Overview

A Truestamp timestamp is a cryptographic submission window, not a clock reading: proof that data was submitted after one internal block and before the finalized block whose Merkle tree includes it, the submission window. Both edge blocks are committed to public blockchains, which is why the home page can promise timestamps that are immutable, independently verifiable, and impossible to backdate, forge, or alter. Timestamp is the first of the three pillars in the product framing (timestamp, integrity, provenance), next to the sibling terms data integrity and provenance. A timestamp is deliberately never a creation time claim: it proves when data was submitted, and says nothing about when the content was originally made. The timing guarantee is covered in the submission window and the affirmative guarantees in what Truestamp proves.
