I’m currious how data is copied around without overloading nodes. It seems like it may also have the problem of some people don’t see some comments on a specific post, which leads to confusing conversations
I don't fully understand how all that works. I know there is some nips about finding out where users usually post stuff too. But i have noticed in some clients i'll see stuff in chat thats not in other's because the relays are different.
That is just the trade off you get for decentralization though
No private keys are sacred in nostr. Just like Bitcoin. You lose it you have to tell all your followers to re follow the new public key .
