## Order Matching Engine Integrity

Order matching engine integrity involves the technical and logical safeguards that ensure a trading venue correctly pairs buy and sell orders based on price and time priority. This core component of an exchange must be resilient against front-running, latency manipulation, and order book poisoning.

Integrity is maintained through deterministic execution logic and high-speed, auditable logging of every state change within the system. If the matching engine is compromised, it could lead to incorrect pricing, unfair execution, or the creation of phantom liquidity.

Security protocols here focus on preventing unauthorized code injection and ensuring that all participants interact with the market under identical rules. Protecting this engine is vital for maintaining market trust and regulatory compliance.
