EnGameChain original purposes are to ensure fairness, safety and convenience of games and provide technical support and entertainment channels for it. The decentralization can expend the inherent concept of gambling, and provide open source systems for the participation and application of game developers. EnGameChain aims to create a public chain reforming the online entertainment and gambling industry. First, the decentralized technology of the blockchain can challenge trust system problem of the traditional gambling platform and eliminate credit boundary and rent-seeking space existing in various ends, enabling all transaction behavior to be transparent. The consensus mechanism of the blockchain is used as operating medium to enable the platform, bookkeeping of various ends in the industrial chain, conversion, clearance and settlement and deadline management to be operated efficiently. In order to avoid the increase of users’ uncertainty caused by monetary fluctuation of main chain, the project also designs a unique token system.
