Recently, the Intelligent Agriculture Innovation Team of the Institute of Agricultural Resources and Agricultural Regional Planning of the Chinese Academy of Agricultural Sciences (hereinafter referred to as the Institute of Capital Planning) cooperated with Madrid Polytechnic University in Spain, Swinburne University of Technology in Australia, and the Chinese Academy of Inspection and Quarantine Sciences to propose a blockchain-based food The retrospective framework is used to enhance the credibility of food trade between China and the EU, and the research results are published online in "Food and Energy Security". This paper is also the first international journal article to apply blockchain technology to agriculture after the relevant experts of the Chinese Academy of Agricultural Sciences put forward the blockchain agricultural application technology action proposal.
Qian Jianping, a researcher at the Institute of Capital Planning, said that food trade has become an important factor in meeting global food demand. Strengthening bilateral or multilateral food trade trust is of great significance for promoting the sustainable development of trade and enhancing in-depth cooperation in the context of the global food crisis. However, in many countries and regions, there is still a lack of credible traceability systems for cross-border food circulation. The blockchain is essentially a distributed public ledger, and its technical characteristics include decentralization, trustlessness, collective maintenance, and reliability. At present, the blockchain has developed into the 3.0 era, expanding from the financial field to digital finance, Internet of Things, intelligent manufacturing, supply chain management, digital asset trading and other fields. The Chinese Academy of Agricultural Sciences organized relevant experts to put forward a blockchain agricultural application technology action initiative, and took the agricultural product traceability blockchain as the primary development task.
The smart agriculture team has been focusing on the technical difficulties of blockchain technology in agricultural product traceability and agricultural resource management. The study took the food trade between China and the European Union as an example, and designed a conceptual framework; by making full use of the existing traceability systems of these two countries (regions), the characteristics of physical logistics, data flow and blockchain flow were analyzed. Considering the data capacity and the level of data privacy, a hybrid data storage method combining on-chain and off-chain is adopted; according to the characteristics of cross-border food trade, intelligence such as export data recording, inspection data recording and verification, retrospective query tracking, etc. are designed The contract proposes a blockchain-based interactive framework for traceability to increase trust in food safety in the food trade process. The blockchain-based credible traceability framework can enhance bilateral trust in cross-border food trade, and plays an important role in promoting the sustainable development of international food trade under bilateral or multilateral frameworks.
The research was jointly funded by the National Natural Science Foundation of China and the Science and Technology Innovation Project of the Chinese Academy of Agricultural Sciences.
