    The funny part is that the child understood/explained it better than the Teenager 😬

    Well, the topic was brilliantly explained. However, I do not understand, why the proof for Child level was better than for Teen level.
    Because when you are hacker, you can basically see, how is the 1st person dialing the numbers (on the safe lock) 🤔

    I enjoy these – and the host (Amit) is good at this. I often find the first level (child) is my favorite. I enjoy hearing how each person communicates what they just learned.

    Aside: I get the feeling that the host is the type of person who could come tell you that your house just burned down and you’d be okay with it. He’s got such a great demeanor.

    The moment he brought up the fact that this could be used to prove that an election was done correctly, sounds like he’s got an agenda and he’s a Republican, trying to state that just because we say that Biden won, doesn’t actually mean he did win, .. it just means that they have convinced everyone without proof

    There’s a set of rules to information that are always true and that must be applied for the operation to determine truthness and verification thus knowledge not just information. In any randomness, these traits are always true thus verification. I guess? Haha.

    This is stupid, each example is obviously stupid. WHY? There’s so much wrong with this!

    Hey, look, I can explain this to a child whose IQ is OBVIOUSLY above 160! (Jordan Peterson says that that’s the highest score, but of course some people would score ever higher if the test asked harder and harder questions.)

    And then the 2nd “proof” didn’t prove that he needed to know the combination. she took it on trust that it was a true safe.

    The college student is a computer science student. He OBVIOUSLY already thinks exactly like the presenter.

    Shouldn’t it be that the proof should convince the average college student, and not one majoring in the subject? And the average 10 year old, and a skeptical 13 year old? At thirteen, I would’ve said, Hey, let me examine that safe and let me hold it while you turn the combination with just your fingertips, but not so that I can see the combination.

    And “the child” is obviously very much like the “college student.” Doesn’t it seem to you that, actually, she’s more gifted in this area than the “college student”?

    And the proof for the 13 year old is actually much less sophisticated than the one for the 10 year old.

    I’m not going to watch more.

    This theory needs a better name. It’s a misnomer. Clearly by the examples, the professor has demonstrated his knowledge about what he claimed to know. It just that he doesn’t reveal some information to reach to what he knows.

    My favorite part of this was when they (the postgrad and the expert) moved into the whole philosophy of it: what is ‘knowledge’ and what is ‘data,’ when you have the ability to predict additional information during a transaction?

    That gives me mad chills thinking about it

  63. Hedde van Heerde

    January 20, 2022 at 6:56 pm

    Something I’m curious about regarding this topic is energy requirements. If I’m understanding this correctly (and I definitely don’t fully understand the concept yet), the verifier gets more security because the prover can get something right every time – which if done enough times, gives the verifier enough reason to believe the prover must’ve known the secret to get it right every time.

    My question is, wouldn’t this increase the energy consumption for these zero knowledge proofs compared to a proof where you do give up a bit more of the secret? My main concern with security like the Blockchain is its energy consumption and I’m wondering how this ties into that.

    • MBW W

      January 21, 2022 at 12:41 am

      I don’t think so. In both the 3 color map and puffin in penguin examples the “revelation” is simply the result of applying a random number against an answer known only to the prover, but not the verifier (x/y shift for the puffin, randomly assigning a color to an ordered set of colors for the map). Random numbers are easy to generate.

    • Hedde van Heerde

      January 21, 2022 at 1:21 am

      @MBW W I don’t think one such calculation is particularly hard to do, my point is that it only becomes a proof once it’s done enough times to establish that it can’t be chance that they got it right each time. Even if as little as ten attempts were needed, that’s still ten times as many data as doing it once (with a different type of proof). However, how the blockchain works is also extremely energy consuming… I’m basically wondering whether this would be a step forward or backwards when it comes to security’s energy demands.

