Deterministic Batching

Deterministic batching is a mechanism used in matching engines where incoming orders are collected over a short, fixed time interval and processed simultaneously rather than sequentially. By grouping orders into a single batch, the exchange removes the incentive for traders to pay for faster network access to front-run others.

All orders within a specific batch are treated as having arrived at the same time, often being matched at a single clearing price. This approach significantly reduces the impact of latency arbitrage and promotes a more level playing field.

It is a critical architectural choice for protocols aiming to prioritize matching fairness over raw execution speed.
