Introduction to Cryptocurrency

In simple words, cryptocurrency is a type of digital currency that is secured by cryptography. Unlike traditional money issued by governments and central banks, cryptocurrency is decentralized and operates on a technology called blockchain.

This means no single authority, like a government or bank, controls cryptocurrency. Instead, it is powered by a network of computers that record transactions securely and transparently.

For example, Bitcoin, the first cryptocurrency, was launched in 2009 by an anonymous person or group named Satoshi Nakamoto. Since then, thousands of cryptocurrencies have been created, each serving different purposes.

History and Evolution of Cryptocurrency

The idea of digital money is not new, but cryptocurrency brought something revolutionary.

• 1980s: The concept of digital cash was first introduced.

• 1990s: Several attempts were made to create digital money, but none were successful.

• 2009: Bitcoin was launched, marking the beginning of true cryptocurrency.

• 2010s: Cryptocurrencies like Ethereum, Ripple, and Litecoin emerged.

• 2020 onwards: Crypto became mainstream, with big companies and investors adopting it.

Today, cryptocurrencies are used not only for trading but also for payments, investments, gaming, decentralized finance (DeFi), and more.

How Cryptocurrency Works

At its core, cryptocurrency works on blockchain technology. A blockchain is a digital ledger where all transactions are recorded in blocks and linked together in a chain.

Here’s how it works step by step:

1. Transaction Initiation: A user sends cryptocurrency from one wallet to another.

2. Verification: The transaction is verified by computers (called nodes) in the network.

3. Block Creation: Once verified, the transaction is grouped into a block.

4. Blockchain Update: The block is added to the existing chain of blocks, making it permanent.

5. Completion: The receiver gets the cryptocurrency in their wallet.

This system makes cryptocurrency secure, transparent, and nearly impossible to tamper with.
