What are Cryptocurrencies?
Cryptocurrencies are decentralized digital currencies that rely on Blockchain technology to record and secure transactions. Unlike traditional currencies like the dollar or euro, they are not issued by governments or central banks but operate on a Peer-to-Peer (P2P) system, making them resistant to censorship and inflation.
The most famous cryptocurrency is Bitcoin (BTC), which appeared in 2009 by an anonymous person known as Satoshi Nakamoto. Since then, thousands of other cryptocurrencies have emerged, such as Ethereum (ETH), Ripple (XRP), and Litecoin (LTC).
How Do Cryptocurrencies Work?
Cryptocurrencies rely on Blockchain technology, which is a secure digital ledger that records all transactions in blocks linked together in a chain-like manner.
Key Features of Cryptocurrencies:
- Decentralization: No central authority controls them (like banks).
- Cryptography: They use strong encryption algorithms to protect transactions.
- Transparency: All transactions are recorded and traceable (but the identities of the parties may be anonymous).
- Limited Supply: Some currencies like Bitcoin have a maximum limit (only 21 million units).
