Design and Evaluation of a High-performance Support System for Credibility Tracing of Agricultural Products

Abstract

The data credibility tracing for agricultural product transactions is affected by all organizations in the entire supply chain. For traditional centralized product transaction management, the data are only stored in one organization in the supply chain, making transaction data management non-transparent and not credible. However, blockchain connects transaction information blocks into a tamper-proof and distributed chain ledger by Hash Function, which can help solve the problem. But the data access performance in blockchain still needs improvement. With Hyperledger Fabric as the underlying technology of the decentralized tracing system for agricultural products, and through improving system performance by Redis-based data structuring method, this study designed and implemented a complete chain tracing system from production, processing, package and logistics to sales of agricultural products. The study program not only introduced the design program and technological architecture of this system, but also evaluated the system performance under single-node and multi-node server environments. The experiment results show that the program integrating Hyperledger Fabric and Redis has a data access speed at least four times faster than that without Redis, especially for multi-node server, in which the performance improvement is over 20 times. Therefore, this design program can offer a feasible approach for improving system performance of the credibility tracing system of agricultural products.
