CrowdProof Documentation

CrowdProof is a decentralized credit bureau for Web3. We generate privacy-preserving reputation scores for Ethereum wallets using machine learning and zero-knowledge proofs.

What CrowdProof Does​

  • Reputation Scoring — Analyzes on-chain activity across 6+ DeFi protocols to generate scores in 8 categories (0–1000 scale)
  • Zero-Knowledge Proofs — Prove your score meets a threshold without revealing the actual number
  • Decentralized Identity — did:ethr identifiers with verifiable credentials
  • Compliance — Privacy-preserving age verification and KYC for regulated industries
  • Dispute Resolution — On-chain governance for score challenges
