$ETH Ethereum (ETH) is a decentralized blockchain platform that enables smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum introduced programmability to blockchain technology, allowing developers to create a wide range of applications beyond simple transactions. ETH, the native cryptocurrency, is used to pay for transaction fees and computational services on the network. With the transition to Ethereum 2.0 and Proof of Stake, the network aims to be more energy-efficient and scalable. Ethereum plays a foundational role in DeFi, NFTs, and Web3, powering much of the innovation in the blockchain and crypto ecosystem.
