How Bitcoin mining actually works - What is the "cryptographic puzzle"?

In this video I try to breakdown the "cryptographic problem" that people reference when they talk about bitcoin mining.

[@Shokukumi]

"just like my life", hahaha. Well, you made a good video. It's not wasted.

[@Malagent]

Well played.

[@bradvani]

Try repeating that today champ! 🚀

[@rainernaid4378]

@Ahmir Cayden no one cares

[@tamyhope5441]

I died

[@onerealmmapping9199]

Ikr 😂😂😂

[@ArlinMoore]

This is extremely helpful. More people need to see this.

[@looaxe6468]

I must be retarded because what he just said made absolutely no sence. Crypto makes no sense.

[@tomvickers324]

At the end I temporarily went beyond time and space. You explain things well!

[@KeiferKif]

Vishal Jadav those were my two goals, educate and transcend reality

[@tomvickers324]

What are your goals? Planning on doing any more videos? You are great at explaining things and your humor is up my street.

[@KeiferKif]

Kashivre Two thanks! I definitely want to make more videos, I just have to find the time to do all the research and editing

[@finalsak]

Excellent video, you should make more. Your deadpan delivery is just great.

[@KeiferKif]

I too feel I should make more. I need to be less lazy

[@davidweiss5950]

Love your explainer videos. Just found this, I don't know if you've kept it up but hopefully you have! Or shall again. Thanks Keifer!

[@JamesMyddelton]

Best explanation I can find on the Internet. Please keep making these videos Keifer !

[@autohmae]

"leading zeros, because they are before." I LOL'ed. :-)

[@JIANYM36]

8:10 loool love humor or truth disguised as humor. Good vid

[@graciellalee2477]

Just wonderful, I been tryin to find out about "bitcoins" for a while now, and I think this has helped. Ever heard of - Vaneath Crypto Cabotage - (do a google search ) ? Ive heard some interesting things about it and my colleague got amazing results with it.

[@manuelguevara6486]

Good stuff man.. i would suggest you can include more materials, like pictures and stuff but you did a great job explaining it plus that joke was funny haha

[@TheOtrama]

Thanks so much for this thorough explanation. So much better than all the videos that try to explain „Bitcoin in 5 min“. You really touch down on the details.

[@sputniq2828]

You son of a gun. I’ve been reading about this for ages and I definitely understood it enough for convincing bar chat, but I never really got it front to back. I don’t know what it was, something about the way you laid it out it finally clicked. Thank you so much

[@Sinnerrrrrrrrrrrrrrrrrr]

Very informative in simplest way......well done!!!

[@eobardthawne6903]

Oh my brother, you are teaching us all how bitcoin works, you can't just say "just like my life" like that, that's worth millions

[@nickbrown1315]

Man loved it! Keep doing more. The comedic timing caught me off guard 😄 🤣. I was legit trying to expand my knowledge and understanding. Like everyone else LOL, you throw in, like my life... awesome!. Looking forward to more. 💯

[@MikeyKabatek]

Awesome video! I feel like this is great for people who have a good background understanding of Bitcoin, and maybe just not the specifics, and the trippy shit at the end is on point!

[@KeiferKif]

glad you liked it! I was definitely targeting people with a intermediate level of understanding.

[@VIKASGHODE]

U know more than someone else. Please make videos for this reason. You explained it very well. Keep it on. You are simply original.

[@youtubecensorwrongthink5914]

I've seen a lot of videos on this subject and yours really helped a lot. Thank you

[@KP-jx1wy]

Finally a vid that actually explains in detail what is happening. Thanks for the vid!

[@ehcasabianca]

Thanks so much! I had been trying so hard to find out about this mysterious 'puzzle' that the miners are trying to 'solve' to earn bitcoins. You have it so simple, clear, and fun! :)

[@timt.3627]

Keifer, I do not understand how on earth such a great mind only has 552 subscribers on YT. You explain things so well. Your channel needs to be upvoted big time. Love your work! Keep it up. Cheers from Germany ;)

[@KeiferKif]

Thank you Tim! It's comments like this that keep me motivated

[@pandoradespain3119]

THANK YOU I spent like a week trying to find an answer to this question!

[@oroxlaw1534]

Thanks for explaining it so well, I finally feel like I understand it, good job!

[@onerealmmapping9199]

This is prob the most comprehensive video ever. Well done 👍👍

[@GabeHiggins]

WHY... has it taken me this long to find this channel? YES MAKE MORE VIDEOS ON BITCOIN.

[@nithingkoshy]

Watched many videos on the same topics ! Every video had the jargons .. Very well explained !!!

[@tjvdos]

The only video on blockchain that made sense to me. Thanks man!

[@ShyMplsMale]

"They love hash...ing". That was the best lol! Awesome video. Thank you for the hashtastic explanation :)

[@traildataanalytics407]

Superb ! Nice and easy to understand!

