A word is reusable. Considering the last word checksum, the exact combinations count is: 12 words combinations = (2048^11)*128 = 2^128. 24 words combinations = (2048^23)*8 = 2^256. In a 12-word seed, the last word has 128 correct options. In a 24-word seed, the last word has 256 correct options. The BIP39 seed is a system to reproduce a 128 or 256-bit long key by a 12 or 24-word seed, easier to write down for a human without mistake.

Great video John but I wanted to add something else. Can you have two matching words? Does anyone know if this has happened? Not that it matters much but technically, there would be less combinations because you woud have to use the formula, 2048 X 2047 X 2046 X 2045 ............. . This is still a number larger than the number of particles in the universe which is 10 to the 80th power. I should also add that even if you do guess all the correct words, you then have to put them in the correct order. That would be multiplying it by 24!. (That's 24 factorial, 24 X 23 X 22 X 21 ......) You got 2.96 times 10 to the 31st power for the 24 words, but you didn't multiply by 24 factorial.

there are 2028^24 combinations or 10^77 (decimal,)which is slightly bigger that SHA256 (2^256), that is 2^264 (binary) to be exact, because a mnemonic phrase also has a checksum. Meaning that the possibility of someone guessing 24 out of 2048 words in the correct order is 1:10 followed by 77 zeros. For illustration 10^77 is more than there are a number of atoms in the observable universe. You are safe...as long as you do not choose the words yourself, as you will not do it randomly enough. Never ever choose your own mnemonic phrase always trust a specialized third party like Ledger or Trezor to do if for you.

Nice video, I like the explaination with the papers. But you would need to discard the invalid mnemonics, not all combinations are valid as it needs to test the checksum. You calculated an upper bound of the combinations. It would be nice to see an updated video with the exact real number of combinations (which would still be extremely large).

I would like to understand the mathematics behind how a single 24 word seed gives rise to everything else. For example, how do we derive the public and private keypair for a wallet, and how do we derive an address? Can a single address be controlled by different private keys owned by different people? Specifically, different bits of coin associated with that address are encrypted by two different owners. And we're not limited to a single address either... how are we able to derive the entire sequence of addresses and how many are in the sequence? Do they all have the same private key or does each get a unique private key? How is the calculation different across the different coin and token types?
@soulreaper9453
@soulreaper9453 2 жыл бұрын
It all starts with random numbers generated by a user or wallet software. From the randomness, you first get a private key which will generate a public key (It's a one way process because A public key cannot generate a private key). The mnemonic phrase is only a human understandable representation of the private key the same way a Web address is a human understandable representation of a domain IP address

You've explained the probability of guessing a single, specific 24-word BIP39 seed phrase. However, wouldn't the chances be higher if we're trying to find any one seed phrase within a set of a million distinct seed phrases? Presumably, we could calculate this by dividing the previously given probability by the number of unique seed phrases in this set. Moreover, if there were 1 billion individuals each attempting to guess a correct seed phrase 100 times, wouldn't we further divide the probability by the total number of attempts, which in this case is 100 billion? Is my understanding correct?
@SirWifHat
@SirWifHat Жыл бұрын
You are correct. If you are looking for any one of a million specific seed phrases, and not just one particular seed phrase, then you would indeed divide the probability I gave by one million. And yes, if a billion people each tried a hundred different seed phrases, you'd have 100 billion total attempts, so you would divide the probability by 100 billion. However, keep in mind that the probabilities we're dealing with here are still extraordinarily small. For example, if we consider the case where we're looking for any one of a million specific seed phrases out of all possible ones, the odds become roughly 1 in 10^73, assuming 2^264 total possible seed phrases. Even if a billion people (10^9) each tried a hundred (10^2) seed phrases, that's 10^11 total attempts. This brings the odds to roughly 1 in 10^62. These are still astronomically small probabilities. Even with a billion people making a hundred attempts each, the chances of correctly guessing a specific seed phrase (or one of a specific set of seed phrases) are infinitesimally small. To put it in perspective, you're still more likely to win the Powerball lottery multiple times in a row than to correctly guess a specific seed phrase or one of a set of specific seed phrases in this scenario.

