A bit off-topic: I remember having checked how "normal" Electrum handles normalization with the optional mnemonic passphrase. I can't remember if I found something strange or unexpected, but I remember that there was something that surprised me. But I forgot or didn't document for me what it was.

pooya87 and I discussed this on a previous thread here: https://bitcointalksearch.org/topic/m.61745337

The summary is that Electrum makes everything lowercase, removes all accents/diacritics, and removes all duplicate white spaces.

As it usually is the case, the devil lays in the details. I have difficulties reading and fully understanding Electrum's source code. And I admit, that I haven't tested test vectors as thorough as needed with the modified script. Subtle differences with normalization can indeed throw things off. Thanks for pointing this out.

It is rather easy to modify the iancoleman.html script for ...

It sounds easy on paper but to truly implement the same algorithm takes a lot more than changing two lines of code. Specifically speaking the normalization method that Electrum uses for both mnemonic and the extra word (AKA passphrase) is very specific and slightly complicated to duplicate. As we can clearly see in this copy you shared the code for normalization is not implemented at all. If we test the html result it also doesn't support other languages and it also doesn't normalize the passphrase correctly. Test vectors can be found here

The modified iancoleman-Electrum script can't generate mnemonic words from entropy AFAIR, but my memory might be clouded, it's been some time ago I used and played with it.

Correct. The process for generating Electrum seed phrases is quite different to that for BIP39 seed phrases, and requires repeatedly incrementing the entropy to reach one which gives the necessary version number on hashing. It would require significant chunks of new code to be able to generate Electrum seed phrases. As you say though, the changes required to input Electrum seed phrases are very minimal.

I checked the small changes from the forked iancoleman version and it looked safe to me. But as usual: DYOR and DYOV (V=verification)

- There is what Electrum uses but there is no documentation of the algorithm, you'd have to read the code in python and understand what it does which is not suitable for someone who wants to implement it for another wallet specially if the program language is different. There is also certain features of the algorithm (like being loose about the word list used) which is not something all developers agree is a good idea.

It is rather easy to modify the iancoleman.html script for verification of Electrum mnemonic recovery words and key and address generation, there's really no heavy changes in the algorithmic logic to accomplish this. The modified iancoleman-Electrum script can't generate mnemonic words from entropy AFAIR, but my memory might be clouded, it's been some time ago I used and played with it.

I think this was the source of the modified script, it's forked from an older version of iancoleman script: https://github.com/FarCanary/ElectrumSeedTester

Why is it popular?

Just wanna add to all reputable responses. BIP 39 mnemonic phrase relies upon build-in checksum data which reduces the risk of accidental typos. I don't say that it is the main root of its wide adoption but probably one of them.

Nah, the only reason for BIP39 adoption is lack of alternative or better say a "better" alternative. There are two other options and they are, lets say, "challenging to adopt".

Yeah, "better alternative" available at the right moment would be likely a winner, but the truth is there were no "better alternative" at the time when BIP39 has started to spread. Now I'm in a big doubt that any alternative, "better or worse, "appeared right now would surpass BIP39 as it would require full reconstruction of the wallets' "industry".

- There is also Aezeed which is pretty new and the algorithm makes implementing it is very complicated because it depends on an cryptography algorithm that is not common at all called AEZ. That means the developer is not being able to find a library/package for it to use in their project like they'd find for something like SHA256. There's is pretty much only the official C implementation on their website which they'd have to write a wrapper around for any other language which is a pain in the butt. It's also an overkill since a mnemonic's strength is in the entropy it uses not the key derivation algorithm under the hood.

I have no doubts that people can memorize 12 or 24 mnemonic words or 10000 digits of Pi. Once you learned them, you have to continue to repeat them and don't miss to verify that your memory is still accurate. Your head might be the safest storage for your secrets but it's also the least reliable one. To verify reliably, you need a safe copy and because of that I consider sole memorization in your head as pointless and dangerous. It has proven more than once to be a recipe for desaster.

