This is where I'm starting on work for a system called "Govern" which provides a way for delegate-based representative democracy, and potentially complete, direct democracy. It's mostly just dreams and stuff right now, but please feel free reach out and provide feedback!
This is a monorepo, and more information on the components can be found in their individual directories, which each have README files of their own.
The project is being tracked and managed publicly on Trello.
Check out the CONTRIBUTING doc.
