Write out your idea, and register the fingerprint of that file on the public XRP Ledger — with a verifiable timestamp, before you discuss it with others.
A verifiable moment, before you share it.
ProofReg records that your worked-out idea existed in a file at a certain moment, with an independent timestamp on the XRP Ledger.
You often discuss an idea with others before it is finished — an investor, a partner, a client. It helps if you can later show that you already had that write-up at a certain moment. Put your idea in a file and record its fingerprint with a verifiable timestamp, without giving away the idea itself.
Only those 64 characters go to the ledger; your file stays yours. To be honest: ProofReg proves this file existed then — not that the idea is original or yours. An idea itself is moreover not a protected work; that is a separate, legal question.
ProofReg proves the existence of a file at a moment, and explicitly leaves originality and ownership out of scope.
ProofReg helps at any moment where it later matters that you had already worked out your idea on a certain date.
Record your write-up before you share it with someone.
Register your plan with a verifiable moment.
Record which version existed before you continue together.
A timestamp per version makes your timeline verifiable.
ProofReg records your idea in three steps: put it in a file, record the moment, and verify it later.
A text, PDF or sketch with your write-up. Your browser calculates the fingerprint locally; nothing is uploaded.
The fingerprint goes onto the public XRP Ledger with a timestamp. Your idea itself stays private.
You receive a certificate id and verification link. Anyone can later check that this file existed then.
ProofReg automatically creates a certificate with every registration and anchors that certificate itself on the XRP Ledger too, at no extra cost.
You receive the certificate by email. The certificate can carry the email address it was sent to; because it is delivered by email, whoever holds it had access to that mailbox at that moment — so the proof is tied to an email address, not to a verified identity.
Because the certificate itself is on the ledger, no one can undetectably alter or backdate it afterwards — not even us. So even your proof has a proof, which anyone can verify without ProofReg.
ProofReg records that this exact SHA-256 fingerprint, with the label and registrant you entered, existed on the XRP Ledger before the recorded ledger timestamp. That is independent and publicly verifiable, without sharing the document.
No. ProofReg is not a notarial service and does not establish copyright or a patent. ProofReg dates the existence of a fingerprint on the public ledger. It provides proof of existence-on-a-date — often exactly what you need before you share, submit or publish something.
No. Your browser calculates the SHA-256 fingerprint locally. Only those 64 characters, plus an optional label or registrant you choose, are recorded. The file never leaves your computer.
ProofReg Duo lets two parties each record the same document independently. Only when both fingerprints match exactly does the mutual registration complete. It proves you both held the same version, not that you agreed.
A registration costs from €1, paid with credits. Verifying a certificate is always free and account-free.
No. ProofReg records that your write-up existed at a moment; it does not make an idea exclusive or protected, and proves no originality. Those are legal questions outside ProofReg.
Yes. Your browser calculates the fingerprint locally; only those 64 characters go to the ledger. The content of your idea stays on your own computer.
