$ETH

Ethereum (ETH) is a decentralized, open-source blockchain system that features smart contract functionality. Launched in 2015 by Vitalik Buterin and others, it enables developers to build decentralized applications (dApps) across various industries. Unlike Bitcoin, which primarily serves as digital currency, Ethereum's blockchain is programmable, allowing for more complex, autonomous agreements through smart contracts. Ether is the platform’s native cryptocurrency, used to pay for transactions and computational services. Ethereum is transitioning from proof-of-work (PoW) to proof-of-stake (PoS), significantly reducing its energy consumption. This evolution supports scalability and sustainability. Ethereum continues to be a leader in decentralized finance (DeFi) and NFT ecosystems worldwide.
