$ETH Ethereum (ETH) is a decentralized, open-source blockchain platform known for its smart contract functionality. Launched in 2015 by Vitalik Buterin and others, it enables developers to build and deploy decentralized applications (dApps) without relying on centralized entities. Ether (ETH), the platform’s native cryptocurrency, is used to pay for transaction fees and computational services. Ethereum is a key player in the world of decentralized finance (DeFi), non-fungible tokens (NFTs), and Web3 innovations. With the transition to Ethereum 2.0 and proof-of-stake, it aims to become more scalable, secure, and energy-efficient, solidifying its role in the future of blockchain technology.
