No offense, but you sound like someone who doesn't really understand the technology. A TX record is signed, which proves that only I wrote it. It does not immediately have to become part of the "consensus ledger" i.e. blockchain. All I have to do is not spend the same money twice, and I can keep local records. Once the net comes back up, everyone can enter in their TX records manually and let the network figure out the rest. Any attempts to spend the same money twice would be prevented unless you somehow managed to spend from the same wallet in both fractions of the bitcoin network, which seems like it would be hard to pull off.
