What is Cryptocurrency?

Cryptocurrency is a digital currency that exists only online. Unlike traditional currencies such as the dollar or rupee, cryptocurrencies are decentralized, meaning no government or bank controls them. They use cryptography (advanced coding techniques) to secure transactions and manage the creation of new units.

Some of the most popular cryptocurrencies are:

Bitcoin (BTC) — The first and most famous cryptocurrency.

Ethereum (ETH) — Known for smart contracts and decentralized apps.

Solana (SOL) — Fast and low-cost blockchain network.

Ripple (XRP) — Used for international money transfers.

Dogecoin (DOGE) — A meme coin that became famous.

How Does Cryptocurrency Work?

Cryptocurrencies run on blockchain technology. A blockchain is like a public digital ledger where all transactions are recorded. This ledger is maintained by a network of computers (called nodes) around the world.

Key components of cryptocurrency:

1. Blockchain:
It stores all transaction data. Once a transaction is added to the blockchain, it cannot be changed.


2. Decentralization:
No single authority controls cryptocurrencies. Instead, thousands of computers maintain the system, making it very secure and transparent.


3. Private and Public Keys:
To use cryptocurrency, you need a wallet that contains a public key (your address) and a private key (your password). This keeps your funds safe.


4. Mining:
Some cryptocurrencies like Bitcoin are created through a process called mining, where computers solve complex math problems to validate transactions.
