Use cases

<–Assumptions Go to ToC External Services–>

This Chapter analyses potential Metaverse Use Cases, sometimes supplemented by specific examples. The fact that one such example is considered in this chapter does not imply that MPAI in any way endorses the specific business model adopted, neither does it suggest any kind of investment, nor that the example should be preferred compared to others not considered. It simply denotes that the business model is worth to be analysed. MPAI welcomes the submission of names of current Metaverse Instances whose business models have characteristics worth being considered for the purpose of defining Metaverse Functionalities. Such submissions should contain a level of detail comparable to the ones used in existing examples.

A section at the end of this chapter will collect relevant workflows derived from the Use Cases.

Professional training

1 Automotive

1.1 Description

The Metaverse has the potential to revolutionise the way vehicles are designed and tested, as it allows for the creation of a collaborative design environment within a virtual space. The design of a vehicle can then be performed entirely within a Metaverse Environment, and the same design can also be virtually tested at different stages of its lifecycle. In addition, a Blockchain-supported Metaverse offers new opportunities for the creation of communities or “cults” centered around vehicles. These virtual communities could bring together enthusiasts and experts to share knowledge, discuss the latest developments in the automotive industry, and potentially even collaborate on vehicle design and testing projects within the Metaverse Instance. The Metaverse also has the potential to enable the interconnection of vehicles, allowing them to communicate with each other and potentially even make decisions as a collective. This could lead to the development of new transportation systems that are more efficient and responsive to the needs of users. For example, a fleet of interconnected vehicles could coordinate their routes and movements in real-time to optimize for factors such as traffic, weather, and passenger demand. The use of the Metaverse for vehicle interconnection could also facilitate the development of autonomous vehicles, as it allows for the creation of a virtual environment in which these vehicles can be tested and refined.

9.3 Examples

9.3.1 Pokémon Go

Pokémon Go[1] is an AR mobile game, part of the Pokémon franchise, developed and published by Niantic in collaboration with Nintendo and The Pokémon Company, and running on iOS and Android devices. It uses mobile devices with GPS to locate, capture, train, and battle virtual creatures, called Pokémons, which appear as if they were in the User’s Universe Environment.

Users can create and customise their own avatars which are displayed on a map based on the Users’ Universe position. Features on the map include “PokéStops” that can be equipped with items used to attract additional Pokémons and “Pokémon Gyms” that serve as battle locations for matches. PokéStops and Gyms are typically located at interesting locations.

Pokémon Go uses a freemium business model, i.e., it is free-to-play: it is combined with local advertising and supports a marketplace for in-app purchases of additional in-game items.

The game can be combined with a “Pokémon Go Plus” device: a Low Energy wearable Bluetooth device that allows Users to perform certain actions in the game without looking at their smart device, e.g., by vibrating when a User is near a Pokémon.

9.3.2 Roblox

Roblox[2] is a Metaverse where users download a basic game free to play from a collection of millions of different games all developed within the same graphical environment provided by Roblox. Famous games are, e.g., “Adopt Me!”, where users care for virtual pets potentially traded with other players, and “Jailbreak” where users play in a virtual ‘cops and robbers’ style game. Roblox provides the tools to its community to create their own games.

Users can download every game without any additional software (unless it is to create a game). Users can also create games in the platform and charge real money for people to play it and can charge for bonus features such as digital skins. Creators can also earn money through advertising and micro-transactions by using the platform virtual currency Robux which can be bought and converted back into real money.

9.3.3 The Sandbox Game

The Sandbox Game[3] is an on-line game in which players can trade digital lands and create Experiences on top of them to share with other users. The Sandbox platform consist of three key parts:

Voxel Editor allows users to model and create in-game assets.
Marketplace is where assets are sold.
Game Maker enables users to build games without the need for coding skills and contribute to improving the Metaverse Experience with new creations and game scenes.

