Sub-Volume A: Global Atomic Settlements (GAS) Network

Overview

The Global Atomic Settlements (GAS) Network enables instant, irreversible, atomic settlement across multiple financial dimensions:

• Classical financial networks
• CBDC chains
• Commodity token networks
• Security token systems
• Quantum financial rails
• Multiversal DBIS layers

Architecture

Multi-Dimensional Atomic Settlement

GAS extends the existing atomic settlement service to support multi-dimensional commit verification:

atomic_settlement = HASH(
   scb_commit,
   dbis_commit,
   fx_commit,
   asset_commit,
   temporal_state
)

Settlement is only final when all commits match across dimensions.

Smart Routing

GAS uses a hybrid routing approach combining:

• SIRE (Sovereign Interoperability Routing Engine) - Cost and risk optimization
• CASO (Cross-Border Algorithmic Settlement Optimizer) - Cross-border route optimization
• ARIFX (Future module) - Advanced routing for interplanetary and multiversal transactions

Routing optimization considers:

• Cost (FX, liquidity, risk)
• Latency (settlement time)
• Dimensional alignment (cross-reality consistency)

Services

GasSettlementService

Main service for executing GAS atomic settlements.

Location: src/core/settlement/gas/gas-settlement.service.ts

Key Methods:

• executeGasSettlement() - Execute multi-dimensional atomic settlement
• getGasSettlement() - Get settlement by ID
• getGasSettlementsForBank() - Get settlements for a bank
• isSettlementAtomicAndVerified() - Verify settlement is atomic and all commits matched

GasCommitmentService

Service for creating and verifying multi-dimensional commitments.

Location: src/core/settlement/gas/gas-commitment.service.ts

Key Methods:

• createMultiDimensionalCommitment() - Create commits across all dimensions
• verifyAllCommitsMatch() - Verify all commits match
• getCommitment() - Get commitment by settlement ID

GasRoutingService

Service for smart routing using SIRE + CASO + ARIFX.

Location: src/core/settlement/gas/gas-routing.service.ts

Key Methods:

• calculateOptimalRoute() - Calculate optimal route using hybrid routing
• getRoutingHistory() - Get routing history

API Endpoints

Settlement

• POST /api/gas/settle - Execute GAS atomic settlement
• GET /api/gas/settlement/:gasSettlementId - Get settlement by ID
• GET /api/gas/settlements/bank/:sovereignBankId - Get settlements for a bank
• GET /api/gas/settlements/network/:networkType - Get settlements by network type

Routing

• POST /api/gas/route - Calculate optimal route
• GET /api/gas/routing/history - Get routing history

Commitment

• GET /api/gas/commitment/:settlementId - Get commitment by settlement ID
• POST /api/gas/commitment/verify - Verify all commits match

Database Schema

GasSettlement

Main settlement record for GAS transactions.

Fields:

• gasSettlementId - Unique GAS settlement identifier
• settlementId - Reference to AtomicSettlement
• networkType - Network type (classical, cbdc, commodity, security, quantum, multiversal)
• commitmentHash - Hash of all commitments
• dimensionalAlignment - Dimensional alignment score
• allCommitsMatched - Whether all commits matched

GasCommitment

Multi-dimensional commitment record.

Fields:

• scbCommit - SCB ledger commit hash
• dbisCommit - DBIS master ledger commit hash
• fxCommit - FX commit hash (optional)
• assetCommit - Asset commit hash (optional)
• temporalState - Temporal state commit (optional)
• commitmentHash - Combined hash of all commits

GasRoutingDecision

Routing decision record.

Fields:

• routingEngine - Engine used (sire, caso, arifx, hybrid)
• optimalRoute - Calculated optimal route
• cost - Total route cost
• latency - Estimated latency in milliseconds
• dimensionalAlignment - Dimensional alignment score

Integration Points

• Atomic Settlement Service: Extends src/core/settlement/isn/atomic-settlement.service.ts
• SIRE: Integrates with src/core/settlement/sire/sire-routing.service.ts
• CASO: Integrates with src/core/settlement/caso/caso-routing.service.ts
• ARIFX: Placeholder for future module

Use Cases

Real-Time Interbank Transactions

Instant settlement between sovereign central banks using classical financial networks.

Interplanetary CBDC Settlement

Settlement across planetary systems (Earth, Luna, Mars) with temporal state tracking.

Multi-Asset Instantaneous Swaps

Atomic swaps across multiple asset types (currency, CBDC, commodity, security).

Synthetic Derivative Execution

Instant execution of synthetic derivatives with multi-dimensional commit verification.

Example Usage

import { gasSettlementService } from '@/core/settlement/gas/gas-settlement.service';

// Execute GAS settlement
const result = await gasSettlementService.executeGasSettlement({
  sourceBankId: 'OMNL',
  destinationBankId: 'USCB',
  amount: 1000000,
  currencyCode: 'USD',
  assetType: 'currency',
  networkType: 'classical',
  optimizeFor: 'cost',
});

console.log(`Settlement ID: ${result.gasSettlementId}`);
console.log(`All commits matched: ${result.allCommitsMatched}`);

Status

✅ Implemented - Sub-Volume A is fully implemented and integrated with existing DBIS systems.
