ugChain – Blockchain for Gaming

ugChain is the first ecosystem consisting of a series of decentralized applications in China, and its core is a decentralized account system (DAS) based on blockchain technology. The system has built-in exclusive token UG Token (UGT), which simultaneously has the equity attribute and monetary attribute.
The DAS is a decentralized account system featuring user autonomy built on the Ethereum, providing hassle-free user experience in information authorization across service providers – by only requiring user to provide the signature with his/her private key, rather than traditional experience to register and log in with password under each centralized service provider. This architecture enables user to save his/her account by himself/herself without depending on storage of the centralized service provider.
