$ETH Ethereum ($ETH) is a decentralized blockchain platform that enables smart contracts and decentralized applications (dApps) to run without any downtime, fraud, or interference from third parties. Launched in 2015 by Vitalik Buterin and others, Ethereum introduced the concept of programmable blockchain, allowing developers to build and deploy complex applications beyond just cryptocurrency transactions. ETH, the native token of Ethereum, is used to pay for transaction fees and computational services on the network. With its upcoming upgrades like Ethereum 2.0 and shift to proof-of-stake, Ethereum aims to improve scalability, reduce energy consumption, and support a more efficient and sustainable blockchain ecosystem.
