Assets portability enables players to transfer their on-chain assets into Minecraft worlds; and also the other way around. This incurs two problems: how to tokenize in-game assets and how to import on-chain 3rd party assets into Minecraft worlds.
In-game elements that could be tokenized includes but are not limited to
Metacraft protocol will provide a toolchain that helps players to tokenize these in-game elements. The generated tokens will be compatible with ERC20, ERC721, and ERC1155 protocol so that all assets based on this standard can live in the game.
Tokenized assets can be traded in on-chain marketplaces. Although this may not make sense for all types of assets (low-value assets do not worth trading), the free market itself will adjust the liquidity for all assets and eventually grow a high-efficient economic system.
This toolchain will be built in the form of Minecraft mods and plugins with easy-to-use API and proper documentation.
