论文摘要
以太坊中的分散财务（DEFI）是一个金融生态系统，建立在锁定超过2000亿美元的区块链上，直到2022年4月。所有交易信息都是透明的，并且在通过DEFI协议进行交易时，这导致了一系列攻击。几项研究试图从经济和技术角度优化它。但是，很少有作品可以分析整个Fefi系统的漏洞和优化。在本文中，我们首先系统地分析了以太坊在多个层面上与Defi相关的漏洞，然后研究现实世界的攻击。最后，我们总结了DEFI优化的成就，并提供了一些未来的方向。
Decentralized finance (DeFi) in Ethereum is a financial ecosystem built on the blockchain that has locked over 200 billion USD until April 2022. All transaction information is transparent and open when transacting through the DeFi protocol, which has led to a series of attacks. Several studies have attempted to optimize it from both economic and technical perspectives. However, few works analyze the vulnerabilities and optimizations of the entire DeFi system. In this paper, we first systematically analyze vulnerabilities related to DeFi in Ethereum at several levels, then we investigate real-world attacks. Finally, we summarize the achievements of DeFi optimization and provide some future directions.
