Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

I see , thanks then and I assume that It should be the same for verifying since you don't even need a private key for verifying signed message unlike signing them.

Correct, signing and verification happen locally and no blockchain data is needed.
Im not really here, its just your imagination.
