To me it looks like the project has *only* one developer (not one core developer, but only one developer), as it can be inferred from the GitHub page:
https://github.com/216k155/lux/graphs/contributorsI wouldn't count a dozen commits as serious, long-term contribution.
This is a bit concerning, given that there've been constant references to a "team", but it seems to me it's a dev team of one. Good luck to the project regardless, if it's indeed not a scam.
