## 🔍 What Is Cryptocurrency?

Cryptocurrency is a **digital or virtual form of money** that uses **cryptography** for security and operates on decentralized networks based on **blockchain technology**. Unlike traditional currencies issued by governments (like the USD or EUR), cryptocurrencies are not controlled by any central authority — making them resistant to censorship and inflation.

> 💬 *"Bitcoin introduced the idea of a digital currency you can send peer-to-peer without banks. Now, crypto powers everything from finance to games."*

Today, there are over **10,000 cryptocurrencies**, including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), and emerging tokens from DeFi, NFTs, and AI-blockchain projects.

## ⚙️ How Does Cryptocurrency Work?

At its core, crypto runs on a **blockchain** — a public, distributed ledger that records every transaction across a network of computers.

### Key Components:

| Term | Explanation |

|------|-------------|

| **Blockchain** | A chain of blocks storing transaction data. Immutable and transparent. |

| **Decentralization** | No single entity controls the network — powered by nodes worldwide. |

| **Cryptography** | Secures transactions and controls new coin creation (e.g., SHA-256). |

| **Consensus Mechanisms** | Rules that validate transactions: <br> ✅ **Proof of Work (PoW)** – Bitcoin <br> ✅ **Proof of Stake (PoS)** – Ethereum, Cardano |

When you send crypto, the transaction is verified by validators (miners or stakers) and added to the blockchain — forever recorded and nearly impossible to alter.
