There are many but not many legit ones.
I have been doing a lot of research myself and i have found very few for the next month.
Enkidu is one among them and i highly recommend this project! Their whitepapers, blogposts are legit and also the daily vlog on youtube channel is very informative. They have a talented team putting a lot of quality time on this project. Check their telegram group too..
