Adversarial Sequencer Behavior

Mechanism

Adversarial sequencer behavior describes the strategic manipulation of transaction ordering by block producers to extract economic value at the expense of network participants. By reordering, inserting, or censoring specific transactions within a block, sequencers optimize their own financial outcomes through frontrunning or sandwich attacks. This activity directly impacts market microstructure, as the latency between submission and inclusion allows for the exploitation of price discovery discrepancies. Such practices undermine the neutrality of decentralized exchanges and create hidden costs for liquidity providers.
