What is a CBDC in crypto?

A Central Bank Digital Currency (CBDC) is a digital form of fiat money issued by a central bank. Unlike cryptocurrencies like Bitcoin or Ethereum, which are decentralized and operate on blockchain technology, CBDCs are centralized and regulated by government authorities.

They are designed to complement or replace physical cash and aim to offer a more efficient, secure, and accessible monetary system. Central banks issue CBDCs, maintaining full control over the supply and regulation. This ensures that the digital currency aligns with national monetary policies and financial regulations.

How does a CBDC work?

Individuals and businesses hold CBDCs in digital wallets, which can be provided by central banks, commercial banks, or approved financial institutions. These wallets are similar to bank accounts but specifically designed for digital currency transactions.

Users can transfer CBDCs directly to each other through digital wallets, enabling quick and efficient payments. These assets enable faster and more secure interbank settlements, reducing the need for intermediaries and lowering transaction costs.

CBDCs use advanced encryption techniques to protect against fraud and cyber threats. However, they are not as anonymous as cryptocurrencies. Central banks can track transactions to prevent illegal activities such as money laundering and tax evasion.

These digital currencies integrate with existing financial systems, allowing seamless interaction between digital and traditional banking. This integration supports both online and offline transactions, ensuring accessibility even without internet connectivity.

Differences between CBDCs and stablecoins

Central Bank Digital Currencies (CBDCs) and stablecoins are both digital currencies, but they have fundamental differences in their design, regulation, and purpose.

CBDCs are issued and regulated by central banks, ensuring centralized control that aligns with national monetary policies. Examples include the Digital Yuan by China and the e-Krona by Sweden.

In contrast, stablecoins are issued by private entities or organizations and are backed by assets such as fiat currencies, commodities, or other cryptocurrencies to maintain value stability. Popular stablecoins include Tether (USDT) and USD Coin (USDC).

Regulation is another key differentiator. CBDCs are governed by national and international financial regulations and are subject to strict oversight to prevent financial crimes and ensure monetary stability. Stablecoins, however, face varying degrees of regulation depending on the jurisdiction, often attracting scrutiny for issues related to transparency, reserve management, and compliance.

The purpose and use cases of CBDCs and stablecoins also differ significantly. CBDCs are designed to serve as a digital version of a country’s fiat currency, aiming to improve financial inclusion, enhance payment systems, and support monetary policy implementation.

They are used for both retail and wholesale transactions. Stablecoins, on the other hand, are primarily used to facilitate trading and transactions within the cryptocurrency ecosystem, serving as a bridge between volatile cryptocurrencies and stable fiat currencies. They are popular for cross-border transactions, remittances, and as a store of value in the crypto market.

Technologically, CBDCs utilize centralized systems managed by central banks, which may employ distributed ledger technology (DLT) or traditional databases, depending on the design. Stablecoins typically use blockchain technology and operate on various decentralized platforms, with smart contracts managing issuance, redemption, and transactions.

Security and trust are also distinguishing factors. CBDCs benefit from the trust and credibility of central banks, employing robust security measures and regulatory compliance to safeguard against fraud and cyber threats. Trust in stablecoins depends on the issuer’s reputation and transparency, with security practices varying widely. Some stablecoins have faced issues related to reserve backing and regulatory scrutiny.