  65. joseph keane

    January 20, 2022 at 7:37 pm

    his 1st example is total crap “zero knowledge” but he knows where the puffin is he even admits he knows! then he places it behind the canvas in the presice spot so she can see it!!!??call me crazy but im quite sure he had knowledge of the puffins location! so stupid and this is science what a joke

    • Eli Jaffe

      January 20, 2022 at 7:40 pm

      “zero knowledge” refers to the fact that the verifier (Chelsea) gains zero knowledge during the verification. that is, she doesn’t learn the location of the puffin, but she is convinced that it is there. the prover must always know why the statement is true, otherwise they would have no way to prove it at all. hope this helps 🙂

    • joseph keane

      January 20, 2022 at 9:55 pm

      @Eli Jaffe yes i get that im not stupid however his knowledge is directly passed on to her by setting the pic in place for me its basically i think your lying or your telling the truth you either believe or you dont also the knowledge is gained upon the verification lame examples are used in this clip imo

    I think whoever solves the P vs NP problem will open pandoras box on this. If P = NP then you can just convert your NP problem to a P problem with a unique algorithm and solve it in P time (how cool would that be), else there exist no NP problem that can be converted using any algorithm. P.S. I’m not a trained mathematician or computer scientist, so please enlighten me if I’m wrong, I’d love to be corrected.

    Sorry, BUT, It’s more like “Trust in the prover”. All this demonstrations imply that you trust the “prover” :
    – Level 1 : how to be sure the image behind the hole is the same image ? You have to trust on parole the prover.
    – Level 2 : how to be sure there is no trick to open the safe ? The prover only show you that he can open the safe. He probably know the combination but maybe not. This can be a toy safe or magic trick safe.
    – Level 3 : humm this one is hard. you need to trust the system in place = the map. The map must not have the same colors next to each other. So what ? Why does this mean that the information behind is correct? An intermediary can hide between the information and the map.

  105. Hexum944

    January 22, 2022 at 8:56 pm

    The first two demonstrations should be flipped. The first girl should have the lock box demonstration, and the next girl should have the picture demonstration. This order is more in line with the complexity of the demonstration for the appropriate age.

    January 22, 2022 at 9:00 pm

    I feel like they skipped over the step of “someone who understands np-completeness but not zero-knowledge proofs.” The grad student was doing his thesis on the topic so didn’t really need any teaching.

    Even the first version doesn’t make any sense. You have to take someone’s word that there’s a puffin in the first place and that it’s the same picture behind the screen. That’s not proof by even a child’s definition of proof.

  111. Christopher Burk

    zero knowledge, zero proof. The location of the bird is not actually proven if you think about. How do you ASSUME its the same picture?

    I’m not sure I’m convinced. Can zero knowledge proofs really get parties who mutually mistrust each other actually working on common projects? Aren’t there more than just issues of what we know and don’t know about shared information involved in problems of trust? It strikes me as a very narrow solution to a theoretically very narrow problem… it also seems to be a strangely band-aid like solution to a deeper problem which is not being addressed. But, I am not a mathematician and am probably not grasping the novelty or beauty of this idea…

    The ability to prove something without sharing secrets is great but may be already present around for a while. On the whole this approach must be perhaps hiding something important to us as it is stated at 4:50 – we do not trust each other – the impression of the verifier – also the impression of the approver.

    January 24, 2022 at 11:41 pm

    Never heard of this until now, haven’t finished the video yet. But to me it seems the easiest way to implement a zero-knowledge proof would be to encrypt a message, where the encryptor doesn’t know the decryption algorithm but the decryptor somehow knows how to decrypt the message. I could be wrong. But also the encryption can provide information of how it is decrypted — wtf.
    At 7:03 atm Wait, couldn’t someone use assembly and look for patterns of instructions that are similar as an attempt at decrypting the message basically brute force, or is there some ancient math algorithm that does something similar?
    I’m at level 1, but the last person so far it is great listening to them speak.

    I really like this. However, I’m deeply dismayed that that the simpler proofs went to females. Male-presenting folks were chosen as the older recipients of the more complex explanations. Can older females not get it? The choice in learners in this video support an implicit bias that females can’t learn higher levels of math and science. Not good.

    Amazing video. When I took theory of computation in my professional masters program at University of Washington, the example my prof gave was of an alien claiming to have solved chess. As the verifier, you would convince yourself by playing it chess, perhaps using the most powerful chess engine available. If the aliens keeps winning you gain confidence in its statement. But at no point would you learn how the alien actually solved chess

She would say if are unable to explain what you our learning in a way that even a six yr old could understand then YOU never really understood it to begin with. My god what a good strategy that is!!!

