SoK: MEV Countermeasures: Theory and Practice. (arXiv:2212.05111v1 [cs.CR])

Blockchains offer strong security guarantees, but they cannot protect the
ordering of transactions. Powerful players, such as miners, sequencers, and
sophisticated bots, can reap significant profits by selectively including,

Miner/Maximal Extractable Value or MEV. MEV bears profound implications for
blockchain security and decentralization. While numerous countermeasures have
been proposed, there is no agreement on the best solution. Moreover, solutions
developed in academic literature differ quite drastically from what is widely
adopted …
