Ethereum (ETH) is a decentralized blockchain platform that enables smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin, it introduced programmability to blockchain through its Ethereum Virtual Machine (EVM). ETH, the native cryptocurrency, is used to pay for transactions and computational services. Ethereum transitioned to a proof-of-stake consensus mechanism in 2022 (Ethereum 2.0), enhancing energy efficiency and scalability. It is widely used in DeFi, NFTs, and Web3 ecosystems. As one of the most influential blockchain networks, Ethereum continues to evolve through upgrades aimed at improving speed, cost-efficiency, and security.
