Matching Engine Architecture Meaning

The technical blueprint of how an exchange's core logic is built and deployed. Modern architecture focuses on vertical scaling and memory-centric design.

Because speed is the ultimate competitive advantage, matching engines are often written in low-level languages like C++ or Rust and keep the entire order book in RAM to avoid the delay of reading from a hard drive. A robust architecture also prioritizes determinism.

This means that if you fed the same sequence of orders into the engine twice, the result would be identical. This is critical for auditing and reconciliation.

If the engine's logic is inconsistent, it could lead to ghost orders or double spending, which would destroy the exchange's reputation.
