    Incentives are misleading & dangerous basis for security unless objective math (computer science) done first & much engineerng margin added.

        Yet #bitcoin security rests on economic incentives and statistics every bit as much as cryptography and computer science.

        Which leads to oversimplification. Will need to shift to complex adaptive mechanisms. Cybernetics more useful than game theory.

        CAS especially important when entities themselves have models of the systems they are in.

        All Economics can do is Rational Expectations theory. This absurdly assumes each entity has same model of system, the one the economist has.

        gametheory does not require speculation, guessing if people follow it does. As a poker player I would say they dont..

        GT & Economics assume so-called rational behaviour. This assumption inappropriate for computational systems because code can be buggy.

        Also remember that the axioms of Game Theory can derive probability theory and Bayes Theorem. Use prob. to express knowledge of outcomes

        Prob theory is just one among many formalisms for representing uncertainty. Not necessarily the best for any particular application domain.

        Maths of uncertainty studied since 1660s. Prob axioms since 1920s. Still no agreement on semantics of prob statements. Topic is hard.

        We can't do this job. Bitcoin shouldn't need us too. It must be physical not ideological. The specie; the issuance.

        Are you implying the game theoretic framework for 'proof of stake' is not better than 'proof of work'?

        The maths of game theory also does not scale well. Many players, action-options, payoffs, leads to intractable math.
