Project for #BIOTS2018: gamify recycling using the Blockchain & AI.

Summary

We introduce a gamified version of everyday's recycling which incentivises ecological behaviour by a lottery. For this, we developped an Android App that allows the user to scan, i.e. recycle, items, thus earning a direct return (the usual deposit) and also tokens for a raffle. Thus, the consumer has a direct reward, but also the chance on a even higher one which naturally triggers ecological behaviour.

The Blockchain is used as immutable backend for the lottery. We use Oraclize as trusted backend for random choices. Image recognition is possible thanks to the Microsoft Cognitive Services. Our repository consists of the Android frontend (./app), the Ethereum Smart Contract (./contracts) and helper libraries (./java).
