its not enough.
for purely digital money, the 1st mover has to be transparent.
Discussion
I think no because you loose fungibility. Money must be fungibel otherwise it is worthless.
Fungibility is a core characteristic of good money.
nobody would use digital money *at all* if the 1st mover wasnt transparent.
sure they would use it. I know Monero guys which never touched Bitcoin.
only because Bitcoin normalized the idea of digital money in the first place.
again
the idea that a chain of digital signatures could be money woudl get ZERO traction (except among cryptonerds and math freaks) if the first one wasnt transparent.
