Sigh, the fudders are really strong.  Someone that has 3 post total and the last post in OVER a month is about Centra....

But to answer your questions.
If you were in the Centra Slack, you would know:
- White paper is being updated.  There are new projects added to the roadmap
- Someone to handle social media was hired so forum is down temporarily

Check the links I posted above about Centra to get a better idea of their products.  Shipping is in less than a month.
