PolkadotJS / Edgeware Node User Rating App

A user rating application using the PolkadotJS API and the Edgeware Substrate Node.

Users can rate rate another user only once and cannot change rating and also see ratings of other users.

This is a technical Assessment project. This solution uses Node.js runtime, React.js for the UI, with Styled Components for styling, Polkadot-JS API easy-to-use wrappers around JSONRPC calls that flow from an application to a node.
