What was originally paid for was a new coin, being that said I couldn't tell you whether what we actually received was a clone or from scratch.. All I can remember is that the code was working before. The last few edits I made were changing the genesis block.
I skimmed through the code blocks,there is a higher chance that the code isn't written from scratch.Have you commented out the changes ? Just downloaded the repo,let me have a look.Compilation failing with any errors for now ?
