Wiedererlangung einer verlorenen/gestohlenen/beschädigten Hard Wallet. Alles, was Sie brauchen, ist die 12/24 Seed Phrase?!?

Hier ist etwas, das ich nicht verstehe. Ich schaue mir Tutorial-Videos an, wie man seine Hardware-Geldbörse im Falle eines Diebstahls, einer Beschädigung usw. wiederherstellen kann.
Alle sagen, dass alles, was Sie brauchen, um Ihre Wallet wiederherzustellen, Ihre 12 (oder 24) Wort-Seed-Phrase ist.
Sie nehmen also eine brandneue Wallet und geben die 12 oder 24 Wörter ein, und schon haben sie wieder Zugriff auf ihre Kryptowährung.
Das verwirrt mich….
Kann jemand nicht einfach eine neue Hardware-Wallet nehmen und immer wieder beliebige 12 oder 24 Wörter eingeben, bis sie schließlich in der Wallet von jemandem landen?
Man wird nicht wissen, wem es gehört…. und man wird nicht in der Lage sein, die Wallet einer bestimmten Person zu finden…., aber wenn man einfach 12 oder 24 Wörter eingibt… wird man schließlich in der Wallet von jemandem landen. Oder?Wie….das scheint mir sehr unsicher zu sein.
Ich würde mich viel besser fühlen, wenn das Gerät sagen würde:…. zuerst den öffentlichen Schlüssel eingeben….. und dann die Seed-Phrase des privaten Schlüssels mit 12/24 Wörtern eingeben. In diesem Szenario ist es so gut wie unmöglich, weil man gezwungen ist, den öffentlichen und den privaten Schlüssel abzugleichen.
Was übersehe ich hier?

> but if you just keep throwing 12 or 24 words in… eventually you will land in someone’s wallet. Right?
Exactly right!
But the “eventually” is “if you keep at it for a million years”.
Like the monkey banging at a typewriter, “eventually” by pure chance will type up Shakespeare’s complete works. That’s what the math says, but it’s never gonna happen in the real world.

Instead of going through entering all those seeds manually, here’s a nice list of every private key, you can just use it instead…
2^160 (above) or 2^256 are both unimaginably large, but feel free to thumb through the list. It’s meant as an instructional aid to show that needle in a haystack is sufficient when the haystack is large enough. This particular haystack is larger than the number of protons in the known universe.
Kinda like saying… my friend painted a proton blue and shot it into space. I’m going to go find it now.

to OPs credit, it is not “if” but “when”, and currently the time component for a brute-force attack is essentially infinity.
but this ignores another tenet of cryptography (and i paraphrase) that no algorithm is secure until it is cracked. put another way, you cannot know the true security offered by an algorithm until you know its weakness (and thus, its limit/utility.)
all algorithms eventually show a weakness, often coinciding with an increase in computational ability, for example rc4 was considered reasonably secure … until it wasn’t, now anyone using rc4 to protect anything for longer than a minute would be laughed out of the building. it is only a matter of time before elliptic curve or PBKDF ‘mashing’ algorithms are provably weak either to some future state of technology or an academic proof that allows for the generation of a subset of valid keys (given a set of known public components like addresses.)
anyone that denies this works outside of cryptography.
i agree with everything everyone else has said, but if we’re going to be honest, eventually the algorithm/standard behind the use of “seeds” will need replacing, along with every private key associated with them. it might be 10, 20, or 50 years from now but it WILL happen eventually.

The words in your seed phrase are from a standardized list of 2048 words. Each word represents a number. Those numbers are used in the math that generates your wallet.
If you use a passphrase, each character in your passphrase represents a number, and those numbers are used as your own custom entropy as part of the math that generates your wallet.
Thus… your seed words (and passphrase if you use one) are all you or anyone else needs to rebuild your entire wallet on another device. Any device, not just a Trezor.
**Let’s talk about the odds of somebody guessing!**
To play the Powerball lottery, you pick 5 numbers from 1-69, plus a Powerball number from 1-26.
You win a million dollars if you can guess the first 5 numbers.
The odds of winning a million bucks are 1 in 11,688,053.
The odds of guessing all 6 numbers and winning the jackpot is 1 in 292,201,338.
1 in over 292 million!
Here are the odds of somebody guessing a 12 word Bitcoin seed phrase:
1 in 340,282,366,920,938,463,463,374,607,431,768,211,456.
For a 24 word seed phrase, the odds are:
1 in 1,976,184,989,650,196,401,895,611,477,481,606,960,695,807,738,293,598,959,606,742,767,068,384,079,188,241.
There aren’t that many grains of sand on Earth.
There aren’t that many ATOMS on Earth.
According to the US Department of Energy’s Jefferson Lab, the number of atoms on Earth is roughly:
133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.

> Can’t someone just take a new hardware wallet and just keep inputting any random 12 or 24 words and eventually will land in someone’s wallet??
Yes, and you might find one after trying for trillions upon trillions of years. That’s probably an underestimate.
There are 2048 words to pick from, and you need a specifically ordered combination of 12 of them. I believe the math on that is something like 2048^12. Pop that into Google and divide it by the number of times you can enter the seed phrase per minute, or get a computer to guess it per second.
