Ethereum is a decentralized, open-source blockchain platform that enables the creation of smart contracts and decentralized applications (dApps). Launched in 2015, it revolutionized blockchain technology by allowing developers to build on its network beyond simple cryptocurrency transactions. Ethereum powers much of the decentralized finance (DeFi) ecosystem, enabling peer-to-peer lending, trading, and investing without traditional intermediaries. With the transition to Ethereum 2.0 and proof-of-stake, it has improved scalability and energy efficiency. As the foundation for NFTs, DeFi, and Web3 applications, Ethereum continues to play a critical role in shaping the future of digital finance and online ecosystems.
