an implementation of bad node that denies every blocks generated by pure nodes.

How it works

// List of bad friends.
private HashSet<string> badNodeAddrs = new HashSet<string>();
        
protected override void OnNewBlock(Peer sender, PktBroadcastNewBlock pkt)
{
  // Check the block is mined by alias
  if (badNodeAddrs.Contains(pkt.block.minerAddr) == false) return;

  base.OnNewBlock(sender, pkt);
}
