For the record, peer discovery is irrelevant to consensus in Byteball.  Even if Sybiled, a node cannot select a wrong branch, by design.  The worst that can happen to a node while it is Sybiled, is that the node will stay stuck at some old point on the DAG, as if it were offline.  CfB if you want to reply, IOTA thread is not the best place for in-depth discussion of Byteball, post to https://bitcointalk.org/index.php?topic=1608859.0.
