Dual-Chain Blockchain in Agricultural E-Commerce Information Traceability Considering the Viniar Algorithm

Abstract

In this paper, we consider the Vennia algorithm to conduct in-depth research and analysis on the traceability of dual-chain blockchain agricultural products' E-commerce information. This paper adds a collaborative verification module to the traceability system and carries out a detailed design of information storage, traceability consensus algorithm, and smart contract for agricultural products according to the characteristics of the agricultural products supply chain, among which the collaborative verification module adopts dynamic data storage technology; the ConsiderVinia consensus algorithm is improved by introducing the way of integral penalty mechanism to ensure the block data validity. After a comparative study of the features and differences of the three major blockchain technology platforms, this paper selects the super ledger to implement the agricultural traceability system based on blockchain technology, introduces the partitioning and credit mechanism into the ConsiderVinia algorithm, and elaborates the improvement process of the algorithm. The improved algorithm reduces the malicious behavior of nodes and maintains the system security through a credit mechanism while maintaining the consistency of blockchain. In the event of a transaction dispute, the third-party platform will determine the party at fault based on the transaction records and other evidence and make corresponding punishments and compensations. The experiment proves that the algorithm proposed in this paper can reduce the amount of network data transmission in the process of node consensus, which is better than the ConsiderVinia algorithm in terms of both throughput and latency, improves the consensus efficiency, and alleviates the communication bottleneck caused by the increase of users in blockchain applications, and the solution of applying the blockchain technology to the agricultural products traceability system is practical and feasible. The blockchain-based agricultural products information traceability system solves the problems of information asymmetry, difficult sharing, easy tampering, and storage centralization in the traditional IoT-based agricultural products traceability system and truly realizes the credible and reliable traceability of the whole chain of agricultural products information. The research content and results of this paper have certain theoretical and practical values.

Information Traceability Model for the Grain and Oil Food Supply Chain Based on Trusted Identification and Trusted Blockchain

“…As an important means of carrying information directly and effectively, identification technology is self-evident in the importance of information tracking and traceability in the whole supply chain of grain and oil food [ 21 , 22 ]. How to effectively track and trace the data generated by the cultivation, processing, warehousing, logistics, retailer and other participating links in the whole grain and oil food supply chain and ensure the real-time, safety and reliability of the data in the traceability system has become a research hotspot in recent years [ 23 ].…”

Enhanced Multiset Consensus Protocol Based on PBFT for Logistics Information Traceability

“…Te data can be added to the blockchain database [29]. References [30][31][32][33] all use the consensus algorithm of blockchain technology to realize the traceability query of logistics information. Te following focuses on analyzing the research status of the PBFT consensus algorithm.…”

Profit Coordination and Optimization of Agricultural Product Brand Promotion Lead by Farmer Cooperative Organizations

“…Scholars generally believe that the operation of agricultural e-commerce is infuenced by blockchain technology, logistics service levels, and agricultural preservation technology [29]. Te application of technologies such as blockchain [30] and the Internet of Tings [31] has afected the level of information technology [32,33], quality traceability [34,35], and electronic marketing [36,37] of agricultural products, thereby improving the circulation efciency of agricultural products and reducing their costs. Logistics services [18,38], especially cold chain logistics [27,39], and the greenness and freshness of agricultural products [40][41][42] have a signifcant impact on the online sales evaluation of agricultural products [43].…”
