PROXAE

Use case

Protect creative work before publishing

To protect a creation before publishing, it is essential to prove its priority. A timestamping service like Proxae certifies that content existed at a given date, without publishing it.

About to publish a work? Before sharing it, create dated proof of its existence. In case of copying or dispute, you will be able to prove you are the original author.

The risk

As soon as you publish online, your creation can be copied, captured, or claimed by someone else. Without prior dated proof, proving you were first is extremely difficult.

Real-world protection cases

▸

A freelancer sends a mockup to a client — they certify it first to prove authorship, in case of non-payment or unauthorized reuse.

▸

A startup shares a pitch deck with investors — the timestamp proves the concept existed before the meeting.

▸

An author sends a manuscript to a publisher — the certification proves authorship if the text is copied or used without consent.

The Proxae solution

1

Certify before publishing

Upload your file (image, PDF, audio, video, text). The SHA-256 fingerprint is computed locally.

2

Certain date in Bitcoin

The fingerprint is anchored in a Bitcoin block. No one can dispute this date.

3

Publish with confidence

You now have irrefutable proof that your work existed before its publication. If copied, you have prior art.

Before sharing your creation, take 10 seconds to certify it. It's free and it can change everything.

Frequently asked questions

Does this replace copyright?
No. Copyright arises automatically upon creation. Proxae provides proof of date — an essential element to demonstrate prior art in case of dispute.
What creative formats are supported?
All file formats: images (PNG, JPG, PSD), audio (MP3, WAV, FLAC), video (MP4, MOV), documents (PDF, DOCX), and many more.
Can I certify multiple versions?
Yes. Each version generates a different hash and therefore a separate proof. This is ideal for tracking the evolution of a creative project.
Is it recognized in court?
Blockchain timestamping is admissible evidence. The RFC 3161 certificate (Pro plan) complies with eIDAS and is recognized in the EU. In case of dispute, it is a strong argument for proving priority.
What is the difference with copyright?
Copyright arises automatically upon creation, but is difficult to prove without a certified date. Proxae provides that proof of date — an essential complement to copyright.
