Thanks. Maybe Pieczenik was actually on to something regarding the “blockchain sting” which was of course the original source. Not holding my breath but fingers crossed.

It would not be surprising that some kind of watermarking might have been applied to the paper used in ballot production.
But keep in mind that (like all other election matters) states do specify the process right down to paper and watermarking (e.g., CA statutes address both). So for any federal entity to override those state prerogatives might be a little dodgey, especially if done "secretly."
Hence, even if watermarking WAS done - and I'm personally skeptical due to the logistics of such a thing - I wouldn't expect that to be made public.
