A new app called OriginTrail shows how the blockchain will be used to track food and medications as they make their way through the supply chain. 

This will allow you to be sure that the product was stored at appropriate temperatures, and moved safely.

Coins that are meant to track supply chains include **Vechain**, **Waltonchain**, and **Ambrosus**.
