Yeap as stated in the whitepaper the zeroCT part is written by the navcoin team. It has been iterated multiple times in the whitepaper and credit has been given accordingly.
Yeah the website is copied from navcoin until we can get a webdeveloper to create a new one for us. Im not removing it because i dont have the time to create a new website and webdev isnt my thing. will change it once we get someone willing to do it.
