PredScore
CategoryReputation-Based Prediction Market
Year2025
A reputation-based prediction market on Solana where a user's on-chain reputation matters as much as their money, with a reputation-insurance mechanic.
The Problem
Prediction markets reward money, not accuracy. PredScore adds reputation and an insurance mechanic so users are encouraged to make accurate, thoughtful predictions.
What I Built
As full-stack developer, I built:
- React Native + Expo + TypeScript mobile app
- Solana wallet auth and integration with the FairScale scoring API
- The reputation-risk and trust-based insurance pricing logic
- Market, portfolio, and reputation screens
The Hard Part
Designing the reputation-insurance mechanic so it actually incentivizes accuracy.
