Most payment systems were built on the request-response model. This model collapses when operations need to transit between multiple rails with different response times.
Events as Source of Truth
In Infracash's architecture, each state transition generates an immutable event. Any operation's state can be reconstructed from its event sequence. The advantage is threefold: auditability, resilience, and extensibility.
CQRS and Automatic Reconciliation
The separation between commands and queries is natural in event-driven architecture. Reconciliation is continuous and real-time.
