#IsraelIranConflict Ethereum is a decentralized, open-source blockchain platform that enables smart contracts and decentralized applications (dApps) to run without any downtime, fraud, or interference. Launched in 2015 by Vitalik Buterin and others, Ethereum goes beyond simple transactions by allowing developers to create complex programs on its blockchain. Its native cryptocurrency, Ether (ETH), is used to pay for transactions and computational services. Ethereum is also transitioning to a more energy-efficient model through Ethereum 2.0, which uses a proof-of-stake mechanism. This evolution aims to improve scalability, security, and sustainability, making Ethereum a key player in the world of decentralized finance (DeFi) and NFTs.
