# Research on Flexible Traceability System of _Agaricus bisporus_ Supply Chain
## 5 Discussion  
Based on on-site research at a modern _Agaricus bisporus_ factory, this paper conducts an in-depth analysis of various links in the _Agaricus bisporus_ supply chain. By combining the differentiated requirements of traceability subjects including consumers, enterprises, and regulatory authorities, a trustworthy traceability system architecture for _Agaricus bisporus_ quality and safety is constructed. This includes the deployment of the Hyperledger Fabric environment and the development of smart contracts. The logical design of the system is outlined through the on-site research plan, demonstrating the operation of the trustworthy traceability system for _Agaricus bisporus_ quality and safety. The following are two key points to consider. Intra- and inter-firm challenges: Internally, companies must overcome challenges such as inadequate technical expertise and facility limitations, necessitating significant resource allocation to ensure the system operates efficiently. Additionally, it is crucial for companies to invest the requisite time and resources in employee training and to safeguard data accuracy, integrity, and confidentiality to enhance credibility. Externally, implementation between companies requires addressing issues like partner compliance, ensuring transparency in information sharing, and establishing uniform data standards. This involves fostering a relationship of mutual trust, clarifying the allocation of risk and responsibilities, and collectively driving the smooth implementation and operation of the traceability system. The challenges in technical and system management aspects: In the process of system implementation, ensuring data security and privacy protection is of paramount importance, especially when dealing with sensitive information. Corresponding protective measures are imperative. Additionally, maintaining and promptly updating the system to adapt to new demands and technological advancements is crucial. However, introducing new technology or upgrading existing systems necessitates a substantial investment of resources, including funds and human capital. Therefore, businesses need to adopt appropriate strategies and measures in the realms of technology and systems to ensure their effective operation and sustained development. From the perspective of consumers and society, this system enhances consumer trust and confidence in the products, allowing them to accurately understand the production source, quality, and safety information. It aids in swiftly identifying and resolving product quality and safety issues, thereby safeguarding the health and safety of consumers. Additionally, the system encourages consumers to actively participate in product quality supervision and feedback, enhancing their sense of involvement and prompting companies to continually improve product quality standards.

Firstly, it enables companies to precisely trace the fundamental causes of product quality issues, facilitating targeted improvements and enhancing overall product quality. Secondly, by swiftly locating and recalling affected products, the system reduces the time and cost involved in crisis management, effectively lowering enterprises' risks. Furthermore, the implementation of a traceability system underscores a company's heightened emphasis on product quality and safety, thereby bolstering its brand image and reputation. The system furnishes more accurate data and information, aiding in the optimization of supply chain management and operations, thereby elevating overall efficiency and laying a solid foundation for the sustainable development of enterprises. Currently, our team has conducted some preliminary experiments at Shandong Century Smart Agriculture Technology Co., Ltd. (Weifang, China), focusing mainly on _Agaricus bisporus_ supply chain data collection technology and the development of a flexible traceability system.
