- Mining and Proof-of-Work (PoW): A process used by Bitcoin and other cryptocurrencies to validate transactions and secure the network.
- Proof-of-Stake (PoS): An alternative consensus mechanism where validators are chosen based on the number of coins they hold and stake.
- Wallets: Digital storage systems that allow users to store and manage their cryptocurrencies securely.
Popular Cryptocurrencies
While Bitcoin remains the most recognized, several other cryptocurrencies have gained significant attention, including:
- Ethereum (ETH): Known for its smart contract functionality.
- Binance Coin (BNB): Used within the Binance ecosystem.
- Cardano (ADA): Focuses on sustainability and scalability.
- Ripple (XRP): Aims to facilitate fast and low-cost international transactions.
- Solana (SOL): Designed for high-speed and low-cost transactions.
