Yes they do
.
Those asic farms make sure no 10 yo with 1000$ on this father cc can buy a botnet and play with the chain as he wants
.
So , what is protecting quark against this kind of attack?
While it is not a substitute for a strong network, Quark is protected by its checkpointing. Every 12 blocks, the blockchain is signed by the checkpoint - meaning that every 12 blocks, the blockchain becomes hard-coded. Therefore, if a person wanted to double spend, all the accepting party would have to do to prevent that from occurring and seeing that they in fact did not send payment and are trying to commit fraud is to wait for 6 minutes or 12 blocks, at which time they would see that the transaction that they are accepting in fact has been removed from the blockchain. At that time the accepting party would simply have to not send the purchased material since there was non-payment.
The Foundation would not allow a "10 y/o with $1000" to successfully attack the network - we have a lot more devoted resources than that. Many other coins could be attacked by someone with enough means - that is not isolated to Quark. Theoretically one of the ASIC manufacturers for sha256 or scrypt could simply run a large proportion of their production line of ASICs themselves and play the same sort of havoc you're describing. The whole system is based on some element of trust - which will be reduced as the whole landscape evolves. Quark is less than 1 year old - we are at the start of our life-cycle, not the end.

Do you have a clue what a 51% or a 90 % attack can do?
Do a bit of research , you're getting the wrong idea
.
Do you have a clue how to use emoticons? Have a look at passive aggressive communication, and think about how you come across - unless you like being a psychopath that disrupts every thread you post in
I was a critic of quark long before you made your account;).
I didn't like the distribution curve nor it's so called cpu friendly algorithm.
Right now ,I couldn't care less about the premine if it was any or it's projects or future
It just shows me how weak a coin with practical no rewards and no transaction fees is
How nice of you to tell us all what you don't like. Constantly.
Let me guess, you were an early adopter of Bitcoin and did well enough to quit your job, and now, you spending your time 'protecting your investment' by trolling messageboards and posting FUD about the competition. How sad.
I am not an early adopter , I haven't quit my job and It's my pleasure to remind quark fanatics that their coin is 1/10 of the value they bought in December.
Also , unlike you zealots I had a bet with cryptohunter and I admitted in this board and pm'd him that I lost it and for the the 7 days trading time quark was a better choice than btc.
But , you're the type of blinkered commie zealot "who's not with us" is an enemy! Stone him to death!
Competition? If bitcoin needs trolls to protect it from qrk , then bitcoin deserves to die.
Typical retarded logic above , using the same argument to attack or semi passively threaten confidence would give a fat loser like this a hard on.
How scared do we all look ?
He kind of reminds me of the main stream media that is still trying to "shape opinion" while all the time people continue to tune out.
It's that sort of misplaced ego, the failing empire type.
" how you going mum yeah today I threatened some people on a forum, but you'd be real proud of the way I did it , I kind done it with a smile icon ....."
" wow son that's great , how's world of warcraft ..."
"have the NSA or in-q-tel offer you a job yet , like a real one ? "
