Since I'm not sure exactly how this works on a technical level right now (might have slipped my memory): is the mining software / firmware used communicated through Stratum v2 and / or could it be spoofed? How do you make sure that someone pointing hashpower to your pool is running a tested / 'known working' software stack?

Kano has made his opinion of Stratum v2 well known and safe to say it will be a mighty cold day in hell before he uses it. As for how he determines if the miner is running a hacked version of cgminer (which are quickly kicked off) vs accepted OEM, Braiins, BGminer or Bitfury firmware - trade secret...
