We’ve just made our contracts, our zkSNARK circuits, and a lightly-modified reference implementation of the frontend webclient available on Github. You can find the repository here.
The frontend client will automatically connect to the core contracts on Ropsten. Follow the instructions in the README.md to get set up.
Dark Forest v0.3 will end on midnight EDT, Saturday 8/15/20. For updates, follow us on Twitter or join us on Telegram.
