The foundational mathematical accounting system powering world-class banks. For every debit from account A, an exact equal credit must post to account B.
Single-entry ledgers are prone to rounding drift and phantom currency creation. Double-entry bookkeeping guarantees that the sum of all debits equals the sum of all credits across the entire institution at every single millisecond of execution.
Debits always equal credits: Sum(Debits) - Sum(Credits) = 0 across the entire bank.
Atomic, Consistent, Isolated, and Durable database operations prevent data corruption.
Transactions cannot be deleted—only offsetting adjustments can be recorded.
Database record locks prevent concurrent transfer collisions.
| Ledger Invariant | Total System Assets == Total System Liabilities + Equity |
| Database Engine | Atomic state machine with ACID transactional guarantees |
| Audit Format | ISO-8601 timestamps + cryptographic NXB hashes |
