【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.

【标题】考虑Viniar算法的农业电子商务信息溯源中的双链区块链

【摘要】本文考虑Vennia算法对双链区块链农产品电子商务信息溯源进行深入研究和分析。本文在溯源系统中增加协同验证模块，针对农产品供应链的特点，对农产品信息存储、溯源共识算法、智能合约进行详细设计，其中协同验证模块采用动态数据存储技术；对ConsideVinia共识算法进行改进，引入积分惩罚机制的方式，保证区块数据的有效性。本文在对比研究了三大区块链技术平台的特点和差异后，选择超级账本实现基于区块链技术的农业溯源系统，将分区和信用机制引入到ConsideVinia算法中，并阐述改进过程的算法。改进后的算法在保持区块链一致性的同时，通过信用机制减少节点的恶意行为，维护系统安全。如发生交易纠纷，第三方平台将根据交易记录等证据确定过错方，并作出相应的处罚和赔偿。实验证明，本文提出的算法可以减少节点共识过程中的网络数据传输量，无论是吞吐量还是延迟都优于ConsideVinia算法，提高共识效率，缓解通信瓶颈由于区块链应用用户的增加，将区块链技术应用于农产品溯源系统的解决方案是切实可行的。基于区块链的农产品信息溯源系统解决了传统的基于物联网的农产品溯源系统信息不对称、难以共享、易篡改、存储集中等问题，真正实现了农产品全链条的可信可追溯。信息。本文的研究内容和结果具有一定的理论和实践价值。
