Proof

Every few seconds the XRP Ledger closes a ledger and its validators sign it. This page checks each signature itself, in your browser, and inks the certificate only with what it has checked.

How to read it

Seven stops, about a minute.

The columns: One per validator on the list you trust (35 today). A column fills with ink when your browser has checked that validator’s signature on this ledger.
The roofThe ring beam: It goes upIt is set under the dome once 28 of them have signed the same ledger. That is the quorum.
The domeThe star: Its rays appearThe star the telescope is trained on sends out its rays when the ledger’s header hashes to exactly what they signed.
The telescope: Inked when an account you look up is proven against the ledger: its entry hashes, node by node, up to the state root.
The steps: The validator list itself, signed by the one key you trust.
The signatures: Each is drawn from the actual bytes that validator signed on this ledger.
Backlight: Hold the sheet to the light: the trusted key is in the paper, as a watermark.
Ultraviolet: The names of the validators whose signatures were checked fluoresce.
A receipt: Paste a transaction hash in the box below. Your browser proves it and makes a PDF receipt that carries its own proof: drop it back on this page, now or years from now, and every check runs again.
