Agricultural food trade has a profound impact on social stability and sustainable economic development. However, there are several technological problems in current agricultural product and transactions.

For example, it is almost impossible to improve the efficiency of transactions and maintain market stability. This paper designs a novel Food Trading System with Consortium blockchain (FTSCON) to eliminate information asymmetry in the food trade, in order to establish a sustainable and credible trading environment, the system uses consortium blockchain technology to meet the challenge
of different authentications and permissions for different roles in food trade.

This paper proposes a mechanism based on an alliance chain that helps to eliminate information asymmetry and guarantee market fairness. The proposed system, based on blockchain technology, is shown to be effective for the food trade field. According to the Sustainable Food Trade Association, a highly reputed agricultural sustainable development organisation, the organic sector must integrate environmentally sound, socially just business practices using a systems-based approach to reach its full potential.

This paper has great academic significance for sustainable development research. In addition, it addresses trust issues in food trading because the proposed system ensures open transparency. For policymakers, FTSCON can better manage the food industry because it partly solves regulatory dilemmas.
