What Is Cryptocurrency?
Cryptocurrency is a digital or virtual currency secured by cryptography, making it nearly impossible to counterfeit. Unlike traditional currencies issued by governments (like the rupee or dollar), cryptocurrencies operate on decentralized networks called blockchains. Bitcoin, launched in 2009, was the first cryptocurrency, but today, thousands of alternatives (altcoins) like Ethereum and Solana exist.
How Does Cryptocurrency Work?
Cryptocurrencies rely on blockchain technology—a distributed ledger that records transactions across a network of computers. Here’s how it works:
- Transactions: Users send/receive crypto via digital wallets.
- Verification: Miners or validators confirm transactions using consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).
- Block Creation: Verified transactions are grouped into blocks and added to the blockchain.
- Decentralization: No central authority controls the network, ensuring transparency and security.
