You can think of Ethereum as a programmable blockchain. Unlike the Bitcoin blockchain which gives predefined operations that are limited to bitcoin transactions only, Ethereum allows users to create their own customized operations or tasks they need to establish. In other words, Ethereum is an open software based on blockchain technology that enables developers to build and deploy decentralized applications that include but are not limited to cryptocurrencies. It ensures that the “customized operations” or “smart contracts” are replicated and processed to all computer networks.
