$ETH Ethereum ($ETH) is a decentralized blockchain platform known for its smart contract functionality. Launched in 2015 by Vitalik Buterin, it enables developers to create decentralized applications (dApps) without relying on traditional intermediaries. Unlike Bitcoin, which primarily serves as digital gold, Ethereum’s programmable blockchain supports DeFi, NFTs, and enterprise solutions. The network transitioned to Ethereum 2.0 with a proof-of-stake consensus, improving scalability and reducing energy consumption. $ETH remains a leading cryptocurrency, widely used for transactions, staking, and governance in decentralized ecosystems. However, challenges like high gas fees and regulatory scrutiny continue to shape its adoption and future development.
