Got a CMI signal from Telegram, a friend or a group? Type its numbers here to check they are exactly what CMI recorded when the signal was sent. Someone reposting CMI signals with changed numbers will not match.
This checks against CMI's own stored record, where signals are never edited after they are sent. Proof that does not rely on CMI — each day's record hash published on GitHub — is shown per day on the record page once anchoring is switched on.
