p2p id should be regenerated at node start #3786

Open pigmej opened 2 years ago

p2p id should be regenerated at node start otherwise, the potential attacker can attack a given ID explicitly.

During discussions, it was commonly agreed that we should regenerate that ID on node start to make this set of attacks harder.

we definitely can't do it for bootnodes, as id is a part of bootnode url

i think it was @noamnelke concern that using the same p2p identity leaks metadata, and someone can find the connection between p2p id and smesher id by monitoring traffic patterns.

We could potentially have it done "post genesis" to increase the network security.
