Challenges and Opportunities of Central Bank Digital Currencies (CBDCs) and Digital Identity Systems: A Comprehensive Analysis

A Central Bank Digital Currency (CBDC) is a digital version of a nation’s currency issued and backed by the country’s central bank. It can be used in the same way as physical cash, but can be stored and transferred electronically. Many countries are considering CBDCs as a means to modernize their payment systems and enhance financial inclusion. However, the actual implementation and use of CBDCs are still in development and subject to regulatory approval.

CBDCs are programmable forms of digital currency, similar to cryptocurrencies like Bitcoin or Ethereum. They can have restrictions on specific purchases. Nevertheless, they do not represent personal ownership.

Currently, cashless digital transactions are conducted using credit cards and debit cards, which escape external control unlike CBDCs.

CBDCs facilitate comprehensive digital monitoring and control of expenditures, leading to the recording of each transaction. This is absent in cryptocurrencies, as anonymity is lacking.

CBDCs could be assigned a carbon score limiting purchases of items such as gasoline or meat.

CBDCs could be geographically restricted, potentially curtailing travel freedom. Digital IDs, based on personal information and biometric data, could serve for identification across various domains.

However, CBDCs and digital IDs raise concerns about data privacy, security, and potential misuse. Data collection and storage could be vulnerable to hacking. There’s the risk of identity theft, fraud, and unauthorized access. Misuse through government surveillance or discrimination is also possible.

Critics see the potential for privacy and civil liberties violations due to the monitoring of financial transactions. CBDCs could increase governmental control over transactions and limit financial freedoms. Censorship resistance could be compromised, as central entities might block transactions.

The combination of CBDCs and digital IDs could lead to adverse effects. Privacy risks could stem from data storage and potential abuse. Moreover, it could centralize control over financial systems and undermine decentralization and democratic control, qualities valued by many proponents of digital currencies. Finally, it could result in financial exclusion for those lacking access to digital IDs or those unwilling to disclose their personal information.
