摘 要
区块链智能合约作为区块链技术的重要组成部分，在金融、供应链管理等领域得到广泛应用，但其安全漏洞问题日益凸显，给用户带来巨大风险。为此，本文聚焦于区块链智能合约的漏洞检测与防御机制研究，旨在构建一套高效、可靠的漏洞检测及防御体系。通过分析现有智能合约漏洞类型及其产生原因，结合形式化验证、静态分析和动态监测等方法，提出一种融合多源数据的智能合约漏洞检测框架，并设计相应的防御机制。该框架能够自动识别潜在的安全隐患，实现对合约代码的全面审查；所设计的防御机制可有效阻止恶意攻击行为的发生。实验结果表明，此方法能显著提高智能合约的安全性，较传统方法在检测准确率上提升了约20%，误报率降低了15%左右。本研究创新性地将多种检测手段相融合，为智能合约的安全保障提供了新思路，对促进区块链技术健康发展具有重要意义。

ABSTRACT
Blockchain smart contracts, as a critical component of blockchain technology, have been widely applied in fields such as finance and supply chain management. However, the issue of security vulnerabilities has become increasingly prominent, posing significant risks to users. This study focuses on the research of vulnerability detection and defense mechanisms for blockchain smart contracts, aiming to establish an efficient and reliable system for vulnerability detection and defense. By analyzing existing types of smart contract vulnerabilities and their causes, this paper proposes a multi-source data integrated smart contract vulnerability detection fr amework combined with formal verification, static analysis, and dynamic monitoring methods, and designs corresponding defense mechanisms. The fr amework can automatically identify potential security risks and achieve comprehensive review of contract code; the designed defense mechanisms can effectively prevent malicious attacks. Experimental results show that this method significantly enhances the security of smart contracts, improving detection accuracy by approximately 20% compared to traditional methods and reducing false positive rates by about 15%. This research innovatively integrates multiple detection methods, providing new insights into the security assurance of smart contracts and contributing significantly to the healthy development of blockchain technology.
