Your fears are kindve coming true already. ghash.io has way too much hashing power.

ghash.io is a pool, not a cloud mining company. The danger was from too many miners on it, which was solved within 48 hours through a community awareness campaign.
Fortunately the danger is entirely immagined: Cloud hashing can be pointed at any pool. Individuals still vote with their dollar. Therefore there’s no danger that a group of individuals (cloud hash purchasers) will give another individual (a pool operator) enough power to consistently devalue their investment. Such actions would not be rational at all. You all can sleep soundly at night again, cloud hashing won’t destroy the network. Promise.

Rational implies eyes on the ball. Easy service equals less attention. Hence middlecoin.
Cloud hashing has negligence issues.
And of course there’s always the suicidal attackers who want to see alts gone.

The rate of a collision is so low that Bitcoin doesn’t even bother checking if the address has been used. It just generate one randomly without any communication to other nodes.

This part litlle freak me out…
Just got an email from BTC-e claiming that I have requested a password change, which I obviously didn’t.
I for one am now genuinly concerned, although all passwords I use are different. Please take this seriously and CHANGE YOUR PASSWORD(S)!
Just wanted to give you guys a heads up.
I only agreed to add the karma option in the first place if I could remove smite. I’ve found a fix that will persist beyond site migrations as it is on the database side.

Let’s ignore the math for one moment, which is what prevents such attacks from being possible.
Let’s assume that such exploits are not only possible, but they actually exist.
What would the price for such a thing be?
I can imagine it having 2 prices: A billion dollars, and 0 dollars.
Why a billion dollars? Well you’ve effectively got one better than a money making machine (which is what mining rigs are): A money stealing machine that steals money from all the money making machines. If that were true, a billion dollars would be cheap.
Why 0 dollars? Well let’s assume this exploit worked, and your coins could be stolen/intercepted/hacked. What would a Bitcoin be worth if it could be stolen? About 0 dollars I imagine.
So, do you REALLY think someone’s going to give you this for the cost of filling out an online survey? Really? Because if you do, I’ve got some ebooks for sale that you’re going to LOVE and at a really affordable price too!

Yes, somethimes my mind gets really deep frozen and thoughts slumber around… Things looked to real, but yeah those game patches/cracks are also distributed this way but i never tried it …
I was thinking maybe some people trying to destroy cryptoCurrency…

It isn’t but it will be soon…

Good news. That’s the assumption I was under (think I read it somewhere all ready)
From all the articles I’ve read that keep popping up, It’s the major criticism at the moment.
[s]I’m sorry but i responded to the wrong post with the wrong quote and statement i think.[/s]

Chris and Emtimp are heading up a Feathercoin web site update,
I am also thinking of others novel ways we can give anyone the chance to contribute to that project, but maintain a high standard of “product”. Also, conserve all the important and subtle ideas that went into Feathercoin website v2.0.
nice posts rep+

I was watching my synchronised feathercoin running over IPv6 only just now when all of a sudden my feathercoin-qt client’s statusbar changed into the “Synchronising with network” appearance and now it says it wants to add 345769 new blocks, the last block was generated 51 seconds ago.
What does this mean?
I have some logs but they contain IP addresses so I won’t post them here, ask if you want them.
This smells fishy…

It connected to a Litecoin peer.
Part of the NTP protocol is, that the client can syncronize with several NTP server.
If more than one server is configured, it selects the one with the best stratum value.
If several with the same stratum are configured, the client will do a round robbin at every start of the NTP protocol.
This means, that an Attacker must spoof more than one server to be sure, that a sufficient number of clients are on the fake time.
Also as there are a large number of NTP server available in the Internet, and most people use NTP server located on their continent, it would be a huge effort to attack the network by spoofing NTP servers, as an attacker would have to spoof several NTP server managed by several provider/companies all over the world.
I don’t see a big risk here.
