This looks very cool. A clever solution to show that you hold coins without having to send them to a T address.
I would be interested in some sort of feedback from ECC, ZF or an independent auditor about the security of this method = that it can’t be gamed somehow by shifting funds around.
Or what happens if only a small % of ZEC in circulation are measured at the time of vote, is that “enough” for a valid data point?
Overall, love the concept, this could be a solution for things like the Namada airdrop.
