Ethereum is a worldwide network of interconnected computers (nodes) that enforce, execute and validate programs in a decentralized manner without requiring a server, memory, CPU power, or any other computing function, as it is all provided by thousands of ethereum nodes scattered across the world. In short, ethereum is a global computer.
This global computer allows applications, called Decentralized Apps or DApps, through the use of smart contracts – simple javascript like code – to run exactly as they have been programmed, requiring no permission, having no intermediary, in a largely immutable manner, lacking any downtime, censorship, fraud, or third party interference.
It further ensures the operation of ETH – ethereum’s digital currency which turns money into pure code – opening many new opportunities, including machine to machine payments, one click online commerce, decentralized autonomous organizations as well as completely new business models.
