Cryptocurrency, often referred to as crypto, is decentralized digital money powered by blockchain technology. It enables peer-to-peer payments without intermediaries like banks. While Bitcoin remains the most prominent example—created through mining—other cryptocurrencies may use alternative methods.
Understanding Cryptocurrency Fundamentals
Decentralization: The Core Principle
Unlike traditional currencies (e.g., the US dollar), cryptocurrencies:
- Lack physical form.
- Aren’t controlled by central authorities (e.g., governments or banks).
- Operate on a blockchain—a tamper-proof public ledger updated across a global network of computers.
How Blockchain Works:
- Transactions are grouped into "blocks."
- Each block is cryptographically linked to the previous one (forming a "chain").
- Bitcoin adds blocks every 10 minutes; other cryptos vary.
- Consensus mechanisms (e.g., Proof of Work) validate transactions.
