CBDC Interoperability Flow

Overview

CBDC interoperability enables cross-sovereign CBDC transfers through the CBDC Interoperability Matrix (CIM), including identity mapping, interledger conversion, and cross-certification.

Prerequisites

Source and destination CBDC systems are registered
CIM service operational
Identity mapping available
Interledger conversion supported

Step-by-Step Process

Step 1: Identity Mapping

Lookup source identity in CIM
Map to destination sovereign identity
Verify cross-certification
Validate KYC/AML standards

Code Reference: src/core/cbdc/interoperability/cim-identity.service.ts

Step 2: Interledger Conversion

Determine conversion rate
Convert amount to target CBDC
Verify conversion parameters
Create conversion record

Code Reference: src/core/cbdc/interoperability/cim-interledger.service.ts

Step 3: Execute Transfer

Post to source ledger (debit)
Post to destination ledger (credit)
Verify both postings
Create interoperability record

Code Reference: src/core/cbdc/interoperability/cim-interledger.service.ts

Error Handling

Identity mapping failure: Return error
Conversion failure: Rollback, return error
Transfer failure: Rollback both ledgers

Integration Points

CIM Identity Service: src/core/cbdc/interoperability/cim-identity.service.ts
CIM Interledger Service: src/core/cbdc/interoperability/cim-interledger.service.ts

Performance Metrics

Total End-to-End: < 200ms target
Throughput: 5,000+ conversions/second
