Signature Verification

Verify signatures without revealing private key

Difficulty: Advanced
Time: ~30 seconds
Privacy: 100% Shielded

Generate Proof

Your private key will never be shared

Tip: This circuit verifies your digital signature without revealing the private key. Uses EdDSA-Poseidon algorithm.

How It Works

  1. 1Provide private key (kept secret)
  2. 2Enter message to sign
  3. 3Add random nonce
  4. 4System generates signature proof
  5. 5Verify without exposing key

Use Cases

✓
Message authentication
✓
Digital signatures
✓
Transaction signing
✓
Identity verification
