Record GrowNYC supply chain transactions on the blockchain and have them visualized on a google map in real time. Use chainpoint proofs to prove that a particular item/product was at a location at a given point in time. (GrowNYC, Chainpoint)

Biggest problems: Traceability - being able to answer questions such as where did this case of strawberries come from. Manual work - a lot of manual effort is spent recording and piecing together history for particular items.

Use the Tierion API to perform delivery validation. I should be able to query on a particular item and get a linked list of that items history that is validated on Tierion and the BTC blockchain.
