摘　　要：分析了以区块链、对等节点(P2P)架构、记账权争夺、共识机制等技术体系为核心而构成的系统的应用场景和特点,阐述了这类系统以巨大地浪费系统的运算能力和电能为代表的3条缺点.针对不同的应用场景,为了克服这些缺点,设计了新的系统架构、随机授权机制和整个系统的运行机制.简述了强中心架构和对等节点架构,论述了它们的使用场景和优缺点.设计了在管理节点有一定的信用度但仍需要在互相监督的场景中使用的监督架构和处理监督架构,使用了SM2或ECC算法确保数据传输的私密性与安全性.分析了处理监督架构中的工作数据流程,设计了该系统中的数据区块结构和区块链,提出了双哈希认证与随机授权(RA)技术.设计了核准发布过程和签名验证方法,论述了基于现实世界中的信用度而获得管理节点的方式.得出了在适当的使用场景下,该设计可以克服原来系统的3项缺点的结论.The application scenarios and the characteristics of the technology system?which is mainly composed of blockchain,peer-to-peer(P2P)framework,recording authorization competition and consensus mechanism,are analyzed in this paper.The disadvantages of the system are expounded,which include a huge waste of computing capability and electricity power.In order to overcome these shortcomings>a new system framework,a random authorization mechanism and the operating mechanism of the whole system are designed.The strong center framework and the peer-to-peer framework are discussed,of which the advantages and disadvantages and the application scenarios are also discussed.The monitoring framework and the processing monitoring framework are designed,which are used in the scenarios that management nodes can be partly trusted but should be supervised.The SM2or ECC algorithm is applied in order to ensure the privacy and security of data transmission.The data flow in the processing monitoring framework is analyzed.The data block structure and blockchain in this system are designed.The double hash authentication and random authorization(RA)technology are proposed.The approval release process and the signature verification method are designed.The method of obtaining management nodes based on the credit of the real world is discussed.This paper concludes that the three shortcomings of the original system can be overcome in this design in the appropriate scenario.
