Banking Ledger Design — Double-Entry Bookkeeping, Event Sourcing, and Consistency Down to the Last Cent
How to design the ledger at the heart of a banking system. We cover double-entry principles, the journal and posting data model, balance computation strategies, event sourcing, hot-account concurrency control, idempotenc
