Antwort auf: Wie kann eine Seedphrase, die in einem „Offline“-Ledger erstellt wurde, in einem anderen „Offline“-Ledger „wiederhergestellt“ werden? Ist das nicht ein Sicherheitsproblem?
If you have two calculators and you put the same mathematics equation into both of them, they get the same answer. This is because the rules of mathematics are programmed into both calculators already. It does not mean your calculators have access to the internet, or that the equation results were stored anywhere.
Your Ledgers are built the same way, they are programmed with a set of mathematics rules & algorithms (this specific one is known as BIP-39) to calculate your wallet addresses based on input (your seed phrase).
It is notable to mention that the concept of a „wallet“ is actually just an abstraction to make this easier to understand for humans. Your crypto lives on the blockchain, not „in a wallet“. To move your crypto, you need to prove that you own the address. The BIP-39 algorithm generates a repeatable list of addresses & private keys (which is used to prove ownership of the address).
So, with this mathematics algorithm, you can find all of the associated addresses – this is what makes your „wallet“. Just like your calculator, your Ledgers can do this without any internet access, as long as you give them the same equation (your seed phrase).
After you know the addresses, the LedgerLive app can look up on the internet what the balance of each address is – and this is how it knows your balance.
What this means is your wallet is never „being recognized“. Your seed phrase **is** your wallet (or rather, a list of addresses).
