Fabio Alessandrelli (fales) discusses the new high-level online multiplayer API that will ship with Godot 3.0, with a focus on some limitations and potential exploits (user impersonation). He also presents his own take at improving the current system to make it more robust and user-friendly.

Note that this talk supposes some knowledge of networking principles. Check out Fabio's earlier talk at GodotCon 2017 for a more general introduction to real-time online multiplayer with Godot: https://www.youtube.com/watch?v=1PHNj2Mitg8
