I have a question about this topic, so, better post it here than start a new topic.
If we turn off all the miners and only leave 1 pc with cpuminer running will the 10 minutes block stay, or since the complexity is a lot bigger than the mining power the blocks will have a huge delay?
if you'd do this, the difficulty would still be sky-high, and the cpu miner would probably take hundreds of years (if not more) to solve a single block... Since a diff retarget only happens every 2016 blocks (and if i'm remembering correctly, the diff retarget is also limited), it would take thousands of years untill the time between 2 blocks would be 10 minutes again.
