This constitutes a major flaw discovered with the introduction of decentralized finance and allows miners to perform MEV attacks. In this paper, we address the issue of sandwich attacks by providing a construction that takes as input a blockchain protocol and outputs a new blockchain protocol with the same security but in which sandwich attacks are not profitable. Furthermore, our protocol is fully decentralized with no trusted third parties or heavy cryptography primitives and carries a linear increase in latency and minimum computation overhead."}],"intvolume":"       286","volume":286,"year":"2024","file_date_updated":"2024-02-26T10:16:57Z","acknowledgement":"We would like to thank Krzysztof Pietrzak and Jovana Mićić for useful discussions.