    This is actually used in many ways, for example in Windows systems you don’t really store the password on hard drive, just the encrypted version of it and every time, when you try to login, the encrypted version is compared to the on you’ve just entered after being encrypted. It is called the OWF or One-Way Function store. That way password manager will never actually get your password, only the encrypted data and thus verifier can prove you know the password by comparing the two strings.

    I couldn’t agree more with his hope that cryptography can help bring together mutually mistrustful groups, and groups with such different assumptions they almost seem to inhabit different universes, in a way everyone can trust in a factual claim such as the outcome of an election. This is quite at odds with those who wish to create trust by fiat or consensus judgement. I hope they are successful.

    child level was good.  
    teen level was excellent.  solid, I’d even say.

    the next up did not even feel like they “proved” they were using the 3-color-map problem; those other envelopes could have had all the crayola colors for all we know, and the student didn’t call him out either on that, nor on the follow-up of how this could reflect in Believing he has… 0.3 bitcoin? 0.2? greater than 0.2 but no more than…? that middle level just was not clearly useful to the space.

    the more academic levels were perspective but not so much demonstration either. I had been hoping for a deeply tech dance that revealed a similarity to the lockbox and combo.

    Bro this guy is a great teacher. The way that he asks the earlier ones ‘based on what we discussed what is zero knowledge proof to you’ is genius because now the person needs to explain the concept based on what they have learned and in that moment they are not passively learning (by listening to a lecture) but also actively learning by applying what they have heard.

    Yes, as a pastor this is a familiar concept; faith is not blind, it is based on convincing proof of something we cannot see.

    Hebrews 11:1 Now faith is confidence in what we hope for and assurance about what we do not see.

    If a zero knowledge proof can be used for np-complete set, how does one know that all the problems in the np-complete set belong in the set such that the zero knowledge proof applies to all of them? I probably need to study np-complete and perhaps can find an answer, but I’m super busy.

    ok, so my question is, how does the prover know that something is true to begin with? They may be able to convince the verifier that its true but I’m curious as to how they know its true themselves?..or do they not actually know if something is 100% true, it’s just about convincing the other person that they do?
    Super interesting topic, got me thinking about a lot of things, which is always good! 👍

    I got to call B.S. Having a system where one party dictates the rules and reveal how much information it want to gives is not a breakthrough. Whether you use large prime numbers for verification or any other complex cryptographic technique…etc It all boils down to a lock and key, and whoever has the key dictates “truth”. And what not honest about this subject is getting to ppl belive there a algorithm that knows truth and honesty… no it know its wants to accepts data and to dictate an event base on programed instructions and gives limited data. It could easy spit out lies and be misleading with the same code and one inverse method.

    Sounds more like an abstract way of explaining cryptography. So long as the steps (algorithm) used to compute a statement or problem yield a repeatable or predicable outcome. The steps (algorithms) used to compute the outcome(s) do not need to be known to either partner and can even be different. I suspect this could speed up the computational the required to compute asymmetrical key pairs.

    The problem I have with the “if you can’t explain it to anyone you don’t understand it” is that base knowledge is required to actually understand some things. There is a reason people fail out of physics classes.

    If you are simplifying something you are losing information. If you simplify something enough you aren’t actually explaining the original concept anymore.

    Your example with the College Student is the exact reason why I don’t trust elections and made zero sense.

    Without a more thorough explanation of NP-completeness, it’s explanation-by-metaphor. Here’s my knowledge level: I think NP stands for non-polynomial, meaning it’s impractical or impossible to compute problems of NP complexity beyond a very shallow level. I know that there’s an award for proving that any NP complex problem is equivalent to a P-complex(?) problem, and that doing so would prove that it was true for ALL problems of NP complexity, but I don’t understand how. And I don’t know what “complete” means in this context, although I assume it’s related to the math/comp-sci notion of “completeness”, meaning that your tools or axioms are sufficient to express any mathematical or computational problem or proof.

    So, for me, the child explanation contained the most concise explanation, and nothing that followed added to my understanding.

    not to keen on znp being a boon in the drug example. proving it works without actually divulging what compound it is would be an impediment to science as a whole. Someone somewhere would have to know for regulatory purposes. And therefore one party not knowing would be made meaningless if the information is retrievable should they wish to find out. It’d be so situationally focused that it wouldn’t provide any benefits. I think znp would be good only for truly “need-to-know” cases where 2 parties are involved. A lot of things could use that. But getting down to non-computational things gets screwy. like the voting example. Why would we use znp there? We need the information socially. Otherwise it would eventually boil down to “candidate A won because reason”. Not an inaccurate statement, but not enough information to be truly useful on a grand scale. We’d know that the count was proven to be greater and that all ballots were counted. How many though? For a situation like that folks are gonna want to peek through the window regardless of how mathematically proven the winner is.

