基于联盟链的农业科学数据共享模型构建研究

Research on the Construction of Agricultural Science Data Sharing Model Based onConsortium Blockchain

[目的/意义]构建基于联盟链的农业科学数据共享模型,旨在推动农业科学数据共享进程,发挥农业科学数据的价值性。[方法/过程]在分析现有农业科学数据共享存在的问题的基础上,以问题分析为导向,从可溯源性、可共享性和安全性等三个维度探讨联盟链与农业科学数据管理适用性。[结果/结论]结合农业科学数据共享特点,构建基于联盟链的农业科学数据管理模型AgriDSM。该模型包括基于农业物联网的数据采集层、基于加密和云存储的数据存储层、基于Fabric联盟链的数据处理层和基于农业科学数据共享各个子系统的应用层。

[Purpose/Significance]The agricultural science data sharing model based on consortium blockchain is constructed,to promote the process of agricultural science data sharing and give play to the value of agricultural science data.[Method/Process]Based on the analysis of the existing problems in agricultural science data sharing,oriented to problem analysis,the applicability of consortium blockchain and agricultural science data management was discussed from three dimensions of traceability,shareability and security.[Result/Conclusion]Combined with the characteristics of agricultural science data sharing,the agricultural science data management model AgriDSM based on consortium blockchain is constructed.The model includes data acquisition layer based on Agricultural Internet of Things,data storage layer based on encryption and cloud storage,data processing layer based on Fabric consortium blockchain and application layer based on various subsystems of agricultural science data sharing.
