Achieving Uniformity of Tokenized Money Through Smart Contracts

The white paper titled "Achieving Uniformity of Tokenized Money Through Smart Contracts" explores the interaction between Central Bank Digital Currencies (CBDCs), tokenized deposits, and stablecoins in a future digital financial system. It highlights how different forms of money—such as a CBDC, fractionally-backed tokenized deposits issued by commercial banks, and fully-backed stablecoins issued by fintechs—can coexist and be interchangeable in a seamless manner through the use of smart contracts. The goal is to maintain the uniformity of money, ensuring that $10 in any form, whether it be CBDCs, tokenized deposits, or stablecoins, retains the same value for the consumer, no matter the medium of exchange.

1. Uniformity of Money: Traditionally, $10 holds the same value, whether spent in cash, transferred via a bank, or paid through digital means. This concept must be preserved in the realm of tokenized money, where multiple forms of digital currencies are emerging. The white paper emphasizes that maintaining this uniformity is critical in a financial system where people may use different types of tokenized currencies.

2. Digital Asset Ecosystem: The paper envisions a system where a central bank issues a CBDC as a backing asset, commercial banks issue fractionally-backed tokenized deposits, and fintechs issue fully-backed stablecoins. The interplay between these types of currencies requires a system of interoperability so that consumers can use any of them interchangeably without noticing the difference. This is achieved through the implementation of smart contracts.

3. Role of Smart Contracts: Smart contracts are essential for enforcing the convertibility and interoperability between these different forms of tokenized money. The paper proposes a model using the Fireblocks infrastructure to demonstrate how tokenized money can be made interchangeable in real time. The contracts ensure that different types of money are freely convertible while maintaining their value.

4. Convertibility: One of the key features of this system is the convertibility between fractionally-backed tokenized deposits and fully-backed stablecoins. The paper presents a system where a central bank sets the rules for converting between different types of digital assets, such as CBDCs, tokenized deposits, and stablecoins. Through smart contracts, convertibility happens seamlessly so that a user holding a token from one bank can transfer value to another user holding a token from a different bank.

5. Privacy Considerations: Although the focus of this paper is not privacy, it briefly touches on the fact that privacy will need to be addressed as the system develops. The coexistence of CBDCs, stablecoins, and tokenized deposits raises important questions about the level of visibility central banks, commercial banks, and fintechs will have into users' financial activities. In future implementations, privacy protections will likely be integrated into the system.

6. Regulatory Framework: The paper acknowledges the need for regulatory oversight to ensure that the tokenized financial system operates safely and efficiently. Regulation will be critical to ensuring that all forms of tokenized money can coexist while preserving the stability of the financial system. The central bank’s role in issuing CBDCs and overseeing the convertibility of different digital assets will help maintain the integrity of the financial system.

7. Strategic Use Cases: The paper also presents real-world examples and projects that demonstrate the potential of tokenized money. For instance, it references Australia's ANZ bank's issuance of a stablecoin backed by the Australian Dollar and Brazil's pilot CBDC project DREX. These examples highlight how tokenized money is already being experimented with and what the future could look like.

The white paper ultimately argues for a digital financial ecosystem where different forms of tokenized money—CBDCs, tokenized deposits, and stablecoins—can interact seamlessly through the use of smart contracts. This model of free convertibility, regulated by central banks, would preserve the uniformity of money, ensuring that all forms of digital currency can be used interchangeably by consumers. The paper encourages central banks, commercial banks, and fintechs to embrace this future by building the necessary infrastructure and developing the regulatory frameworks that will allow tokenized money to function safely and efficiently in the real world.
