GameHub is a gaming ecosystem designed to shake the monopoly of the traditional gaming industry with blockchain technology that will optimize mobile gaming data transfer and digital marketing by eliminating the middlemen. GameHub created the PlayCoin cryptocurrency, which serves as a unit of calculation in the GameHub ecosystem, helping game developers and powerful players generate revenue and create more competitive conditions. Currently, several major players, such as the Google Play, App Store and Tencent, have a monopoly on the distribution of games and charge commissions of 30-80% from game developers. Using gift cards increases commissions even more. GameHub will provide an alternative platform for downloading games with lower commissions, as well as tools for promoting games using smart contracts.
