The use of blockchain in gaming allows players to have permanent ownership of their assets in the game and to freely buy and sell them. Unlike in the game, the publisher will not own and manage the entire game. Gamers can exchange assets between games by integrating in-game item data with tokens. Blockchain and smart contracts have the potential to lower transaction costs and speed up transaction processing in the Game. They can offer a range of payment options to gamers, making it easier for them to swap money.
