#EthereumFuture Ethereum (ETH) is the second-largest cryptocurrency by market cap, known for its smart contract functionality and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin, Ethereum enables developers to build decentralized platforms, DeFi projects, and NFTs. Its native token, Ether (ETH), fuels transactions and computational services on the network. Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in 2022 (the Merge), improving scalability and reducing energy consumption. Despite competition from newer blockchains, Ethereum remains a leader in innovation, with ongoing upgrades (like Dencun) to enhance speed and reduce fees. ETH is widely traded and held as both a utility and investment asset.
