The promise of cryptocurrencies has, for many, fallen short of expectations. What was once hailed as a financial revolution is now often seen as a speculative bubble with limited real-world utility. As a result, global institutions like the International Monetary Fund (IMF) and the Financial Stability Board have called for stronger regulation to address risks related to financial stability, consumer protection, and illicit activities.
Yet while the hype around digital currencies may have cooled, the underlying technologies—such as tokenization, cryptography, and programmability—are advancing rapidly. These innovations hold transformative potential not just for private financial services, but also for public infrastructure. When leveraged responsibly, they can enhance payment systems, improve cross-border transactions, and ultimately serve broader societal goals.
This article explores how core blockchain-derived technologies are reshaping finance, why public sector involvement is essential, and how central bank digital currencies (CBDCs) could unlock a more secure, efficient, and inclusive financial future.
The Technological Leap Behind Digital Finance
Three foundational technologies are driving the next wave of innovation in digital finance: tokenization, cryptography, and programmability.
Tokenization: Digitizing Ownership with Integrity
Tokenization refers to representing assets—like money, stocks, or bonds—as digital tokens on a shared electronic ledger. This ledger is distributed across multiple participants, ensuring it's tamper-resistant, synchronized, and highly accessible. Unlike some early blockchain applications that prioritized anonymity, modern systems prioritize compliance and auditability. Complete anonymity is neither necessary nor desirable in regulated financial systems, where transparency supports financial integrity.
By converting traditional assets into digital tokens, we can streamline settlement, reduce counterparty risk, and enable 24/7 market operations.

Cryptography: Securing Trust Without Sacrificing Privacy
Cryptography enables selective data access—ensuring only authorized parties can view sensitive information while still allowing transparent verification of transactions. This separation of compliance checks from transaction execution builds trust without compromising privacy. For example, a platform can verify that a user meets anti-money laundering (AML) requirements without revealing their identity during bidding in a foreign exchange market.
This balance between privacy and regulatory oversight is critical for building scalable and trustworthy digital financial ecosystems.
Programmability: Automating Finance with Smart Contracts
Programmability allows financial agreements to be coded into self-executing "smart contracts." These contracts automatically trigger actions when predefined conditions are met—eliminating the need for intermediaries and reducing delays and errors.
Imagine a contract that releases payment only after delivery confirmation, or one that uses real-time data to settle insurance claims instantly. Such automation increases efficiency and opens doors to entirely new financial products and services.
Private Sector Innovation: Progress with Limitations
The private sector has been at the forefront of applying these technologies. From tokenized securities to stablecoins and automated DeFi protocols, innovation is accelerating.
- Tokenized financial assets—such as stocks and bonds—can lower transaction costs, unify fragmented markets, and expand access to capital.
- Stablecoins, when properly regulated, offer fast and low-cost payment solutions.
- Tokenized bank deposits are being tested by financial institutions, bridging traditional banking with digital infrastructure.
- Automation platforms allow third-party developers to build financial applications—similar to how app stores transformed mobile computing.
However, private innovation alone cannot guarantee system-wide benefits. Even under effective regulation, privately operated networks risk becoming closed ecosystems—accessible only to select users or institutions. While open ledgers may emerge to connect these silos, the lack of strong profit incentives could lead to underinvestment and poor standardization.
Moreover, settling transactions using private forms of money introduces counterparty risk. If a stablecoin issuer fails or a platform collapses, users could face significant losses.
The Critical Role of Central Bank Digital Currencies (CBDCs)
Central bank digital currencies (CBDCs) represent a unique opportunity to combine the strengths of public and private innovation. CBDCs are not just a new form of money—they are also foundational infrastructure for the digital economy.
While much policy debate focuses on CBDCs as a store of value or medium of exchange, their role as settlement infrastructure deserves equal attention.
As infrastructure, CBDCs can:
- Enable interoperability between different private payment systems.
- Provide secure settlement finality.
- Support programmable transactions through standardized smart contract environments.
- Reduce liquidity costs by enabling real-time collateral use.
For example, a CBDC platform could allow payments from one private digital currency to another. Funds could be held in escrow and released only when specific conditions are met—such as the receipt of a tokenized asset. This creates trustless, automated settlements that minimize risk and maximize efficiency.

Furthermore, CBDCs can serve as a public good—a neutral, reliable backbone for the digital financial system that ensures fairness, security, and broad access.
Transforming Cross-Border Payments
One of the most promising applications of this technology lies in cross-border payments—a domain long plagued by high costs, slow processing times, and complex intermediation.
A public multi-currency platform could allow regulated institutions to trade digital representations of domestic central bank reserves across borders. Participants wouldn’t need direct access to each other’s national payment systems or full regulatory oversight from foreign authorities.
Such a system would integrate:
- Simultaneous currency exchange via atomic swaps—eliminating settlement risk.
- Automated risk-sharing contracts to stabilize volatile or illiquid currency pairs.
- Programmable compliance to enforce capital controls where needed.
- Liquidity optimization, allowing future receivables to be used as collateral today.
Crucially, all contracts would be fully backed by escrowed funds, automatically executed, and interoperable with other systems—minimizing default risk and operational friction.
Cryptography ensures compliance with AML/KYC rules while preserving operational privacy. For instance, users could place anonymous bids in foreign exchange markets while still seeing aggregate bid-ask spreads—balancing transparency with confidentiality.
Key Public Policy Benefits
When thoughtfully implemented, these technologies support three core public policy objectives:
- Interoperability between national currencies and financial systems.
- Security through central bank-backed settlement, finality, and automated enforcement.
- Efficiency via low transaction costs, open participation, standardized contracts, and high transparency.
These outcomes aren't theoretical—they’re being tested in pilot programs worldwide and supported by research from leading institutions like the IMF and the Bank for International Settlements (BIS).
