The OP is missing some key aspects of blockchain POW mining. The coins are not under millions of rocks where they could be instantly mined. Each block can only be mined one at a time. The block is just a bunch of transactions (or state changes in smart contracts) that need to be processed by the distributed system. In fact, the coin reward is just a clever mechanism to incentivize nodes to process these blocks.
With quantum it might be possible to mine each block very quickly, instead of the average 10 minutes we have now, however any chain would just fork to us a new system. As other commenters have pointed out, the real issue is the asymmetric keys that controls the use authentication and wallets. With quantum you would effectively be able to access anyone's wallet, deriving their private key through quantum brute force. Not to mention HTTPS etc. The fact that blockchain is an immutable ledger (and generally public) is an even bigger issue.
There are various ciphers that are considered quantum resistant. Most real time systems like HTTPS will likely switch to them. However pre-shared traditionally encrypted data (or wallets) could be a major issue.
Until 2008, Oklahoma experienced an average of one to two earthquakes of 3.0 magnitude or greater each year. (Magnitude-3.0 earthquakes tend to be felt, while smaller earthquakes may be noticed only by scientific equipment or by people close to the epicenter.) In 2009, there were twenty. The next year, there were forty-two. In 2014, there were five hundred and eighty-five, nearly triple the rate of California. Including smaller earthquakes in the count, there were more than five thousand. This year, there has been an average of two earthquakes a day of magnitude 3.0 or greater.
The first case of earthquakes caused by fluid injection came in the nineteen-sixties. Engineers at the Rocky Mountain Arsenal, a chemical-weapons manufacturing center near Commerce City, Colorado, disposed of waste fluids by injecting them down a twelve-thousand-foot well. More than a thousand earthquakes resulted, several of magnitudes close to 5.0. “Unintentionally, it was a great experiment,” Justin Rubinstein, who researches induced seismicity for the U.S.G.S., told me.
Yeah it's gotta me shielding. Put two racks side by side with a lead or some other kind of shield from "cosmic ray-induced neutron strikes" on one rack. I'm guessing that gravity probably has a negligible effect on this entire test. it's probably more about the amount of atmosphere above the racks at different altitudes.

While this may not cause immediate long term damage to the naked eye. I read something over a year ago that in all the tests, they made the subjects remove their contacts. Apparently, the contacts can melt and bond to the eye. While we might like to believe that no one in the crowd will be wearing contacs...this is just not the case...

The software the MS is refering to is the Save/SaveNow software from WhenU. MS is attempting to be consistent, however there are significant differences between GAIN and Save.
Hilary Rosen was in the position to fix the situation, but instead she helped create a locked-down DRM-prolific online music space. It's funny to see her complain about the exact problem that she put into place.
Wasn't it easier when we all just had MP3's? Funny how that format works with everything.

Enterprises will need blockchain solutions. Good to see AWS joining the fray, though much of their offering is centralized.
However they took their time given where players like Microsoft and IBM are doing.

It would be great to have these articles before the deadline.
Actually there has been damages. read up on it. http://www.newyorker.com/magaz...
This is due to water injection wells as a result of fracking and other oil/gas drilling.

This whole BR and HDdvd stuff is just dumb. Why do I want all new hardware to play some new bloated medium? You can already get 1080P content on DVD's..you just can't play it on a DVD player. Too bad the labels will never put HD on DVDs. http://www.microsoft.com/windows/windowsmedia/musi candvideo/hdvideo/coralreef.aspx
