What Is Cryptocurrency?

Cryptocurrency refers to digital or virtual currencies secured by cryptography, making them nearly impossible to counterfeit or double-spend. Unlike traditional government-issued currencies like the dollar or euro, most cryptocurrencies operate on decentralized networks built on blockchain technology—a distributed ledger maintained by computers worldwide.

The key characteristic of cryptocurrency is that it generally does not require a central authority, such as a bank or government, to verify transactions. Instead, it relies on advanced encryption to secure transactions, control the issuance of new units, and transparently verify asset transfers. This encryption enables cryptocurrency to function both as a form of currency and as a virtual accounting system that anyone can audit.

Cryptocurrency was partly developed in response to concerns about the traditional financial system following the global financial crisis in 2008. In January 2009, Bitcoin was launched by the anonymous creator Satoshi Nakamoto, establishing the foundation for revolutionary financial technology. Its core innovation is a system that allows two parties to exchange value directly, without trusted intermediaries like banks or financial institutions.

Traditional currencies, known as fiat currency, derive value from government backing and regulation.
