Accounts

We are a basically FOSS project and we don't charge for anything if you don't charge others for anything. So why do we need accounts? Yes, they're mainly for multiplayer.

Decentralized Authorities

We don't want to limit the authority to only ourselves. That's a problem when Mojang's authentication servers are fragile and everyone can't play multiplayer when they're down.

But how are we going to distinguish players from different servers? The answer is simple: we use the server's identity combined with the player's identity, which is inspired by Mastodon's "appending server name behind username" approach, and we actually don't care about legitimacy of the authentication

In-Game Behavior

In the game we only care about the UUID of the account which is generated by the server and will never collide with other players or other entities.
