Could you elaborate on how it is exponentially expensive? I don't see how that would work. If 100 people are allowed to vote on a topic with this system, then one person with 100 sock puppets should be able to vote on a topic, as there isn't a technical difference.
That's also how I see it. There is nothing exponential about it. The cost for someone using a sockpuppet to vote for a post is exactly the same as for anyone else.
So either you have to make it really expensive to vote and that would make this a no-go or you end up with cheap advertisement that you can't even block easily.
There is one trait to this system that is interesting: the cost to promote your content goes up with the rate of popularity of other posts. Kinda like in the real world where advertising on a popular page costs more than on a random blog.
But because there is no limit as to how many people would try to advertise, the whole content would soon be pure ads.
It looks like funding all those sock puppets with coin would cost lots of money.
From the slides:
Sending 10 points to someone would require 10 addresses
with at least 2 points each. Creating 10 addresses with
2 points each would require 10 transactions of 4 points
each, meaning 40 points.
Those 10 addresses require the same funding amount whether from sock puppet accounts or from one account.
Well to acquire a point you can use in voting would have to get one from a miner. That would be the same, no matter if you are a real person or an advertiser/spammer. Unless you gained points before with your own content.
Even if the price would be 4x the amount of the cost of other votes, it can't be a deterrent because 4x a little amount is still a little amount. If a vote costs 1 cent then the spammer would pay 4cent. Not a big deal.
