A Blockchain Security Architecture Based on Web Attack Principles

In recent years, blockchain technology, as an innovative information technology, has received widespread attention in academia and industry. However, its limitations in mechanism design and the completeness of supporting infrastructure, combined with the immaturity of security concepts, have exposed blockchain systems to severe security threats and challenges. This study aims to address critical security issues in blockchain technology by proposing a blockchain security architecture based on Web attack principles. The architecture adopts a negotiated consensus mechanism and integrates real-time protection techniques from the field of cybersecurity, designing an innovative framework capable of identifying and restricting malicious nodes. With dynamic isolation as its core strategy, the architecture detects abnormal behaviors and temporarily isolates malicious nodes, preventing further damage to the blockchain network. The results demonstrate that this architecture successfully addresses the bottlenecks of inadequate targeted defense in existing blockchain systems and significantly improves operational efficiency and security. Experimental validation indicates that the architecture exhibits substantial practical value in scenarios such as decentralized finance (DeFi) and supply chain management, laying a solid foundation for the widespread application of blockchain technology in real-world settings.
