Central Bank Digital Currencies (CBDCs) are emerging as a transformative force in the global financial landscape. As nations explore digitizing their monetary systems, fundamental questions arise about the future of cash, the role of blockchain, and the broader economic implications of this shift.
In a recent dialogue on blockchain’s potential, Nobel laureate Eric Maskin and Chen Long, Secretary of the Luohan Academy, explored how digital currencies and distributed ledger technology could reshape markets, reduce information asymmetry, and redefine trust in economic transactions.
Understanding the Shift from Traditional to Digital Money
Money has been evolving for centuries—from commodity money and coins to paper currency and digital payment systems. Today, that evolution is accelerating toward state-backed digital currencies.
CBDCs represent a digital form of a country’s fiat currency, issued and regulated by the central bank. Unlike decentralized cryptocurrencies such as Bitcoin, a CBDC is centralized and enjoys government backing, making it a reliable and stable medium of exchange.
Many societies are already transitioning toward cashless systems. But CBDCs go beyond mere digitization—they are programmable, traceable, and capable of embedding contractual and regulatory conditions within the currency itself.
Why Bitcoin Won’t Replace Sovereign Currency
Despite the popularity of cryptocurrencies, they are unlikely to replace state-issued money. Bitcoin and similar assets operate without government endorsement or institutional trust. This lack of formal backing limits their usefulness for everyday transactions and broader economic integration.
Cryptocurrencies can also pose risks to financial stability. Their high volatility, scalability issues, and energy-intensive mining processes make them impractical as primary currencies. Moreover, they could undermine the effectiveness of monetary policy if widely adopted.
As Maskin argues, private cryptocurrencies may eventually fade from prominence, whereas CBDCs—supported by national credibility—are positioned to become the next evolutionary step in money.

The Role of CBDCs in Cross-Border Payments
One of the most promising applications of CBDCs is in improving cross-border payments. Traditional international transfers are often slow, expensive, and reliant on intermediaries. Transaction fees can be prohibitively high, especially for migrant workers sending remittances home.
CBDCs can streamline these processes by enabling near-instant settlements, reducing costs, and enhancing transparency. By digitizing trust and verification, central bank digital currencies could make financial systems more accessible and efficient for users worldwide.
How Blockchain Enhances Trust and Reduces Information Gaps
Blockchain, the technology underpinning many digital currencies, offers more than just cryptocurrency—it provides a new model for trust.
In traditional transactions, parties often need to establish trust through collateral, reputation, or third-party verification. Blockchain reduces this dependency by enabling cryptographic proof and decentralized consensus. This allows strangers to transact securely without prior trust.
This capability has profound implications for lending, contracting, and organizational design. By lowering transaction costs and mitigating information asymmetry, blockchain can broaden participation in economic systems—especially for underserved individuals and small businesses.
Smart Contracts and the Future of Organizations
Smart contracts—self-executing agreements coded on a blockchain—can automate and enforce contractual terms without intermediaries. This raises intriguing questions about the future of firms and outsourcing.
If contracts can be executed seamlessly, will companies still need internal departments for HR, legal, or quality control? While some functions may become more outsourced, others—like brand management and quality assurance—are difficult to fully encode in a contract.
Firms may persist because they provide intangible value: reputation, culture, and accountability that are not easily captured in algorithms.
Blockchain as a Tool for Reducing Inequality
Information asymmetry isn’t just inefficient—it can reinforce inequality. Those without collateral or credit history often struggle to access loans and other financial services.
Blockchain can help overcome these barriers. By using data (rather than physical assets) as collateral, lenders can assess creditworthiness more accurately. This allows entrepreneurs from less privileged backgrounds to secure funding based on their potential rather than their past.
In this way, blockchain and CBDCs could contribute to a more inclusive economic system.
Frequently Asked Questions
What is a Central Bank Digital Currency (CBDC)?
A CBDC is a digital form of sovereign currency issued and backed by a central bank. It aims to combine the efficiency of digital transactions with the stability of traditional fiat money.
How is a CBDC different from Bitcoin?
Unlike Bitcoin, which is decentralized and unbacked by any government, a CBDC is centralized, regulated, and issued by a monetary authority. This makes it more stable and integrated with national economic policies.
Can CBDCs improve financial inclusion?
Yes. By reducing transaction costs and enabling digital identities, CBDCs can provide banking services to unbanked and underbanked populations.
Will digital currencies replace cash completely?
While many societies are moving toward cashless systems, the complete replacement of cash will depend on technological access, regulatory frameworks, and public acceptance.
Are smart contracts legally binding?
This varies by jurisdiction. While smart contracts automate execution, their legal status is still evolving. Many countries are adapting laws to recognize blockchain-based agreements.
How do CBDCs affect privacy?
CBDCs can be designed with varying levels of privacy. Some models allow anonymous transactions like cash, while others offer traceability for regulatory purposes.
Conclusion
The global transition toward digital currencies is underway. While the demise of cash may not be immediate, the functional advantages of CBDCs—such as efficiency, transparency, and programmability—suggest they will play a central role in future monetary systems.
As Eric Maskin predicts, within two decades, we may live in a world where physical money is largely obsolete. Whether through CBDCs or enhanced blockchain systems, the fusion of technology and trust is set to redefine what money is—and how it works.
