No, it's just 1000 times less likely to happen, but it does happen (in fact it did happen). It's just very rare.

Another "good" block was found recently by P2Pool:

I calculated this would be good for a difficulty up to 78,688,747,242 (not sure the math was right, though).

No. Each hash attempt is independent of all others, so each hash attempt has the same probability of solving a block as all others.
When you have more powerful hardware, you are simply making more calculations within a set time frame. When hashing rates increase, there is a greater probability that larger hash sums will be discovered within that set time frame.
So, no, it didn't take "1000 times longer to find." But, on average, you would solve 1,000 blocks at the lower difficulty in the time it would take you to solve 1 block at the greater difficulty. And who knows, maybe someone will submit a share tomorrow at a difficulty 1,000,000 times greater.

It's effectively random. The actual value doesn't matter as long as it's greater than the difficulty. Solving a block with an effective difficulty value greater than the actual difficulty doesn't represent wasted work, because solving a block is brute-forcing SHA256.

Caan some1 explain the significance?
Every share has the potential to be a block, if the difficulty of that share is higher than the network difficulty. When Bitcoin was first starting off, every share that had a difficulty of 1 or more was a valid block. Then 2. Then 500. Then 100,000. Then 3 Million. Now it's 149 Million. You get the idea. It's going up, which makes it more and more difficult to find blocks.These block solvers are shares that were not only just above the network difficulty of the time, but also astronomically higher. Right now, a share with a difficulty of 151 Million and 151 Billion would both be block solvers, and both earn you the same amount of BTC, but the second one is 1,000 times harder to do.
For me, it's just a cool little fact to see how high luck has been pushed. The odds of getting a 237 Billion difficulty share are insane, but it still happened.
The only possible benefit is to prove that when Next-gen ASICs push the Network Difficulty to 1,000 times what it is today, we will still be able to find blocks. How? Well the shares have already been found, and they're accepted, and still working. If we found a 237 Billion diff share in 2013, we can find another one again in 2014 (or 15? Idk) when it's required.

Found a new (hopefully) largest share out there...

Thanks for that!
So that's ~173 Billion? Geez.

A share or a block solve is a really large value in hexadecimal and the difficulty is compared to the highest possible share value
FFFF0000000000000000000000000000000000000000000000000000
so gigavps' share was
d4f9920e216f89a0ac30010ddfec3ebd3f70602e377fdb26
the difficulty of his block solve was
FFFF0000000000000000000000000000000000000000000000000000 / d4f9920e216f89a0ac30010ddfec3ebd3f70602e377fdb26
Not many calculators work very well with 256bit integers, but anyway that comes to 5,162,556,379.

How does one calculate the difficulty of a hash? I wasn't able to find anything via Google. Would love to know!
Damn, not even in the top 10.
If you don't mind, can you put the calculated difficulty next to each hash?

I've got these blocks as the top ten:

That block has a share difficulty of 5,162,556,379.
Is this the largest BTC share diff ever found?
