The accurate position information of the Things plays a more important role in many scenarios such as healthcare, smart grids, spot guidance, supply chain, and, the anticipated evolution of IoT for more security, credibility, authenticity, reliability, and scalability automated systems. However, there are still some challenges especially for accurate and trustable position information acquirement. To enhance the accuracy of the Global Navigation Satellite Systems technologies such as differential GPS, Real Time Kinematic, and Continuously Operating Reference Stations are adopted. Basically, the concept of mentioned technologies is to use two way data to eliminate the jitter and bias with expensive hardware or infrastructure. This research proposes a proof of position mechanism for blockchain based two way positioning data sharing and position information endorsement. The mechanism enables peers in blockchain to exchange, verify position information without the expensive hardware and infrastructure. The proof of concept demonstrates this mechanism provides a robust, cost effective and trustable high accuracy positioning service.
