What Is Cryptocurrency?
A cryptocurrency is a digital or virtual currency that uses cryptography to secure transactions and verify ownership. Unlike traditional currencies such as the US Dollar or Indian Rupee, cryptocurrencies are not controlled by a central bank or government.
Instead, they operate on decentralized blockchain networks where every transaction is recorded in a transparent and immutable digital ledger. This technology allows anyone with an internet connection to send or receive cryptocurrency anywhere in the world without requiring permission from a financial institution.
Each cryptocurrency has its own purpose. Some are designed as digital money, while others power decentralized applications, smart contracts, payments, gaming, or financial services.
Why Was Cryptocurrency Created?
Traditional financial systems rely on banks and payment processors to verify and complete transactions. While these systems have supported global commerce for decades, they also have limitations, including slower international transfers, higher transaction fees, limited operating hours, and reliance on centralized institutions.
Cryptocurrency was introduced to create a more open and decentralized financial system where users can control their own assets and transfer value directly to one another.
The publication of the Bitcoin whitepaper by Satoshi Nakamoto in 2008 introduced a new approach to digital payments by solving the long-standing problem of digital double spending without requiring a trusted third party.
