A product that promises your documents are verifiable must itself be verifiable. These numbers aren't ours: they're on the public Bitcoin chain and anyone can check them.
Download any document's proof, install the official OpenTimestamps client and run ots verify. The answer comes from Bitcoin, not from this site.
If CODEX disappeared tomorrow, your proofs would still be valid: they live inside the file and on a chain nobody controls.

BIOMAG S.L.U., a manufacturer from Vitoria-Gasteiz with its own brands —Mars Gaming, Tacens, Anima— selling in eight European countries. We are not a startup: we're a company with years of clients who dispute, suppliers who deny orders and distributors who argue invoices. CODEX comes from that problem, not from a pitch deck.
You can check: the tax ID is in the footer, the brands are in the shops, and the company existed before this website did.
A firm keeps its records for six years under the Commercial Code, ten under anti-money-laundering rules, five for client files. The question isn't whether your provider will still be around: it's whether your proof will still hold.
Ours will. The fingerprint is on the Bitcoin chain and the proof travels inside the PDF you download. Keep it where you keep the rest of your archive: it will still check out with or without us, and without paying anything.
From 24 December 2027, the regulated private sector will have to accept the EU identity wallet (eIDAS 2.0). That changes how people are identified, not how you prove a document hasn't changed.
Your seal will still be the same hash on the same chain. Whatever comes in identity will sit on top; it doesn't replace what is already anchored. And we won't promise wallet integration until it exists and we've tested it: we'd rather put it that way.
Worth stating precisely. Article 326.4 of the Spanish Civil Procedure Act grants a presumption of authenticity to documents that used a QUALIFIED trust service, from the official list under Regulation (EU) 910/2014. CODEX is not a qualified service, and a public chain such as Bitcoin cannot be one: that list is an administrative register, not a property of cryptography.
What that means in practice: with a qualified service, whoever challenges the document must show the evidence is bad. With CODEX, whoever files it may prove it by any useful and relevant means (art. 326.2), and the court weighs it. It is not the same thing, and we do not sell it as if it were.
What we do put on the table: a SHA-256 fingerprint, a timestamp from an external authority and a Merkle root in a Bitcoin block, checkable by the opposing party with public tools and without going through us. In the Firm plan, CODEX also produces an expert evidence report with this framework and the verification protocol.
We are not a qualified trust service provider (QTSP). Acceptance is a simple electronic signature (eIDAS art. 25) with reinforced proof. Deeds and powers of attorney need something else, and we say so.
