Yes, as I mentioned above, I see their Github account repos. However, all the repos there are either Github pages, white papers, or forks of Ethereum projects. They've evidently deleted or made private the https://github.com/project-douglas/eris https://github.com/project-douglas/eris repo whose license is referred to the in white paper. Presumably, that's the repo they refer to when they describe this accomplishment in the white paper: "...Eris, a platform which allows developers and users to deploy consensus driven applications which rely on decentralized architecture and a consensus driven blockchain database backend."
