Bernstein and notarized deposits
How a blockchain certificate compares to depositing a document with a notary or a national office - and when each one is the right tool
Long before blockchain existed, every jurisdiction built its own way to answer one question - did this document exist on this date, and can I prove it to someone who has reason to doubt me?
France has the enveloppe Soleau, now e-Soleau, filed with the INPI. Germany relies on notarial deposit and the Prioritätsnachweis it produces. Italy works through data certa, established by a qualified timestamp or a deposit with the SIAE. Elsewhere, a notary, a sealed envelope, or a registered letter plays the same role.
These instruments work. They are recognised, understood by the courts, and older than any of us.
They were also designed for a world of single, finished documents - and that is where a blockchain certificate answers a different shape of problem.
What a deposit does well
Stated first, because these are real advantages and no technology removes them
Statutory recognition
A deposit made through a national office or a notary carries a status defined by law. A judge does not have to be persuaded that the mechanism is sound - the legislator already decided.
Institutional familiarity
Every lawyer in the jurisdiction knows the instrument by name and has handled one. Nothing has to be explained before the evidence can be discussed.
A third party holds the content
The office or the notary keeps the document itself, not only a fingerprint of it. If you lose your copy, the deposit still contains the work.
Side by side
| Aspect | Deposit or notarial filing | Bernstein certificate |
|---|---|---|
| What it proves | The deposited content existed on the filing date | The file existed on the anchoring date, unchanged since, under your control |
| Cost structure | Per deposit, plus a fee at every renewal | Per certificate, with no renewal fee ever |
| What you can deposit | Capped by the office's file-size or page limits | Any file of any size - only its fingerprint is published |
| How long it lasts | A fixed term, renewable while you keep paying | Permanent; a public blockchain does not expire |
| Who can verify it | The office or notary that holds the record | Anyone, with open tools, without asking Bernstein |
| Where it counts | Strongest in the jurisdiction that created it | The same proof everywhere the mechanism is understood |
Fees, size caps and deposit terms are set by each office and change over time. Check the current conditions with the institution before comparing costs.
Where a blockchain certificate differs
Not better in every respect - different in four specific ones
Immediate and repeatable
A certificate takes minutes, not an appointment. That changes what you are willing to record - you stop rationing proof to the milestones you can afford.
Nothing is disclosed
Only a cryptographic fingerprint is published. The file never leaves your control, and no third party - including us - can read it. For a trade secret, disclosure to a custodian is itself a risk.
No expiry, no renewal
A deposit lapses when you stop renewing it, often at the exact moment you had forgotten about the file and most need the proof. A blockchain anchor has no term.
Verifiable without us
The proof does not depend on Bernstein continuing to exist. Anyone can recompute the hash and find it in the blockchain with open-source tools.
The case a per-document deposit cannot answer
A deposit captures one finished document. Real innovation does not arrive that way:
Depositing each of these separately is not affordable, so in practice nobody does it - and the record has a hole exactly where the dispute later lands. A certificate that costs the same whether you create one or a hundred removes that constraint.
Most of the time, the answer is both
The question is not which instrument wins. It is which parts of your work currently have no dated record at all.
What Bernstein is, and is not
Bernstein is a private certification service. We are not a notary, a national intellectual property office, or a collecting society, and we issue no public instrument. A Bernstein certificate is evidence, not a title, and confers no right by itself. Each certificate also carries a qualified electronic timestamp under eIDAS, alongside the Bitcoin anchor.
