Ethernet nodes. The "Distributed Platform" section means that anyone can build and run ethereum nodes just as anyone can run a bitcoin node. Anyone who wants to run a "smart contract" on a node must pay to the operators of those nodes in ether, a crypto currency associated with Ethereum. As a result, the person running the Ethernet node provides the computing power and is paid in Ethernet, which is similar to the ability of the person running the bitcoin node to hash and pay in Bitcoin. In othe
