I've tried to find a way. It seems like nobody knows. There was a way to do it 3 years ago (
https://github.com/brian112358/nevermore-miner/wiki/Solo-mining) but this no longer works as there is a new algorithm. This method also doesn't seem to work with newer miners because there isn't equivalent commands for the newer miners (at least the ones I'm using).
I know how to "solo-mine" using a solo-mining pool, but that's not what I'm looking for. I want to know how to do it 100% solo. Does anyone know of a way to do it?