If you stop repeating and verifying, you're likely going to introduce errors or forget parts or almost all of it. A trauma or severe illness can erase (big) parts of your memory. I wouldn't want to rely on my biological memory for longer time because I know it will fail me sooner or later.

It's not my cup of tea.

No software, no hardware currently in existance on this planet can help you to find your missing nine words in your lifetime. Additionally the required energy to find your words is likely much more expensive than what your wallet probably holds.

And people choose 24 words seed phrase because they think it's way more secure than 12 words but on top of that, they prefer to use their own wordlist instead of BIP39 mnemonic phrases because it's public Cheesy

Quote from: Cricktor on July 03, 2023, 07:54:54 AM

Think hard: how did you memorize your twelve words? Some people create a story with the words or similar techniques. It's hard to believe you didn't have a physical copy for the training and memorization phase. What happened with that copy?

Didn't you regularly repeat and check your memory? To verify your memory, you need a physical copy. And this makes memorizing the words pointless, except for a short time if you have to cross a border under distress or similar situations where keeping a physical copy could be harmful.

It's not hard to memorize 12 words if you regularly repeat those 12 words over and over again, every day, multiple times a day for weeks or months. A lot of people here are skeptical about this idea for some valid reasons though, but writing down on paper or telling its location to someone else is risky as well.
I would say, memorizing of 12 words is the most secure and untouchable way to store seeds in this world.

If you don't understand the English language good enough, use DeepL or Google translator. Nobody can find missing nine words out of a twelve word mnemonic recovery. If you had them only in your memory, then this was a terrible mistake. It's a recipe for desaster to not have a physical backup of your mnemonic recovery words. And your issue is proof for that.

There are many wallets that can be used for recovering your wallets. (Note that most wallets use standard derivation paths and there is no need to save or write down the derivation path at all)

There is no possible way to brute force 9 words. Did you write your seed phrase down on paper like you are supposed to? If you did, then go an retrieve you back up. If you only committed it to memory and have forgotten 9 words, then you coins are lost I'm afraid.

In addition to BIP39 and Electrum seed phrases being discussed here, note there are also other phrases in use, such as Aezeed for LND, old style blockchain.com password phrases, or SLIP39 phrases.

The main purpose of creating mnemonic out of an arbitrary data is to be able to write down that data and later on to enter that data in the application. Compare entering a base58 private key and entering a 12 word seed with your keyboard.
It is not easy nor suggested to memorize the mnemonic.

Right. Read the post made by o_e_l_e_o in another thread before.
If you miss 6 words, it would take around 44 million years to brute-force the seed phrase. Even 4-5 missing words can't be brute-forced, let alone 9 missing words.

You are missing 9 words, every word encodes 11 bits of entropy, that is equivalent to 99 bits of missing entropy. I've done some recovery stuff with btcrecover but never with that much missing (I wouldn't have started such a quest because it would've been a waste of time and energy).
My educated guess is: this is too much missing out. You don't have the time and energy to search through 99 missing bits.

It's good if you're sure about the last word, because it contains a 4 bit partial hash checksum, but still you need to find more of your words. Correct sequence position is not important, that you can brute force with less work. But having 9 completely missing words is too bad and I'd say not breakable.

Why do you have only such a small fragment? Could there be somewhere another copy?

Open a separate thread for your recovery issue. But if you can't find more words, it's very likely pretty much hopeless.

Why is it hopeless? 2^99 are 633,825,300,114,114,700,748,351,602,688 possible choices. Way too many...

The BIP39 mnemonic recovery words encode a random number of 128 bits (with 12 words) or 256 bits (with 24 words) in a more human friendly way, to write it down without errors. It's this random number that is the starting point for all the further deterministic derivation to the private keys of your wallet.

You would have a hard time to write 128 or 256 zeroes and ones without error. Likely 32 or 64 hexadecimal digits aren't human friendly to backup, too.

And those mnemonic recovery words even contain a partial hash checksum which very very likely allows detection of an error, be it misplaced, replaced or wrong words. It doesn't give you error correction, only detection.

Is it now correct to say that all the wallet sees phases are backward compatible?

