That issue has to be solved only after the Silktorrent as a software project is complete.
The Ability to Trade Physical Goods is a Fundamental Requirement
The thing to keep in mind with that project is that if one were to create a simple, plain, screw in stead of a computer system, then one would probably fail to do it without depending on others, without trading, because metal for the screw either has to come from something recycled or has to be bought from somebody else, unless one starts to think, how to mine iron ore and process it, which is inaccessibly huge task and requires huge investments to mining equipment or travelling. Therefore the production of custom hardware depends on free movement of physical goods, which can be effectively limited, as the Soviet Union era demonstrated. The 2. World War and Soviet Union era also demonstrated that it is possible to hide/store equipment, weapons, books, blue-black-white flags to areas, that are not bombed to the ground. It is a FACT that by mere chance some of those items, including functional firearms, survived even while being stored at people's homes. Therefore before starting to develop any doomsday-custom-hardware, "warm summers of open trade-routes" must be used for storing electronic equipment for surviving "foodless frozen winters of closed trade-routes". Electronic equipment has to be literally stored in refrigerators to slow down the diffusion within the components and at some point they have to be replaced with new batches, both, for technical upgrade reasons and for replacing probably "more diffused" components with "less diffused" components. To do that economically the old equipment must be usable with modern software, which means that the new software has to be very efficient to be able to run on the old hardware. The first candidates for storing are various Raspberry Pi like computers.
After the storage part has been solved, the next project is long distance drones that are capable of flying undetected by any military equipment. The cargo of those drones is small electronic equipment, microchips, money. The money transfer is necessary even during peace time, because the Supermafia always gets the majority of votes from slackers and otherwise parasites, who do not want to develop their own business and just jell that "the Government" should rob the hardworking people and redistribute considerable percentage of the robbed assets to the slackers. Unfortunately the top executives of the banks are psychopathic poodles, who do not fight for the rights of banks to keep their client's account details secret, nor do they do hardly anything to make it possible to use the services of the banks for online trade without some absolute nonsense legal burdens. The 2016 banking sector in Europe is just plain disgusting. Crypto-currency is often times useless, because it can not be exchanged for the currency that is used locally for paying for basic living expenses like electricity, food, utilities. In the case of money the drones should include a money burning equipment to be able to burn the money and dump the un-burnable bits prior capture by the Supermafia. To minimize losses at transportation, money can be transferred in parts. The Supermafia will, obviously, "ban"(a term of newspeak) those drones, just like they have "banned" barrels that burn gunpowder. To avoid causing material harm to the airline industry and to avoid endangering the lives of airline passengers the drones have to fly below the heights that passenger airliners use. They must also avoid hitting any ships and sails of sailing boats. The body of the drones must be blunt and soft enough to make sure that if the drone were to hit someone straight to the region of the eyes, no eye damage is done.
Multi-CPU-machines from Microcontrollers or Cheap CPLD-s and FPGA-s
Each MCU runs a virtual machine that simulates a CPU-core or some other block of a CPU. The simulated multi-core-CPU has also memory management functionality. Pascal programs are compiled for the simulated CPU by using a compiler that might have custom optimizations in addition to the classical custom back end. The key phrases are: GPU architecture, Systolic Processors, Wavefront Processors.
What is needed is devices for creating individual prototype electronics chips. Scanning UV-beam based "masking" technology has been used in industry laboratories for decades for creating prototypes. Probably the initial bill of material contains: UV-LED, piezoelectric components from some piezoelectric microphones for precision-movement of the beam, some passive sound barrier (The University of Tartu Institute of Physics cellar room for using the various atomic microscopes is a source of inspiration), may be, later, some active sound barrier.
