$ETH Ethereum (ETH) is a decentralized, open-source blockchain platform that enables the creation and execution of smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum goes beyond Bitcoin’s basic functionality by offering a flexible, programmable framework. Its native cryptocurrency, Ether (ETH), is used to pay for transactions, computational services, and as a store of value. Ethereum introduced the concept of a “world computer,” where code runs transparently without central control. It transitioned from proof-of-work to proof-of-stake in 2022 through an upgrade known as “The Merge,” significantly reducing energy consumption. Ethereum powers a wide range of innovations, including decentralized finance (DeFi), non-fungible tokens (NFTs), and blockchain-based games. Despite scalability challenges and high gas fees, ongoing upgrades like “sharding” aim to enhance efficiency. Ethereum remains a leading platform in the blockchain ecosystem, driving the development of Web3 and decentralized internet infrastructure.
