Wonder if this may be relevant for the BTC mining scene?

"Yes, that's 154B - as in Billion. It was done entirely with AMD hardware, and involved 9x6990, 4x6970, 4x5870, 2x5970, and 1x7970 - for a total of 31 GPU cores in 6 physical systems." BitWeasil posted.

This could change the world!

Has anyone tried to set up a mining rig by renting out ILM's render farm for a few hours to see what would happen? :-D

I wonder if South Park Studios is mining for bitcoin between episodes Tongue

It's not.

1. Rainbow table attacks are useless against Bitcoin.
2. MD5 hashing is a lot faster than SHA-256.

He does, however, create a market for gently pre-owned GPU farms amongst the hakzorz community once ASIC takes over.

Sounds like distributed hash cracking to me, not new but hasn't been applied well in the AMD area. Nvidia will no longer be a unique OTS platform for this method. It's about time someone moved forward with this.

For Bitcoin to be a true global currency the value of BTC needs always to rise.
If BTC became the global currency & money supply = 100 Trillion then ⊅1.00 BTC = $4,761,904.76.

I just thought of why this could be dangerous:

The distributed/cluster version of OCLvanitygen would be able to get the private key of any BTC address.

Except not. Look up a few older posts by DeathAndTaxes to find out why and to see the math that supports it. Basically impossible unless a flaw is found in the algorithm.

Why, I can't put 8 or 9 characters into oclvanitygen and generate all possible addresses and their private keys?

Sure but it would take more energy than the Sun and several billions of years.

Well, a distributed cracker is only limited by the size of the cluster, the larger the cluster the less billions of years it would take. An intelligently redesigned oclvanitygen could reduce those billions of years even more. Cheesy

Edit:
Actual years rounded down to 1434 Quattuordecillion years for one core of a 5850. Now just need to figure out how many cores I will need... Cheesy

The other limit is physics.

If we truly understood physics, there would be an anti-gravity vehicle in everyones backyard. Cheesy
According to Boyd Bushmen, retired senior engineer for Lockheed>Martin, there are 8 fundamental forces and we barely understand 5 of them.

However, the relationship between entropy and energy is one of the few things we do understand.
