Problem: A sells some physical thing called X to B. How to somehow prove to a third party C that B bought X from A ?
- Note that I am fully aware of many supply chain based on blockchain out there, including Vechain, Blockverify, WaBi etc. I don't want to use them at this phase because they are either complex or not economically feasible.
- At this phase we don't need to discuss about attaching RFID or QR code to physical goods.

Hi, why not consider to use HyperLedger wich is open source and free ( so no economic constraints), unless you have a very specific need wich require development from scratch Regards,
