what algo? how to run a node? running node has block rewards?
The algo is identical to Bitcoin PoW.
This is an open community project and the codebase is a fork of Bitcoin Core. Any contributer interested in writing PRs to implement the design paper is welcome to. I'll update the community once the implementation is ready for execution and mining and you can of course follow the GitHub.
Block rewards are similar to Bitcoin but with a bootstrap period of expedited mining.
See the design paper (#9 Bootstrap):
