Abstract: The development and application of blockchain technology can solve the problem of inconsistent quality levels in the physical delivery of current wheat futures transactions. This study takes wheat futures as the research object, and builds a wheat futures trading platform based on blockchain technology by analyzing the quality problems of wheat futures trading and the applicability of blockchain technology. Then, the conceptual model and quality control scheme of wheat futures trading quality evaluation process based on blockchain are proposed from the three stages of data acquisition, physical delivery and quality feedback. Thus, the quality evaluation system of wheat futures based on blockchain is constructed to provide reference for ensuring the quality of wheat futures trading and promoting the healthy development of wheat futures trading market.
