I am so hungry. For example, I posited a way to continually increase the difficulty by always structuring the attackers blocks to make the fastest block solutions in the discarded 20% set, thus skewing the statistics of the hashrate. I wrote the caveat that I hadn't studied the implementation to see if this was feasible.
Structured how? Specifically.
According to the statistics used to choose the 20% set, and given the loose rules about the timestamps the attacker can put on his blocks. Again I said I didn't study the implementation to see if the actual calculation can be so gamed. It is just a conceptual point.
If the code was something I could quickly wrap my head around, I would have looked at it. I have not seen the algorithm used described in sufficient detail, like most things in Cryptonote, you have to go look at spaghetti code instead.
