1. What is Cryptocurrency?
Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Unlike traditional currencies issued by governments (like the US dollar or the euro), cryptocurrencies operate on decentralized networks based on blockchain technology.
2. How Cryptocurrencies Work
2.1 Blockchain Technology
At the heart of every cryptocurrency lies blockchain technology. A blockchain is a distributed ledger that records all transactions across a network of computers. This ensures that the transaction history of each coin is transparent and immutable.
2.2 Mining and Transaction Processes
Mining is the process through which new cryptocurrency coins are created and transactions are verified. Miners use powerful computers to solve complex mathematical problems, which in turn validate transactions and add them to the blockchain.
3. Popular Cryptocurrencies
3.1 Bitcoin
Bitcoin, created in 2009 by an anonymous person (or group) known as Satoshi Nakamoto, is the first and most well-known cryptocurrency. It’s often referred to as digital gold due to its limited supply of 21 million coins.
3.2 Ethereum
Launched in 2015 by Vitalik Buterin, Ethereum is more than just a digital currency. It’s a decentralized platform that enables smart contracts and decentralized applications (DApps) to be built and run without any downtime, fraud, control, or interference from a third party.
3.3 Altcoins
Apart from Bitcoin and Ethereum, there are thousands of alternative cryptocurrencies known as altcoins. These include Litecoin, Ripple (XRP), Cardano, and many more, each with unique features and use cases.
