of avatars, a wide variety of digital products, and digital transactions. Markets for video games and employee efficiency are seen as early adopters of this technology. In the early stages of the Metaverse, this technology will not be crucial. However, early adopters may start employing brain-computer interfaces by the mid-2030s to link up with the neocortex. The human brain’s neocortex is where advanced thought is processed. A brain-computer interface device, like the one used in the virtual reality game Awakening by Neurable, uses an electrode-laden helmet connected to an HTC Vive head-mounted display to track brain activity. The software examines game data to identify the proper course of action. The most well-known businesses are Neurolink and Nextmind [23, 57].
Technology 6: Three-Dimensional Reconstruction
Users will be able to virtually tour new constructions from anywhere in the world using 3D models reconstructed in the metaverse. The major problems of the metaverse are solved by this method, which employs 3D reconstruction to build realistic and natural-looking landscapes in a digital environment that mimics the real world as nearly as possible.
By using high-resolution 3D cameras, internet users can digitize their environments in stunning realism. To create a virtual replica for metaverse viewing, the 3D spatial data and 4K HD photos are sent to computers where they are processed. Some people also use the term “digital twin” to refer to these simulations of physical objects [24].
Technology 7 – 5G
Metaverse is the future of real-time communication. The Metaverse requires high bandwidth, latency, and internet connections to join a vast virtual environment with realistic graphics and polygon counts. With 5G’s extremely high millimeter-wave frequencies, users can have immersive, real-time dialogues with artificially intelligent characters in virtual reality (VR) and augmented reality (AR). Roaming features improved render LOD, user-friendly API integration and Developer Platforms would all contribute to a wider audience.
Realistic immersive experience: It gives sensory, object, and environment realism and has fueled Metaverse interest.
A complete world structure: The Metaverse will be an exact duplicate of the physical universe, mimicking all ten of its constituents.
UGC (User-Generated Content): Residents of the Metaverse generate material and apps in their virtual worlds using UGC, a new creative arena.
Huge economic value: Metaverse platform architects will use technology to create scarcity and tamper-proof data. The Metaverse’s lower scarcity allows it to outperform the actual world economically.
Reforms: As a parallel universe, the Metaverse must reduce “central privilege” in the real world.
Significant uncertainty: Governance structure is the central question in the Metaverse, more specifically, who will lead its future governance system. All designers of the Metaverse will have to determine who has the last word in the virtual world and who owns its economic benefits [3].
If we accept that the Metaverse is an inevitable extension of our highly linked world and the subsequent iteration of the World Wide Web, then the crucial question will be how to access the Metaverse. Unknowingly, you may be a part of the in-development version of the Metaverse. For instance, if you are a Web3 user, have a crypto wallet, or have purchased an NFT, you are already a part of the Metaverse [7
