What Is Ethereum (ETH)?
Ethereum is a foundational blockchain platform that enables the creation of decentralized applications (dApps) through self-executing smart contracts. Its native cryptocurrency, ETH, powers transactions and network fees. By introducing programmability, Ethereum expanded blockchain use far beyond payments, giving rise to major ecosystems in DeFi, NFTs, and DAOs. Its transition to Proof of Stake (The Merge) drastically improved efficiency. Despite challenges like scalability and volatility, Ethereum's first-mover advantage, robust developer community, and continuous innovation keep it at the forefront of the Web3 revolution.