    Fantastic video. Got me thinking.

    for every level I was like: Yeah, no, information was definitely passed. Again. And again. No, that’s still information passing through. Up until 18:30 when the last guy makes the distinction between knowledge and information, and that’s when I realized that without this distinction the entire concept doesn’t hold. I would rename zero-knowledge-proofs to really-little-information-and-probably-useless-anyway-proofs.

    Well, if the child has doubts about believing or not that there is a puffin in the picture.

    Why does she accept and believe that the big grey square with a hole on it, it is the same picture?

    Just because she can see a puffin through the hole.

    That grey picture could be completely white and have just a puffin in front of the hole.

    The child will be deceived twice, and no zero-knowledge proof reasoning has worked.

    To be fair, yes, there is a puffin in the small picture that the gentleman shows to the child!

    In the level 2, teenager case, the gentleman is proving to the teenager that he knows the combination to her by opening the safe.
    She does not need to know the combination numbers to verify the original statement of the gentleman, that “he knows the combination numbers of the safe”.
    Therefore a “proof” has been made regardless of whether the numbers of the combination have been revealed or not.

    3rd level. The colouring map will be perfectly arranged only if you have 0.3 bitcoins, right?
    How can you be sure that the student has 0.3 bitcoins beforehand and first at all?
    The gentleman is making an assumption of an unproved affirmation statement.
    Only because it has been stated as an affirmation, does not mean that is true, isn’t it?

  438. JFx Sarmiento

    February 5, 2022 at 12:48 am

    Also, in level 3, the colouring countries of that map have different numbers of “frontier lines” which means that the probabilities to find out the right combination of colour is reduced drastically, as there are only 3 colours and 2, 3 and 4 frontier country lines!

    You can’t replace basic faith with math…it will still fail to bring people together…because mistrust not only has to do with good intent, but bad intent as well. Zero knowledge proof won’t convince those who have no desire to be convinced. Subjective agendas distort zero knowledge proofs just like the media and some scientists distort science. Nice try tho.

The Asian was genuinely in pursuit of further explanation of thought in the field, while the explainer was happy not to postulate but to re-explain the benefits of zero-knowledge proofs.

    Being a computer science engineering student, i didn’t know about ‘zero knowledge proof’ until i watch this. And I believe that everything associated with computer software or virtual technologies, comes with a loophole. No matter how you create or invent new ideas. After knowing about ‘zero knowledge proof’ , I think it will be more dangerous for the internet world. What if this video itself is a ‘zero knowledge proof’ for making you understand that ‘zero knowledge proof’ is a good thing and a lot of data can be secured if you use it. But in reality, ‘zero knowledge proof’ is a harmful thing, like if you consider elections. If political leaders use ‘zero knowledge proof’ to prove that every vote was counted and results have come out legally where actually its completely opposite? Because they used ‘zero knowledge proofs’ to prove it to you. Now lets talk about hackers, what if a hacker use ‘zero knowledge proof’ to prove to you that your data have been hacked and he demands money to let you change all your security passwords and give back your data? Where your computer is completely safe with all your data locked inside. This is my opinion on ‘zero knowledge proofs’. I just told what i think.

    I have a real question regarding level 3 (bitcoin/map/envelope):
    How can the verifier be sure, that the person who what’s to proof something, isn’t only showing what the verifier wants to see? In that case, some random colors which aren’t the same.
    The verifier can’t check if he gets fooled due to the random colors each “check” he gets to not build the entire “map”.

    Hope someone can further explain that to me 🙂

    I don’t like that at the core of this concept lies the fact that human beings don’t trust each other. It’s a good concept, and it’s amazing how it can be used, but I would rather transition to a world where people trust each other than a world where programs bridge a planetary gab in trust. Btw, in these videos, the simplest explanation is always the most complex because information has to be synthesized to a simpler version of itself. Expert level explanations aren’t really explanations at all, but only PHD experts patting each other on the back for knowing the topic so well, and maybe expanding a little on it, but mostly patting themselves on the back.

