What Is Cryptocurrency? A Beginner’s Guide
Cryptocurrency is a form of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (like the U.S. dollar or the euro), cryptocurrencies operate on decentralized networks based on blockchain technology. This means they are not controlled by any central authority, making transactions more transparent and less susceptible to interference or fraud.
How Does Cryptocurrency Work?
At the heart of cryptocurrency is blockchain technology—a distributed ledger that records all transactions across a network of computers. Each transaction is grouped into a “block,” which is then linked to the previous block, forming a chain. This structure ensures that once data is recorded, it cannot be altered retroactively without the consensus of the network, providing security and transparency.
Key Features of Cryptocurrencies:
- Decentralization: No single entity controls the network.
- Transparency: All transactions are recorded on a public ledger.
- Security: Advanced cryptographic techniques protect transactions.
- Anonymity: Users can make transactions without revealing personal information.

While Bitcoin is the most well-known cryptocurrency, thousands of others exist, each with unique features and uses. Here’s a comparison of some popular cryptocurrencies:
| Cryptocurrency | Year Launched | Notable Features |
