摘 要:
Decentralized Finance(DeFi),即去中心化金融,已引发了金融科技领域的广泛关注. DeFi通过利用区块链技术和智能合约,无需传统中介参与即可提供金融服务.然而,智能合约的潜在漏洞已对DeFi系统稳定性产生了重大影响。基于此,我们采用深度理论研究并通过实际案例研究,结合区块链技术和智能合约的特点,系统性地分析了智能合约漏洞对DeFi系统稳定性的冲击。研究发现,智能合约的漏洞往往导致资金损失,触发市场波动,严重影响了DeFi系统的稳健性。智能合约漏洞类型如重入攻击、时间锁勃列尼次等,不仅使数字资产面临盗窃和欺诈的风险,也助长了市场恐慌,引发了市场价格的剧烈波动。此外,我们还对现有的智能合约审计机制和风险控制措施进行了审查,评估了这些机制与措施在防止和最小化智能合约漏洞的有效性。我们发现,尽管现有的一些审计工具和准则已经在预防和处理智能合约漏洞方面发挥了重要作用,但仍存在一些局限性和挑战。研究结果为DeFi领域的决策者和研究人员提供了宝贵的示范,促使他们更深入了解智能合约的漏洞对DeFi系统稳定性的影响以及审计和风险控制机制的有效性,为进一步研究和改进区块链技术和智能合约提供有价值的参照。

Abstract: 
Decentralized Finance (DeFi) has garnered widespread attention in the fintech sector. By leveraging blockchain technology and smart contracts, DeFi offers financial services without the need for traditional intermediaries. However, the potential vulnerabilities in smart contracts have significantly affected the stability of DeFi systems. Based on this, we conducted in-depth theoretical research and case studies, systematically analyzing the impact of smart contract vulnerabilities on the stability of DeFi systems by combining the characteristics of blockchain technology and smart contracts. The study found that vulnerabilities in smart contracts often lead to financial losses, trigger market volatility, and seriously undermine the robustness of DeFi systems. Types of smart contract vulnerabilities, such as reentrancy attacks and timestamp dependency bugs (note: "时间锁勃列尼次" seems to be a mistranslation or a less-known term; here it's translated as "timestamp dependency bugs" which is a common type of smart contract vulnerability related to time-based conditions), not only expose digital assets to the risks of theft and fraud but also fuel market panic, causing sharp fluctuations in market prices. In addition, we reviewed existing smart contract audit mechanisms and risk control measures, evaluating their effectiveness in preventing and minimizing smart contract vulnerabilities. We found that although some existing audit tools and guidelines have played an important role in preventing and addressing smart contract vulnerabilities, there are still limitations and challenges. The research findings provide valuable insights for decision-makers and researchers in the DeFi field, prompting them to gain a deeper understanding of the impact of smart contract vulnerabilities on the stability of DeFi systems and the effectiveness of audit and risk control mechanisms. This offers a valuable reference for further research and improvement of blockchain technology and smart contracts.
