Hello Blockchain Sample Application for Azure Blockchain Workbench¶
Overview¶
The Hello Blockchain application expresses a workflow between a person sending a request and a person responding to the request. The state transition diagram below shows the interactions between the states in this workflow.
Application Roles¶
| Name | Description |
|---|---|
| Requestor | The party that initiates the "Hello blockchain!" request |
| Responder | The party that responds to the Requestor |
States¶
| Name | Description |
|---|---|
| Request | The state that occurs when a request has been made. |
| Respond | The state that occurs after a response has been made to the request. |
Workflow Details¶

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.
