We have an idea to build an ecosystem for delivery, including: sales management - shipping - storage, creating a closed loop to eliminate the participating of third party to optimizate cost for the whole system. Which blockchain we should use, the blockchain that we build ourselves or another available blockchain?
If I understood your problem right, then you may need your own blockchain, where new "objects" (products, not coins) are added into the system when they are needed, the "spending" is actually a transition to another state (a "wallet" can be a certain truck that does the shipping and when the product reaches the destination that "wallet" will "spend" to the warehouse) and so on.
Of course, I may have gotten everything wrong.
It sounds like an interesting project, good luck!
