We'd need to get Alpharisc to state it for the scenario he foresees for XC. But the problem in general concerns two "rationally self-interested" prisoners who (a) get out of jail if one betrays the other prisoner, (b) get a longer sentence if both prisoners betray each other, or (c) get a shorter sentence if neither of them betray the other.
Edit: the idea is that it's rational to betray the other prisoner. However things get more complicated in the iterative version of the dilemma: prisoners get to repeatedly choose to betray or not betray one another. Alpharisc, to my mind this plays into the hands of a WOT model as long as it's combined with a means of punishment. What's your view?
Ok I think I see. The node holders need to decide whether they betray (and take coins)??
Yup, I presume Alpharisc anticipates something like that. But I wouldn't want to put words in his mouth.
He would need to state the scenario - if not with rigour then we'd have to build up a rigorous account of the problem (if it is a problem) through conversation - after which we'd be able to present it to the dev and improve the coin.
THIS is what these forums are for. How I wish they were employed appropriately.
