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://bitcointalk.org/index.php?topic=324413.0

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

Bitcoin is the first monetary system to credibly offer perfect information to all economic participants.

As far as I know, that's not how it works. Is it?

What everyone does when they "discover" a flaw to get bitcoins easily:

1. Get bitcoins easily, and then go do media with proof of what they did and could do

2. Claims they know how to do it <---------------

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.

Bitcoin's true purpose defined in Satoshi's message on the Genesis Block:
"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"

Except Visa and Mastercard have nothing to fear from Bitcoin, since Bitcoin doesn't scale and could never handle the transaction volume of either.  Let's not even start with banks and actual real world currencies.   Roll Eyes

If your ignore button isn't glowing, you're doing it wrong.

According to people who actually know what they are talking about (https://en.bitcoin.it/wiki/Scalability) Bitcoin scales quite well, and can easily do many times the transaction volume of Visa and Mastercard.

It's getting old.

Amazing how much coverage a half baked paper gets that has not even been peer reviewed, yet.

The "problem" has been discussed years and years ago.

It's pool mentality.. I suppose that explains all those "xyz pool is hiding block data from us"
It's competitive against waves of increased hash power, but the kind of competition that US persons are not accustomed to. They risk splitting the chain each time to a degree the bitcoin supersystem May or May Not be Able to handle. Of course the typical doom is heard from the shortsighted.

Will it be able to run on anything except NSA supercomputers then?

30,000 tps == 5.85 MiB/s (30000 tps * 0.2 KiB) == 493 GiB/day (5.85 MiB/s * 86400 s)

If u mean SPV mode... I'm talking about the full mode. Half a terrabyte is the lowest bound assuming transactions r very small. My HDD will be filled completely within 2 days. Maybe it's just my problem.
