基于联盟区块链的铁路客运出行服务系统研究

Research on Railway Passenger Travel Service System Based on Consortium Blockchain

铁路客运出行服务系统需要与多个企业进行数据交互,各主体间存在缺乏信任、数据格式不统一、对账环节低效等问题,制约了铁路客运出行服务的发展。而区块链具有去中心化、不可篡改、全程留痕等特点,在铁路客运出行服务系统中引入区块链技术,有助于解决多方主体交易难题。在总结铁路客运出行服务系统现状的基础上,结合开源分布式账本平台Fabric的特点与优势,设计基于联盟区块链技术的铁路客运出行服务系统架构,并对系统的基本框架和业务流程进行了描述和分析,提出铁路客运出行服务系统中的数据共享、数据存储、数据安全、清分结算等关键技术,可以实现多方数据的可用不可见,提高合作企业参与的积极性,将为加快促进综合交通一站式出行服务平台建设提供研究支撑。

The railway passenger travel service system needs data interaction with multiple enterprises.However,there are some problems in the process,such as a lack of trust,inconsistent data format,and inefficient reconciliation among various subjects,which restrict the development of the railway passenger travel service.Blockchain features decentralization,non-tampering,and trace preservation in the whole process.The introduction of blockchain technology into the railway passenger travel service system will help to solve the transaction problems of multiple subjects.This paper first summarized the current situation of the passenger travel service system.Then,utilizing the characteristics and advantages of open-source distributed ledger platform Fabric,the paper put forward the architecture of the railway passenger travel service system based on consortium blockchain and described and analyzed its basic framework and business process.Finally,key technologies in the passenger travel service system were proposed,such as data sharing,data storage,data security,and clearing and settlement,which can realize the availability and invisibility of multi-party data,improve the participation enthusiasm of cooperative enterprises,and provide research support for accelerating the construction of onestop travel service platform of comprehensive transportation.
