This is an interesting debate.
I agree that the NSA can kill Dash, and Dash is finished. And I am sure they can kill Bitcoin too, but I am sure they cannot kill Dash without we would realize. I am not so sure about Bitcoin.
Check the masternodes/country here:
http://www.dashnodes.com/index/charts
26% US
25% Germany
20% France
13% Netherlands
etc.
With all US masternodes under control the NSA cannot denonimize the transactions. Let's do alternative scenarios:
1.- They buy XXXX Dash to create new masternodes (we can do the math to find the exact number is necessary to do it, it's a lot). The market goes crazy, we would realize. They control the network but they can't know past transactions (Masternodes don't do that, users are secure). Dash is finished
2.- They can "invade" or "hack" us the poor Europeans (France, Germany, Netherlands, etc.) get access to our accounts in our european servers. We would realize (yes, we would), they can control the network, they can't control the past transactions (Masternodes don't do that, users are secure). Dash is finished
I think the NSA can kill, but they can't control the Dash network. How you see it?
(excuse my grammar and vocabulary mistakes, english is my third language)
Some European countries share meta data with US agencies and even have more power to capture data than even the US due to less strict rules on spying agencies, but that doesn't diminish that foreign servers are sometimes owned by American companies already working with the US government or that can be forced, coerced, or bribed into supplying information. Never mind that Dash's Dev Evan has too much power over Dash's direction (and its assets) and can be coerced by US operations to help or hinder Dash with the mere threat of a FinCen investigation or a compliance document similar to those that were used in Prism to get some of the biggest companies in the world to hand over unbridled access to data--either you don't get how much of a vestige interest all countries have in controlling information and finances or you overestimate Dash's ability to cope with these measures.
How would you realize the network is compromised if Evan was coerced into working with investigators? Cut the head off the snake and it dies, control it and you can decide where the venom goes.
Here would be my gameplan if I wanted to control Dash:
If Patriot Act rules are engaged, I would send a letter of complicity to Evan and have him work with my agency to glean as much information from the network while also creating more backdoors to glean information. If he chooses to fight the complicity order, I would green light a FinCen or SEC or FBI investigation with the power and scope of this investigation dependent on if he plays ball or not. If there weren't Patriot Act rules in play, I would move immediately to step two. The goal would be to control Dash, not to destroy it.
I don't know the other players in Dash, but thanks to the instamine, they seem like a small group and most likely could be gotten to and forced to comply. To put the risk to US power in perspective: Gadaffi had an army and lived in his own country and had vast personal wealth, but was expelled from power and put to death after he talked about not accepting US dollars for oil. Do you think you can pin your replacing-all-the-world's-currency hopes on a guy who lives in Arizona, couldn't get the details of his coin launch in order, doesn't understand (or care) that masternodes are a major attack vector for a cryptocurrency, and renames his coin every five months? That guy can be gotten to and i'm pretty sure it doesn't take a needlessly expensive revolution to do it.
Good answer! Quite a work kill Dash in your gameplay, right? NSA, Secret Service, Patriot Act and threaten Evan. All without a single leak of information. Not bad!
Assuming your scenario, let me tell you a little secret: Evan is not alone anymore. UdjinM6 is a core developer from Russia, and he is as much talented as Evan (you can check Github about that). And I am not sure UdjinM6 would agree about spying for the NSA. You know, russians are tough guys.
And I am not sure NSA can go to Russia and force UdjinM6 to cooperate to control Dash, you know Putin is a person of temper.
Dash is open source! And Dash is not Evan. Evan can write it, but you can check and review the code. UdjinM6, Flare, Crowning, elbereth, Francis, etc. All the members of the Dash community and the general public can check the code.
And this is bad for backdoors and is good for transparency.
