yarn dev

# Open browser
http://localhost:5173/debug

3. Test ZKML Flow

1. Scroll to "ZKML Reputation Verifier"
2. Select proof type: "Exact"
3. Click "Generate ZK Proof"
4. Watch progress (0-100%)
5. Verify circuit caching on second run
6. Test threshold proof type
7. Verify privacy (no attestation data exposed)

🐛 Known Limitations (Local Testing)

Current Setup

✅ Working:

  • Hardhat node running
  • All contracts deployed
  • Circuit artifacts generated
  • Application built
  • Configuration updated

⚠️ Limitations:

  • Dev server needs manual restart to serve properly
  • Mock circuits (not real EZKL-generated proofs)
  • No backend proof server running
  • WebSocket updates not tested

For Production

To move beyond local testing:

  1. Generate Real Circuits:

    python3 Notebooks/EBSL_EZKL.py

  2. Deploy to Testnet:

    export PRIVATE_KEY="0x..."
yarn deploy:sepolia

  3. Start Backend Server:

    cd server
npm run build
npm start

📈 Performance Expectations

Local Testing

Operation Expected Time
Circuit download (first) 2-5s
Circuit cache load <100ms
Proof generation (16) 2-5s
Proof generation (32) 5-15s
Proof generation (64) 15-30s

Memory Usage

Component Peak Memory
Circuit 16 100-150 MB
Circuit 32 150-250 MB
Circuit 64 250-400 MB
