"Fysical is the infrastructure for the transparent and compliant exchange of location data; foot traffic sensor readings, store visit information, commute routes. Fysical allows data suppliers to share and monetize their location data, while maintaining transparency, ownership, and control. At the same time, Fysical provides data buyers with the optimal way to access and validate data and its source. Fysical directly contrasts with today's closed systems, data brokers, and black boxes, and replaces them with a transparent peer-to-peer blockchain protocol. "
