Demo and sample apps

Live demo

Three sample applications share one hosted Quorum instance. Each has a profile switcher in the navigation bar, so you can create a request as a maker and then switch to a reviewer to approve or reject it.

App	Tech	Scenario
Banking	Go + html/template	Multi-stage wire transfer approval with webhook callbacks
Expense tracker	Node.js + Express	Single-stage expense approval with status polling
Access portal	Python + Flask	Threshold-based security review (2-of-3 voting)

The demo is reset from time to time, and anything you create there is public.

Run the demo locally

docker compose --profile demo up

This starts everything: PostgreSQL, Quorum with the admin console, the policies each app needs (via scripts/setup.sh), seed data, and all three sample apps on localhost:3001, 3002 and 3003. The console is at localhost:8080/console/, signed in as admin / admin123.

What each app demonstrates

• Banking: a webhook-driven flow on the Go client. Transfers execute automatically when Quorum sends an approved webhook, verified with client.ParseWebhook.
• Expense tracker: a polling-based flow. The detail page fetches the latest status from Quorum on each page load.
• Access portal: threshold voting. Two of three security reviewers must approve, and not every rejection is fatal.

Each app embeds all three Quorum widgets: <quorum-request-list> on the dashboard as an approval queue, <quorum-stage-progress> on detail pages for stage visualisation, and <quorum-approval-panel> for approve and reject actions. Clicking a row in the request list navigates to the matching local detail page.

The source for all three is under examples/ in the repository.

Seed data

Quorum ships with a seed script that populates a fresh instance with sample policies, requests, and approvals:

# Against a running Quorum server
make seed

# Or via Docker Compose
docker compose --profile seed up

The seed script creates:

• 4 policies: Expense Approval, Wire Transfer, System Access, Account Closure
• 6 requests by different makers (alice, bob, charlie, dave, eve, frank)
• Sample approvals: 2 approved, 1 advanced to stage 2, 3 pending
• 1 webhook (httpbin.org for testing)
• Console admin: admin / admin123
