Zero-Knowledge Proofs for DeFi Reputation: How We Built It
· 4 min read
When we set out to build a reputation layer for DeFi, we hit a fundamental tension: protocols need to verify creditworthiness, but users shouldn't have to broadcast their exact scores to the world. Zero-knowledge proofs solve this elegantly.
This post walks through how CrowdProof uses Groth16 SNARKs to enable private reputation verification — the tradeoffs we considered, the circuit design, and the performance characteristics.
