The problem we are trying to solve is that of tracking assets of high importance such as nuclear waste, weapons and medicine.
The way we tackle this problem is by keeping track of the payload carrier on the blockchain. We apply some cryptographic scheme using layering encryption (similar to the onion router) that was developed over this hackathon and is still being improved to ensure that each carrier only knows where to deliver the packet and not the end destination.
At the same time, using satellite data we can collect information about the location and environment of the payload. This can be used to detect deviations from the path as well as whether the packet has been through weather conditions that are not acceptable.
