Timestamp Document

What is Digital Time-stamping?

Digital Time Stamping is a way to make your document independently verifiable. All documents are anchored to a public blockchain to make sure that the document is tamper-proof and can be verified by uploading it to the Twala website/dashboard or your own website (via an API request). Documents can also be verified by scanning the QR code that is included in the final document.

Use Cases

If you have multiple numbers of certificates (attendance/participation/School/office/training), just bulk upload it to the system, together with the name and email addresses of the recipients. Once sent, the recipients will receive their digitally timestamped certificate via email.
If you have developed an application that generates a document that you need to secure to make sure it is verifiable and tamper-proof. For example, an application that generates verifiable receipts, an application that generates a verifiable medical prescription, or an application that generates verifiable students grades/records.
