Discovery hash

[davidjackson]

I would suggest the best way to do this without creating unnecessary threads would be to use opentimestamps.com and email yourself the file.
If you want to use the forum as a timestamp authority, something we are not setup to do, you could always PM yourself the file and use our timestamp in the DB as later proof, although I would be unable to do anything specific to prove this later on.

You could also add the hash to your bio, which is public.
