A matching engine for high-frequency trading requires deterministic state-machine replication and single-threaded logic to handle high throughput with strict latency. This Skill provides a framework covering price-time priority and fault tolerance across multiple nodes.

State machine replication in a matching engine ensures determinism under replication, guaranteeing fault tolerance and state consistency across multiple nodes. It enables the system to process identical inputs sequentially and maintain synchronized order books.

A matching engine distributes market data using UDP multicast for efficient, low-latency dissemination to subscribers. This approach handles high throughput by broadcasting order book updates without establishing individual network connections.

Circuit breakers protect a stock exchange matching engine by halting trading to mitigate system instability. They are implemented at order, symbol, and market levels to prevent cascading failures during extreme volatility.

Yes, this matching engine design works for crypto exchanges. The framework is suitable for both equities and crypto exchanges, addressing high throughput requirements, deterministic matching, and strict latency constraints.

Deterministic order matching across replicated nodes is ensured by using single-threaded logic and state-machine replication. This guarantees that all nodes process identical sequences of orders to maintain state consistency.
