F3B: A Low-Latency Commit-and-Reveal Architecture to Mitigate Blockchain Front-Running. (arXiv:2205.08529v1 [cs.CR])

Front-running attacks, which benefit from advanced knowledge of pending
transactions, have proliferated in the cryptocurrency space since the emergence
of decentralized finance. Front-running causes devastating losses to honest
participants$\unicode{x2013}$estimated at \$280M each month$\unicode{x2013}$and
endangers the fairness of the ecosystem. We present Flash Freezing Flash Boys
(F3B), a blockchain architecture to address front-running attacks by relying on
a commit-and-reveal scheme where the contents of transactions are encrypted and
later revealed by a decentralized secret-management committee once the
underlying consensus layer has …
