Cryptocurrency, at its core, is a digital or virtual currency that uses cryptography for security. This makes it difficult to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology – a distributed ledger enforced by a network of computers.

Key Characteristics
- Decentralization: Not controlled by a single entity like a central bank.
- Cryptography: Uses encryption to secure transactions.
- Blockchain: A public, distributed ledger recording all transactions.
- Digital: Exists only in digital form.
How it Works
Cryptocurrencies operate using blockchain technology. Each transaction is grouped into a “block,” which is then added to the chain. This process is secured through cryptography, ensuring the integrity of the data.
Mining and Staking
New units of cryptocurrency are often created through a process called “mining” or “staking,” which involves solving complex mathematical problems or validating transactions.
Examples
Bitcoin, Ethereum, Litecoin, and Ripple are examples of popular cryptocurrencies. Each has unique features and use cases.
