$ETH Ethereum is a decentralized, open-source blockchain platform renowned for its smart contract functionality. Unlike Bitcoin, which primarily focuses on digital currency, Ethereum enables developers to build and deploy a vast array of decentralized applications (dApps), from DeFi protocols and NFTs to gaming and supply chain management. Its native cryptocurrency, Ether (ETH), fuels transactions and computational services on the network. Ethereum's transition to Proof-of-Stake (The Merge) significantly enhanced its energy efficiency and laid the groundwork for future scalability improvements, making it a foundational layer for Web3 innovation.
