The rise of blockchain technology is sending rippling effects across the payments landscape. From central bank digital currencies (CBDCs) to AI-enhanced fintech security solutions and more, the applications are expanding quickly. Protecting sensitive payment information, especially cardholder data and credit card data, is becoming increasingly important in this evolving landscape.
While some solutions are further off, one innovation is happening today: the tokenization of real-world assets (RWA).
Tokenization uses digital representations — also known as “tokens” — of hard assets, such as money, real estate, art or even contractual obligations. It embeds them into data that moves between parties through a blockchain. This process is crucial for securing payment card data against unauthorized access, ensuring that sensitive information is kept safe from potential breaches.
According to a recent report from McKinsey & Company, the market for these kinds of tokenized digital deals is projected to reach $5 trillion by 2030.
How tokenization works
By converting the rights to an asset into digital tokens, international businesses can ensure transparency, security, and immutability backed up by a secure blockchain while significantly enhancing data protection and data security.
The tokens represent ownership or fractional ownership of the underlying RWA, which can range from investments to intellectual property. This method is particularly effective in credit card tokenization, where sensitive credit card information is protected by replacing it with non-sensitive equivalents, or tokens, safeguarding the original card information from fraud during online transactions.
Imagine a real estate investor acquiring a stake in a property through tokenization. That equity would be transferred in exchange for cash over a blockchain. Instead of this transaction being processed by a traditional wire or ACH transfer, the blockchain will include an impenetrable token with legally binding items attached, offering a robust layer of data security and data protection.
The process produces numerous benefits, such as increased liquidity, fractional ownership, and streamlined trading, all while ensuring the highest standards of data protection and security.
Enhancements in tokenization are also expected to increase access for investors from all backgrounds, opening up asset classes that have historically been restricted to institutions, funds, and high-net-worth individuals.
Real world asset tokenization’s use cases
According to Ripple’s 2023 New Value Report, half of global finance leaders believe tokenization will significantly affect all asset classes, from real estate to derivatives and carbon credit markets. Unlike encrypted data, which relies on reversible encryption and a secret decryption key, tokenization offers a unique security benefit by replacing sensitive information with a non-sensitive equivalent, known as a token, that has no extrinsic or exploitable meaning or value.
Additionally, tokenization of RWA include protecting sensitive cardholder data in financial transactions. This happens by replacing it with tokens to enhance data protection and comply with industry standards and government regulations. Other use cases include:
Stocks and bonds
Tokenization streamlines the trading of stocks and bonds by exchanging ownership rights through digital tokens — without the need for a broker-dealer or formal clearinghouse. This enables trading around the clock at a reduced cost to buyers and sellers.
Collectibles
For everything from historic paintings to rare baseball cards, tokenization facilitates the fractional ownership of collectibles, allowing enthusiasts to invest in high-value pieces. This broadens the art and collectibles market and prevents fraud, while transparently delivering appraisal and storage information.
Commodities
With much interest in the cross-border trading of commodities such as oil and rare minerals, tokenizing such RWA provides investors with exposure to these assets without the need for physical ownership or any of the overhead that comes with it. This encourages diversification and brings more liquidity into the market.
Intellectual property
Tokenization gives inventors, artists, programmers and musicians new ways to monetize their creations. Patents, copyrights and royalties can be embedded in the blockchain to essentially make a new market for investors who want to buy or sell pieces of the IP or passively collect revenue from it.
Regulatory technology in a tokenized economy
As blockchain technology paves the way for an ever-expanding suite of fintech solutions, particularly in sectors that rely on cross-border payments, there is a growing need for standardization and compliance in the payment card industry. With different currencies, cultures and sets of rules governing so many RWA on a global scale, the trading of these assets can be daunting in the absence of regulation.
Tokenization has the potential to address this head-on through the technological infrastructure of different blockchain networks. These networks can match, convert and automate compliance protocols seamlessly — essentially using technology to regulate technology, making RWA cross-border transactions more secure. This innovation is revolutionizing payment processing, ensuring security and compliance with the stringent requirements of the Payment Card Industry Data Security Standard (PCI DSS) for protecting cardholder data.
The role of trust for tokenization and sensitive data
Trust is a key factor in any working economy, but it’s particularly significant in the world of fintech and tokenization, where so much of the back-end engineering can’t be seen.
To foster confidence and interoperability, governments, central banks and industry advocates are calling for widespread adoption of an agreed-upon standard. By utilizing tokenization to replace sensitive information like the primary account number (PAN) with randomly generated tokens, this technology ensures that sensitive financial information is secured, enhancing trust in digital transactions. This process not only protects the primary account number but also secures a variety of sensitive information, including credit card data, bank account information and even medical records through the use of tokenized data. Unlike traditional encryption, tokenized data is non-reversible and does not rely on a mathematical algorithm that could be broken, thereby offering superior security benefits.
Regtech can also bolster the tokenization of RWA by implementing financial crime controls such as identity verification, fraud prevention and international sanctions screening. Implementing such regtech solutions requires careful consideration of RWA valuation methodologies, legal compliance and trade tariffs.
From real estate and stamp collections to mining rights and music catalogs, the tokenization of RWA unlocks new avenues for investment, increases transparency for asset managers and provides a safer and more accessible playing field. With a standardized, well-regulated system connecting blockchain networks, tokenization could reshape markets and promote opportunity for more people than ever before.
