Introduction to Cryptocurrencies
Cryptocurrencies, often referred to as altcoins or competing coins, are digital currencies that operate independently of central banks. While Bitcoin remains the most well-known cryptocurrency, over 800 alternative cryptocurrencies currently circulate in the market.
Between February and April 2017, altcoins' combined market share grew from 15% to nearly 40% of the total cryptocurrency market capitalization. This demonstrates the rapid expansion and diversification of the cryptocurrency ecosystem.
How Cryptocurrencies Work
Blockchain technology serves as the foundation for most cryptocurrencies. This distributed database system, first conceptualized by Satoshi Nakamoto in 2008, creates a peer-to-peer network that securely records and verifies transactions without centralized control.
Key blockchain innovations include:
- Proof-of-work and proof-of-stake algorithms
- Smart contract platforms like Ethereum
- Tokenization of assets for shared economies
- Decentralized applications (DApps)
