$ETH Ethereum (ETH) is a decentralized, open-source blockchain platform that revolutionized the digital world by introducing smart contracts. Launched in 2015 by Vitalik Buterin, Ethereum enables developers to build and deploy decentralized applications (dApps) and create programmable, self-executing agreements. Its native cryptocurrency, Ether (ETH), fuels transactions and operations on the network. Ethereum's versatility has made it a cornerstone of decentralized finance (DeFi), non-fungible tokens (NFTs), and Web3 innovations. With the transition to Ethereum 2.0, the network is shifting from energy-intensive proof-of-work (PoW) to eco-friendly proof-of-stake (PoS), enhancing scalability, security, and sustainability. Ethereum remains a driving force in blockchain technology and the future of decentralized ecosystems.
