# Research on the Trusted Traceability Model of Taishan Tea Products Based on Blockchain
## 3 Design of Blockchain-Based Traceability Model for Taishan Tea
### Design Ideas
Due to the limitation of the transaction speed of the alliance network, the short-term surge in transaction volume may lead to network blocking, which, in turn, affects the normal uploading of data and destroys the consistency and integrity of data. To effectively deal with this challenge, this paper innovatively proposes a hierarchical uploading mechanism. This mechanism aims to dynamically grade the data to be uploaded according to the importance and urgency of the data. By rationally deploying resources and prioritizing critical and urgent data, we can effectively avoid the blocking phenomenon of the alliance chain network while guaranteeing the timeliness and accuracy of data and ensuring the integrity and traceability of Taishan tea production data. The implementation of this mechanism will further enhance the reliability and practicability of the Taishan tea traceability model and provide strong support for the sustainable development of the Taishan tea industry. In our in-depth communication with Taishan tea enterprises, we have accurately identified and determined a series of key factors affecting the excellent quality of Taishan tea. In order to ensure the integrity, authenticity, and security of these valuable data, we adopt blockchain technology to collect these key factors directly through IoT devices, and, after strict screening and processing, securely upload and store them. This process not only guarantees the traceability of the data but also builds a solid digital cornerstone for the quality regulation and consumer trust of Taishan tea. We have mapped these in Table 1.  
The sources of non-uplinked data are wide and varied, and they may originate from the collection of IoT devices, or from the registration of information in the internal management system of the enterprise, which are mainly supplementary to the traceability information of Taishan tea and participate in the daily operation and decision-making of the enterprise; moreover, they are not directly involved in the key influencing factors that determine the quality and inferiority of Taishan tea. We plotted these data in Table 2. \begin{table}
\begin{tabular}{c c c} \hline \hline  & **Industrial Chain Link** & **Data Example** \\ \hline \multirow{6}{*}{Uplink Data} & \multirow{2}{*}{Planting} & Types of Tea Planted \\  & & Agricultural Operations \\  & & Pesticide Residue Detection \\  & & Picking Time \\  & & Picking Parts of The Tea Leaves \\  & & Processing Tea Types \\  & & Processing Method \\  & & Tea Types \\  & & Environment \\  & & Shipper \\  & Logistics & Transportation Routes \\  & & Recipient \\ \hline \hline \end{tabular}
\end{table} 
Table 1: Uplink data type. In order to improve the efficiency of Taishan tea data uploading and prevent network congestion, we plan to implement a data hierarchy strategy that prioritizes critical data that have a significant impact on tea quality, followed by the rest of the data. This strategy aims to ensure that critical information is recorded and shared instantly while reducing network pressure due to data deluge. Given the huge amount of data generated during the cultivation and production of Taishan tea, we focus on those data points that have a decisive impact on the quality of tea and propose to use blockchain technology to ensure that this critical information is tamper-proof and highly secure. In building a blockchain-based Taishan tea traceability model, we need to flexibly cope with the complex environment of concurrent use by using multiple enterprises, treating each production link as equally important and not presetting a fixed hierarchy of information grading. Instead, we will promote efficient and transparent sharing and tracing of the whole process of Taishan tea information among all participating enterprises through a refined data processing mechanism, so as to jointly guard and enhance the quality and brand value of Taishan tea.
