Disclosure

This site may reference timestamping services and verification platforms where they implement patterns the reader is evaluating. References appear because the service is relevant to the described workflow, not because of a commercial arrangement.

ProofTimestamp is editorially independent. Sponsored placements, affiliate links, or paid inclusions are disclosed visibly on the page where they appear.

If a page includes a reference to Provncloud, that reference appears because Solana timestamping is directly relevant to the page topic, and Provncloud implements the pattern the page describes. The relationship is disclosed on that page. Other timestamping services are referenced where they present meaningful alternatives.
