TLDR from article attached.
"To ensure that Minecraft players have a safe and inclusive experience, blockchain technologies are not permitted to be integrated inside our client and server applications, nor may Minecraft in-game content such as worlds, skins, persona items, or other mods, be utilized by blockchain technology to create a scarce digital asset.

Some companies have recently launched NFT implementations that are associated with Minecraft world files and skin packs. Other examples of how NFTs and blockchain could be utilized with Minecraft include creating Minecraft collectible NFTs, allowing players to earn NFTs through activities performed on a server, or earning Minecraft NFT rewards for activities outside the game.
