The app all came together code-wise in about a week, but was built from months of different connections all coming together at once. It was (as far as I know) the first time three important technologies were paired with ZK:

  2. NFC (Disk from IYK used to create a group at an in-person event)
  3. ZK-anon Discord question bot (used for questions during the presentation)

Attached is the slideshow used at the MIT ZK IAP course final presentations:
