基于区块链技术的土建工程项目管理平台

A Civil Engineering Project Management Platform Based on Blockchain Technology

每个土建工程项目其工程浩大,流程复杂,且偷工减料、以次充好、造假数据、权钱交易获得工程承包权等暗箱操作事件时有发生。因此加强并完善土建工程项目的管理体系对土建工程顺利开展,提高工程的整体质量具有重要意义。区块链技术的去中心化、去信任、信息透明、数据不可篡改可溯源等特征可一定程度上提高工程项目的安全性、降低工程事故的发生率。针对当前土建工程项目管理的痛点,文中提出了一种基于联盟区块链的土建工程项目管理平台CEPM-Chain,探索了智能合约应用以及将该技术与土建工程信息建模和信息管理相结合的可行性,利用区块链技术提高土建工程行业项目管理的流程效率。阐述了该系统的架构设计,并介绍了共识层的优化设计,采用节点角色分工、信誉度机制、随机话语权增加等方法降低其通信复杂度,提高其可拓展性,优化了该系统的性能。

Each civil engineering project has a huge amount of engineering,complicated processes,and black-box operations such as cutting corners,shoddy materials,falsifying data,and obtaining engineering contracting rights through rights and money transactions,etc.happen from time to time.Therefore,strengthening and perfecting the management system of civil engineering projects is of great significance to the smooth development of civil engineering projects and improving the overall quality of the project.The characteristics of blockchain technology such as decentralization,trustlessness,information transparency,and non-tamperable and traceable data can improve the safety of engineering projects and reduce the incidence of engineering accidents to a certain extent.Aiming at the current pain points of civil engineering project management,we propose a civil engineering project management platform CEPM-Chain based on alliance blockchain,exploring the feasibility of application of smart contracts and combining it with civil engineering information modeling and information management,and using blockchain technology to improve the process efficiency of project management in the civil engineering industry.The architecture design of the system is explained,and the optimization design of the consensus layer is introduced.The method of node role division,reputation mechanism,random voice increase and other methods are used to reduce the communication complexity,improve its scalability,and optimize the performance of the system.
