What is FLAX? Or XFX?
It’s a clone of Chia with some alterations. Most notably no prefarm.
The only relation with Chia is that it is based on a copy of the code used for Chia.
There are many copies like that out already.
Had to have its own plots though I assume right?
No, you can use the same plots you have for Chia and farm at the same time.
Ohh dang! Noice! 20 character
