What is Cryptocurrency?
Cryptocurrency is a digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized networks based on blockchain technology.
Bitcoin, the first cryptocurrency, was introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. Since then, thousands of cryptocurrencies have emerged, each with unique features and use cases.
How Does Cryptocurrency Work?
Cryptocurrencies work using blockchain technology—a decentralized digital ledger that records all transactions across a network of computers. Each transaction is verified by nodes through cryptographic methods to ensure data integrity and prevent fraud.
Once verified, transactions are grouped into a ‘block.’ Each block is connected to the previous one, forming a secure, unchangeable chain of records.