Three different types of Ethereum and Polygon tokens govern the economic operations in The Sandbox:

LAND: an NFT representing a digital parcel.
SAND: a cryptocurrency facilitating purchase of parcels, virtual goods, and services.
ASSET: an NFT representing in-game asset such as equipment and wearables for avatars and creations that are used to populate the digital parcels.

Users can generate revenue by creating ASSETS and renting or selling them or building games experiences.

9.3.4 Minecraft

Started as a simple computer game, Minecraft[4] has built on mining and crafting virtual worlds with Lego-like blocks. Initially there were two main modes: survival and creative. In the survival mode, players found supplies and foods to craft tools and avoid creatures. In the creative mode, players get supplies to build whatever they want, they can fly, and do not need to virtually eat.

Minecraft is available as:

As Java Edition runs on the PC.
As Minecraft Bedrock Edition runs on Android, iOS, and games consoles.
On VR headsets like Quest and Windows Mixed Reality.

After an upfront cost of the initial purchase, updates and additional features are provided for free. Minecraft provides a Marketplace where users can buy virtual currency (Minecoins) and spend it on user-created content. Licensed content is also available featuring popular franchises such as Sonic the Hedgehog, Jurassic World, and Major League Baseball. Users can explore and play games in pre-existing worlds created by other players and content creators. Content creators are compensated when players download their work on the Minecraft marketplace. Many users also stream their playing on Minecraft on platforms such as Twitch or YouTube.

15 Retail

15.1 Description

Important sections of the retail industry have already made advances in experimental uses of the Metaverse. However, we are not yet at the level of Metaverse Instances but of Environments carved out in current Metaverse Instances. The experiments deal with physical goods and virtual goods having value in a Metaverse Instance, but we are at the level of early steps made by specific segments of the retail industry. To leverage the potential of the Metaverse in retail, adequate satisfaction must be provided to human senses, beyond vision and hearing, because of their essential role in the retail experience. Retail means the ability to appeal to customers’ senses to create the psychological conditions that evoke the emotion leading to the willingness to buy.

15.2 Functionalities

By providing a virtual platform for social networking, the metaverse allows Users to create and maintain relationships with each other in a virtual environment. In addition to facilitating social connections, the metaverse could also provide a space for Users to attend virtual events and gatherings, such as concerts, parties, and meetings. These events could range from small, intimate gatherings to large-scale events with thousands of attendees. The metaverse could also present new opportunities for brands and businesses to reach and engage with Users through virtual influencers, potentially leading to innovative approaches to marketing and advertising.

16.2 Functionalities

Events
Social networking
Content creation
Influencer marketing

16.3 Example

16.3.1 Somnium Space

Somnium Space[8] is an open-source, social, and persistent VR world. The platform allows users to buy land, homes, and other in-game assets. These assets are all represented as NFTs, and they are tradable on the Ethereum blockchains. Somnium Space is entirely inter-connected, i.e., all users exist within the same Metaverse Instance, rather than within multiple Metaverse Environments.

Two different types of Ethereum tokens govern the economic operations in Somnium Space:

PARCEL: an NFT representing a digital parcel.
CUBE: a cryptocurrency facilitating purchase of parcels, virtual goods and services used in Somnium Space.

Users can build and monetise Experiences with in-game assets, advertising space, stream their gameplay, create a store in their Metaverse Environment, develop online courses and other Experiences and Events (e.g., concerts), and charge fees for these ventures. Somnium Space gives users the ability to earn CUBEs based on their “Karma levels”, i.e., a representation of social standing and the perceptions of other Users.

18.3 Examples

18.3.1 Voxels

Voxels[9], one of the oldest Ethereum-based metaverse platforms, operates a Metaverse Instance offering 3D Experiences with a global network of Users on a platform running on centralised servers. By means of a web browser, Users explore, interact, and build virtual buildings on virtual parcels. Users can also develop Metaverse Environments such as art galleries, stores, and social spaces.

