You can't really tell either way. But at least when doing it yourself you can verify the process. With software RNG There's no way to know. You just trust the software did a great job.

At the end of the day, no matter how many processes core supposedly goes through to generate a key, you still can't verify it's been done correctly.

So you're 100% sure that instead of reading again the same bits, it assumes the rest are zeroes? You know that or you think that?

Oooh ok I just read the whole thing. Yeah that make sense to me. 40 random bits then a lot of zeroes.
So it's not exactly like having a modulo with 40 bits and reading it in loop until you have 128 bits.

2026-09-11 20:56:33 UTC

"but they contain only 40 bit of entropy"

Idk

2026-09-11 20:12:57 UTC

- reply

Is me putting 40 bits in my modulo then reading those and trying derive a seed from them equivalent of a 40 bits coldcard seed?
Or are those different things?
What I like about the modulo is I can very easily see and understand 40 bits and what it would mean to use those same 40 bits to read until I reach a full 128bit key. But when you guys talk through the lense of a random number generator it seems like 40 bits means something different.

Reused **in the same pattern**
This si what creates the weak security.
(From my understanding)

2026-09-11 20:00:00 UTC

- reply

I don't understand what this means.
For me, 40 bits means 40 one and zeroes.
To generate a full valid seed you still need at least 128 bits. All those coldcard seeds contained at least 128 bits. Without those 128 one and zeroes there cannot be a seed.
So when I hear a 40 bit seed what I have to assume happen is that those forty bits have been reused to reach 128 bits.

2026-09-11 19:56:40 UTC

- reply

But I don't think that's the case.
Take the exemple in my original note. It is possible albeit very unlikely that even tho you use a coin flip to find your key that you will obtain 00000...0000.
In that very specific case, I believe it would be accurate to say that this seed is "high entropy" as it has been discovered through unpredictable randomness but I also believe this sees would be more likely to be guessed by an algo and therefore this seed is less safe.

2026-09-11 19:51:11 UTC

- reply

Does 40 bits means that the exact same serie of forty 1 and 0 was refused multiple times?
This is how I understand it.

2026-09-11 19:50:14 UTC

- reply

Yeah the graphic isn't right. Instead of saying entropy it should say hard/easy to guess.
Because the ones at the very bottom could've been found with a high entropy method and still be easy to find.

2026-09-11 19:46:03 UTC

This leads me to believe/understand that high entropy is a tool more than a result.
By using a "high entropy" method of selecting bits like a coin flip, you make it more likely to reach one of those very high and hard to guess keys. But high entropy does not in itself mean that you will obtain the safest seed.

I think we 1000% agree.
But just to be clear, you agree that Bitcoin keys could be visualized in this way where some keys are, wether they've been generated with high entropy or not, unsafe to use? Which also means some keys are more and more safe than others.

I think the conclusion that I'm reaching is that high entropy does not necessarily mean hard to guess even tho it is strongly correlated.

2026-09-11 19:12:05 UTC

- reply

So the image I posted is likely correct. You can visualize all the possible keys in an inverted cone and some very "low entropy" keys are at the bottom.
Some Bitcoin keys are "born" low entropy, or, in other words, easier to guess even tho, mathematically speaking, they all are just as likely wether you use a perfectly random method to discover them or not.
I'm not sure which conclusion can be derived from that I just started thinking about it but I find it interesting.

2026-09-11 18:39:59 UTC

- reply

Yeah, I don't disagree with you here. That key, even tho it appears to contain some patterns, can completely random.
But I'm trying to lead you down a tough experiment with an even more extreme case. Imagine if, instead of the key you obtained you would have obtained a key that can be read as 00000000....
In this case, even tho you went through the exact same process and you have divine knowledge to know that it has been generated randomly and therefore has been generated with "sufficient entropy", would you feel safe using it?

2026-09-11 18:22:37 UTC

- reply

IF the algo guessing has no pattern.
My guess is, and I could be wrong, that an algo trained to find your key would be looking for certain patterns first. Like for exemple starting will all zeroes then go upward from that with the following seed being all zeroes except 1 at the end and so on...
If that's not the case, then any see is truly just as random and difficult to guess as the other. In that case, how is me consciously selecting 12 words less secure than I seed found through dice rolls?

2026-09-11 18:12:04 UTC

- reply

If you had divine knowledge and you knew for a fact your key was generated in a perfectly random way and that key resulted in only zeroes, would you consider that key to be "high entropy"?
Purely mathematically speaking I think it would objectively be considered "high entropy" since this concept is about the process not the result. But I think we (bitcoiners) use the term differently. What we mean to say is guessability. But the two concepts are not completely unrelated.
I think what we're looking for is a hardly guessable seed and entropy is a way to find this.

A thought experiment about entropy
Imagine a perfect random machine generates 128 bits. Every bit has exactly a 50% chance of being 0 or 1.
It produces:
00000000000000000000000000000000…
The probability of producing this exact sequence was 1 in 2¹²⁸.
Now imagine instead it produces:
10110100111001010010110101110010…
The probability of producing this exact sequence was also 1 in 2¹²⁸.
Mathematically, neither outcome was more likely than the other.
And yet, if these values were being used as secrets, which one would an attacker guess first?
Obviously, all zeros.
The machine did nothing wrong. Its process was perfectly random. It simply landed, by extraordinary chance, on a value that is highly predictable to an attacker.
This leads to an important distinction:
Equal probability of generation does not imply equal difficulty of guessing.
Among all 2¹²⁸ possible values are a tiny number of extraordinarily simple ones: all zeros, all ones, alternating bits, repeated patterns, counting sequences, and other values an attacker would naturally test first.
A perfect random process can produce any of them. It is just extraordinarily unlikely to do so.
These are the values people often intuitively describe as “low-entropy keys,” although technically entropy describes the process or probability distribution that generated the value, not the individual value itself.
So where would you place 000…000 in a map of the 2¹²⁸ possible values: among the enormous mass of difficult-to-guess values, or at the very bottom among the tiny set an attacker would try first?

But I understand the intuition you had. Its only because I've been holding and looking at my modulo with 128 distinct bits that I've reached a different conclusion.
I really think the modulo make you think differently in a good way about this stuff.

2026-09-11 03:41:56 UTC

Some people believe they can generate a 24 word seed with more than 128 bits by reusing the same 128 bits in a new pattern. I think they're wrong.
A 24 word seed generated with 128 distinct bits cannot have more than 128 bits of entropy.

- reply

Enki, I don't know which tree you have and maybe for you it's different but imo I wouldn't touch it yet. Not until the trunk is the size you want.
My plan is to wait let me trees grow freely for a few years up until the trunk is the size I'm looking for. Once I have it I'll cut it all from the trunk leaving no branches.
Only once branches start coming back will I start thinking about trimming. I don't really have a plan for trimming just yet because I won't concern myself with this for a few years.
Cutting the trunk lie that allows you to create a rapper in the trunk which will give your tree a very old look very early (relatively speaking) in it's growth.

But both solutions aren't in the same category imo. Modulo in his a category of its own.
It's not just a simple seed plate. It's a tool to generate AND preserve randomness. Not only that but I recently realized in each Modulo you can easily read 16 different seeds just by reading it differently. And after that if you really want to be sure nothing stop you from creating a backup on a seed plate.
I like the fact that Modulo keep proof of the entropy. I'm not sure I'm going to use the world well but you'll probably understand what I mean: proof of entropy feels like a first principle approach to cryptographic key holding.
