Hypothetical question on lost coins/transfers
I think not. I think that when a client considers a block bad it gets the transactions that were in it and rebroadcasts them or puts them in a block themselves.
That’s right. You don’t need to be re-broadcasting your transactions for it to work.
When any node disconnects a fork, it dumps all the transactions from the fork back into the transaction pool to add to the new chain. The entire network is making sure to re-integrate your transactions again. All you should see is that your number of confirmations starts over from 0.
In some types of forks, your transaction would have gotten into both forks already, so you’re already good either way.
