Crypto, short for cryptocurrency, is a form of digital money that uses advanced encryption (cryptography) to secure transactions and control the creation of new units. Unlike traditional currencies issued by governments, crypto operates on decentralized networks called blockchains, which record every transaction transparently and permanently.
Key Features
- Blockchain technology: A distributed ledger that ensures trust without a central authority.
- Decentralization: No single entity (like a bank or government) controls the system.
- Cryptography: Protects data and verifies ownership.
- Digital wallets: Used to store and send crypto securely.
- Mining and validation: Processes that confirm transactions and create new coins.
