1. How Cryptocurrency Works
Cryptocurrencies operate on decentralized networks, meaning no single entity (like a bank or government) controls them. Transactions are verified using blockchain technology, ensuring security, transparency, and immutability.
✅ Blockchain Technology
A blockchain is a distributed ledger where transactions are recorded in blocks and linked together in a chain. It ensures:
- Security (using cryptographic hashing)
- Transparency (publicly accessible transaction records)
- Decentralization (no single point of control)
Some blockchain types:
- Public Blockchains – Open to anyone (e.g., Bitcoin, Ethereum).
- Private Blockchains – Restricted access for enterprises (e.g., Hyperledger).
- Hybrid Blockchains – A mix of both (e.g., Ripple).
🔹 2. Types of Cryptocurrencies
There are thousands of cryptocurrencies, but they generally fall into these categories:
🔥 Major Cryptocurrencies
- Bitcoin (BTC) – The first and largest crypto, often seen as a store of value.
- Ethereum (ETH) – Powers smart contracts and decentralized apps (DApps).
- Binance Coin (BNB) – Used on the Binance exchange and its ecosystem.
- Solana (SOL) – A fast blockchain focused on scalability.
- Cardano (ADA) – A research-driven blockchain emphasizing sustainability.
🏦 Stablecoins (Cryptos pegged to stable assets)
- Tether (USDT), USD Coin (USDC), DAI – Pegged to the U.S. dollar to reduce volatility.
🤑 Meme Coins
- Dogecoin (DOGE), Shiba Inu (SHIB) – Started as jokes but gained large communities.
💰 Privacy Coins (Focus on anonymous transactions)
- Monero (XMR), Zcash (ZEC) – Hide sender/receiver details and transaction amounts.
🔧 Utility Tokens (Used within platforms)
- Chainlink (LINK) – Provides real-world data to smart contracts.
- Polygon (MATIC) – Improves Ethereum’s scalability.
