Settlement Assurance Model
Complete transaction lifecycle from intent submission through deterministic finality. Every settlement passes through four defined stages, each with specific validation gates and integrity checks.
Transaction Lifecycle
Every JIL settlement follows a deterministic 4-stage lifecycle. Each stage has defined entry criteria, validation gates, and exit conditions. No stage can be skipped or reordered.
Settlement Finality
JIL provides deterministic finality - not probabilistic. When a settlement reaches Stage 4, it is final. There is no confirmation window, no chain reorganization risk, and no rollback possibility.
What Deterministic Finality Means
- Settlement is complete when 14-of-20 validators attest - there is no "waiting for confirmations"
- Once finalized, the settlement cannot be reversed, reorganized, or invalidated
- Finality is cryptographically provable via the settlement receipt
- Receipt contains validator signatures, timestamp, policy hash, and beneficiary binding
Comparison to Probabilistic Systems
| Property | JIL (Deterministic) | Bitcoin/Ethereum (Probabilistic) |
|---|---|---|
| Finality | Immediate on attestation | 6+ confirmations (Bitcoin), 12+ blocks (Ethereum) |
| Reorganization risk | None | Possible until sufficient depth |
| Time to finality | Sub-second | 60+ minutes (Bitcoin), 6+ minutes (Ethereum) |
| Receipt | Cryptographic, validator-signed | Block inclusion (no institutional receipt) |
Deterministic Settlement Properties
The settlement protocol enforces several properties that distinguish it from general-purpose blockchains.
- Order independence: Settlement outcome is the same regardless of transaction ordering within a block
- Idempotency: Resubmitting the same settlement intent produces the same result - no double-settlement risk
- Atomicity: A settlement either completes fully or not at all - no partial states
- Auditability: Every stage transition is logged with timestamps, validator IDs, and policy evaluations
- Non-repudiation: The finality receipt provides cryptographic proof that both parties authorized the settlement
Validator Responsibility Model
Each validator in the 14-of-20 consensus operates under defined responsibilities. Validators are not anonymous miners - they are identified nodes operating under compliance agreements.
| Responsibility | Description | Enforcement |
|---|---|---|
| Settlement attestation | Validate and sign settlement proposals | Consensus protocol |
| Policy enforcement | Verify corridor policies match settlement parameters | Policy engine |
| Uptime commitment | Maintain availability for consensus participation | SentinelAI monitoring |
| Key security | Protect validator signing keys from compromise | HSM + AES-256-GCM |
| Jurisdictional compliance | Operate within assigned compliance zone | 7-gate bootstrap |
Integrity Guarantees
The settlement assurance model provides the following integrity guarantees to institutional counterparties.
- No unauthorized settlement: Requires MPC 2-of-3 authorization from the user - the platform cannot settle without user participation
- No policy bypass: Every settlement is validated against the active policy corridor before consensus
- No silent failure: Failed settlements produce explicit error receipts with failure reasons
- No data leakage: Settlement data is partitioned by jurisdiction - validators only process data for their assigned zones
- No retroactive modification: Finalized settlements are immutable - the ledger does not support state rollback
Monitoring and Observability
Settlement assurance is continuously monitored across the validator fleet.
- SentinelAI Fleet Inspector: Automated health monitoring with threat scoring and auto-recovery
- Real-time telemetry: Settlement latency, throughput, and error rates tracked per validator
- Consensus health: Quorum participation monitored - adaptive threshold adjusts if validators go offline
- Heartbeat monitoring: Every validator sends periodic heartbeats - missed heartbeats trigger investigation
