Abstract
Agricultural data management plays an important role in the development of agriculture and even the national economy. Data has been written into the national documents as a factor of production, and its importance is not strict. As the technical support of agricultural data management, blockchain, big data and Internet of Things technology drive the rapid development of agricultural data management. In this paper, the application of blockchain in agricultural data management in the past five years is described in a panoramic manner by using data visualization method. At the same time, content analysis is carried out based on literature content, and the research status at home and abroad is summarized. 92/5000. Through analysis, it is concluded that the application of blockchain technology in agricultural data management mainly includes blockchain + agricultural Internet of Things mode, blockchain + agricultural supply chain mode, blockchain + agricultural data sharing mode, etc. In the future, we need to further expand the application mode of blockchain technology in agricultural data management.
Highlights
Agricultural data is an important part of data
This paper mainly studies the application of blockchain in agriculture data management, because in order to blockchain + agricultural data management as the theme of the data is very little, not enough to make a visual knowledge map, so this paper expanded the scope, to journals in CNKI database as the data source, with “blockchain + agriculture” as keywords retrieval, got 173 data, research hotspots include agricultural Internet of Things, agricultural products, artificial intelligence, decentralization, smart contracts, big data, smart agriculture, food safety, traceability, agricultural supply chain, rural revitalization, consensus mechanism, agricultural big data, rural finance, etc
In terms of agriculture data sharing, document types are mainly concentrated in the patent literature, patent literature is focused on the precision, such as: one based on blockchain agricultural data sharing method, a kind of agricultural data sharing system based on blockchain, a method based on blockchain of agriculture data acquisition and sharing system, a kind of agricultural data sharing system and the method based on blockchain, etc
Summary
When we manage agricultural data in the whole life cycle, we use many key technologies, such as big data sharing technology, blockchain technology and cloud storage. Blockchain technology can reduce asymmetric access control of information, and all blockchain participants get the same information Applied to distributed computing and distributed data sharing and storage, we need to seize technological opportunities to accelerate the process of agricultural data management and encourage agricultural organizations to continue to innovate and develop distributed ledger technology solutions. The Chinese database is used as the data source for keyword co-occurrence analysis, to find out the main research hotspots in the field, and find out the research topics of highly cited papers and hot papers, and the application of key technologies in agricultural data management
