user11366: If major Internet connections are broken, what happens to BitCoin transactions?
For example, the Internet connection is broken between three major areas (North America, Europa, and Asia) for a couple of hours, and these three regions become isolated to each other.
Can we still do bitcoin transactions inside these three regions?

user85: Bitcoin would be catastrophically broken under such a scenario. Transactions could accumulate any number of confirmations and then unconfirm if blocks leak from one region to another. Bitcoin fails horribly if you are not either connected to none of the hashing power or connected to most of the hashing power. Anywhere in-between, for extended times, is catastrophe.
This is actually not particularly difficult to fix, but nobody seems particularly interested in fixing it.
