Happy to hear you like the idea! 🙌🏻🍻 Just a follow up note. The gamification features mentioned (achievements, rewards, venue discovery) require careful balance between public visibility and user privacy. While you can implement basic public anonymous achievements now, meaningful social features need Nostr's upcoming trust circle protocol to:

Let users share specific venue visits with trusted friends only

Enable private recommendations within friend groups

Create meaningful social engagement without exposing user patterns

Balance public badges/achievements with private transaction data

Recommendation: Start with anonymous public achievements, but design your architecture to easily integrate trust circle features once the Nostr protocol adds these capabilities. This ensures you protect user privacy while building toward fuller social features.

Current scope: Anonymous public achievements

Future scope: Rich social features within trust circles
