I think there is a known pattern where you post the hash of a document, e.g. on Twitter, in order to have its time registered. You could then later publish the document and have it accredited for the time of the hash.

I'm sure someone gave this procedure a name. What is that name?

I found trusted timestamping, but that is a thing for digital certificates, which do not come into play here.

    No, don’t delete the question! It could help someone else in the future. Instead, it would help if @JosephSible-ReinstateMonica was to add their comment as an answer you could accept. Jul 27 '20 at 5:08
  • @JosephSible-ReinstateMonica If you answer the question with a bit more than a link-only answer, I'm ready to give you some virtual internet points ;-) Jul 27 '20 at 6:35
