Emailing yourself feels like proof, but it stays private and relies on your provider. ProofReg records the moment on a public ledger that anyone can check.
Private and provider-dependent — versus public and verifiable.
ProofReg records the fingerprint of your file on a public ledger; emailing yourself keeps the file privately with your email provider.
Sending yourself an email with a file attached is an old trick to have 'a date'. The problem: that email sits in your own inbox, the date comes from your provider, and no one else can check it independently. In a dispute that is hard to stand on.
ProofReg works differently. You record the fingerprint of your file on the public XRP Ledger, with a timestamp independent of you and your provider. Anyone can later check that exactly that file existed at that moment — without you having to share the file.
ProofReg and emailing yourself differ mainly in who can check it, how independent the timestamp is, and how hard it is to change.
Email: only you. ProofReg: anyone, via a public verification link.
Email: the date comes from your provider. ProofReg: the timestamp is on the ledger.
A ledger registration cannot be altered undetectably afterwards.
With ProofReg your file stays yours; only the fingerprint goes to the ledger.
ProofReg is for the moments where a private email is too little to stand on.
For a simple reminder to yourself, emailing yourself can be fine. But once it counts — a client disputing the version, an agreement in question — you want something independent of you that the other side can also check. That is exactly where a public ledger registration makes the difference.
With ProofReg Duo both parties can moreover independently record the same version, so it does not become your inbox against theirs.
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. 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 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.
Not worthless, but weak: the email is private and the date comes from your provider. ProofReg adds an independent, publicly verifiable timestamp that does not sit in your own inbox.
No. Your browser calculates the fingerprint locally; only those 64 characters go to the ledger. Your file stays on your own computer.
