摘　　要：钢铁企业全流程数据的有效管理是实现实时决策的保障.现有全流程数据管理系统中心化严重,导致容灾性和安全性弱、效率低.本文利用区块链技术,对其账户机制进行改进,设计了钢铁全流程数据管理方案.首先,描述了全流程数据管理的业务需求和难点;其次,采用实用拜占庭容错(practical Byzantine fault tolerance, PBFT)共识机制和智能合约技术,设计了基于联盟链的全流程数据管理系统结构模型;然后,针对传统区块链账户只有一种资产的弊端,提出了一种新的资产账户管理机制——多种资产账户,进而提出了相应的账户内资产转化算法和账户间资产交易算法;最后,对系统特征和效率进行了对比分析.结果表明,该系统与传统的中心化系统相比,安全性和容灾性较强,效率较高.The effective management of whole process data in iron and steel enterprises guarantees the realization of real-time decision-making. The centralization of the existing whole process data management systems is serious, resulting in weak disaster recovery and security and low efficiency. Using blockchain technology to improve its account mechanism, a scheme of iron and steel whole process data management is designed. Firstly, the business requirements and difficulties of whole process data management are described. Secondly, practical Byzantine fault tolerance(PBFT)consensus mechanism and smart contract technology are adopted to design the structural model of the whole process data management system based on the alliance chain. Thirdly, in view of the disadvantage that traditional blockchain accounts have only one kind of asset, a new account mechanism—multiple asset account is designed, then the corresponding asset conversion algorithm in the account and asset transaction algorithm between accounts are proposed. Finally, the characteristics and efficiency of the system are compared and analyzed. The results show that compared with the traditional centralized system, the system has stronger security, stronger disaster tolerance and higher efficiency.
