SoK: Preventing Transaction Reordering Manipulations in Decentralized Finance. (arXiv:2203.11520v1 [cs.CR])

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 …
