The next person who claims that Dash has superior tech than Cryptonote is going to make my head explode. Lolz.
The people (person?) who write(s) Dash's white papers
can't even do high school level math.
I haven't seen a single person declare it has "superior" but just different it is obvious where you stand but I have to ask if it is so easy to attack the Instant TX why haven't we seen it widely happen?
Quote from upthread:
Arguments along the lines of "if that is true, why didn't happen yet" are refuted with:
1. Perhaps only I am the one who realized how to attack it. And I just described it today.
2. There isn't much incentive to do that attack, because (from what I've heard about most of the trading volume on altcoins being fake) there isn't any way to extract any significant value from Dash via shorting.
Perhaps the Dash folks should bet the Monero folks they can't attack the coin. And put up enough of a bet to make it worthwhile.
The Finney attack that I described can probably pulled off without needing to purchase a lot of masternodes. I am not sure which the attack will cause: a double-spend or a fork, because would require studying the code for Dash to discern the exact protocol enforced in that case.
I don't think anyone has the incentive to buy up 50% of the masternodes to do the other attacks (actually the attacks could be achieved somewhat infrequently with a much smaller % of the masternodes, e.g. with 10% of the masternodes every 666th UTXO could be jammed and every 10,000th UTXO could be spent as many times as desired). No one could gain enough from shorting on Dash to recoup their costs. The point is if Dash did become liquid and valuable, then the incentive might be there. The larger point is that if Dash were really adopted by millions of users, it wouldn't get very far. Maybe one could argue it would be fixed very quickly if adoption did start growing that fast. You are free to speculate on that possibility.
Remember these market caps for crypto coins are likely mirage. Insiders buying coins from themselves to pump up the price and the volume.
