Design of Transaction System for Remote Sensing Cloud Service based on Blockchain
2019
With the development of RS (Remote Sensing) technology and RS application, RS industry is faced with opportunities and challenges in expanding the application fields. There is a high maintenance costs, time-consuming, low transaction processing efficiency, user privacy leaks and so on in the traditional centralized RSCS (Remote Sensing Cloud Services) trading mode. Meanwhile, it can't adapt to high-frequency and real-time trading scenario. In order to realize efficient, fair and transparent trade and protect the privacy of users, this paper proposed transaction system mode for RSCS based on blockchain. The user may call or produce the same task multiple times in the traditional transaction process. In this case, the system allocates and recycles resources frequently. It has caused unnecessary overhead and wasted the time of user. Therefore, we proposed AS (Algorithm Service) transaction mode combine smart contract. We can achieve decentralized P2P trade among through smart contract. The AS can reduce user's repetitive work, improve the efficiency of transaction processing, and improve user experience.
