CBDCs vs. Cryptocurrencies: Understanding the Key Differences

The rise of digital currencies has led to a fascinating comparison between Central Bank Digital Currencies (CBDCs) and cryptocurrencies. While both are forms of digital currency, they differ significantly in their underlying principles and purpose. Mainly, CBDCs are issued and regulated by central banks, while cryptocurrencies operate on decentralized networks.

In this article, we will delve into the contrasting features of CBDCs and cryptocurrencies, highlighting their unique characteristics, benefits, and the implications they hold for the future of finance.

Centralized Control vs. Decentralization

One of the fundamental distinctions between CBDCs and cryptocurrencies lies in their control and governance.

Centralized control: CBDCs are centralized digital currencies issued and regulated by central banks. They operate within the existing financial system and are subject to governmental policies and regulations. Central banks retain control over the issuance, supply, and management of CBDCs, allowing them to maintain monetary stability and implement monetary policies.

Decentralization: Cryptocurrencies operate on decentralized networks, utilizing blockchain technology. They are not controlled by any central authority, relying instead on a distributed network of nodes to validate transactions. Cryptocurrencies enable peer-to-peer transactions without the need for intermediaries, providing users with more control over their funds and transactions.

In each of these instances there is nuance, of course. A cryptocurrency may be completely decentralized but a person might need to go to an exchange to buy coins or hold them in a wallet controlled by a corporation. This adds a layer of centralization to managing decentralized cryptocurrencies. Similarly, we can start with a decentralized platform at the heart of our national currencies to give people more privacy and control of transactions. But what happens when a person loses their keys? A central authority has to exist to help them recover funds.

Decentralization, the true open ethos of crypto, and centralization, our traditional way of creating and managing money, each come with challenges both ethical, theoretical, and tactical.

In an interview with Jim Zhang, we talked about how this give and take between centralization and decentralization impacts monetary design.

Stability and Value

The stability and value proposition of CBDCs and cryptocurrencies also differ significantly.

Stable value: CBDCs are based on the nation's fiat currency, maintaining a stable value relative to the underlying fiat currency. This stability makes CBDCs more suitable for everyday transactions, as their value remains unaffected by market volatility.

Volatile value: Cryptocurrencies, such as Bitcoin and Ethereum, are known for their price volatility. Their value is determined by market demand and speculative factors, leading to substantial price fluctuations. While this volatility presents investment opportunities, it also poses risks for everyday transactions and store-of-value purposes.

Privacy and Anonymity

Privacy and anonymity are crucial considerations when comparing CBDCs and cryptocurrencies. This is a hotly debated topic, and one of the reasons why some states have passed legislation to pump the brakes on CBDC design.

Privacy features: CBDCs can offer varying levels of privacy, depending on the design choices made by central banks. While some CBDCs prioritize transaction privacy, others may incorporate audit features to facilitate regulatory oversight and prevent illicit activities.

Pseudonymity: Cryptocurrencies are often associated with pseudonymity, as individuals do not need to reveal their identities to use them. In private markets this privacy is attractive, as it feels more anonymous and secure (even though blockchain analysis techniques have proven capable of revealing user identities). It’s this anonymity that causes issues with governments around the world, who see crypto as a potential vehicle for financing illicit activities.

Transaction Speed and Scalability

Transaction speed and scalability are critical factors in assessing the feasibility of CBDCs and cryptocurrencies for everyday use.

Transaction speed: CBDCs can offer near-instantaneous transaction settlement due to their more centralized nature and integration within the existing financial infrastructure. Central banks can leverage technological advancements to provide efficient and rapid payment systems.

Blockchain by its nature is not as fast as centralized databases. But in a consortium of commercial banks with a relatively small number of participants, limitations on throughput become irrelevant and the value of instantaneous transfers is realized.

Our work with Swift is a great example of this. According to the white paper, “thanks to the orchestration capability of our enhanced platform, we can further develop the solution to enable the escrow fund to be orchestrated simultaneously.” Meaning, in short, we can train the machine to know the state of different accounts, settle transactions automatically, and do so quickly.

Transaction scalability: Cryptocurrencies, particularly popular ones like Bitcoin, face challenges regarding transaction scalability. The limited transaction throughput and block size restrictions can result in delays during periods of high demand, hindering their suitability for widespread everyday transactions. Unlike CBDCs, broader consensus is needed for each transaction, which takes more time in a public space than in a contained, private ecosystem.

Kaleido Powers CBDC Design and Development

CBDCs and cryptocurrencies represent two distinct approaches to digital currencies. Cryptocurrencies emphasize decentralization, user autonomy, and potential. On the other hand, CBDCs offer the benefits of stability, control, and regulatory oversight, making them suitable for everyday transactions within existing financial systems.

Kaleido’s CBDC Platform enables central and commercial banks to create their own CBDCs quickly and fully customize network design. This includes features for secure messaging, token types and transfers, and various privacy constructs. We enable central banks to efficiently explore various use cases, transition to production faster, and reduce development time and costs dramatically.
