Design of Remote Sensing Image Sharing Service System Based on Block Chain Technology

Block chain is a newly emerging technology for data sharing and application. It can exchange de-centralized information in distributed systems without mutual trust by means of data encryption, timestamp and distributed consensus, so as to improve the efficiency of data sharing and application. This technology can be fully utilized in the large data remote sensing image system, and the multi-system shared node storage system can be managed efficiently and uniformly, so as to improve the economic efficiency of the system. This paper designs the shared architecture based on block chain technology, proposes key research technologies, and provides theoretical basis for nonengineering practice.
