The Infosys chairman discusses how Blockchain and cryptography can transform traditional financial systems

• Nilekani highlights tokenization as a way to secure digital assets, bridging traditional finance and blockchain technology.
• Unified ledgers enable seamless, high-confidence transactions across platforms, improving asset management efficiency.
• Nilekani emphasizes the importance of combining cryptography with traditional finance to create a scalable, secure system.

Nandan Nilekani, Chairman of Infosys, has shed light on the integration of cryptography and blockchain into traditional financial systems. He emphasized that the Internet allows individuals to manage a wide range of assets, including user-controlled content, NFTs and regulated assets such as financial products.

According to Nilekani, the key to protecting these assets lies in leveraging advances in cryptography, enabling secure and immutable transactions. This approach aims to combine the benefits of tokenization with the robustness of regulated financial environments, creating a new paradigm for asset management.

Tokenization: a bridge between digital and physical worlds

Nilekani highlighted how tokenization allows assets to retain all their attributes in a digital format, similar to a traditional paper file of ownership data. In the digital world, tokenization enables self-contained packages that securely represent these assets.

He noted that this is made possible by advances in cryptography, which ensures that tokens remain immutable and verifiable. Blockchain technology plays a crucial role in this process, providing security and privacy while enabling the creation of digital tokens that have the same trust as their physical counterparts.

Unified Ledgers and Interledger transactions

A notable aspect of Nilekani’s vision involves the use of unified ledgers, which enable seamless transactions between different ledgers. He clarified that these ledgers can be based on different technologies, and are not limited to a single platform like Ethereum.

The unified ledger system allows banks, companies and asset managers to tokenize assets such as deposits, shares or real estate. These tokens can then be traded across different ledgers via established protocols. This system aims to provide a high-trust environment where tokenized assets can be easily traded, reducing friction and increasing adoption.

Trust and governance in a tokenized financial system

Nilekani also emphasized the importance of trust and governance in this new financial architecture. He pointed out that while tokenization itself provides a layer of trust through immutability, additional trust services are needed to validate the authenticity of tokenized assets.

For example, a certificate of provenance can verify a work of art, or a certification can confirm ownership of real estate. This two-layer trust system ensures that transactions remain safe and reliable within the regulated financial framework. Furthermore, this architecture enables large-scale and low-cost transactions, making it a scalable solution for integrating blockchain into traditional finance.

This approach, as Nilekani described, is not about creating a parallel economy, but rather about improving the current system with the strengths of cryptography and tokenization. As a result, it provides a streamlined, secure and interoperable way to manage assets in the digital age.
