Wrangler — Anonymous ZK Feedback
A decentralized app on the Midnight Network for anonymous, Zero-Knowledge-verified feedback — submit with proof you're authorized, without revealing who you are.
01Challenge
Collecting sensitive feedback usually means trusting a middleman with your identity. Government and enterprise surveys need real, verifiable participation — but voters won't open up if their answer can be tied back to them.
02Strategy
Built a Midnight Network (Level 3: Half Moon) dApp in TypeScript/Compact. Feedback is submitted with a Zero-Knowledge proof that the sender holds a valid credential — the ledger verifies authorization, records the message, and learns nothing about who wrote it. Contract deployed on Midnight Preview with a dashboard for on-chain inspection.
