Hi, I’ve been thinking about an attack to censor specific validators, and was wondering if it is viable, and if so, whether it could be avoided.
My thoughts are that a malicious user could create several modified full nodes. Those full nodes would only gossip the addresses of other malicious full nodes. Also those full nodes would never gossip votes or proposals from a selected validator. By doing so, if there are enough malicious full nodes, messages of a certain validator would maybe not reach all other validators.
So I was wondering if this would be viable. I was hoping for some other thoughts. And maybe I got it completely wrong.
