Can you imagine if some mad scientist pointed his quantum computer at bitcoin, solved all the blocks in a split second at the beginning of a new difficulty re-target, then unplugged, leaving the difficulty at 10 billion.

Would take the network a year to solve the next 2016 blocks to re-target to normal again  Shocked

Difficulty increase is limited to 4X.

If the scientist were not so mad (or insane) and just solved blocks, but submitted them every 9 minutes (or faster than the average time, but not the next minute), he'd be mining blocks for a long time. And if he's not very greedy, he'd only get half of the block rewards per day.

He could hide in a mining pool, or just go solo.

WHAT IS SO SCARY IS NEXT YEAR when 1 terahash will only produce 500,000 USD because of the block split to 25 coins.

i think the difficulty will go down, because a lot of people will stop mining because of the cut. So its properly still more than 500,000 USD Smiley

I found it at https://en.bitcoin.it/wiki/Target
"A single retarget never changes the target by more than a factor of 4 either way to prevent large changes in difficulty. "
