n then Big Brother can solve a Knapsack problem and keep tracking links between INs and OUTs using fuzzy logic. At some point in the future he may get more info and increase weights
* of some links.
------
* - weights r like probabilities, they range from 0 to 1
Which means distributing a larger transaction over time doesn't help much in case the weights are inevitably 1 or 0.
But in any other case, how could Big Brother possibly add your "more info" if all transaction in the past are fulfilled?
And the other thing: what's the issue with the 'joincoin approach'? I.e. if n senders send 5Nxts then n receiver receive 5Nxts. So, nobody could differentiate who exactly transferred whom 5Nxt. They send collectively n*5 Nxts and they receive collectively n*5 Nxts.