[@haydermaha]

This is an excellent video. Thank you very much. Please make more. 👍👍👏👏

[@50hzphotography66]

I love the outro. Great video. I wonder, what determinate how many transactions is included in the mined block? Are those blocks made in the front by the bitcoin software and mining is just making a hash for them so they can be added to the chain?

[@vikram237]

WOW.....faboulously explained !!! great job....

[@nikolaiexplains1771]

Thanks so much. I was looking for a video like that forever.

[@FortyTwoAnswerToEverything]

The missing WinAmp Visualization plug-in's at the end.

[@KeiferKif]

My greatest regret is being born too late to design MP3 player visualization screens

[@GMinihisht]

Great video, thaaaaank you, i miss these old tv b the way

[@hsharma3933]

That small change resulting in a massive difference in the hash, is referred to as the avalanche effect.

[@hristaki99]

I was high af watching this and you really tripped me out at the end. LOL

[@tanzterminator]

Nice explained. Thank you!

[@tejaswiniyella3543]

Very informative and elaborated one

[@asstrix]

Finally I understood what's that puzzle people talk about. Thanks!

[@omsachdev]

Hello Keifer, Thank you for making this video. I, however, still do not understand it quite clearly. Who/what provides that difficult target? is that in a hash format? Where do we get the block header to generate hash value of it? Is it already existing block header or a new one? if it is new one then is it just randomly generated? If you put this whole process in a flow chart then it will make much more sense. My 2 cents

[@DijVids]

This is a great vid. My question (sorry if been asked before) is: If what changes the HASH is changing the inputs within the header (made up of the 6 inputs), you speak about changing the nounce, but nothing else (ie the nounce drives the changes in the HASH) but there is a variable called Time Stamp. Surely that is changing constantly, and therefore you have two variables changing in the HASH Function making it impossible to eliminate / methodically control iterations of HASH calculations? What am I missing? Or does the time stamp just never move?

[@humanrightsadvocate]

Finally an actual explanation of Bitcoin mining!! I knew what a hash function was but I didn't know about the NONCE! That was the thing that cleared everything up! Thank you!

[@yemiolulana5746]

Awesome video man!!!!!!! keep it up.

[@mischa2903]

Thank you for helping me understand the process.

[@nodehead9475]

For a dev this thing is very easy to understand but hard to find on yt

[@Martin-ux8rr]

This... has it all. Thank you for this masterpiece, the randomness I just loved it.

[@vikassharma-lq4bi]

very well explained. Thanks.

[@ThickPeep]

I just found your video and really liked the content! You should consider posting explanation videos on r/bitcoin and r/cryptocurrency I think your content would go great! It's exactly the type of stuff I'd actually like to see and it's the things that can bring more people into the world of crypto because they can actually understand it

[@KLM2020]

thank you for ur effort and time very useful

[@hunterkumarvlogs3124]

Good and informative to know about bitcoins

[@Nacalal]

This was like having your amps wear off half way through a lecture after being up for two days straight. Shit was transcendent.

[@donmon6293]

the best explanation of mining, thank you!

[@TheBestMixBeats]

great stuff!!

[@hsharma3933]

Good work. You explained it well.

[@rootzero6518]

Thanks a lot for explaining. 🙏

[@TheMrAxe0r]

8:00 haha... On the contrary.... you are not wasting your life good sir.. you just learned me something new.. ;]

[@KeiferKif]

Very true! I now have something to live for!

[@nicetry3394]

great video.. awesome..

[@RudraNeupane]

There is something mystical about you and your presentation. I liked them :)

[@johnoh5148]

where did you learn these things Keifer? Is there a book we can read to get more detail on the subject?

[@bionic88]

Thanks for the explanation. That was very thorough... Not sure what the end of the video was about. Can you explain that??? Thanks!

[@TheBeezleInc]

Good explanation. Is there anything in the protocols that say the nonce value must start with 1 and auto-increment? I guess my question is do all the mining computers all run through the exact same calculations?

[@colecramer2683]

Thanks bud, helpful and funny

[@MaxGuides]

But how do you actually turn in your hash once you find it? Where do you get the previous block’s data from? How far behind does this data lag before getting confirmed? If there’s so many transactions how do they all fit on one chain?

[@freshstolencontents3600]

Hello, how can you tell if the block hash is lower than the target hash?

[@road-x]

very helpful, with a sprinkle of good humor.

[@nodehead9475]

Loved it dude ❤️

[@finntiebout8613]

outstanding explanation!

[@acommonlocal]

The award on the wall 😂

[@erezdasa0]

Thank you for this video!

[@tahaniqadi8209]

Veeeeeery nice explanation.. Thank u so much

[@KeiferKif]

Thank you Tahani, glad you liked it

[@andrewhopkins1694]

Very good, thanks!

[@qaislababneh4121]

This is the best description of blockchain I have ever heard

[@mikefreed8439]

"Like my life" was so random and I literally lol'ed and now my coworkers think I am odd.

