Ledger Sync EAR99
Ledger Sync is XO Defense's offline transaction state machine with deterministic reconciliation capability. After extended disconnection between two bilateral ledger nodes — hours, days, or weeks — Ledger Sync resolves the distributed state and restores chain consistency without data loss. The protocol handles conflicts that arise when both parties have continued recording transactions independently during disconnection, applying deterministic merge rules that produce the same result regardless of which party initiates reconciliation. Ledger Sync is designed for the reality of DDIL operations: disconnection is the expected state, and reconnection must be seamless.
How XO Defense Addresses This
Ledger Sync completes the Mustard Chain lifecycle: Chain creates the ledger, Seal publishes commitments, and Sync reconciles after disconnection. Together, these three protocols provide complete bilateral ledger capability for environments where continuous connectivity is impossible. Ledger Sync's deterministic reconciliation means both parties converge to the same chain state independently — no arbitration, no conflict resolution server, no human intervention. This is essential for defense operations where supply chain records, payment ledgers, and command logs must remain consistent despite extended communication blackouts.
