# Research on the Trusted Traceability Model of Taishan Tea Products Based on Blockchain
## 3 Design of Blockchain-Based Traceability Model for Taishan Tea
### Blockchain-Based Taishan Tea Traceability Process  
According to the above design ideas, on the basis of the traditional Taishan tea traceability model, combined with the process of the Taishan tea industry chain, the traditional centralized traceability system is reconstructed; based on the design idea of \"one link, one ledger\", the traceability data that need to be uploaded to the chain in each link are stored in separate ledgers, so as to establish a new distributed traceability system architecture. After extensive research on a number of representative enterprises, in-depth research on the Taishan tea industry, and field visits to related enterprises, we have systematically sorted out the complete process of Taishan tea from cultivation to production and elaborately drew a flowchart that comprehensively covers the complete process of Taishan tea from cultivation to processing. The flow chart summarizes the core operation steps of each key link and promotes a comprehensive understanding of the culture and industrial value of Taishan tea. The above is shown in Figure 2.  
The traceability process is summarized below:  
1. According to the traceability process of Taishan tea products, we divide it into five major links: planting, picking, processing, storage, and logistics. In each link, the steps involving the quality of Taishan tea products are regarded as the key factors affecting the quality of Taishan tea and need to be operated on the chain. This ensures that the entire production process of Taishan tea products is traceable, thus improving product quality and consumer trust. Figure 2: Taishan tea traceability process. 2. The planting link covers all the farming operations in the process of Taishan tea planting. During the planting process and before the harvesting of Taishan tea, agricultural products will be tested to ensure that Taishan tea meets safety and quality standards. The test results will be recorded and stored in the superledger of the planting process together with the data of agricultural operations, so as to facilitate subsequent inquiries and traceability. 3. Picking time has a profound impact on Taishan tea, which not only determines the quality characteristics such as tenderness, taste, aroma, and color but also directly relates to the yield and economic benefits of tea. In Taishan tea picking, the careful selection of buds and leaves is crucial, following the high standard of \"one bud, one leaf\", and picking at the best time in the spring to ensure the tenderness and uniformity of the tea, and thus enhance the overall quality of tea and market competitiveness. 4. Different types of Taishan tea require different processing methods due to their unique characteristics and flavors. The processing of each type of Taishan tea requires precise control of temperature, humidity, time, and other key parameters to ensure the quality of the final product. If there are missing steps in the processing process or if the processing method is not in place, the quality of the Thai tea leaves will be affected. The information generated from the processing needs to be uplinked and processed to ensure the quality and safety of Thai tea. 5. The warehousing link includes storage of tea species and environmental data. Tarzan tea is prone to a series of quality and safety problems in the storage link; therefore, the storage environment data of Tarzan tea are sensitive data of quality and safety. Consumers and enterprises can view the environmental data of the warehouse in real time, and consumers can also visually view the storage environment to improve the credibility of the product quality and safety, and, ultimately, the environmental data will be stored in the superledger of the storage link. 6. The logistics link includes data on the shipper, the transportation route of Taishan tea, and the receiver. These data not only track the physical location of the goods, but also provide important information for managing, monitoring, and optimizing the supply chain, providing strong support for decision-making. 7.
