$ETH Ethereum (ETH) is a leading blockchain platform launched in 2015 by Vitalik Buterin. Unlike Bitcoin, which focuses on digital currency, Ethereum enables smart contracts—self-executing programs that run on its decentralized network. This functionality supports decentralized applications (dApps), powering innovations in finance (DeFi), digital art (NFTs), and more. Ethereum recently transitioned to a proof-of-stake consensus mechanism, reducing energy use by over 99%. Its native token, ETH, is used for transaction fees and as a store of value. As the backbone of Web3 development, Ethereum remains a driving force in reshaping the digital economy and pushing the boundaries of blockchain technology.
