How do paper or offline wallets work? I am reading the monero guide on securely storing monero (https://www.getmonero.org/resources/user-guides/securely_purchase.html) and you are creating a wallet (along with seed, receiving address, watch and spend keys) without being connected to the internet or blockchain.
This would imply that your wallet and seed have already been created and are just floating in the blockchain awaiting a deposit? Otherwise how does an offline script create a wallet that you can use?
Just when I thought I had my head around crypto I read this and it all goes pear shaped.
