It uses cryptography to ensure transaction security, consensus mechanisms to maintain ledger consistency, and facilitates fast, low-cost global fund movement.
Key cryptocurrencies include:
- Bitcoin (BTC): The first widely adopted cryptocurrency launched in 2009 by Satoshi Nakamoto. Positioned as "digital gold" for value storage and payments.
- Ethereum (ETH): The second-largest crypto asset that powers smart contracts, NFTs, DeFi, and Web3 applications.
- Next-gen projects: Like Litecoin and Solana that optimize speed, fees, scalability, and privacy for real-world adoption.
