Ethereum is a decentralized blockchain platform founded in 2015 by Vitalik Buterin. It's not just a cryptocurrency but also enables smart contracts and distributed applications (DApps) to be built and run without any downtime, fraud, control, or interference from a third party. Ethereum’s native token is Ether (ETH). It goes beyond being merely a digital currency; it's also used to execute smart contracts on the platform. Ethereum has significantly influenced the blockchain industry, especially in the development of financial services and digital collectibles.
