A cryptocurrency is a digital or virtual form of currency that uses cryptography for security and operates on a decentralized network, typically a blockchain. Unlike traditional currencies issued by governments (fiat), cryptocurrencies are not controlled by any central authority.
How It Works
Cryptocurrencies use various consensus mechanisms to validate transactions and maintain the integrity of their networks. Users hold their crypto in digital wallets identified by public and private key pairs.
Key Properties
Decentralization: No central bank or government controls the currency.
Transparency: All transactions are recorded on a public ledger.
Pseudonymity: Users transact via wallet addresses rather than personal identities.
Global Access: Anyone with an internet connection can participate.
Use Cases
Cryptocurrencies serve as digital money, stores of value, investment assets, governance tools for decentralized protocols, and fuel for decentralized applications (dApps).
