Good + Crazy = ?
Another idea, the NashX idea, is to just destroy all Trader's money if the network fails to agree (Global Certainty between .4 and .6). This has the drawback of being insane, but it is very incentive-compatible. You would not 51% attack such a network (buy up 40-60% of the Votecoins solely to gain nothing).
People don't usually like this because they intuitively perceive something called the "trembling hand" (accidental / irrational / forward-induction-threat-credibility-building-rational destruction of their entire payout). I don't think the trembling hand is as relevant here, as we can make it costly and complicated to trigger, with multiple people needing to make costly mistakes.
How would that solve anything?-- According to your definition Global Certainty is a aggregate average of all decision contracts. A attack could just vote correctly for 99% of all decision contracts to make Global Certainity at 99%, but vote against one decision contract-- the Hillary Election 2016 that has millions on the line.
Would it be better to refine this-- Global Uncertanty Penalty for specific contracts. Only top 5% (or something else) Decision Contracts by truthcoin market value would be subjected to this penalty. Where if a contract represents greater than 5% in value out of all those in the period and network fails to agree on its particular outcome, then the money in that decision contract would get destroyed. So instead of destroy the trades of all decision contracts-- you would be destroying the one contract.
