DBX is a blockchain infrastructure applied to high-frequency valuable data exchange. Based on the original D-DPoS consensus mechanism (based on the proxy mechanism of data property rights certification), DBX applies CES function, dynamic recursive model and other mathematical tools to solve the problems of vote manipulation and oligarchs in DPoS and strengthen decentralized governance capabilities. DBX also provides an efficient and fair data transaction model, adopts a new type of data evaluation smart contract protocol, provides an incentive mechanism to ensure that users' data can benefit from every transaction, and promotes the sharing of data under good protection. The accumulation of extensive data and efficient transaction mechanisms promote the explosive growth of Al/IoT and other applications in the DBX ecosystem.
