Verwirrt über Passphrase

Ich habe in anderen Threads gelesen, dass, wenn eine Passphrase über den Ledger hinzugefügt wird, ein Hacker die 24-Wort-Seed-Phrase UND die erstellte Passphrase haben muss, um Zugang zu den Assets zu erhalten. Mein bisheriges Verständnis war, dass die Seed-Phrase Teil der Blockchain ist und man von jeder Wallet mit einer Seed-Phrase auf seine Kryptowährungen zugreifen kann.

Nebenbemerkung: Ich habe vor einem Monat einen Ledger gekauft und bin immer noch mehr als paranoid, was den Verlust von Vermögenswerten angeht, selbst wenn ich die Seed-Phrase aufgeschrieben habe, nie online war und in einem verschlossenen Safe lag. Und ich habe keine bösartigen Verträge unterzeichnet. Versuchen, den Geist zu beruhigen und auf der Suche nach einigen Leitlinien.

So when you add a passphrase to your recovery phrase, you essentially create an entirely new seed from which accounts are derived. Because of how hierarchical deterministic derivation works, anyone with the 24 words can derive all accounts linked to those 24 words, anyone with the 24 words + passphrase can also derive the accounts linked to the passphrase.

Changing the input of the hashing function, namely by adding a passphrase, changes the output of the function entirely.

Tldr: 24 words + passphrase act like an entirely new set of 24 words with respect to account derivation. Someone with your 24 words has no way of knowing whether you have passphrase accounts associated with those 24 words.

Edit: Recovery Phrases and account derivation are difficult to wrap their head around, but the aha! Moment when you do is super worth it. If you want to stop by one of our Friday AMAs I’d love to chat with you about it. Otherwise post whatever questions you may have in the thread!

I’m not sure if you are good at math and have heard of the Fibonacci sequence, but it is a series where the first 2 entries are both 1 and then each new number in the series is the sum of the previous 2. So…

1,1,2,3,5,8,13,21,… and so on forever.

the 2 first entries in the sequence can be though of as the seeds because they are needed to start using the real equation for the terms of the series. Each new pair of initial conditions (first pair of seed terms) will generate a deterministic series. New seeds make a new series but the same seeds will always produce the same series.

Well, your 24 words are the randomly generated seeds that salt the equation to produce a deterministic output. Each specific set of “seeds” produce the same deterministic output. Having a passphrase is just a 25th word to add to the randomness.
