Having a universal identity means that the player can use the same identity when playing in different Minecraft worlds. This is a basic requirement for a multi-worlds game and a metaverse.
Metacraft protocol uses the web3 identifier, i.e. wallet address, as the player's sole identity handle across different worlds in the Metacraft metaverse. (Players will still need to log in the game with their purchased Minecraft account to enforce EULA compliance)
This ensures identity compatibility with all the other crypto products so that crypto-assets can be imported into the gaming world in a seamless way.
To make this integration to the original Minecraft authentication system, Metacraft will provide user-end plugins along with a custom authentication server.
