Minecraft, a 3D sandbox game, is getting a blockchain version with Polygon overlay. NFT Worlds, a modified version of Minecraft's servers, relies on the sidechain to store all data about play-to-earn mechanics.

According to the game description, world owners can create their own "limitless metaverse games" or experiences for players or exclusive communities within their worlds.

The game has its own ERC20-based token called WRLD for economics. In many NFT Worlds, the token is necessary for players to access the content, perks, competitions and more that world owners have created in their worlds.