Each digital parcel is represented as an Ethereum NFT. In a similar way, the Objects composing a Scene (such as decoration elements and avatar costumes) can be associated with an NFT and listed in the Voxels Marketplace and in OpenSea. Trading of the NFT is enabled by OpenSea acting as an External Service Provider.

The current (as of 2022/11/21) workflow of on Voxels Objects unfolds as follows:

A User creates an Objects using Voxel’s software.
The Object is minted as an NFT on the Polygon blockchain.
The Object is listed on the Voxels Marketplace and OpenSea.
The creating User can set the price of the Object and the royalty for future resales in OpenSea.
OpenSea charges another 2.5% on the sale.
When the buying User resells the Object, they will pay the royalty to the creating User and 2.5% to OpenSea.

18.3.2 Decentraland

Decentraland[10] operates a Metaverse Instance offering 3D Experiences with a global network of Users on a platform running on decentralised servers. Users can explore, interact, and play games using interactive apps, make payments, and communicate peer-to-peer through a web browser without specific software requirements.

Decentraland is composed by a set of 126 smart contracts: 101 deployed on Ethereum and 25 deployed on Polygon. The main types of tokens that govern the economic operations are:

LAND: an NFT representing a digital parcel.
MANA: a cryptocurrency facilitating purchase of parcels, virtual goods and services in Decentraland.

An association of two or more directly adjacent parcels of LAND is called Estate. These parcels must be directly adjacent and cannot be separated by a road, a plaza, or any other parcel. Estates are especially useful when building larger scenes that span more than one parcel. Estates are also regulated by a smart contract. Each avatar can be assigned a unique name, managed with a smart contract called NAMES: each name is linked with an NFT.

The platform is governed by the Decentraland DAO that allows MANA, LAND and NAMES owners to vote on how the world behaves: for example, what kinds of wearable items are allowed (or disallowed), moderation of content, LAND policy and auctions, pay for expenses such as software developments, which content servers can join the network, organising events. Community voting power is computed in function of the MANA and LAND allocation of each user.

Aside from the DAO, there is a selected group of users tasked with preventing and handling security issues on LAND and Estate smart contracts. This group of people, called the Security Advisory Board (SAB), comprise several expert entities or individuals initially chosen by the Decentraland team. This team acts as guarantors of contract security, and it oversees providing rapid response to any bug report.

The DAO owns several of the most important smart contracts of the entire Decentraland platform[11], e.g.:

Points of Interest: containing the list of notable locations in Decentraland that are advertised to users as good places to begin exploring the virtual world.
Wearables collections: wearables can be grouped into collections before minting. The relevant contracts are owned and controlled by the DAO.
Marketplace contracts: The Decentraland Marketplace dApp makes use of several smart contracts to manage the process of selling and bidding on LAND, Estates, and other NFTs. These contracts are also where the marketplace fees are defined and can only be changed with the DAOs approval.

Note that the Smart Contracts containing lists of features, such as enabled names etc., can only be modified after a community vote is passed.

18.3.3 Over the Reality

Over the Reality (OVER)[12] is an AR platform that merges Metaverse and Universe Environments where Users can augment and enhance their Experiences, through the lens of their smartphones or smart glasses.

Two different types of Ethereum and Polygon tokens govern the economic operations in Over:

OVRLand: an NFT token that allows decentralized possession of digital assets such as OVRLands (representing a digital parcel that make up the digital layer of subdivision of the Earth into hexagons) and Over Experiences.
OVR: a cryptocurrency utility token used in Over.

OVRLand owners can decide what kind of experience a User can experience once they enter into the Universe Environment associated with their parcel. Av OVRLand owner acquires third party content posted on their parcel and projected into the associated Universe Environment. AR Experiences can range from static 3D content and interactive highly complex and hyper real scenes that make virtual content merge with the real world. The current Devices are based on iOS and Android and Smart glasses such as Hololens[13], Magic Leap[14] and stereoscopic AR headset such as HoloKit[15].
