The concept of money has undergone significant evolution throughout history. Initially, societies relied on barter systems, where goods and services were exchanged directly. However, this system had limitations, leading to the introduction of commodity money, such as gold and silver, which had intrinsic value. Over time, representative money emerged, allowing paper notes to represent a claim on a commodity. In the modern era, fiat money has become prevalent, where currency has value not because of physical backing but due to government decree. The rise of digital currencies and cryptocurrencies marks the latest evolution, challenging traditional notions of money and payment systems.
