Guest registration example

General design

This live event / hospitality sample application registers guests, online or at a desk, then let them checkin at a gate. The guest needs to checkout before unregistering.

In the blockchain DB, the user name is the key, the value of wich is either:

• registered if the user is present in the DB but has not physically passed the gate
• checked in if the user entered the event

The guest registration live demo page is on chainorchestra.net.

Desk operations

Blockchain users with DeskClerk permissions manage the register / unregister operations.

Sample Node-RED gateway flows

Copy the json samples in the flows folder to the ~/.node-red/lib/flows/ folder on your Node-RED gateway, then import them on the Node-RED web interface using the Import -> Library menu.

The flow samples are documented with the ChainOrchestra flow nodes.
