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:

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

Solving a puzzle gives miners a much higher chance of solving the next one

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.

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.   ::)

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?

You didn't read the link, as it answers that question.

i researched a bit on the OP and he just sounds looney http://www.cuongvtruong.com/

refers to himself as "his majesty the King." he is a prophetic "son of god in the 21st century."

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.

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.

Yeah, that would be a pain. I only have 8 terrabytes in my main server right now. But chances are that by the time we get to that point, 1 terabyte will cost as much as 100gigs do today. Also, don't forget that pruning will keep things from growing too fast, and many of the transactions in the new block will clear out transactions in the old blocks.
But, yes, in the long run, this will have to be handled by data centers of wealthy hobbyists (such as bitcoin early adopters), while most users will just use SPV.
