The announcement of Facebook's cryptocurrency Libra on June 18 sparked global reactions, drawing comparisons to Bitcoin. While both are digital currencies, their underlying mechanisms, value propositions, and regulatory frameworks differ significantly. This article explores these distinctions and their implications.
Key Differences Between Libra and Bitcoin
1. Degree of Decentralization
- Bitcoin: A fully decentralized network where transactions are validated through distributed ledger technology (blockchain). Every node maintains complete transaction records, ensuring transparency without central authority.
- Libra: Operates as a "multi-centralized" system governed by the Libra Association (28 members including Visa, eBay, and Uber). Transactions require trust in these entities, making it more centralized than Bitcoin. If 1/3 of members become untrustworthy, the network halts.
Technical Considerations:
Libra optimizes payment efficiency by balancing decentralization with centralized architecture. Its focus on cross-border payments—where speed is less critical—helps mitigate scalability issues inherent in pure blockchain systems.
2. Value Stability
- Bitcoin: No intrinsic value锚定; prices fluctuate based on market speculation and community consensus. Risk of volatility or collapse if trust erodes.
- Libra: Backed by a reserve of fiat currencies (e.g., USD, EUR) and government bonds, providing stability. Unlike Bitcoin, its value derives from tangible assets with sovereign credit backing.
Challenges:
Libra's multi-currency basket complicates exchange-rate management. Shifting demand for different currencies could alter its reserve composition, necessitating active intervention to maintain stability.
3. Regulatory Compliance
- Bitcoin: Lacks centralized oversight, leading to bans in many jurisdictions due to concerns over illicit activities.
- Libra: Registered in Switzerland and subject to U.S. and global financial regulations. However, gaps remain in anti-money laundering (AML) enforcement and cross-border监管协调.
Implications for China:
Libra’s peer-to-peer跨境支付 could challenge capital controls (e.g., $50,000 annual FX limits), potentially triggering capital flight and currency depreciation.
Libra vs. China’s DC/EP
China’s Digital Currency/Electronic Payment (DC/EP) system contrasts with Libra by:
- Leveraging state信用 for发行 stability.
- Prioritizing retail scalability via "long-term演进技术."
- Ensuring privacy through controlled anonymity.
Yet, Libra’s potential dominance in跨境支付 may weaken DC/EP’s global adoption, underscoring the need for proactive policy responses.
FAQs
Q1: Is Libra a cryptocurrency like Bitcoin?
No. Libra is a hybrid model with centralized governance and asset-backed reserves, unlike Bitcoin’s fully decentralized design.
Q2: Can Libra replace national currencies?
Unlikely. It functions as a "cross-sovereign" tool for payments but lacks monetary policy levers held by central banks.
Q3: How might Libra impact the U.S. dollar?
By anchoring to USD assets, Libra could reinforce美元 dominance in global finance.

Q5: Will China adopt Libra?
Unlikely, given its strict capital controls and parallel DC/EP development.
Conclusion
Libra’s innovative yet controverse approach redefines digital货币 paradigms. Its success hinges on navigating regulatory hurdles and maintaining trust—a far cry from Bitcoin’s anarchic roots. For policymakers and investors alike, understanding these nuances is critical to shaping the future of money.
