does start9 support stratum v2? tried my bitaxe and it keeps rebooting, changed it back to v1 and it works fine.
Start9 is the entity that develops the home server operating system called StartOS. Start9 doesn’t “support” Stratum v2. StartOS does nothing other than support the ability to run software packaged for StartOS.
Whatever you’re doing with your Bitaxe has nothing to do with StartOS and everything to do with whatever you have installed on StartOS to connect your BitAxe to.
My guess is either Public Pool or Datum, but you don’t say. If either of those, the answer is no, they don’t support Stratum v2. Again, nothing to do with Start9 supporting anything.
