面向智慧水务平台的区块链BaaS关键技术

Key Technologies of BaaS for Smart Water Management System

传统水务数据大多以中心化管理模式为主,但是数据权益涉及到水务集团、设备生产商和保险公司等.在此前提下,数据是否可信,数据传输和存储过程中是否被篡改成为利益涉及方痛点问题与面临的挑战.针对上述问题和挑战,本文结合区块链技术去中心化、不可篡改、可追溯的特性,提出了一种智慧水务区块链BaaS(Blockchain as a Service,区块链即服务)的构建思路和方法,较好地解决了水务数据所面临的可信度低问题.对BaaS服务关键技术:(1)BaaS服务体系架构;(2)智能水表健康数据分布式账本数据模型和Merkle二叉树验证模型;(3)基于双缓冲队列和多区块链节点接入的关键技术,进行了较为详细的阐述.

Most of the traditional water data are subject to centralized management,but the rights and interests of the water data are related to water groups,equipment manufacturers,and insurance companies.Then whether the data is tampered during transmission and storage has become a challenge to stakeholders.In view of the above problem,we propose a method for the implementation of intelligent water Blockchain as a Service(BaaS)according to decentralized,unforgettable,and traceable Blockchain technology,avoiding unreliable water data.In addition,we expound the key technologies of BaaS,including the BaaS service architecture,the distributed ledger data model and the Merkle binary tree verification model of health data from intelligent water meters,as well as double buffer queue and Blockchain-based multiple access nodes.
