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.
