Register your work today. Prove tomorrow that it already existed.

Upload a file and within a minute you have a dated certificate, a public link anyone can check, and an entry in the Bitcoin blockchain that keeps its value even if Veritas disappears.

The tool itself is currently in Spanish — the proof it produces is language-neutral.

The uncomfortable question

What this proves, and what it does not

It does prove

That a file with exactly this content existed at a specific moment, and that it has not changed by a single bit since. That part is mathematics and an independent time authority, not our word.

It does not prove

That you are the author. Anyone can timestamp a file they did not make. What priority gives you is the stronger position in a dispute: whoever can show the earlier sealed date has the better evidence, not the final word.

Chain of evidence

Four links, none of which requires trusting us

Each one is checkable on its own, by someone who has never heard of Veritas.

You upload

The file never leaves your control longer than it takes to hash and scan it.

We quarantine

Antivirus and format checks run before anything is written to the record.

We timestamp

A SHA-256 fingerprint is sealed by an external RFC 3161 time authority and signed.

We anchor

The fingerprint enters an append-only Merkle log and is anchored to Bitcoin.

Verify it without us

The proof does not live on our servers

The Bitcoin anchor is public and permanent. The RFC 3161 seal comes from a time authority that is not us. If this company shut down tomorrow, every certificate already issued would still be verifiable — that is the point of anchoring it somewhere we do not control.

Who it is for

One seal, four jobs

AI agents

An agent can verify without asking you

Verification is an open, unauthenticated endpoint, and there is an MCP server with a small set of scoped tools. An assistant can confirm that a file is sealed and when — with a person still in the loop for anything that writes.

It costs nothing to find out

No account, no card, no trial that expires. Seal one file and look at what comes back.
