摘　　要：为解决现有的代码共享航班信息系统分布于各个航司与GDS,存在信息不一致的问题,提出了一种基于区块链改进的代码共享航班管理系统模型。改进模型在保证原系统功能的基础上,增加区块链系统的支持,将交易的用户信息及数据的摘要上链,来保证系统的不可窜改特征。并提出四次交互的消息验证机制,将改进系统中涉及业务变更的信息进行抽象并规范化。对实现的系统进行时间及空间两个维度的测试。结果表明,系统具有可扩展性,并有着较好的吞吐量及可预估的空间占用,符合企业级信息系统上链要求。In order to solve the problem that the flight information inconsistency distributed in various airlines and GDS system,this paper proposed an improved code-sharing flight management system model based on blockchain.The improved model increased the support of the blockchain system on the basis of ensuring the functions of the original system,and uploaded the user information and data summaries of the transaction to the chain to ensure the non-tampering characteristics of the system.The improved model could increase the support of the blockchain system on the basis of ensuring the function of the original system,and registered the user information and data summary of the transaction on chain to ensure the system’s tamperability.Meanwhile,it proposed a message verification mechanism of four interactions to abstract and standardize the information related to business changes in the improved system.The implemented system was tested in both time and space dimensions.The results show that the system is scalable,has good throughput and predictable space occupation,and meets the requirements of enterprise-level information system on-chain.
