Research on Cotton Supply Chain Quality Tracing Scheme Based on Blockchain Smart Contracts

The issue of quality traceability has been a persistent challenge in the current cotton supply chain, impeding the industry’s development. The lack of transparent and timely information transmission hampers effective regulation of cotton quality, thereby significantly impacting both the quality of cotton products and enterprises’ brand image. To address this problem, this paper proposes an Ethernet blockchain and smart contract-based platform for quality traceability in the cotton supply chain, enabling efficient management with complete transparency. We have developed five smart contracts and eight algorithms, providing comprehensive implementation, testing, and validation details for their integration into the cotton supply chain system. This approach ensures secure and authentic dissemination of quality information throughout the cotton supply chain while mitigating issues related to isolated product information.

I. Introduction

In recent years, with the steady growth of China’s cotton production year by year, high-quality cotton products play an increasingly important role in promoting the internal and external cycles of the textile industry. Among them, the cotton with low heterogeneous fibre content and good quality consistency is favoured by consumers and enterprises to an increasing extent^[1]. However, there are several problems in the implementation of the cotton traceability chain in China:
