Order Collisions

Order collisions occur when multiple orders attempt to access the same liquidity or matching engine slot simultaneously, creating contention within the protocol. In a decentralized environment, this often results in failed transactions or increased gas costs as participants compete to be included in the next block.

Managing these collisions is a critical task for sequencers and consensus mechanisms, which must decide which orders are processed first. Frequent collisions can indicate a highly competitive or congested market, often leading to poor user experience.

Effective protocols use sophisticated queuing or prioritization strategies to resolve these collisions without compromising fairness.
