Record what the order stated — item, quantity, price and delivery date. With ProofReg Duo, buyer and seller independently confirm the same version.
One order you both agreed on.
ProofReg records the exact version of your order on the XRP Ledger, with an independent timestamp.
An order states exactly what was ordered: item, quantity, price and delivery date. If the delivery later differs, or there is disagreement over the price, it comes down to what the order stated at the moment of ordering. Record that and you have a verifiable reference later instead of two versions of the same story.
You put the order in a file (a PDF or photo) and record its fingerprint. Only those 64 characters go to the ledger; the order itself stays yours.
ProofReg helps at any moment where the content of the order might later be questioned.
Record the order, so later it is clear what was ordered.
The price on the recorded order is beyond doubt.
Register the confirmation, so the order is verifiable.
The more it states, the more a fixed reference matters.
ProofReg records your order in three steps: put it in a file, record the moment, and verify it later.
A PDF or photo of the order. Your browser calculates the fingerprint locally; nothing is uploaded.
The fingerprint goes onto the public XRP Ledger with a timestamp. With Duo the other party independently confirms the same order.
You receive a certificate id and verification link. Anyone can later check that this order existed then.
ProofReg Duo lets buyer and seller record the same order independently, and completes only on an exact match.
With Solo you record the order — enough to show that and when that version existed. With Duo the other party independently records the same order; only on an exact match is Duo complete. That fixes that buyer and seller had the same order in front of them.
ProofReg Duo does not prove the delivery was correct; it proves you both held the same order. That is usually exactly what the dispute is about.
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 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.
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. 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.
Yes. A ProofReg certificate states the fixed anchoring account, the certificate id and the issue date. With those, it can be verified in a few steps on any public XRP Ledger explorer, without ProofReg.
ProofReg records which order existed, not whether the delivery matched it. The recorded order is the verifiable reference to hold the delivery against.
Yes. Export the confirmation to a file — a PDF or screenshot — and record its fingerprint. With Duo the other party independently confirms the same version.
