UniWorlds is a 3D sovereign personal content creation platform that fully empowers individuals to construct their own virtual spaces on the Bitcoin network through a 3D creation engine. Leveraging the high performance and security of the Fractal Bitcoin Layer2 network, along with open and decentralized community governance, it motivates more individuals to participate in 3D content creation. This enables a greater number of "super individuals" to establish irreplaceable on-chain identities in virtual spaces, safeguarding against the confusion of human identities in the era of artificial intelligence.
