Cryptographyanon here. I'm trying to make sense of Steve Pieczenik's remarks about "QFS blockchain encryption" watermarks on the ballots.
If you google for QFS, you find lots of references to a "Quantum Financial System", which is described as a future world monetary system and has nothing to do with US elections. It's just not relevant.
One thing which is completely certain is that there was no blockchain voting system used in this election. Those systems exist, but the experience of voting that way is nothing at all like filling out a paper ballot. It would be more like sending a bitcoin payment. That didn't happen.
So I think Steve Pieczenik misspoke when he said "QFS blockchain encryption". I think he meant either "QFS blocking encryption" or "QFS-resistant block encryption".
The reason I think that is that QFS is Quantum Fourier Sampling, which is the algorithm that quantum computers can use to break codes that classical computers can't break. China can do it. Any system used by the USA to protect ballots must be resistant to QFS attacks since China will have access to quantum computers when trying to forge the ballots.
There are cryptosystems that are resistant to QFS.
E.g.

So I think Pieczenik was saying that one of these cryptosystems was used to generate the watermarks on the ballots.