But, as human beings are really bad to choose real random words, if you want, you can write the 2048 words in pieces of paper and pick the first 23. For the last one, you'll need a checksum calculator and find the final word. But don't do this online.

Is choosing two words 2048^2 permutations, or 2048P2 ? Ive never been sure if replacement was allowed. And yes, I know the number of permutations is astronomical... but consider the fact that most wallet owners have multiple different wallets, many old and disposed of or forgotten about. Consider that there are thousands upon thousands of crypto owners across the globe and the number is growing. Consider that there are supercomputers that could run through these permutations at lightning speed for the sole purpose of stealing crypto. Much worse and much more nefarious scenario than two people just "accidentally" generating the same wallet. Talking about the number of permutations alone isnt a fair treatment of the probabilities involved, nor is it a fair discussion on the brute force tactics that might be employed. I trust it is by far easier to steal wallets by regenerating them from a word list, than it is to target a single wallet on the blockchain and hack its encryption.

Yes, repeats are allowed. I'm afraid you don't quite understand the numbers involved here. It doesn't matter in the slightest about the number of wallets "across the globe" and its growing number, or disposed of wallets forgotten about. They are insignificant, and forever will be. To put things in perspective, you could have a trillion trillion people (10^24, more humans than there ever will be) generating wallet seeds and it still wouldn't matter. Brute forcing a seed at "lightning speed"? Even the NSA assuming 1 trillion guesses per second would take millions of years to get through just half the possibilities. Not worth it.

@@matthewmoon2463 Are we sure though that two seed phrases wont ever produce the keys to the same wallet, ever? The space of possible addresses has got to be infinitely larger than the space of possible seed phrases that produce them.

@@leesweets4110 Hi, Lee. The space of possible seed phrases is approx 10^67. So, we're not dealing with infinite spaces. They are huge, but not infinite. Infinity is a concept, but not a number that makes much sense. Any finite number (like 10^67, or even 10^67000), no matter how large, is infinitely smaller than infinity (an interesting concept to think about). John talks about a mental model of atoms in the visible universe being the size of the seed phrase space (a close approximation). If you were to somehow pick a random atom from the universe, what's the probability that I would zone into the exact one you did, assuming my pick was random? Is it possible? Yes, the model is open to the possibility. But the probability is so close to zero, that it's practically zero. Even with trillions of people all making keys. For example, a trillion people who've all made keys is 10^12 people out of 10^67 possible wallets. But that's equal to a single person matching a wallet from 10^55 possible wallets. We haven't moved the needle here. Not even a dent. In order to get slightly worried about wallets matching, we'd need to start getting close to a trillion trillion trillion trillion (10^48) people generating wallets. THEN the numbers get worrisome. I can guarantee you there will never be that many wallets generated, ever.

A word is reusable. Considering the last word checksum, the exact combinations count is: 12 words combinations = (2048^11)*128 = 2^128. 24 words combinations = (2048^23)*8 = 2^256. In a 12-word seed, the last word has 128 correct options. In a 24-word seed, the last word has 256 correct options. The BIP39 seed is a system to reproduce a 128 or 256-bit long key by a 12 or 24-word seed, easier to write down for a human without mistake.

This is amazing! Imagine that all living people (8 billion) somehow have been creating 1 thousand bitcoin wallets per second since the beginning of the universe (13,8 billion years ago). We would "only" have 3.5*10^30 wallets. And the chance to find any would be 1 in 10^49.

Anyone who thinks or doubts that two persons might randomly get the same 24 words combination, may add the 25th word (AKA passphrase), so that you and only you know what that 25th word is. Even if another person gets the same 24 words, he / she wont be able to access your funds (assuming you held all your crypto on the accounts that was generated using the 25 words)

To be absolutely sure go to a coin you sure you own and see if there is any log history with it. There should be many ways you can search your public key online to see if there is a transaction history. If I try to tell you how in a YT comment the YT AI will just auto delete my comment.
