The non-blockchain Metaverse encompasses all forms of virtual worlds. From centralized ones like Grand Theft Auto (GTA) or the legendary Sims to the increasingly popular metaverses. For example, Minecraft or Roblox's shopping mode. However, thanks to blockchain technology, the economies, and markets built within have put ordinary people and investors in the spotlight. In this regard, the role of NFTs in representing the value of assets traded on them has been critical.

Blockchain allows for the transformation of the concept of Metaverses, multiplying their possibilities by connecting the physical and virtual worlds. Blockchain Metaverses are locations where a parallel economy to the real one, but entirely digital, develops. Users can monetize their skills in these metaverses by purchasing land, pizzas, art, clothes, cars, and so on. As with the internet, all companies will most likely establish headquarters in the Metaverse in the near future.

Different types of metaverses can be categorized based on their purpose, technology, and user experience. Social metaverses, like Meta’s Horizon Worlds, focus on virtual social interactions, allowing users to engage with friends, attend events, or explore shared virtual spaces. Gaming metaverses such as Decentraland and Roblox offer immersive environments where users can create, play games, and even earn virtual assets.

Enterprise metaverses, like Microsoft Mesh, are designed for professional use, enabling virtual meetings, collaboration, and training in 3D environments. These often prioritize productivity and work-related functions. Additionally, decentralized metaverses leverage blockchain technology to allow users to own and trade digital assets (e.g., NFTs), offering more control and opportunities for monetization. Each type caters to different user needs and levels of engagement.
