Introduction to Cryptocurrency
Cryptocurrencies are digital tokens designed to facilitate peer-to-peer transactions without intermediaries like banks. Unlike traditional currencies, they exist purely as digital entries in an online ledger called a blockchain. This decentralized system ensures transparency and security by validating transactions across a network of computers.
Key Features:
- Decentralization: No central authority controls cryptocurrencies.
- Security: Transactions are encrypted and immutable once recorded.
- Global Accessibility: Cryptos can be used worldwide without restrictions.
How Cryptocurrency Works
Blockchain Technology
At the heart of cryptocurrencies is blockchain—a distributed ledger maintained by a network of nodes (computers). Each transaction is verified by consensus, ensuring accuracy before being added to the chain.
Wallets and Transactions
Cryptocurrencies are stored in digital wallets, which use private keys to authorize transfers. Payments are direct between users, reducing fees and processing times.

New cryptos enter circulation through mining, a computational process that validates transactions and maintains the blockchain. For example, Bitcoin has a fixed supply of 21 million coins, mimicking the scarcity of gold.
