A sybil-resistant, privacy-preserving prediction market protocol powered by Chainlink CRE and World ID.
🏆 Built for Convergence: A Chainlink Hackathon
Mirage Market is a prediction market protocol where positions are hidden, identities are verified, and settlements are automated.
The Problem: Existing prediction markets expose user positions publicly, enabling front-running, social pressure, and privacy violations. Most markets also rely on centralized resolution oracles that can be manipulated.
Our Solution:
- Privacy-Preserving Commitments — Users commit positions as encrypted hashes (commit-reveal scheme). Amounts and choices remain hidden until settlement.
- Sybil Resistance — World ID verification via Chainlink CRE ensures one-person-one-vote without exposing personal data on-chain.
- Automated AI Settlement — When a market closes, a CRE workflow fetches real-world data via Confidential HTTP, resolves the outcome deterministically, and writes the settlement on-chain — no human oracle needed.
