The data token is upgraded, and the old token is renamed dataX. STREAMR tokenizes streaming data, providing a new method for people and machines to trade data on decentralized P2P networks. STREAMR provides a complete system. With this system, people can create unstoppable real-time data applications even without writing code. At present, the valuable data generated by users is manipulated by large companies. In the STREAMR network, you can use and sell data according to your needs, and roam among the decentralized P2P networks that are uncontrolled and motivated by datacoin tokens. Take the self driving electric vehicle as an example. In order to obtain the best driving experience, self driving electric vehicles need to collect data from other machines, such as traffic congestion information provided by other vehicles, electricity prices of nearby charging stations, weather forecast data, etc. STREAMR provides a unified interface for data delivery and payment, so that users can use datacoin token to trade data streams. Cars can independently obtain the required data and pay the corresponding data fees. At the same time, cars can also sell their own generated data (such as traffic data) to other vehicles, sell road condition measurement data to smart cities, and sell location and battery power data to advertisers. Data flow economy came into being.
