Cryptocurrency, rooted in blockchain technology, has disrupted traditional financial systems. Bitcoin, Ethereum, and other cryptocurrencies offer decentralized and secure methods of transferring value. Beyond just digital currencies, the underlying blockchain technology has found applications in various industries, ensuring transparent and tamper-proof transactions. Smart contracts, built on blockchain platforms, automate and enforce contractual agreements without the need for intermediaries. Cryptocurrency and blockchain continue to evolve, exploring new avenues such as decentralized finance (DeFi) and non-fungible tokens (NFTs).
