Ethereum is more effective than pure cryptocurrency. Through Ethereum, users can create any decentralized application (i.e. DApp) and smart contract. Theoretically, programmable Ethereum can be used for any economic or governance activities.
In short, Ethereum is similar to the blockchain version of Android and iOS systems, a blockchain APP platform. Ethereum is a global open source platform for decentralized applications (DApp). The name comes from Ether and the suffix ruem (Greek meaning is "oil")
Since it was introduced to the world in 2008, blockchain has become an increasingly popular buzzword among businesses across a wide range of industries.
