The 2008 global financial crisis exposed the inherent contradictions of the U.S. dollar-dominated international monetary system, raising doubts about its stability and sustainability. Against this backdrop, a Japanese-American individual using the pseudonym "Satoshi Nakamoto" proposed the concept of a decentralized cryptocurrency system in 2008. This cryptocurrency's transactions and account information would be stored across numerous network nodes, where modifications to one or multiple nodes wouldn't alter existing transaction records—thus giving birth to blockchain technology. Bitcoin emerged as this blockchain-powered cryptocurrency, later gaining popularity among speculative investors.
The Rapid Evolution of Digital Currencies
Since Bitcoin's debut in 2009, the explosive growth of digital currencies has captured global attention. Researcher Zhang Ming's team from the Chinese Academy of Social Sciences Financial Research Institute has conducted long-term tracking and research on digital currency development, recently publishing their latest work The Boundaries of Digital Currency: Disruption or Gradual Transformation? through Oriental Press. This book compiles a decade of research findings, systematically categorizing and comparing various digital currencies while offering profound insights into their future evolution from the perspective of international monetary system reform.
Three Categories of Digital Currency
Following major global shocks—including the 2008 financial crisis, 2020 pandemic, and 2022 Russia-Ukraine conflict—flaws in the current international monetary system have drawn scrutiny, with growing calls for reform. Digital currencies present new possibilities for such reform. To date, digital currencies fall into three main categories:
- Cryptocurrencies like Bitcoin
- Stablecoins such as Libra (now Diem)
- Central bank digital currencies (CBDCs) exemplified by China's e-CNY
Bitcoin's Advantages and Limitations
Zhang Ming observes that while Bitcoin features decentralization and traceable transactions, its fixed supply potentially leads to economic deflation. Moreover, Bitcoin's independence from existing monetary systems leaves it without a value foundation, hindering its function as true currency.
The Stablecoin Dilemma
Stablecoins operate on consortium blockchains with partial decentralization, deriving value from underlying asset pools comprising various currencies and financial instruments. However, their private currency nature, cross-border regulatory complexity, and significant impact on existing monetary systems have drawn strong regulatory opposition.
The Rise of CBDCs
Central bank digital currencies like China's digital yuan don't fully rely on blockchain technology, maintaining higher centralization. Their value stems from sovereign credit, essentially representing digitized forms of sovereign currencies.
Digital Currencies' Role in Monetary System Reform
Zhang Ming contends that international monetary system evolution occurs gradually. Currently, digital currencies cannot fundamentally overturn existing systems through legal channels nor solve issues like international payment imbalances and financial risk contagion through technological superiority alone. Their optimal role lies not in seeking disruptive alternatives but serving as technical extensions of major sovereign currencies—reducing transaction costs and expanding payment models to gradually decrease reliance on current systems.
China's early adoption of digital yuan pilot programs positions it advantageously in the global CBDC competition. However, a currency's internationalization ultimately depends on:
- The issuing country's economic scale and development level
- Depth, breadth, and liquidity of its financial market products
- The nation's crisis adjustment capacity
Both digital yuan's development and its internationalization journey remain lengthy processes.

Q: What makes Bitcoin different from traditional currencies?
A: Bitcoin operates independently of central banks, uses blockchain technology for verification, and has a capped supply—features absent in fiat currencies.
Q: Why are stablecoins controversial?
A: Their private issuance challenges monetary sovereignty, while cross-border flows complicate regulation, potentially destabilizing national economies.
Q: How might CBDCs impact everyday transactions?
A: CBDCs could enable faster, cheaper payments with enhanced traceability while maintaining sovereign currency stability—👉 Learn more about digital payment innovations.
Q: What advantages does China's digital yuan offer?
A: Early adoption provides first-mover benefits in technology standards and cross-border applications, though full implementation requires addressing scalability and international acceptance challenges.
Q: Can cryptocurrencies replace traditional money?
A: Unlikely in the near term due to volatility, regulatory hurdles, and lack of universal acceptance—though they may complement existing systems.
Q: How does blockchain ensure transaction security?
