The forked chain will be orphaned when published.

Perhaps you should understand the attack before lambasting someone else's misunderstanding of it.

"Hey! The Bitcoin protocol allows for a 51% attack!"

Wow. Thanks, Business Insider.  Roll Eyes

Then again, maybe I should be a little lenient. It's not as if everyone knows about it, and it may sound alarming to some hearing it for the first time.

Still though, to suddenly act as if you've found some secret, previously-unknown "flaw" and to speculate on it leading to bitcoin's collapse... I guess such a thing makes one a journalist nowadays.

You're going to see more and more of these nonsense articles as Visa and Mastercard and the Banks start to worry for their profits.
Scaring people away from Bitcoin will be the most effective and common way to stifle its growth.
One mention of "hackers" and most people would never put their money into such a risky environment.

I think you're right, but it's ok. I think it's ok if BTC is slow to be accepted, although so far I think it's moving pretty fast.

The article and so called research is total crap. It is a modified version of so called 51% attack. And Bitcoin does not assume that all nodes are honest, quite the opposite! For this attack to work you need a large pool and brain damage to not publish mined blocks. And all it can do is create blockchain fork that is shorter than the main chain (because >50% of hashing power is working on properly broadcast chain). The forked chain will be orphaned when published.

It's a fine strategy in the short term, except that it loses effectiveness over time. People who've been aware of Bitcoin for a while have heard many news stories about its imminent death, yet it still exists and gets stronger over time.

Eventually "The Boy Who Cried Wolf" Syndrome kicks in.

Earlier post with same/similar topic here:

https://bitcointalksearch.org/topic/bitcoin-flaw-could-let-group-take-control-of-currency-325225

Old and overblown news. Here's the more detailed tech thread on it, which notes, among other things, that the basic idea of this attack has been discussed for 3 years now:

https://bitcointalksearch.org/topic/majority-is-not-enough-bitcoin-mining-is-vulnerable-324413

Something to be addressed long-term, but not a big deal. This thread's title is pretty misleading once you understand the issue.
