$ETH Ethereum (ETH) is a leading blockchain platform that enables decentralized applications (dApps) and smart contracts. As the second-largest cryptocurrency by market cap, Ethereum’s native token, Ether, fuels transactions and computational services on its network. Its upgrade to Ethereum 2.0 transitioned it from energy-intensive proof-of-work (PoW) to a more scalable, eco-friendly proof-of-stake (PoS) consensus mechanism. Ethereum’s versatility supports DeFi, NFTs, and enterprise solutions, making it a cornerstone of Web3 innovation. However, challenges like high gas fees and competition from rival blockchains persist. Despite this, Ethereum remains a dominant force in crypto, with ongoing developments aiming to enhance speed, security, and decentralization.
