Introduction
In the rapidly evolving landscape of digital assets, the concept of tokenized money has emerged as a transformative force, reshaping the way we perceive and interact with currency. As central banks, commercial banks, and fintechs navigate this new frontier, the need for a unified framework that seamlessly integrates various forms of digital currencies has become increasingly apparent.
The white paper “Achieving Uniformity of Tokenized Money Through Smart Contracts” by Fireblocks presents a groundbreaking model that not only addresses this need but also paves the way for the future of money.
State of Digital Assets
The evolution of digital assets has been marked by a transformative journey that has reshaped the financial landscape and captured the attention of every part of the financial system. In response to investor demand, the biggest banks and asset managers in the world have sought to offer access to crypto assets. Meanwhile, declines in crypto prices and speculative activity over the past 18 months have created space for corporates and financial institutions to focus on the utility offered by digital assets.
The proliferation of digital assets has not only expanded the investment landscape but has also sparked a paradigm shift in the way we perceive and interact with money. As the digital asset industry continues to gain momentum, it has become increasingly intertwined with traditional financial systems, prompting central banks and regulatory bodies to recognize the potential of digital assets in improving the financial system.
This evolution has set the stage for a future where digital assets play a pivotal role in shaping the global economy, offering new avenues for investment, innovation, and financial inclusion. As the digital asset ecosystem continues to mature, it is poised to redefine the very fabric of finance, unlocking new opportunities and possibilities for individuals and institutions alike.
The Economic and Regulatory Framework
The economic and regulatory framework is a critical consideration in the evolution of tokenized money. The report emphasizes the need for a model that accommodates both wholesale and retail central bank digital currencies (CBDCs), alongside tokenized deposits and stablecoins. By acknowledging the diverse nature of digital currencies and the regulatory considerations surrounding them, the report sets the stage for a comprehensive and inclusive approach to the future of money.
The report recognizes the growing demand from businesses, consumers, and governments to reduce their reliance on a single currency or economy. The emergence of CBDCs and stablecoins represents a larger shift to a diversified world economy, where many types of currencies, whether decentralized or state-issued, live alongside each other. As a result, a “basket of currencies” approach in global finance will likely evolve, requiring mechanisms of interactions between stablecoins, central bank digital currencies (CBDCs), cryptocurrencies, and fiat currencies.
Governments have sped up their exploration of CBDCs to increase efficiency, decrease transaction costs, and speed up settlement times. But the continued and future operation of CBDC and stablecoin networks will require the expansion of resilient and secure cloud-based infrastructures, regardless of whether the architecture is centralized or based on a distributed ledger template. The report showcases the latest developments and innovations in this field, illustrating how it may look as the tokenization of money through smart contracts becomes a reality.
Overall, the economic and regulatory framework is a critical consideration in the evolution of tokenized money. The report recognizes the diverse nature of digital currencies and the regulatory considerations surrounding them, emphasizing the need for a comprehensive and inclusive approach to the future of money.
The Model: A Simplified Digital Monetary System
The simplified digital monetary system model presented in the report depicts a closed economy with a single national currency, governed by a central bank responsible for authorizing and regulating banks.
The model incorporates a fractional reserve banking system and allows for competition from non-bank fintechs, which offer payment services to consumers but are not permitted to perform maturity transformation, thereby presenting a lower degree of risk to the financial system. Similar to existing e-money regimes in many countries, customer deposits held by these fintechs must be fully-backed and bankruptcy-remote from the fintech to protect the consumer.
In this model, there are two banks, alpha and beta, and a non-bank fintech, gamma, each with a set of customers. These institutions are allowed to issue digital tokens: alpha coin, beta coin, and gamma coin, respectively. The monetary system is governed by a central bank that issues a wholesale central bank digital currency (CBDC).
The model illustrates the flows of funds between customers and the different forms of tokenized money, including CBDC reserves, alpha coin, beta coin, and gamma coin. It provides a simplified representation of how these entities interact within the digital monetary system, highlighting the roles of banks, fintechs, and the central bank in issuing and managing digital tokens and reserves.
The Smart Contracts Describing the Model
The model presented in the report uses smart contracts to ensure tokens with different backing ratios are interchangeable and behave according to a set of pre-programmed rules to preserve uniformity of value. The smart contracts are pieces of code on a blockchain platform that define rules, conditions, and functions, like any other software.
However, their self-executing nature sets them apart. When certain conditions specified in the smart contract’s code are met and verified on the blockchain, the contract automatically triggers the pre-programmed actions. These actions could involve transferring digital assets between parties, updating data on the blockchain, or executing complex multi-step processes.
The smart contracts in the model are designed to ensure that tokens issued by banks and non-banks are programmatically guaranteed by the wholesale CBDC, providing a clear and transparent illustration of the implications of banking regulation.
The smart contracts also use a whitelist in the alpha coin, beta coin, and gamma coin smart contracts to ensure that the banks and fintechs in the model only interact with known customer wallets and thereby adhere to KYC rules. This helps to ensure that non-customers cannot hold the coins issued by these institutions.
The smart contracts in the model are designed to be interoperable, using the ERC-20 token standard for all fungible tokens (units of account) within the model. This standard provides a common framework and rules for creating and interacting with tokens on the Ethereum platform, improving interoperability and ease of adoption.
Illustrative Flows of Funds Between Customers
In this section, the report provides illustrative flows of funds between customers within the digital monetary system. It offers a practical demonstration of how CBDCs, tokenized deposits, and stablecoins can seamlessly circulate among users, underpinned by the smart contract logic. By visualizing these flows, the report brings to life the operational dynamics of the proposed model, showcasing its potential to revolutionize the way individuals transact and interact with digital currencies.
Considerations and Extensions Around Privacy
Privacy is a top priority for most central banks and emphasizes the importance of addressing privacy concerns in the design and implementation of digital currencies and tokenized money systems.
The model presented in the report does not delve deeply into privacy considerations, but it highlights the significance of privacy for central banks, commercial banks, and other financial intermediaries. It recognizes that these entities would be unwilling to interact with an infrastructure that revealed their balances and transactions to their competitors. Additionally, it acknowledges the importance of privacy in ensuring public trust and adoption of retail CBDCs.
The report also discusses the distinction between privacy and anonymity, noting that while central banks could never implement a completely anonymous payment token due to regulatory requirements, they are exploring technological solutions that give individuals greater control of their data in a way that can both enable identification and enhance privacy. This nuanced approach aims to address privacy concerns while complying with regulatory frameworks.
Furthermore, the report highlights cutting-edge technologies such as zero-knowledge proofs as potential tools to enhance privacy.
Zero-knowledge proofs can provide an additional degree of privacy through the encryption of wallet addresses and transaction details, protecting individuals’ identity and transactions from others on the blockchain while enabling the sharing of specific information with the recipient or their wallet provider to comply with regulations. The report suggests that these technologies, while not yet widely tested or available at scale, could offer valuable propositions for enhancing individual privacy in the digital asset ecosystem.
Conclusion
In conclusion, the white paper “Achieving Uniformity of Tokenized Money Through Smart Contracts” presents a compelling vision for the future of money. By embracing the potential of smart contracts and digital asset interoperability, the model outlined in the report offers a transformative framework that unifies diverse forms of digital currencies. It empowers central banks, commercial banks, and fintechs to navigate the evolving landscape of digital assets while preserving the integrity and uniformity of money. As we stand on the cusp of a new era in finance, the ideas presented in this paper serve as a guiding light, propelling us toward a future where the boundaries of money are redefined, and opportunities abound.
