摘要
区块链具有去中心化、数据不可篡改、分布式账本的特性,在未来众多行业中有着广泛的应用前景.但在高校联盟链场景中会遇到交易高并发的问题,本文提出使用具有高并发特性的有向无环图DAG(Directed Acyclic Graph)数据存储结构,修改单元结构,加入消息积分、实名验证和投票三种消息类型,实现节点信用积分和实名认证.通过模拟实验证明系统具有较高安全性,能够抵御常见的双花攻击、伪造交易信息和伪造共识节点网络攻击,适用于高校联盟链场景.
The blockchain has the characteristics of decentralization,data cannot be tampered with,and distributed ledgers.It has a wide range of application prospects in many industries in the future.However,in the university consortium chain scenario,the problem of high transaction concurrency will be encountered.This paper proposes to use the Directed Acyclic Graph(Directed Acyclic Graph)data storage structure with high concurrency characteristics,modify the unit structure,add message points,real-name verification and There are three message types for voting to realize node credit points and real-name authentication.Simulation experiments show that the system has high security and can resist common double-spending attacks,forged transaction information and forged consensus node network attacks,and is suitable for university alliance chain scenarios.
