The modern food chain is very large and complex. There are numerous actors involved that influence the making of the product and its delivery, whether directly or indirectly.

We'll be looking at this modern food production process, learning about the challenges of the modern chain and proposing a new one based on blockchain and IoT:

The business process shown in the preceding diagram is a simplified version of the modern food chain. The chain can be much bigger than the one represented here. For example, many supermarkets have their own distribution centers. However, since our main goal is simplification, we didn't represent other factors, such as ports and customs. 

For our use case, we'll seek to account for the product from the time it's delivered to the manufacturer. This product could be any item, but we'll use chicken drumsticks for our example.

The asset to be managed in our chain will be a box full of chicken drumsticks, and our other asset will be a pallet full of boxes containing chicken drumsticks. In the food chain, we'll be looking at the processes of the following actors: the manufacturer, distribution center, and retailers. 

As stated previously, there are a lot of actors in the modern food chain. Remember that we're following a more simplified process, not necessarily the actual process followed in real life. Our goal Here's understanding how IoT and blockchain can help the parties and processes inside the food chain.
