PROXAE

Use case

Prove you had the idea first

To prove the priority of an idea, you need to create dated proof before anyone else can claim it. A timestamping service like Proxae certifies that content existed at a given date, without publishing it.

You have an idea, a concept, an innovation? Without dated proof, there is no way to prove you had it first. Proxae creates a timestamped cryptographic fingerprint in the Bitcoin blockchain — in seconds, for free.

The problem

An idea cannot be patented. And without a dated record, anyone can claim ownership of a concept. Traditional methods (Soleau envelope, INPI filing, registered mail) are slow, expensive, or easy to challenge.

Real-world examples

▸

An entrepreneur describes their app concept and certifies it before pitching to investors — proof of priority in case of dispute.

▸

A researcher timestamps hypotheses before submitting to a journal — in case of parallel publication, they can prove they had the idea first.

▸

An inventor certifies prototype plans before contacting a manufacturer — protection against idea theft.

How Proxae solves this

1

Describe your idea

Type your concept in the text field. The SHA-256 fingerprint is computed in your browser — your text is never sent to our servers.

2

Instant Bitcoin timestamp

The fingerprint is anchored in the Bitcoin blockchain via OpenTimestamps. In ~3 hours, your proof is confirmed in an immutable block.

3

Proof verifiable for life

You receive a permanent link and an OTS file. Anyone can verify that your idea existed on that date — even if Proxae disappears.

Have an idea worth protecting? Create a proof of priority in 10 seconds — free, no sign-up required.

Frequently asked questions

Does this protect my idea?
Proxae proves your idea existed at a given date. It is not a patent, but it is strong evidence in a prior art dispute.
Is my idea visible to others?
No. Only the cryptographic fingerprint (hash) is stored. Your text stays in your browser and is never transmitted.
How long does confirmation take?
The timestamp is submitted instantly. Confirmation in a Bitcoin block takes approximately 3 hours.
What is the legal value of blockchain timestamping?
Blockchain timestamping constitutes admissible evidence. With the Pro plan, the RFC 3161 certificate compliant with eIDAS strengthens its probative value. It is not a property title, but solid proof of date.
What is the difference with a patent office filing?
Patent offices protect industrial property (patents, trademarks). Proxae proves that content existed at a given date. Both are complementary — Proxae is instant, free, and confidential.
