Some of the most popular games in the world are online role-playing games, such as World of Warcraft. In many of these games, players can accumulate and trade equipment. A common issue for game creators has been the in-game economy: How do you enforce the scarcity of rare items online? Many games have been subject to duping bugs, where a player can duplicate a rare item over and over again and then sell it, thereby making a substantial profit. Blockchain technology solves the issue of digital scarcity.

There are already a few video games experimenting with blockchain technology. However, while there are a few Ethereum-based tokens for gaming, there are no blockchains just for video games yet. We expect this to change, as some of the most lucrative games around make their money through the sale of in-game items.
