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.
