Ethereum $ETH is a leading blockchain platform known for its smart contract functionality and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum goes beyond simple cryptocurrency transactions, enabling developers to build complex programs on its network. ETH is the native cryptocurrency, used to pay for transactions and computational services. With the transition to Ethereum 2.0 and its shift to proof-of-stake, the network has become more energy-efficient and scalable. Ethereum plays a crucial role in DeFi (Decentralized Finance), NFTs (Non-Fungible Tokens), and Web3 innovation. Despite competition and market volatility, ETH remains a cornerstone of the blockchain ecosystem, driving the next generation of decentralized technologies and digital finance.
