how improbable does something have to be before its deemed impossible? guessing the correct private key? 2 people creating the same private key in their wallets? 2 people having the same dna in a murder investigation? what are the chances a cat plays beethoven on piano or writes functioning computer code if it jumps on the keys? can the simplest known life form with 531000 dna building blocks containing 473 genes and each dna has 4 letters a c t and g come about by chance even though the possible combinations of dna exceed the number of atoms in the universe? if you see a house do you say it must exist by chance or that it was designed and built by intelligent design even though you never saw it built? did life and the universe come from nothing or from so called quantum fluctuations? "hebrews 3:4 Of course, every house is constructed by someone, but the one who constructed all things is God." is your god chance or intelligent design?

​@@ben-ww7ks Things are only improbable when there are a lot of variants that are picked by one at random. As for the universe - it either was created by god or it wasn't. So from the point of probability it's 50\50. However, the probability that the universe was created by any god humans created in their stories is close to zero.

The risk is not the number of available private keys, it is the random algorithm that the wallet uses to pick one of those keys.

Andreas, you are amazing, always with the best explanations. Thanks for your massive effort to make Bitcoin, the tech behind and the principles, easy to understand. The crypto community owes you a lot.

My favorite video of yours so far, thank you!

Go to the equator and deal a trillion hands. Take a step, repeat. When you arrive at your starting point remove a drop from the Pacific ocean, repeat. When it's empty, refill it and put a card on the ground repeat all. When the cards reach the sun repeat 3000 times, your private key is in there somewhere.

Wow! Mind-blowing! Thank you so much for the explanation!

Enjoyed this lighthearted program. Please do more! 🤣

It was a very similar video many years ago that first attracted me to Bitcoin. Hope this one attracts lots of new Bitcoiners. Very well described as usual Andreas. Would love a follow up with quantum computing. I know you've done some in the past but perhaps one at this basic level of guessing numbers.

Most people use addresses which are 160 bit hashes of public keys. To spend those coins I don't need to know their private key. Any private key whose public key hashes to the same address will do. So I "only" have to search 2^160 = 10^48 = less than one galaxy's worth of silica atoms to steal their money, not the whole universe.

I've got a good one. I did the math on this and this is what I found; Trying to guess a private key, say you could try a key every second and everyone on the planet is too. It would take 75% longer than the universe has existed for someone to guess it. This is assuming of course the are no duplicate guesses.

My issue with this is no matter how slim the chance is, it’s still security through obscurity. A private key should be compared to generating a username, not the password. In that sense, a centralized entity will always have the upper hand due to simply being able to tell you “that username already exists”. Although there are a slew of other problems with central authorities, this is one that simply doesn’t exist for them (all things being equal). It really feels like a practical (hybrid) approach should be taken when considering how keys are generated for your blockchain even though this is looked down upon as not being fully decentralized. That sounds all fine and well until someone happens to get the same seed/private key as you without being nefarious, and there are no protections against it.

@@tradersendeavors School is one body of information, but not the only one can become educated. Who knows if he learnt the math he used to create Bitcoin from school or from other means like books. I’m not against school because it has many positives, being a medium from which you can learn and form an education, but there is a also a negative side to school just like everything in life has. You can’t forget that school is ultimately a business, a business with interests that might not align with yours. For instance it may be more profitable for school to produce students who will become workers rather then inventors, thinkers, creatives, thus they are disincentivised to develop that entrepreneurial side is student who align more to that. This is one example. It doesn’t apply to everyone, but I certainly felt school didn’t develop me in the ways I wanted and the ways I was most strongest at, I always saw it as meaningless and surface-level means to get a degree, to then work for a company. I dropped out of high-school and became a successful entrepreneur. I remember in business studies we learnt nothing whereas now me running my own business, actually learning practically, not just sitting in a classroom, it’s a whole new world.

Oh my. That was mind blowing! How many grains of sand was that again😳 Yeah I guess that drives home the message don't lose possession your private keys.🙂

fokin nailed it :D great job!

My favorite bitcoin Sheldon Cooper. But seriously, very educational as always.

One thing is there is almost infinite number of keys available but another thing is the possibility of the algorithm in charge of generating a key generates twice the same key. i’m not saying it’s very possible but i think the algorithm in charge is very important, must not be poorly designed. In tekken 7 (a fighting video game) when you select a random stage most of the time the same stage appears lol

This was really cool

Fascinating. What about the ratio between the amount of private keys that can be generated in a given unit of time compared to the total amount of possible private keys. Can that be realistically estimated?

This is to get your family/friends off the lottery. Tell them about Satoshi's wallet and that there is a 1 in 2**256 chance they will gain access when they create a new seed.

Possible positions in the Game of Go - 10 ^ 180. So all the atoms in the Universe, with each atom having a Universe of atoms inside it (10 ^ 154) plus change ;)

Can you take a look at the danger of centralization in blockchain staking and compare it with the danger of centralization through bitcoin mining?

What about the checksum that is used in the key, Andreas as surely this would reduce the amount wouldn't it. Actually i'd like to know how the checksum works. No doubt you have a video on that somewhere.

Andreas, if you ever see this, can you describe what you think quantum computing will do to the security of bitcoin and the effect it will have on cryptocurrencies as a whole? I am curious because I think that quantum computers could be used to somehow impact the crypto space given one of its touted applications is the decryption of various applications we consider secure today. If quantum computing becomes ubiquitous and anyone can use it, will that impact the security of crypto? One thing that stands out about bitcoin is that many speculate that its price will just keep going up due to everything that makes it valuable. Could quantum computing impact that?

Interesting. So would I be correct to say that, if you had an industrial size super computer in Nigeria that was crunching out hundreds of trillions of random private keys every nanosecond, this machine would ultimately steal someone's bitcoin at some point. It would be like mining for diamonds, where you crash hundreds of tons of rock for that tiny precious diamond?

Think this' only applicable for a specific phrase, considering how the number of people who gets wallets are increasing. Well, unless they started to use other pool of vocabularies other than BIP 39.
