If I am not mistaken, I believe Zcash supports Ethash-4G mining hashing algorithim?

If this is the case, does anyone know a good foss software which supports Ethash-4G and you can import it as a library to your code?

The mining algorithm for Zcash is equihash 144,5. Would be 6G I suppose

Is this open source?

Yes the code is freely available unless you mean something different by ‘open source’

Someone please correct me, but I believe zcash uses equihash 200,9. I think BTG uses equihash 144,5 for example.

Yeah I think you’re right sorry about that, Ycash is 192,7 I remember that, idk why I said 144,5
