Hy,
atm i do learn alot about Bitcoin and the underlying blockchain technologoy.
What i do not understand how a offline wallet is generated. Ok, of course i have read the basic howtos, so in generell i know how it is done, but i do miss some points.
Cause it is offline, how is it guaranteed noone else is generating the same offline address as my offline wallet?
I have no chance to check if that address was ever or not, if the computer i do use to create that wallett priv key is offline.
Maybesome can examine how that problem is solved or handled?
Thanks in advance and excuse my english..

There are dozens of threads like this one:

Just search for "key collision" in the search
But, in short, it's possible that 2 people generate exactly the same private key, but if the RNG that is being used isn't flawed, chances are astronomically small... Like: "it isn't going to happen in a million years"
