I understand that addresses do not have to connect to the bitcoin network/blockchain in order to be valid addresses, but I am mainly wondering about what can be seen in the blockchain if that address has never connected to the network.
So given this scenario
AddressA sends 1 bitcoin to cold AddressB. AddressB has never been online.
There will be a transaction id for this. But what would a site like blockchain.info show for the balance of AddressB?
Would it still be able to aggregate all of the transaction that go to AddressB to show a balance for AddressB?
