1 ProofReg Registration Credit

One file, one moment recorded. Drop in your file and ProofReg records on the public XRP Ledger that this exact SHA-256 fingerprint already existed. Your file stays on your own computer; only the fingerprint and certificate ID are registered.

ProofReg records on the public XRP Ledger that a file already existed at a given moment, one credit per registration. Your file stays on your own computer; only the SHA-256 fingerprint goes to the ledger. You receive a certificate ID that anyone can verify publicly, even without ProofReg. Handy for that one idea, an important document, a recording, sketch, text or version you want to date — just to try it, or to lock it down properly.
