DataBase X (shortened as DBX), would be a whole new infrastructure for the new world on blockchain. The vision of DBX is to enable any proper demand of database being easily satisfied: all data around the globe are accessible, retrievable, analyzable and tradable.DBXChain will create a new world for value-based data assets at the dawn of blockchain era. Each one would regain his/her natural rights of his/her data, making decisions and gaining benefits upon their data with a totally new fair consensus mechanism—D-DPoS.As a basic public chain, DBX also provide a new structure of smart contract running on DBXChain. The typical contract consists of wallet address, data transport location, requests for several DApps for data verification or quality testing, data sampling methods, number of Trinity nodes for a third party evaluation, fees and other arrangements like price, deposit, transaction channel, etc. Obeying the principle of "code is law", smart contract in DBXChain would ensure the fairness between both parties and maximize the trading efficiency.Members of DBX Community could initiate a Data Contest to collect data through DBX network.One of the key parts on DBX ecosystem is "Data Game" which is a well developed DApp to help its user participating the data contests, users could choose to provide multiple kinds of data and get reward or paid. On DBXChain, developers could create various DApps to explore the value of data for this immense data asset world. Besides basic smart contracts and BaaS, DBXChain would also provide plenty kinds of structured/unstructured data sets, automatic trading network for data, a great number of data analysis DApps, and a high efficient blockchain system with 1,000,000 TPS, which together lay a solid ground for commercial product.
