Introduction
A 2021 BIS survey revealed that 86% of global central banks are now exploring Central Bank Digital Currencies (CBDCs), with 14% already piloting programs. While CBDC designs vary globally, their core principles remain consistent: peer-to-peer functionality and cash-like attributes. This article explores the balance between CBDCs' immutable fundamentals and their adaptable implementation paths.
The Consistent Core of CBDCs
Peer-to-Peer & Cash-Like Attributes
CBDCs maintain two essential characteristics:
- Direct liability of central banks (highest credit rating)
- Disintermediation that returns data control to users
Unlike electronic payments, CBDCs:
✅ Eliminate intermediary risks
✅ Preserve user privacy
✅ Don't participate in monetary creation via bank deposits

Adaptive Implementation Frameworks
The CBDC Pyramid Model
BIS's Retail CBDC Technologies paper outlines flexible design dimensions:
| Design Aspect | Options | Digital Yuan Approach |
|---|---|---|
| Architecture | Single/Dual-tier | Hybrid dual-tier |
| Ledger | Centralized/DLT | Modified DLT |
| Access | Account/Token | Account-token hybrid |
| Cross-border | Retail/Wholesale | Multi-currency bridges |
Key Implementation Variations
Operational Architecture
- Single-tier: Direct central bank issuance
- Dual-tier (Digital Yuan model): Combines central bank oversight with commercial bank distribution
Ledger Technology
- Distributed ledgers used selectively for verification
- Transaction processing maintains efficiency
Privacy Features
- Limited anonymity via cryptographic separation
- Traceability for regulatory compliance
Digital Yuan's Innovative Balance
China's approach uniquely:
- Prioritizes security-efficiency equilibrium
- Adapts DLT for verification only
- Implements sub-wallet encryption for privacy
- Prepares for multi-currency CBDC bridges
