Creating paper wallet while offline

[CazzataMalanga]

The wallet creators usually tell you to create your wallet while offline. How is this possible without a connection to the internet?
How can the blockchain know about the existance of my public and private address without any online communication? I'm confused.

thx

Blockchains doesn't store addresses directly. Blockchains based on Bitcoin UTXO model store transactions and transactions only. Transaction has inputs (source of funds) and outputs (destination of funds). Each output has locking script that specify conditions that has to be met in order to spent that output in the future. Each input spends output from previous previous transaction and contains an unlocking scripts that satisfies a condition placed on that output by its locking script. Locking scripts might among other things specify an address of a "recipient". But there is no such thing as master list of all addresses, at least not on a database level.

Save the link as a desktop icon, turn off wifi and then create the wallet. Its best to do this on an airgapped computer. Check this link out for some more help https://en.bitcoin.it/wiki/How_to_set_up_a_secure_offline_savings_wallet

I want to understand the background of this:

Once I've created my paper wallet offline (with a generator) I go back online and all of a sudden there's a new empty wallet "floating" around somewhere just waiting to recieve coins.

How is this possible when I was offline the whole time during the creation of the wallet? There was no communication with anything on the internet.

The Blockchain records only the transactions and the new coins created by the miners. If you type one by one all the addresses that can ever exist, it will return 0 or a number (the existing amount of coins). When you create an address online or offline the blockchain doesn't know it.
If you transfer a coin to this address then it will record it and will return the transferred value or the sum of the address.
I hope I have helped.
