Offchain Labs, the development team behind Arbitrum, proposed a modified transaction ordering strategy proposal for the Arbitrum sequencer, adding a "time boost" to the current "first come, first served" strategy, where transactions can pay a priority fee to get a A small advantage or a "time boost" advantage in sorting. Offchain Labs said that this should not affect most users, but it can provide a better way to manage latency racing behavior. Arbitrum sequencers receive transactions from users and issue an ordered sequence as input to the Arbitrum execution phase. Currently, the sorter follows a first-come-first-served (FCFS) sorting strategy.
