$ETH (ETH) is a leading decentralized blockchain platform that enables smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin, it goes beyond Bitcoin by allowing developers to build programmable, trustless systems without intermediaries. Ether (ETH) is the platform’s native cryptocurrency, used to pay for transactions and computational services. Ethereum transitioned to a proof-of-stake consensus mechanism in 2022 via the "Merge," significantly reducing its energy consumption. Its robust ecosystem supports DeFi, NFTs, and Web3 innovations, making it a cornerstone of blockchain technology. Ethereum continues to evolve, aiming to improve scalability, security, and sustainability through ongoing upgrades.
