An Architecture for Game to Game Data Transfer Using Blockchain

Blockchain has been used in several industries, especially in the financial area. In the game industry, blockchain has not been utilized much even with a large number of users who deserve to own their game data. There were attempts to allow players to own their in-game objects or data. But they were mostly crowdfunding platforms which were not yet in operation. In addition, users were required to use their ecosystem. In this paper, we propose a generic game architecture, using blockchain, that allows players to own their “spent time” in a game. The value of this spent time can be passed on to new games as ERC20 token on the Ethereum network and redeemed in such games. Our architecture can be used with any public blockchain. It can benefit many roles such as player, blockchain node, and game developer. Our experiment shows that the proposed architecture can be accepted by players, but other factors such as the type of gameplay and how the spent time is exchanged in a game can greatly affect the player acceptance.
