Ethereum is a decentralized platform for building smart contracts and decentralized applications. It has its own cryptocurrency, Ether, and enables users to transact and communicate without the need for a central authority. In contrast to Bitcoin, Ethereum is a general purpose blockchain that can be programmed for a wide range of tasks. It can be used for building apps and organizations, holding assets, and facilitating financial transactions while respecting user privacy and avoiding censorship. ETH, the native cryptocurrency of Ethereum, is used to fuel and secure the network, serve as collateral for the creation of other tokens, and support the Ethereum financial system. It has value as a means of paying transaction fees and as a store of value or tool for decentralized finance. ETH has initially gained recognition through initial coin offerings (ICOs).
