Hi, Validators,
We have identified some rogue
peers sending out consensus messages signed with non-active blskeys on harmony mainnet.
Those nodes will be blocked in the network later once we implemented the block list feature as described here (https://talk.harmony.one/t/nodes-sending-invalid-p2p-messages-to-the-network/786)
It may occur if you are running legacy version of node program prior to v2.1.9.
For now, please do a self check on your node or backup node, and taking them offline if they are in the rogue
peer list.
