Verify this certificate yourself, forever

This proof lives on a public blockchain and does not depend on IPWeb3 staying online.

  1. Compute the SHA-256 of your original file.
  2. Confirm it matches the File SHA-256 shown above.
  3. Open this transaction on any Polygon explorer (for example polygonscan.com) using the Transaction value above. Confirm the same hash and the registration date.
  4. If the values match, the proof is valid, even if IPWeb3 no longer exists.

Computing a SHA-256 is free and built into every computer. macOS or Linux: shasum -a 256 yourfile. Windows: certutil -hashfile yourfile SHA256.
