Frantz Our app is now a cabbage-receiving mechanism but it works - quite nicely actually. We have a smart contract with a JS library, an API to store Bill of Ladings and a webapp that can process cases that are attached to the Bill

Starting was easy: we wanted to do something with Blockchains, and the Mercedes trucks seemed pretty cool as well. A few of us have worked in warehouses and know about one of the most annoying things there: confirming that whatever is on the Bill of Lading (a big list) is actually in the truck.

It was pretty easy to figure out the problem we want to solve from there: Use IoT data and Blockchain to make accepting shipments in a warehouse easier

It took us a couple of hours to figure out how Blockchains work (and some more time to find the update feature on Devpost).

This is our tech stack:

a Django API to store the Bill of Lading the attached instances of our smart contract a Javascript Frontend to show the Bill of Lading to the person getting shipments off the truck a smart contract in Ethereum

It is hour 77. There is 40 of us left. Food stocks are low and somebody just invited EVERYBODY to join their team.

Also, why is there no salty popcorn?!

Setting it up locally was a bit tricky but we have a smart contract! It models a buyer-seller relationship in Solidity where a Bill of Lading can consist of several cases, each with a value. The buyer adds funds to the contract that are released to the seller when the case is "received".

We also decided to add truck data to the API: a case on a BoL can only be received if the cases have been transported over a certain temperature - we're dealing with fire cabbage here.

Turns out smart contracts are pretty complicated!
