$ETH Ethereum (ETH) is the native cryptocurrency of the Ethereum blockchain, a decentralized platform that supports smart contracts and decentralized applications (dApps). Unlike Bitcoin, Ethereum allows developers to create programmable agreements that execute automatically when conditions are met. ETH is used to pay for transaction fees and computational services on the network, often referred to as "gas." Following its upgrade to Ethereum 2.0, the network now uses a Proof of Stake (PoS) consensus mechanism, enhancing security and reducing energy consumption. ETH plays a vital role in powering decentralized finance (DeFi), NFTs, gaming, and the broader Web3 ecosystem, promoting innovation worldwide.
