"The first thing that happens is nothing. Your smartphone stays black while you swipe at it and press the various buttons. Has the battery gone flat? You could have sworn you left the house with a full charge. Now you start to wonder how you’ll get your car out of the parking structure without a working mobile. That thought hadn’t occurred to you before.
It’s the least of your worries.
Still fussing with your smartphone, you gradually begin to realise you’re not the only one having this problem. In fact, it would seem that everyone waiting at the pick-up area is in various stages of agitation with their own smartphones. Some are pressing odd combinations of buttons, trying to reset the little beasties. Others, who have clearly had rough days now made worse, start to swear at their dead screens, as if cursing might shock them into life.
It’s weird, and almost a bit funny. For a brief moment.
The first smashing can be felt more than heard, a subsonic strike something like a vast drumhead being struck with a metre-wide mallet, but so quick, you barely even notice it until it’s over. The second one, however, isn’t far behind, and it’s a bit louder. That second thump gives away its location — whatever it was seems to be happening quite close by — in the direction of the parking structure.
At just this moment a car cruises through the pick-up zone at full speed, barreling along at least 100 kmh. It’s only because of some very fast reactions that no one gets hurt as it passes by. As it zooms past, you notice there’s no one behind the wheel.
Before you have any time to process that, another huge thump nearby causes a section of the barrier wall of an upper floor of the concrete parking structure to shear off. A pile of rubble falls to the ground not very far away from you."
It's pretty well written, but somewhat unrealistic from technical standpoint.
The first part is OK (except author forgot about "fire exit" laws, so the mall doors would not be locked)
The second part, the one which describes "consensus" system from technical standpoint, is wrong. The protection does not work this way. As in, it can surely be implemented, but it has no benefits that author claims and would not protect from stuxnet-like "viruses" (sic!) at all.
The third part, where the bitcoin is mentioned, is outright science fiction.
