I feel stupid for not getting this but i have to ask. Does this mean that every user needs to be online solving the test at the same time in order to participate? It's the only semi-reasonable answer i am getting from this, even though it doesn't sound plausible or even reasonable. Please tell be i have been mistaken.
Its correct though might seem weird. Every Idena user on a planet needs to appear online at the same time and solve 5 flips in less than 2 minutes in order to prove their uniqueness. Consider it as a global online party.
A very original way to protect the network from fraudsters. If I understand correctly, the scammers will have to have one laptop for each account at the time of verification and several pairs of hands, depending on how many accounts they have registered. To organize such a very problematic, which makes your solution in the fight against multi-accounts very workable, I'm delighted.
