Thanks for the book recommendation. This has been something I've been thinking about for several months now: how would a p2p exchange possibly implement a time-price priority queue to ensure proper order execution? The more I think about it, the more I convince myself that it is likely impossible to get network incentives to line up correctly without relying on a trusted third-party (or making other show-stopping compromises). Nodes have no incentive to rebroadcast orders that conflict with their own, and any sufficiently motivated attacker could place nodes in strategic places in the network to manipulate execution in their favor. If anyone wants to talk about this in detail, shoot me an email.
