What is Cryptocurrency?
Definition
Cryptocurrency is a digital or virtual form of money secured by cryptography and built on decentralized blockchain networks. Unlike traditional fiat currencies (USD, EUR, etc.), cryptocurrencies operate without central banks or intermediaries, enabling peer-to-peer transactions.
Key Features of Cryptocurrency
- Decentralization – No single entity controls the network, reducing censorship and manipulation risks.
- Blockchain Technology – A transparent, immutable ledger records all transactions securely.
- Limited Supply – Many cryptos (like Bitcoin) have a fixed supply, creating scarcity similar to gold.
- Fast & Low-Cost Transactions – Cross-border payments are quicker and cheaper than traditional banking.
- Smart Contracts – Platforms like Ethereum allow self-executing contracts for DeFi, NFTs, and more.
How Does Cryptocurrency Work?
Cryptocurrencies rely on blockchain technology, where transactions are verified by a decentralized network of nodes. The two most common consensus mechanisms are:
- Proof of Work (PoW) – Miners solve complex puzzles to validate transactions (e.g., Bitcoin).
- Proof of Stake (PoS) – Validators stake coins to secure the network (e.g., Ethereum 2.0).
Once confirmed, transactions are permanently recorded on the blockchain, ensuring security and transparency.
