The problem TU-Troquer solves

Our concept is to provide a platform for college students to buy handwritten notes in return for coins. TU-Troquer will help you avoid the last-minute stress of looking for your notes and can even reward you with vouchers if you submit your notes.
Finding notes have never been easier with TU-Troquer. It serves a dual purpose by supplying students with handwritten notes and rewarding students who submit their notes with digital coins that can be traded for vouchers from local businesses. Our concept eliminates the stress of trying to find genuine notes at the last minute.

Challenges we ran into

We tried to use blockchain for our project and faced difficulties while assembling its code. We didn't know much about Solidity and thus it was really problematic to solve it.
