区块链交易安全问题研究

Research on blockchain transaction security

区块链技术提出了去中心化的分布式账本,改变了原有的交易模式。然而新模式的出现和发展带来了许多交易安全问题,严重威胁用户资产安全。首先对区块链交易进行简要概述,再重点研究分析区块链交易的安全问题,包括攻击、骗局、账户行为、私钥泄露和智能合约漏洞等,接着,从交易记录异常检测、地址异常检测、智能合约检测、行为异常检测以及智能合约漏洞检测工具5个方面叙述区块链交易安全检测的方法,最后对区块链交易安全的发展进行了展望。

A blockchain technology is proposed for the decentralized distributed ledger,changing the original transaction mode.However,the emergence and the development of the new mode bring many transaction security problems,seriously threatening the security of user assets.Firstly,a brief overview of blockchain transactions is given and then the security issues of blockchain transactions are analyzed,including attacks,fraud,account behavior,private key leakage,and smart contract vulnerabilities,etc.Then,blockchain transactions are described from five aspects:transaction record anomaly detection,address anomaly detection,smart contract detection,behavior anomaly detection,and smart contract vulnerability detection tools.Finally,the full text is summarized and the development of blockchain transaction security is prospected.
