Konami makes this really great projection system that keeps track of game state and projects onto a big table and they give/lease/sell these devices to game stores. The device comes installed with trusted public keys of a certificate authority managed by Konami and will only work with virtual cards issued by Konami. The ownership of those virtual cards is handled by a mechanism not managed by Konami. This is basically how Yi-Gi-Oh physical cards work. They make official cards and they don’t manage the ownership of those cards. The advantage for Konami is that they don’t need to build much of any infrastructure for a market for trading or selling virtual cards. The advantage for players is they don’t have to rely on Konami for these ownership related features and can buy, sell, lend as they see fit. The MTGO marketplace is really awful but it’s the only choice that MTG players have if they want to buy, sell or trade virtual MTG cards.
