Performance of Digital Currency and Improvements : An analysis of current implementations and the future of digital currency

Abstract: Currency has changed a lot, and the introduction of the Internet sped up the evolution of the currency. Digital currency introduced many benefits compared to physical currencies. Ideas such as cryptocurrencies work as an option for other means of payment. During the recent pandemic, interest in new digital currencies has increased, leading to more research on digital currency. With the introduction of new currencies and their increased popularity, many central banks have started looking into the idea of innovating currency. All this new research has coined the term central bank digital currency. As of today, there is no single idea on how a digital currency should work or be implemented. With many variations, the future is still unclear. There seem to be vulnerabilities to solve and many potential ways to improve current systems. When building this new currency it is crucial to know what different use cases could demand from the implementation. In conclusion, the results show that digital currency is still in early development, with central bank digital currency research showing promise. It is theoretically possible to create a better transaction solution contra traditional currencies. More research is needed on the topic of digital currency, but there could be incremental improvements to today’s currency leading to better future solutions.
