Current metaverse platforms are very limited in terms of the number of concurrent users that can interact in a space.
Depending on the platform, there are only 40-100 avatars!
One technological approach to break through this limitation should be so-called spatial partitioning.
Simply put, the three-dimensional world is broken down into 2D tiles, which are then played out per user via synchronized cloud servers and then reassembled into a 3D world. Theoretically, such a platform can be scaled indefinitely.
In the meantime, however, it has become apparent that the problem lies precisely in the synchronization of the servers(see the current article in MetaGravity)
But exactly this scalability is necessary to be able to really talk about a metaverse in the future and not only about 100*X cloned avatar islands. This does not only apply to games in the metaverse. Also for events like fairs and events an unlimited number of concurrent users is absolutely necessary.
It remains to be seen what technological developments there will be here in the near future, and who the drivers will be.
