Protect your documents and your intellectual property

Timestamping a document can give you a protection similar to that of a copyright. A copyright is basically the announcement that you were in possession of a document at a certain date. And this claim is usually made by an official state organization.

We leverage the blockchain technology to timestamp your documents, whatever they are PDFs, images, videos... By storing a digital footprint of your file to the BitCoin blockchain, this service gives you a reliable, auditable and independant mean to prove that you had this document at that date. For free.

Why timestamping


Once your document is timestamped, you can prove to anyone that you were owning it at that date.
