    摘要:

    基于中央服务器的传统架构是过去后台服务搭建的重要解决方案, 但随着用户数与应用需求的爆发式增长, 该架构对中心节点的计算与存储能力提出了更高的要求, 同时也带来了信任危机. 分布式系统的一个典型代表-区块链, 作为比特币的核心技术, 它的不可篡改, 可追溯, 不可伪造数据等特性使得它在近几年受到广大研究者的广泛关注. 本文提出将联盟区块链应用到电动车, 充电桩, 智能电表, 传输电网所组成的充电网络中, 利用区块链技术来管理充电记录, 以此来保护每一方的利益, 为交易纠纷的解决提出一种数据层面的支撑. 本文在提出专用联盟区块链的同时, 也提出了一种新的适用于电动汽车可信充电模型的共识机制和对应的查询智能合约. 实验结果表明所设计的共识机制能在该可信充电网络模型中安全高效的运行, 同时也能够满足用户快速查询交易的需求.

    Abstract:

    The traditional architecture based on a central server is an important solution for the construction of background services in the past. However, with the explosive growth of the number of users and application requirements, this architecture has put forward higher requirements for the computing and storage capabilities of the central node and brought a crisis of confidence. A typical representative of distributed systems, namely, blockchain, is the core technology of Bitcoin, and it has been widely concerned by researchers in recent years due to its characteristics such as tampering prohibition, traceability, and forgery data prohibition. This study aims to apply the consortium blockchain to the charging network composed of electric vehicles, charging piles, smart electric meters, and transmission networks and use blockchain technology to manage charging records, so as to protect the interests of each party and provide transaction disputes with data-level support. In addition to a dedicated consortium blockchain, this study also proposes a new consensus mechanism and a corresponding smart query contract suitable for the trusted charging model of electric vehicles. The experimental results show that the designed consensus mechanism can operate safely and efficiently in this trusted charging network model and can make users quickly search for transactions.
