Say you are a game developer and you are creating a game like WoW or EVE online where items can be traded via an in-game market. You can design the whole system from scratch yourself or plug in to the various blockchains and use the dev cycles elsewhere. You could represent each item with a 32byte id and each player’s inventory with a wallet. Bonus: say a new WoW private server spawns up (there are tons of these around). You can offer the option to a player to “migrate” from another server and keep all their items. All they have to do is provide a digital signature from the original server to show that they own the items.
