The search for nonces changes every 10 minutes.  An address with a lot of coin might be in cold storage and you might be able to search for months uninterrupted and your reward might be very high.

Seriously? "Why not just steal instead of helping to secure the network of a possibly world changing technology?" Are you that moronic?

Forget the moral problem everyone will have with your theft. If you steal a large block of bitcoins (assuming you get lucky on the first try) you have to liquidate them. Word gets out some guy got his wallet hacked by someone using an ASIC or whatever and hacking the keys to transfer the Bitcoins out and good luck selling your ill gotten gains. No one will want to buy bitcoins.

Cracking an address takes more time than the life of the universe. Good luck  Wink

Isn't the private key like 256 Bit? But then again, you might be lucky.

Yes, please waste your time and resources on trying to do the (almost) impossible.

It would take 100 billion years, constantly using all the power of the sun, for you to even have a remote chance at stumbling upon ONE address that has already been created before.  Never mind whether that address has anything in it.

The search for nonces changes every 10 minutes.  An address with a lot of coin might be in cold storage and you might be able to search for months uninterrupted and your reward might be very high.
It's about 3,513,612,269,993,879,528,303,320,959,297,632,275,254,396,583,673,016,120,886,766 times harder to crack an address than to find a nonce that mines a block. Given that mining a block yields 25 bitcoins and cracking an address yields at most 21,000,000 that means that even if you crack the address that holds every single bitcoin that will ever exist, it's still 4,182,871,749,992,713,724,170,620,189,640,038,422,921,900,694,848,828,715 times worse than finding a nonce.

Ok, what calculator do you use for those huge numbers that doesn't auto-convert to scientific notation?

Yeah, my numbers are off by a factor of 79,228,162,514,264,337,593,543,950,336. Finding another key with the same hash is sufficient. (Third time I've made that mistake.)

Joelkatz,  thank you very much for exactly th answer I was looking for.  I am not into stealing but I am into understanding why this will entire bitsphere will work.

Apparently i still don't understand mining.  Isn't mining finding the nonce for the next block and that nonce is dependent on the previous block?  So as soon as there is a new block, nonce searching has to start all over?

Yes, it "starts over" after each block.  But you have just as much chance at finding a block with the first nonce that you search as you do with the last nonce.

Here is a great resource about mining on WeUseCoins.com

Yup, but there is no "start over" in the sense that you work toward something, to find a nonce you just try tons of hashes, one of them can be the right one, and you can try billions of hashes per second.

It is Start Over in the sense that the billions of nonces that didn't work for one block might work for the next block, you may as well retry all the nonces that failed.

Yes, the nonce starts at 1 again.
