# A Blockchain Solution for Remote Sensing Data Management Model
## 1 Introduction
Currently, the blockchain still has the problem of the difficulty in storing remote sensing data in the blockchain, which is also a difficulty in the combination of blockchain technology and remote sensing data sharing. Remote sensing data are large-scale and high-dimensional, and contain significant geographic spatial information. Storing such data on the blockchain may pose limitations regarding the storage capacity. Additionally, remote sensing data often involve sensitive geographic spatial information, such as terrain and land use. The decentralized and transparent nature of a blockchain may raise concerns regarding privacy and security. While a blockchain can provide a certain level of data protection through encryption techniques, challenges related to data privacy and security still need to be addressed. To overcome these issues, there are potential solutions, such as multichain and access control mechanisms. The distributed ledger of a blockchain can trace and verify the source and integrity of remote sensing data. Through the utilization of smart contracts and the consensus mechanism of a blockchain, a decentralized system for assessing the quality of remote sensing data can be established. Participants can submit their assessment results and reach consensus through the consensus algorithm. This can enhance the reliability of the data and reduce the inaccuracies caused by individual errors or malicious attacks. To summarize, this paper intends to make full use of the advantages of a blockchain to research remote sensing data sharing methods, by taking advantage of a blockchain's decentralized, secure, and reliable features, and preventing tampering. Addressing the question, this article on the chain architecture and the block of data structure, on the one hand, will improve the existing blockchain model, according to the business functions of the internal need to build more chain structures and, on the one hand, design and build a data interoperability information model, using the research content of the traceability of the production process, and the block storage model, to form an efficient and distributed remote sensing data blockchain storage scheme, to ensure data security and efficient access. The decentralized, secure storage and sharing of remote sensing data based on a blockchain will facilitate reliable sharing of remote sensing data around the world, help more people to participate in, and access, geospatial information services, and help spread geospatial information more widely. This will lay the foundation for the reconstruction of spatial data facilities, and provide data and technical support. The purpose of this paper is to address the issues of storage centralization and the centralized verification of data integrity services in cloud storage scenarios, while maintain ing a balance between safety and high performance. To accomplish this, a secure storage solution for remote sensing product data based on multiple blockchains is proposed, and a prototype system is developed for experimental validation. This paper is organized as follows. Section 2 analyzes the relevant issues and work. The specific remote sensing data interoperability system architecture and the block data structure applied to the remote sensing production chain are introduced in Section 3. Section 4 introduces the realization of the prototype system and related experiments, and analyzes the experimental results. Section 5 discussion the potential drawbacks and limitations to this approach. Finally, conclusions and discussions of future work are presented in Section 6.
