Quantum-Safe

BLAKE3 hashing is resistant to quantum computing attacks, future-proofing your proof.

Private

Your files never leave your device. Only the hash is sent to our servers.

Timestamped

Secure blockchain anchoring provides an immutable timestamp for your work.

Verifiable

Anyone can verify your certificate using our public verification tool.

How It Works

  1. Upload your file - Your file is hashed locally using the quantum-safe BLAKE3 algorithm.
  2. Create proof - The hash is stored in our database with a secure timestamp.
  3. Download certificate - Receive a PDF certificate with all the details needed to verify your proof.
  4. Verify anytime - Anyone can verify your certificate using our public verification tool.
