## Event Driven Architecture

Event Driven Architecture in the context of financial derivatives and cryptocurrency is a software design pattern where the flow of the system is determined by events such as trade executions, price updates, or order book changes. Instead of a system polling for data, components react asynchronously to state changes published by a central event bus.

This architecture is crucial for high frequency trading platforms and decentralized exchanges because it minimizes latency and allows for massive scalability. When a trade occurs, an event is emitted, triggering downstream processes like risk management checks, margin updates, and ledger settlement.

By decoupling producers of data from consumers, the system remains highly responsive under volatile market conditions. It enables real-time processing of complex order flows, ensuring that participants receive updated information instantly.

This approach is fundamental to building robust infrastructure that can handle the rapid throughput requirements of modern digital asset markets.
