Abstract [en]

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.

Abstract [sv]

Valuta har förändrats genom tiderna och introductionen av internet skyndade på denna utveckling. Digital valuta har introducerat många fördelar jämfört med fysiska valutor. Fler idéer som till exempel kryptovalutor har introducerats som alternativa betalmedel. Under den senaste pandemin så har intresset för nya digitala valutor ökat, vilket har lett till mer forskning inom området av digitala valutor. På grund av växande popularitet och nya digitala valutor så har många central banker börjat testa idéen om att nyskapa valuta, och med detta så har termen centralbanks valuta skapats. Det finns inte idag en enda lösning på hur digitala valutor ska fungera eller bli implementerade. Med många varianter så är framtiden fortfarande oklar. Det verkar finnas problem att lösa och många möjliga sätt att förbättra existerande system. Vid byggandet av denna nya valuta så är det extremt viktigt att veta vad som är viktigt och hur det kan finnas olika krav beroende på hur valutan ska användas. Enligt resultaten så är digital valuta fortfarande tidigt i sin utveckling och forsking gällande centralbanks styrda digitala valutor verkar lovande. Mer forsking kommer att behövas inom området digital valuta, men det kan komma många små förbättringar på dagens valuta som leder till bättre framtida lösningar.
