Abstract:
Purpose/Significance Achieving full traceability of wild agricultural products supply chain is of great challenge as they are grown widely and cannot be traced. To address this challenge, in this paper, we build a blockchain-based traceability system that leverages the information technologies such as blockchain and the Internet of Things. Design/Methodology Specifically, we propose a dynamic management method for member information authority to adapt to business activities in the agricultural products supply chain. We also design a “dual-track” data storage mechanism to cope with demand of the tamper proof and decentralized storage of multi-source and massive traceability data. We build traceability smart contracts supporting forward and backward traceability to locate the source information in the supply chain with large amount of mixing and splitting processes. Finally, we develop a front and back-end separated prototype software system for real-world application. Conclusions/Findings This study can provide a new solution to realize the traceability of the supply chain of high-value-added wild agricultural products by reducing the risk of product counterfeiting. It can help improve consumers’ trust in high-value-added wild agricultural products by making the supply chain information more transparent.