  516. Ria Linnea

    February 8, 2022 at 5:47 am

    Philosophically speaking, knowledge is a justified true belief so in this instance using ‘knowledge’ instead of data or the other examples given makes more sense. No true knowledge is given because the person who now accepts the fact as true doesn’t have the justification part that having knowledge requires; because they do not recognize how or why it is true, they have true belief with no justification, save for the tiny amount of data supplied. They could never tell someone how or why it is true, but they could tell confidently pass along the data as fact.

It occurred to me that I could write this post in the same manner, seeing if someone would prove to me that they understood it without explaining how, but perhaps that wouldnt generate very many replies 😀 Did anyone else think of this “6th level” of the video?

    It’s really interesting to see how the tone of the interaction changes gradually with each level, and perhaps more noticeable in this clip than other ‘5 levels of difficulty’ clips I’ve seen. With the child, he’s presenting information to her; later on he’s sharing ideas with the expert. And yet in none of the 5 levels is his genuine passion for zero-knowledge proofs lost. Impressive.

    map 3 coloring was perhaps a bad example? In all the other levels he talks about distrust. One simply repeats the same “blue and green” colors to every query a billion times. Confidence of a proof is still 0% if the party doesn’t trust you to give true answers!

    and to prove I know the code, without showing the code is by telling for example the amounts of “w”, where a “g” is located
    or 1245353251 “the sum of this is x” the sum does not reveal the code, but proof that you know the code to a very high probability
    even though this example does promote knowledge, is zero-knowledge proof even possible, even in the child example you give the information that indeed there IS a thing, so it should be called “very small-knowledge proof”

    so the term “as small as possible-knowledge, (yet) proof” is the correct term, zero-knowledge proofs do not exist, if you can proof it to me I will donate you 100€ via Paypal

    Reminds me of doing QC testing. Just do a sample test on a pallet of what you are testing. If a certain percentage passes, then pass that whole stack and gamble the number of failures the customer receives.

    How to accurately gamble the result of random data points without having to test all of the data points.

    I’m a bit skeptic here. That’s too little information revealed by the prover which in turn high chance of manipulation. For example when the guy put the photo behind the board, there is no way the verivier know absolutely that the prover didnt change the photo or just put a puffin sticker behind that board.

    are children her age nowadays really concerned with passwords to login to stuff? /gen

  620. Rasalas

    February 13, 2022 at 11:45 pm

    oooh at the teen level I realized it’s used in hashing (saving passwords in databases* for example) lol.

    *The server doesn’t know the password, but the hash.
    If you know the password you can generate the correct hash – if you don’t you’ll never get the correct hash.

    Simple example of hashing is adding up the position in the alphabet for the full word.
    bubble -> b=2, 16=u, l=12, e=5 -> 2+16+2+2+12+5 = 39.
    I save “39” in my database (not the actual password). If you write “bubble” to login, the same algorithm will return “39” again and I basically know it’s you.

    In this simple case I could try a, aa, aaa, aaaa, aaaaa, … until I get the “39”, but real hashing algorithms are more complex and there are no “collisions”(something that generates the same hash [like 39 times a]).
    Older hashing algorithms like MD5 and SHA-2 do have “collisions” and shouldn’t be used. ATM SHA-3 is used and works differently as SHA-2 and MD5. Until now we didn’t find any collisions in SHA-3.

    (if I miscalculated something it’s the alcohol’s fault 🙈)

    I feel that if you want to show difference in knowledge between a child and a teen. Better get like 8 or 9 years old for child. and like 16 years old for the teen 😀

    So, basically it is a middleman that you have to trust. ?? Just because someone or something is honest about one thing does not mean they or it would be honest about another. There is a higher likelihood, but it most certainly is not a definite.

    The way a zero knowledge proof is defined here implies a zero knowledge proof is circular reasoning, but really the prover does give additional information in the form of showing something new which implies the original predicate is true. So we’ve not satisfied the definition of having “no additional information”. It’s not a direct proof – but not having more direct evidence is not “zero knowledge”. It’s proof by implication I guess. Opening the safe and being able to read the note she put inside -> he knows the combination.
