Cryptocurrency
Cryptocurrency is a digital or virtual form of currency that uses cryptography for security and operates on decentralized networks based on blockchain technology. It enables peer-to-peer transactions without the need for intermediaries like banks, providing transparency, immutability, and often anonymity. Examples include Bitcoin, Ethereum, and many altcoins designed for various financial and technological applications.
Developers should learn about cryptocurrency to build decentralized applications (dApps), smart contracts, and blockchain-based solutions, which are increasingly used in finance, supply chain, and digital identity systems. Understanding cryptocurrency is essential for roles in fintech, blockchain development, and cybersecurity, as it underpins innovations like DeFi (Decentralized Finance) and NFTs (Non-Fungible Tokens).
