The problem Flag Me Daddy solves

Dating apps today show you profiles — but not reputations.
Looks and bios can be crafted perfectly, but real-life behavior stays hidden.

With Flag Me Daddy, users can:
• Verify dating reputations before matching, not after.
• Share past dating experiences anonymously, without fear of backlash.
• Spot red flags early through trust signals and reviews.

This makes dating:
• Easier – less wasted time on mismatched or unsafe connections.
• Safer – transparency encourages accountability.
• Smarter – every click is backed by verified behavior, not just curated photos.

Challenges we ran into

Preventing Users from Seeing Their Own Reviews

The issue: We needed a way to make sure no one could view reviews written about themselves while still allowing other potential matches to see them.

The solution: We used Oasis Sapphire’s confidential smart contracts to block self-queries and encrypt feedback data, ensuring users cannot access their own reviews while keeping them visible to others.

Balancing Privacy with Verification

The issue: How to confirm reviews are genuine without exposing the reviewer’s identity.

The solution: Integrated wallet-based verification so each review is tied to a verified match, but all reviewer information is encrypted and stored privately on Oasis.
