# 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
|
||
|
|
1. Lookup source identity in CIM
|
||
|
|
2. Map to destination sovereign identity
|
||
|
|
3. Verify cross-certification
|
||
|
|
4. Validate KYC/AML standards
|
||
|
|
|
||
|
|
**Code Reference**: `src/core/cbdc/interoperability/cim-identity.service.ts`
|
||
|
|
|
||
|
|
### Step 2: Interledger Conversion
|
||
|
|
1. Determine conversion rate
|
||
|
|
2. Convert amount to target CBDC
|
||
|
|
3. Verify conversion parameters
|
||
|
|
4. Create conversion record
|
||
|
|
|
||
|
|
**Code Reference**: `src/core/cbdc/interoperability/cim-interledger.service.ts`
|
||
|
|
|
||
|
|
### Step 3: Execute Transfer
|
||
|
|
1. Post to source ledger (debit)
|
||
|
|
2. Post to destination ledger (credit)
|
||
|
|
3. Verify both postings
|
||
|
|
4. 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
