Ethereum is a platform powered by blockchain technology that is best known for its native cryptocurrency—called Ether or ETH or simply Ethereum. The distributed nature of blockchain technology is what makes the Ethereum platform secure, and that security enables ETH to accrue value.
The Ethereum platform supports Ether in addition to a network of decentralized apps, otherwise known as “dApps.” Smart contracts, which originated on the Ethereum platform, are a central component of how the platform operates. Many decentralized finance (DeFi) and other applications use smart contracts in conjunction with blockchain technology.
A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it
