Hello,
I'm studying at the Wroclaw University of Technology. I'd like to write a thesis about cryptocurrency. I want to make a DAPP. I think about Ethereum/Ethereum Classic or Lisk. I must precisely describe my thesis. This also must include investigative part. Could anyone help me? Maybe someone make something like that?
