论文摘要
以太坊的点对点网络上的用户交易有受到攻击的风险。 Smart Contracts Building Sublows withtralized Finance（DEFI）已向以太坊区块链引入了新的交易订购依赖性。结果，攻击者可以从前后交易中获利。最近，多种减轻交易重新排序操作的方法浮出水面。但是，各个方法在减轻此类攻击及其对整个区块链的影响方面的成功仍然很大程度上没有研究。 在这种知识系统化（SOK）中，我们对最新交易进行分类和分析，重新排序操纵缓解方案。我们没有将我们的分析限制为计划在防止交易重新排序攻击方面的成功，而是评估了其对区块链的全部影响。因此，我们能够完整地了解当前缓解方案的优势和劣势。我们发现目前没有计划完全满足区块链生态系统的所有需求。实际上，所有方法都表明至少一个与区块链生态系统相关的领域的性能不令人满意。
User transactions on Ethereum's peer-to-peer network are at risk of being attacked. The smart contracts building decentralized finance (DeFi) have introduced a new transaction ordering dependency to the Ethereum blockchain. As a result, attackers can profit from front- and back-running transactions. Multiple approaches to mitigate transaction reordering manipulations have surfaced recently. However, the success of individual approaches in mitigating such attacks and their impact on the entire blockchain remains largely unstudied. In this systematization of knowledge (SoK), we categorize and analyze state-of-the-art transaction reordering manipulation mitigation schemes. Instead of restricting our analysis to a scheme's success at preventing transaction reordering attacks, we evaluate its full impact on the blockchain. Therefore, we are able to provide a complete picture of the strengths and weaknesses of current mitigation schemes. We find that currently no scheme fully meets all the demands of the blockchain ecosystem. In fact, all approaches demonstrate unsatisfactory performance in at least one area relevant to the blockchain ecosystem.
