If Avalanche can be applied to BCH, that would be awesome. However, I have to be honest I have yet to understand how this is a secure method. Probably I'm still missing some bits and pieces.
Apparently it's Naomi's video with Pacia that enlightened me. I now have a clearer picture of what Avalanche is and how it works.
AFAIK, anti-sybil method for Avalanche hasn't been chosed yet.
