Abstract The development of modern science and information technology has promoted social progress and created better conditions for the realization of smart agriculture. The core of smart agriculture is big data, but the current big data management model still has certain hidden problems. The application of block chain technology can better realize the sharing of agricultural data. This article is based on block chain technology to study agricultural data sharing and sustainable development of ecological environment. This article conducts an in-depth analysis of the advantages of block chain-based big data sharing, and establishes a block chain-based big data sharing model. In order to improve the problems of significant regional and independent information of major agricultural information websites, this article also analyzes the agricultural data sharing technology, develops an agricultural information sharing system combined with the cloud computing platform, and links the characteristics of agricultural data to common data integration and the sharing method has been improved. According to the experimental data in the agricultural information exchange platform, users' attention to agricultural product production data is as high as 26.2%, and their attention to agricultural consumption accounts for 25.6%. It can be seen that many users are willing to complete the exchange of agricultural data on the platform. A cross-regional agricultural information exchange platform can improve the scattered distribution of agricultural data in the past, and provide agricultural production decisions for users in need through data analysis, and promote the sustainable development of agricultural economy. The innovation of this article is to make full use of blockchain technology to realize agricultural data sharing and sustainable development of the ecosystem. Through the combination of quantitative analysis and qualitative analysis, theoretical research and empirical research, it highlights decentralization from multiple angles. The mechanism can actually solve agricultural problems and achieve ecological sustainable development.
