## Sequence Number Tracking

Sequence Number Tracking is a mechanism used to maintain the order of events in a distributed system, ensuring that messages are processed in the sequence they were intended. In financial derivatives trading, where the timing and order of orders are critical for price discovery, sequence numbers prevent out-of-order execution.

Each message is tagged with a sequence number, and the receiver verifies that they are processed in the correct order. If a message arrives out of sequence, the system can buffer it or request a retransmission.

This is essential for maintaining the state consistency of an order book across different nodes. It protects against various network-level attacks that might attempt to reorder or delay specific trade messages to gain an unfair advantage.

By enforcing strict sequencing, platforms ensure that the market microstructure remains fair and transparent for all participants, regardless of network latency or packet delivery variations.
