$ETH Ethereum (ETH) is a decentralized, open-source blockchain system that features smart contract functionality. Created by Vitalik Buterin in 2015, Ethereum enables developers to build decentralized applications (dApps) and deploy autonomous smart contracts, revolutionizing the digital space. Its native cryptocurrency, Ether (ETH), is used for transactions, gas fees, and staking in Ethereum’s proof-of-stake consensus. Unlike Bitcoin, Ethereum supports programmability, making it a foundational platform for NFTs, DeFi, and DAOs. With Ethereum 2.0 upgrades, it aims to scale efficiently while reducing environmental impact. ETH is more than a currency—it's a key to a decentralized future, empowering users worldwide through innovation and transparency.
