Can a blockchain offer transparency to a humanitarian aid supply chain? I am located in a middle eastern country which is in desperate need of humanitarian aid.  

I have contacts in western countries who are willing to call upon their independent donor network to provide significant amounts of aid in the form of physical assets (not financial). However there is concern over the transparency of the supply chain on the receiving end, as it is typically the case that physical assets tend to disappear in the region, whether they pass through official channels or not.

Therefore, I am interested to know if a blockchain could be used to provide transparency to this humanitarian aid supply chain.

This would greatly increase the confidence of donors and thereby lead to greater amounts of aid being delivered where it is needed.

I have read that blockchain can be used for physical assets and can increase the transparency of a supply chain from a consumer perspective of provedance, but this is the opposite way around, where it is the supplier wanting to have transparency in regards to the beneficiaries of the physical assets.

Furthermore, if this is achievable, I would also be interested to learn how to establish such a blockchain ie what resources or technical knowledge is required or where can these be obtained.

Thank you in advance for any input.

It would largely function by pictures I would imagine. Let's say, for example, each crate of goods had a QR code, EDIT: with the private key known only to the supplier. 

So the supplier gets these QR codes(public keys) , slaps them on the crates and sends the crates on thier way. The receiving end then must provide not only a video of those crates being opened in a food distribution center, but the video must include the QR codes in the footage. Then the supplier will know thier goods have not been hijacked, particularly if the video includes the goods being handed out on camera.

Those videos can then be published along with the QR codes for external verification on a blockchain.
