Ethereum $ETH is more than just a cryptocurrency—it's a powerful, decentralized platform enabling smart contracts and decentralized applications (dApps) to run without downtime, fraud, or third-party interference. Launched in 2015 by Vitalik Buterin, Ethereum introduced the concept of programmable blockchain, allowing developers to build a range of financial services, games, and digital assets directly on-chain. Its recent transition to Ethereum 2.0, using Proof of Stake, significantly reduced its energy consumption while improving scalability and security. ETH, the native token, is used to power transactions, reward validators, and fuel innovation across DeFi, NFTs, and Web3 projects. As the backbone of the decentralized internet, Ethereum continues to shape the future of finance, technology, and digital ownership.
