So the internet, at least in your location, goes down. Your cryptocurrency is now completely useless, and therefore worthless. Without whole-network consensus blocks can't be validated, forks occur, situation gets rapidly FUBAR. Would it be possible, if there was just one Masternode locally to validate transactions, to build a method of having those 'offline' (as far as the rest of the blockchain is concerned, because your town is currently offline remember) transactions get smoothly integrated back into the larger network when connectivity to the internet-at-large is restored? I'm talking about mesh networking for blockchains, using Masternodes as local 'authorities.' Can we make Darkcoin resilient by using Masternodes in such a scenario? eg, plug your MN into one of these http://piratebox.cc/ and carry on doing business. Or outright integrate MNs with routers, have MNs as appliances?
