cryptocurrency

Cryptocurrency is a form of digital or virtual currency secured by cryptography, making it nearly impossible to counterfeit. Unlike traditional currencies issued and controlled by a central authority like a government or central bank, cryptocurrencies operate on a decentralized, peer-to-peer network. This system is built on a technology called blockchain, a distributed public ledger that records and verifies every transaction across numerous computers.

This cryptographic security ensures the integrity and immutability of the network, preventing fraud and double-spending. While the most famous cryptocurrency, Bitcoin, was created as an alternative to traditional money, the ecosystem has expanded to include thousands of different types. These range from “altcoins” that offer new functionalities to “stablecoins” pegged to real-world assets like the U.S. dollar to minimize price volatility.

The use of cryptocurrency extends beyond simple payments to a new financial system built on blockchain, including decentralized finance (DeFi), where users can lend, borrow, and trade without intermediaries.
