$ETH ETH, or Ethereum, is a decentralized blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum revolutionized blockchain technology by introducing programmability, allowing for more complex functionalities beyond simple transactions. Its native cryptocurrency, Ether (ETH), is used to pay transaction fees and computational costs on the network.

Ethereum operates on a global network of nodes, ensuring security and decentralization. It transitioned to a proof-of-stake (PoS) consensus mechanism in 2022 with the Ethereum Merge, significantly reducing its energy consumption and increasing scalability. This change also paved the way for future upgrades to improve speed and reduce costs.

Ethereum has fueled innovation in various fields, including finance (DeFi), art (NFTs), and supply chain management. Its ability to support decentralized systems has positioned it as a cornerstone of Web3 and the broader blockchain ecosystem.
