The rapid evolution of crypto-assets has sparked both enthusiasm and skepticism. While some users see them as revolutionary, others have been disappointed, prompting global institutions like the International Monetary Fund (IMF) and the Financial Stability Board to call for stricter regulations.
Beyond the volatility and speculation, however, the underlying technologies of crypto-assets are advancing swiftly. These innovations hold significant promise for improving financial systems, enhancing security, and supporting public welfare.
This article explores how technologies like tokenization, encryption, and programmability are reshaping payments and financial infrastructure—both in the private and public sectors.
Core Technologies Driving Change
Three key technological advances are contributing to the transformation of digital payments:
Tokenization
Tokenization enables digital representation of assets—such as currencies or securities—on an electronic ledger. This ledger is a synchronized, widely accessible database that is secure, transparent, and easily updated. Importantly, tokenization does not require anonymity, which can undermine financial integrity.
Encryption
Encryption allows compliance checks to be separated from transaction details. Only authorized parties can access sensitive data, increasing both privacy and transparency while maintaining regulatory compliance.
Programmability
Programmability facilitates the creation of self-executing financial agreements, often through "smart contracts." These digital contracts automate processes without relying on a trusted intermediary, reducing cost and delay.
Private Sector Innovation
Armed with these tools, private enterprises are pushing the boundaries of financial services in several key areas:
Tokenization of Financial Assets
Stocks, bonds, and other assets can be tokenized to reduce transaction costs, integrate fractured markets, and broaden access. Tokenization requires a compatible ledger and digital currency—such as regulated stablecoins or tokenized bank deposits.
Automation
Automation enables third-party developers to build programmable features, much like creating apps for smartphones. This opens the door to innovative financial products and personalized services.
While private innovation encourages customization and competition, it may fall short in ensuring security, efficiency, and interoperability across systems. Closed networks could emerge, limiting access and increasing fragmentation.

The Role of Central Banks
Central bank digital currencies (CBDCs) can address many limitations of private systems. They function both as a monetary instrument and as critical infrastructure for clearing and settlement.
As a Monetary Instrument
CBDCs provide a safe, liquid, and universally accessible form of digital money. They reduce counterparty risk and enhance trust in digital payments.
As Financial Infrastructure
CBDCs can serve as a foundational layer that enables interoperability between various private networks—including those for digital assets. A CBDC platform could allow different forms of private money to be exchanged seamlessly, while also supporting smart contracts with a standardized programming language.
Such a system would serve as a public good—a shared resource that makes the entire digital economy more efficient, secure, and inclusive.
Cross-Border Payments
The potential benefits of these technologies extend to international payments, though governance complexities must be addressed.
A public platform could allow licensed financial institutions to trade digital representations of central bank reserves across borders—without requiring major reforms to national payment systems.
Key features include:
- Simultaneous currency exchange to eliminate settlement risk
- Programmable contracts for risk-sharing and liquidity management
- Automated enforcement of capital flow regulations
Moreover, encryption can help balance transparency and privacy. For example, the platform could verify anti-money laundering compliance without exposing individual bidder identities in a foreign exchange auction.
Supporting Public Policy Goals
When implemented thoughtfully, crypto-asset technologies can help achieve vital policy objectives:
- Interoperability between currencies and systems
- Security through centralized reserves, final settlement, and self-executing contracts
- Efficiency gained from lower transaction costs, open participation, and automated processes
These advances can make financial systems more resilient, accessible, and aligned with the public interest.
Frequently Asked Questions
What is tokenization?
Tokenization is the process of converting rights to an asset into a digital token on a secure ledger. These tokens can represent ownership of physical or digital assets and can be traded or programmed.
How do CBDCs differ from stablecoins?
CBDCs are digital currencies issued and backed by a central bank, making them a public form of money. Stablecoins are typically issued by private entities and backed by reserves, but they may carry higher risk depending on their structure and regulation.
Can smart contracts be used in traditional finance?
Yes. Smart contracts can automate agreements such as loans, insurance claims, or trade settlements. They reduce the need for intermediaries and can cut costs and processing time.
Are crypto-asset technologies secure?
When well-designed and properly regulated, systems using encryption and distributed ledgers can enhance security and transparency. However, like all technologies, they must be implemented with strong oversight and governance.
How can these technologies help in cross-border payments?
They can enable instant settlement, reduce currency risk, automate compliance checks, and lower fees. This is particularly beneficial for remittances and international trade.
What are the main challenges ahead?
Key challenges include regulatory harmonization, technical standardization, and ensuring that new systems are inclusive, secure, and resilient to cyber threats.
Conclusion
The real value of crypto-asset technologies may not lie in circumventing authority, but in empowering the public sector to build better financial infrastructure. With upgraded payment systems that incorporate tokenization, encryption, and programmability, we can achieve greater interoperability, security, and efficiency—paving the way for more innovation and better services for all.
