A submission returns a pending attestation; the Bitcoin attestation is fetched later by upgrading the proof. timestampStatus says which of the two these proofs currently are. Editing any past day breaks every anchor after it.","whyItMatters":"Anyone can rebuild this software. Nobody can produce a Bitcoin-backed timestamp dated earlier than they created it. That is what makes \"observing since\" checkable rather than claimed — once a proof is upgraded. A proof still pending rests on the calendars' own records instead, which is weaker; timestampStatus reports which applies.","verifyWith":"https://opentimestamps.org — take chained from any entry, decode its base64 ots proof, and verify independently of this service.","hint":"add ?full=1 for every daily root and its OpenTimestamps proof"}
