基于Hyperledger Fabric的汽车供应链系统的方案设计与性能分析

Design and Performance Analysis of Automotive Supply Chain System Based on Hyperledger Fabric

当前的汽车供应链体系一般采用中心化的管理模式,供应链中上下游企业间数据交互困难,信息不对称,因此造成了供应链运行效率低下。另外,信息的不透明也导致了供应链中的信任问题。为此,文中引入区块链技术,采用超级账本(Hyperledger Fabric)作为开发框架,设计了一个基于区块链的汽车供应链原型系统,旨在为多方企业提供安全可信的交易服务。该系统具备访问控制和数据透明、可追溯且不可篡改等特点,同时通过设计的多通道架构,实现了企业合作中的隐私隔离。文中使用docker技术构建了实验环境,对功能接口进行了测试,通过对原型系统吞吐量性能进行实验分析,验证了该原型系统的可行性。文中引入"区块链+"的模式为传统汽车供应链的升级与转型提供了新的思路。

Hitherto,a centralized management mode is prevalent in Automobile Supply Chain System(ASCS).The difficulty in data exchange and the information asymmetry between enterprises,nevertheless,are leading to a low efficiency in such system.Furthermore,critical question of trust is also raised due to the opacity of information.For these reasons,inspired by the emerging blockchain technology,a novel distributed blockchain-based ASCS with Hyperledger Fabric as a development framework is designed to provide secure and trusted transaction services for mutli-party enterprises.The proposed system is provided with a series of advantages,such as access control,Data transparency,traceable and non-modifiable.In addition,a multichannel architecture is devised to realize the privacy isolation in enterprise collaboration.In this paper,firstly,the experimental environment is constructed by utilizing the docker technology,and then the functional interface is tested.Finally,the feasibility of the proposed system is verified by analyzing the throughput performance.This paper introduces the model of“blockchain+”,which provides a new idea for the upgrading and transformation of traditional automobile supply chain.
