There were many attempts to create a digital currency during the tech boom of the 1990s, with systems like Flooz, Beenz, and DigiCash emerging in the market but ultimately failing. There were many reasons for their failure, such as fraud, financial issues, and even friction between company employees and their bosses.

It is noteworthy that all these systems used a trusted third-party approach, meaning that the companies behind them validated and facilitated transactions. Due to the failures of these companies, creating a digital cash system was seen as a hopeless case for a long time.

Then, in early 2009, an unknown programmer or group of programmers under the pseudonym 'Satoshi Nakamoto' introduced 'Bitcoin'. Satoshi described it as a 'peer-to-peer electronic cash system'. It is a completely decentralized system, meaning there are no involved servers and no central controlling authority. This concept closely resembles peer-to-peer networks for file sharing.
