$ETH Ethereum (ETH) is a decentralized blockchain platform that enables the creation and execution of smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum extends beyond Bitcoin’s financial capabilities by allowing programmable contracts without third-party interference. Its native cryptocurrency, Ether (ETH), powers transactions and pays for computational services. Ethereum transitioned to a proof-of-stake consensus model in 2022, significantly reducing energy consumption. It supports a wide ecosystem of decentralized finance (DeFi), NFTs, and Web3 applications. As a cornerstone of blockchain innovation, Ethereum continues to evolve, fostering a more open, secure, and decentralized digital economy.