[@marrsattaxxx]

Awesome Video dude... That 'wasting your life' edit is gold... hahahah... such a funny cut... Nice work man, thanks for helping me understand it... Now I'm off to drop some acid and watch the last 4 Minutes of this video in VR...

[@KeiferKif]

good idea...I should start making my psychedelic videos in VR!

[@LouJunior]

Thanks for the vid!

[@virgo8609]

Great job!

[@sammymuchane6486]

Thanks buddy. This is helpful in better explaining what's going on... B blessed

[@RushitShukla]

very nice explainatory video

[@pdcullippdcullip1892]

Finally a vid that answered the question....thanks Keifer

[@sujith6323]

Great video! . One questions from my side. 1. Once a user submit a transaction, which all data are broadcasting to the network, So that miners can validate and create the next block?

[@rr6620]

8:10 but won’t the time stamp in the header change each time you recompute the hash?

[@khashy87]

when you solve the problem by mining do you just get a meaningless answer ( the input) is it random numbers and letters or characteristics?

[@cjax235]

Excellent. Thank you. A rare gift of turning the complex into basic

[@ricardoshane4401]

*Yeah! *Contact mattobrown on telegram for your pipes and plugs*

[@amnsinha]

I am studing blockhain and i know that a block hash is linked to the next block in previous hash and it cant be changed for valid reason. Reason is : because if someone have changed hash then then he/she would have to change in hundreds or millions of nodes/system also otherwise it wont be valid. My question is : If nonce will be changed by some miner then the hash will also get changed and it should be changing the next block's previous hash. correct me if i am wrong. I mean if a miner can change the hash of a block then how he can replicate that hash in all the nodes or system for that block? this is confusing.

[@iamlove7096]

Thank You...its still difficult yet it helps a lot

[@thevendetta9726]

I love this dudes hidden humor hahaha. But he explained this concept really well. The way he is talking to the camera in person sometimes not sounding 100% sure himself lets you emphasize with ihm more which i kinda like. Other explanatory videos often sound like they understand the concept themselves so well and make you feel really stupid for not understanding it right away. What I also liked is that he immediately addresses the stuff you would ask yourself while listening to concepts like these. For example when he talked about performing the hash on the block header to sovle the problem, I asked myself how they can find a smaller number when the hash is always producing the same shit? He immediately refers to the Nonce at the end of the header which I liked. Other videos often forget these kinda stuff and you are left to research or google it yourself.

[@random2059]

sir i have questions.... please reply ... if all minners are fighting for the #right #hash by possibility checking ...which one is right .... !!! then how is the mastermine who already decided the #ANSWER i.e a specific 64 character answer,who also decide the if the if that specific 64 is achieved by any one ... congrats he is the winner... who is the mastermine ...

[@MJVelascoSalvador]

Hi, at 6:58 you said there are 6 things... but I only took note of 5 Version, Timestamp, Previous hash, Merkle root, Difficulty Target. Did I miss anything? Sincere question as I am researching on the topic. Thanks

[@MJVelascoSalvador]

I see, I think you mentioning this was preemptive for the Nonce. Am I correct?

[@Royorg-qf5jq]

How does them mining pool work with shares?

[@ngocson2606]

Thank you for the video. I have one question: Why are you hanging Ho Chi Minh portrait on the wall?

[@KeiferKif]

It was from a trip to vietnam. it's not up anymore

[@sumukhasureban8249]

can anyone tell why difficulty target is set......pls

[@cryptoconversations388]

Outstanding

[@kalyanchakravarthigunda4335]

Thanks for the Video.. Could you please explain more about Digital Signature algorithm used in Bitcoin.

[@KeiferKif]

I understand the general idea of a digital signature, but not enough to answer your question. I'll put it on my list of video topic ideas

[@matthewelliott5118]

Thank you. Bitcoin been out awhile. I been resistant to even investigate. You answered almost all my questions. But how does this activity generate something of value that earns a reward that's also valuable?

[@YrejEq-gm2ew]

I love learning.

[@alisonagley5805]

You're awesome! Please make more videos :)

[@JK-de1oy]

"They loved hash"

[@jakedevries1455]

i thought I knew all about extracting 'hash' but it turns out I don't..... 😂

[@Yewbzee]

Great video thanks. However after being mesmerised by the psychedelic colour scope at the end I snapped out of the trance 6 hours later with no memory of any of it.

[@KeiferKif]

No conscious memory* you could have some subconscious memories I planted

[@WestCoastAce27]

Great job. Very clear. But a few questions if anyone is still watching the comments: 1) I heard that a typical ASIC miner has 43 separate chips each performing a hash. If this is true, obviously having each iterate the nonce 1,2,3… would be useless. So is there software that coordinates the chips’ nonces? 2) And then if 1 own 50 miners, how would the nonce coordination be done across all the mining rigs? Thx in adv.

[@Travel_fulltime]

I understand mining perfectly but I’m Tryna figure out what happened to your screen at the end LOL
