The Xenio blockchain code is available on github: https://github.com/xenioplatform/go-xenio/

Oren's code is...well, it's never been available anywhere, actually, because it never existed. Like so many ICOs before it, they tried raising money before they actually put out any code at all. Those are the scam projects. Vaporware. Empty promises.

Xenio has code. Good code. And it's being updated practically daily.
