What is Ethereum? 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.
Ethereum enables developers to build and deploy decentralized applications. A decentralized application or Dapp serves some particular purpose to its users. Bitcoin, for example, is a Dapp that provides its users with a peer to peer electronic cash system that enables online Bitcoin payments.
