Wie kann eine Seedphrase, die in einem “Offline”-Ledger erstellt wurde, in einem anderen “Offline”-Ledger “wiederhergestellt” werden? Ist das nicht ein Sicherheitsproblem?

So seltsam es erscheinen mag, wie kann ein Ledger Seedphrase, die in der gesicherten Element gespeichert ist, kann Ihre Wallet in einem anderen neuen Ledger sicheres Element wiederherstellen, dass Ihr Seed ist nur von Ihnen wissen, und Sie nie eingegeben es online. Das bedeutet für mich entweder, dass das Ledger mit dem Internet verbunden ist, wenn Sie es einführen und Ihre Wallet durch die Eingabe Ihres Seeds erkennt, ähnlich wie bei Hot Wallets, oder dass jemand wie Ledger selbst es speichert oder über die interne App oder über ihre Ledger Live App Zugriff darauf hat. Ist das nicht ein Sicherheitsproblem? Ich meine, ich dachte gerade daran, wenn gerade jetzt… kann Bullshit klingen, aber ich möchte Ihre nehmen hören

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). -

Your seed phrase is your private key. When you create your wallet you are creating an address that lives on the blockchain. So when you import your seed phrase into any wallet, you are just accessing your account(s) that live on the blockchain. Think of it as your mailbox that has a lock on it. Your seedphrase is the key to open that lock.

It’s because the accounts and addresses are all derived from the 24 word recovery phrase generated at the time that you set up the device.
the specific BIP39 mnemonic standard, which the 24 word recovery phrase is created from – is technically impossible to crack (even with intense computational brute forcing).
also the device can generate a virtually-infinite amount of 24 word recovery phrases, and so this process isn’t 1 an done. you don’t use a ledger once then throw it away if it’s compromised. u can reset it, generate a new 24 word recovery phrase, and the device will literally be brand new and absolutely secure.
this is all based in cryptography, math, RNG, and people who have dedicated their lives to designing these systems (long before the existence of hardware wallets, and even cryptocurrency).
with private keys, we’re talking about cryptographic research dating back decades and decades and decades. I wouldn’t be worried : )
