Research paper can be faked and neither you or me can write Code so that page is pretty much useless to both of us,
I am not entirely versed in cryptography research papers although I study the WabiSabi whitepaper from time to time, but the paper definitely isn't a fake (unlike low-effort papers created by memecoin developers by comparison, if any).
Although since I can't demonstrate how any of the theorems work, I can't actually prove that, but it's commonly accepted to be the case.
