Agricultural Cold Chain Logistics Mode Based on Multi-Mode Blockchain Data Model

Abstract

Aiming at the problem of massive data storage and transaction authority in the blockchain system in the data sharing transaction scenario, this paper proposes a blockchain system for the controllable sharing transaction of massive data. By designing the blockchain system model of the consortium chain and private chain, reconstructing the data structure of the block, and introducing the InterPlanetary File System (IPFS) technology, we adopt the off-chain storage method to solve the problem of high cost caused by too much data carried by the block. The isolation control of data resource transactions is realized by introducing identity authentication and channel mechanism, which meets the needs of different subjects for confidentiality of transaction data information. From the analysis results of cold chain logistics efficiency, in the five years from 2017 to 2021, the comprehensive cold chain logistics efficiency, pure technology cold chain logistics efficiency, and scale cold chain logistics efficiency of agricultural product cold chain logistics in a certain region have all reached above 0.9. The return to scale remains unchanged, and the cold chain logistics resources have been effectively allocated and reasonably utilized. The value of comprehensive cold chain logistics efficiency, pure technology cold chain logistics efficiency, and scale cold chain logistics efficiency in a certain month is less than 1, which means that the cold chain logistics efficiency is weak or ineffective. This shows that in these years, the infrastructure investment, cold chain technical support, and management level related to the cold chain logistics of agricultural products in a certain region need to be strengthened, and it is necessary to adjust the input-output structure and allocate resources reasonably. From 2018 to 2021, the total factor productivity of agricultural product cold chain logistics in a certain region is greater than 0.85, indicating that the level of total factor productivity is relatively high during this time period, and the increase in the efficiency of technical cold chain logistics is the main reason for the increase in total factor productivity.

How to build a cold chain supply chain system for fresh agricultural products through blockchain technology—A study of tripartite evolutionary game theory based on prospect theory

“…Although China’s cold chain logistics has made apparent progress in terms of industrial scale, development quality, innovation pace, and market competitiveness. However, development is hampered by various issues, such as a lack of standards in some areas of cold chain logistics, the low level of cold chain technology [ 38 ], outdated cold chain equipment [ 39 ], an unsound cold chain logistics system in large and medium-sized cities [ 40 ], the lack of an agricultural logistics information platform [ 13 ]. Thus, there is no way to guarantee a constant cold temperature along the whole supply chain of cold chain logistics.…”

A Literature Review of Blockchain-Based Applications in Supply Chain

“…A blockchain system for controlled shared transactions of massive data is proposed by Si [49]. the system divides the blockchain module into two parts, consortium chain, and private chain.…”

“…In the traceability system, when a large number of IoT devices are deployed, data leakage may occur, and the relevant scoring mechanism is proposed accordingly. Paper [48][49][50][51] makes different transactions by establishing channels to ensure that the data will not be leaked to the outside. However, this method is similar to building a new blockchain, which requires a lot of costs, so the implementation of the idea is doubtful.…”
