Workflow Details

state diagram of workflow

An instance of the Hello Blockchain application's workflow starts in the Request state when a Requestor makes a request. The instance transitions to the Respond state when a Responder sends a response. The instance transitions back again to the Request state when the Requestor makes another request. These transitions continue for as long as a Requestor sends a request and a Responder sends a response.