No, the correct word would be "the standard" since it's the most implemented mnemonic seed for HD wallets.

"Backward compatible" is: If the new version of a software still supports something from its old version.
For example: Electrum's old seed is different from the new ones but it can still be imported to the latest version.
(take note that none of those seed phrases are BIP39)

Take note that it's not that BIP39 seed phrase is the new version of electrum seed phrase or vice versa. They are completely different types of seed phrases.

Almost all non-custodial wallets (with a few exceptions) support BIP39 seed phrase. If you have a BIP39 seed phrase and you know the derivation path, there's nothing to worry about. There are many wallets that can be used for recovering your wallets. (Note that most wallets use standard derivation paths and there is no need to save or write down the derivation path at all)

If you have an electrum's seed phrase, you can recover your wallet using electrum itself and bluewallet. Again, there's nothing to worry about.

I doubt you have any other type of seed phrase.

Incase we have seed phrases that are not compatible with different wallets, how do I see a complete seed phrase and identity the wallet that generated it?

To add to the above, pretty much all wallets use BIP39 to create wallets, with the exception of Electrum which has its own system[1].

You can still import BIP39 wallets to Electrum though, but an Electrum seed will only work with Bluewallet.

I read a while ago that Sparrow wallet has internal support for Electrum-generated seeds, but they haven't implemented it yet. Maybe it's a topic they will reconsider in the future. Here is what they say about it:

Quote from: dkbit98 on June 30, 2023, 03:43:41 PM

BIP39 was created by Trezor developers and it become a standard for most hardware and software wallets.
Electrum wallet later made some improvements and created their own seed phrase system, but they also support importing BIP39 phrase.

When Electrum came out, there was no BIP39 standard yet, so there was no way of them supporting it in those days, just like pooya87 pointed out.

Incase we have seed phrases that are not compatible with different wallets, how do I see a complete seed phrase and identity the wallet that generated it?

You should try to remember what wallet you used to create the said mnemonic and that would help with identifying the type or algorithm used in its generation in addition to things such as derivation paths used when creating the child keys/addresses.
Otherwise if you want to know the type of the seed phrase created by someone else is, it is hard since in some cases one mnemonic can be valid in multiple algorithms (eg. an Electrum seed being a valid BIP39 and vice versa). Not to mention that some wallets use crazy derivation paths that can not be guessed without knowing the wallet first.

Electrum had a seed phrase algorithm from the day it was created which is in 2011, Trezor came about 2 years later in 2013.

My question is BIP39 mnemonic phrase is very popular. Is it a unanimous phrase standard?

It became popular because it was the first to do something like this, that makes life and backup much easier.

I don't know what you mean.
All wallets are compatible with BIP39, only difference can be with derivation paths that can be different with different wallets.

Last I was aware, Armory wallet also generates a seed phrase that's not Bip39 compatible. I haven't played with Armory very much at all, and it's been years since I have, so this may have changed in recent years.

Yes that's true, the release version which isn't updated since 2021 is using its own backup scheme.
But the development version has recently updated with BIP39 support just 4 months ago, the developer doesn't have an ETA on the release date though.

All wallets use BIP39 with the exception of Electrum so you're not going to have anya compatibility issues.

We should not assume all unless it is tested and known to support BIP39 seed phrase. People using wallets that are not reputed may find it too late before they will realize that their wallet is not BIP39 wallet.

Like this example that we discussed in the past: To be careful of the noncustododial wallet we are using these days

To add to the above, pretty much all wallets use BIP39 to create wallets, with the exception of Electrum which has its own system[1].

You can still import BIP39 wallets to Electrum though, but an Electrum seed will only work with Bluewallet.

You can not know a wallet that generates a BIP39 seed phrase. But you can know if a wallet is BIP39 seep phrase or not.

To know if a seed phrase is a BIP39 seed phrase, import it on a wallet that support BIP39 seed phrase and check if the addresses are the same. Do it with a seed phrase generated for an experimental purpose, not your coin seed phrase.

This could be a simple question, but I will not pretend that I know while deep down me, I do not know.
