$ETH Ethereum (ETH) is a leading cryptocurrency and blockchain platform launched in 2015 by Vitalik Buterin. It enables smart contracts and decentralized applications (dApps) to be built and operated without downtime, fraud, or control from a central authority. Ethereum introduced the concept of programmable blockchain, making it much more versatile than Bitcoin. With the transition to Ethereum 2.0, the network now uses proof-of-stake, offering better energy efficiency and scalability. ETH is widely used for decentralized finance (DeFi), NFTs, and Web3 projects. As blockchain technology evolves, Ethereum continues to play a central role in driving innovation and adoption across industries worldwide.
