区块链的应用：安全威胁与解决策略

The Application of Blockchain:Security Threats and Solutions

区块链技术具有去中心化、可追溯性和去信任化等特性,已被广泛应用于诸多领域。然而,人们往往忽略区块链自身的安全问题,较少有相关问题研究及解决方案的成果。文章着重剖析区块链所受安全威胁问题并提出其安全保护措施,从技术风险、内容风险等不同视角阐释区块链所受的安全攻击,在多个层面给出了区块链的安全保护机制,尤其对日蚀攻击防御中IP地址信用评价模型进行了思索。最后,从技术和监管两个方面,对区块链技术的发展进行了展望。

Blockchain technology has the characteristics of decentralization,traceability and detrust,and has been widely used in many fields.However,attention to the blockchain’s own security issues is often overlooked,and fewer relevant research and solution results are published.This paper analyzes the security threats of blockchain and gives security protection measures.Firstly,it explains the security threats of blockchain from different aspects such as technical risk and content risk.Secondly,the security protection measures of blockchain are given at multiple levels,and the IP address credit evaluation model of solar eclipse attack defense is considered especially.Finally,the development of block chain technology is prospected from two aspects of technology and supervision.
