$ETH Ethereum (ETH) is a decentralized blockchain platform launched in 2015 by Vitalik Buterin. It enables smart contracts and decentralized applications (dApps) without intermediaries. Unlike Bitcoin, which primarily serves as digital gold, Ethereum offers a programmable network where developers can build applications using its native currency, Ether (ETH). Ethereum transitioned to a Proof-of-Stake (PoS) model with the Ethereum 2.0 upgrade, improving scalability, security, and energy efficiency. It plays a crucial role in decentralized finance (DeFi), non-fungible tokens (NFTs), and Web3 innovations. As one of the most influential blockchain ecosystems, Ethereum continues to shape the future of digital finance and technology.
