Blockchain-based application for grain production and trade: a case study of Huzhou storehouse tender mode, China

Grain security is vital for achieving Sustainable Development Goals and is a top national priority in China. To address natural disasters and emergencies, China has maintained a grain reserve system for decades. However, the current system faces issues in reservation efficiency and grain quality, risking waste in the grain industry. In order to solve these problems, in 2018, Huzhou City initiated an experiment named storehouse tender mode (STM) to improve the grain reserve system in production and trade. This paper provides an overview of STM, explores efficiency and security issues within the grain reserve system, and introduces a blockchain-based prototype system designed to bolster STM implementation. The system simulation highlights blockchain's potential to establish a transparent, traceable, and trustworthy trade environment for STM. Findings confirm the feasibility and optimisation capacity of the proposed solution, signalling a transformative potential for the traditional grain reserve system.
