This proof lives on a public blockchain and does not depend on IPWeb3 staying online.
- Compute the SHA-256 of your original file.
- Confirm it matches the File SHA-256 shown above.
- Open this transaction on any Polygon explorer (for example polygonscan.com) using the Transaction value above. Confirm the same hash and the registration date.
- 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.
