As Layer 2, like Arbitrum or Base, considers moving towards a more decentralized sequencer model, the platform faces the challenge of maintaining its current mitigation of frontrunning risks inherent in a first come, first served system.
The transition could reintroduce vulnerabilities to transaction ordering manipulation, demanding innovative solutions to uphold transaction fairness. Strategies such as commit-reveal schemes, submarine sends, Fair Sequencing Services (FSS), decentralized MEV mitigation techniques, and the incorporation of time-locks and randomness could play pivotal roles. These measures aim to preserve the integrity of transaction sequencing, ensuring that the L2s evolution towards decentralization enhances its ecosystem without compromising the security and fairness that are crucial for user trust and platform reliability.
