$ETH $ETH Ethereum (ETH) is a decentralized, open-source blockchain platform known for its smart contract functionality. It was proposed by Vitalik Buterin in 2013 and launched in 2015. Ethereum enables developers to build and deploy decentralized applications (dApps) without relying on centralized servers. Its native cryptocurrency, Ether (ETH), is used to power transactions and compensate participants who maintain the network. Ethereum transitioned to a proof-of-stake consensus model with the Merge in 2022, improving energy efficiency. It’s a cornerstone of the decentralized finance (DeFi) and non-fungible token (NFT) ecosystems, making it one of the most influential blockchain platforms globally.
