By default, when entering #Nymchat it assigns you a keypair and this keypair persists until you logout or clear browser cache. However, there is a feature in settings that allowed generating a new keypair if you reloaded the app, instead of keeping the persistent one. Now, a new "hardcore" option has been added that rolls the keypair after every sent message. So, you are assigned a new identity after every sent message, where your pubkey is different each time.
Interesting... something nuked my btc core node with too many rpc connections and now my db keeps locking... could knotzis be trying to take down core nodes? Or, is this somewhat common and i just need to tune the available workers/threads to higher amount?
