Peer Badge Nominations

Overview​

After attending an event, members can nominate fellow participants for recognition badges. When a participant receives 3 or more nominations for the same badge type from different nominators within 7 days of the event, the badge is automatically awarded.

MOST_HELPFULHelped others at the event
BEST_SPIRITBest attitude and sportsmanship
(additional types may be configured)

Step-by-Step: Nominate a Peer​

  1. Navigate to a FINISHED event you attended.
  2. Click "Nominate a Peer" button.
  3. The NominatePeerBadgeDialog opens.
  4. Select a participant from the event.
  5. Select the badge type you want to nominate them for.
  6. Click "Submit Nomination".
  7. Your nomination is recorded. You cannot nominate the same person for the same badge at the same event more than once.

Award Process (Automatic)​

The PeerBadgeAwardScheduler runs every hour:

  1. Scans FINISHED events from the past 30 days that haven't been processed yet.
  2. Counts nominations: GROUP BY recipientId, badgeType HAVING COUNT(DISTINCT nominatorId) >= 3.
  3. For qualifying recipients: awards the badge and sends a push notification.
  4. Marks the event as processed to prevent double-awarding.

Security Notes​

  • Only authenticated members with an ACCEPTED application for the event can nominate.
  • Nominations are immutable — cannot be withdrawn after submission.
  • The award threshold (≥3 nominators) prevents one person from gaming the system.
  • A member cannot nominate themselves.

QA Checklist​

  • Nominate peer at FINISHED event → nomination recorded (201)
  • Nominate same peer again → 409 Conflict (already nominated)
  • 3 different members nominate same peer for same badge → badge awarded within 1 hour
