Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. The backbone of most cryptocurrencies is blockchain technology—a decentralized ledger that records all transactions across a network of computers.
When someone sends cryptocurrency, the transaction is verified by network nodes through cryptography and recorded on the blockchain. This ensures transparency and prevents fraud or double spending.
Users store their crypto in digital wallets, which can be either online (hot wallets) or offline (cold wallets). Each wallet has a private key that must be kept secure to protect funds.
Mining is another key concept. It is the process by which new coins are created and transactions are validated. While Bitcoin uses mining, many newer cryptocurrencies use more energy-efficient methods like staking.
Understanding these basics helps beginners navigate the crypto world safely and confidently
