$ETH Ether (ETH) is the native cryptocurrency of the Ethereum blockchain, the world's second-largest by market capitalization after Bitcoin. Unlike Bitcoin, Ethereum is more than just a digital currency; it's a decentralized platform enabling "smart contracts" and decentralized applications (dApps).

ETH fuels the Ethereum network, acting as "gas" to pay for transaction fees and computational services. Developers use ETH to build and run applications. Since its launch in 2015, Ethereum has transitioned to a Proof-of-Stake (PoS) consensus mechanism, making it more energy-efficient. ETH is a popular investment asset and can be used for various purposes within the ever-expanding Web3, DeFi, and NFT ecosystems.
