What Is Cryptocurrency?
Cryptocurrency is a digital currency that uses cryptography for security, making it nearly impossible to counterfeit or double-spend. Most operate on decentralized blockchain networks—distributed ledgers maintained by a network of computers.
Key features:
- Decentralization: No central authority controls cryptocurrencies, reducing government interference.
- Disruptive Potential: Blockchain technology could revolutionize finance, law, and other sectors.
- Pros: Lower transaction costs, faster transfers, and resilience against single points of failure.
- Cons: Price volatility, high energy consumption for mining, and potential misuse in illegal activities.
How Cryptocurrency Works
Cryptocurrencies rely on blockchain technology—a chain of blocks recording transactions verified by a network of computers. Each block must be validated before being added, ensuring immutability.
Applications of blockchain extend beyond finance:
- Supply chain tracking
- Secure voting systems
- Crowdfunding platforms
Major institutions like JPMorgan use blockchain to streamline payments and cut costs.

Cryptocurrencies serve diverse purposes:
- Utility Tokens (e.g., ETH): Facilitate blockchain operations.

- Governance Tokens (e.g., Uniswap): Enable voting rights.
- Platform Tokens (e.g., Solana): Support decentralized apps.
