Player ownership of game assets is one core area. In traditional video games, in-game items and player characters are owned by game developers. They, and the games, are often run on servers. Storing the items and characters on the blockchain allows for a decentralized, immutable record of ownership that can be separate from the gaming company and its servers.
This, in turn, can help make in-game virtual assets more valuable, liquid, and worth collecting, as players in essence own the virtual items. Trading in-game virtual assets on the blockchain through smart contracts allows for peer-to-peer transactions that can be accessed by anyone on the blockchain, negating the need for centralized control. At the same time, it removes some of the issues connected to fraud.
