What is Hashing? Hash Functions Explained Simply

Classrooms don't have music playing while instructor is talking. Why would an instructional video have background music?

So fucking cool

intro is so damn satisfying

very good and concise

Great explanation! The animation was super helpful.

Great explanation thank you!!!

Awesome explanation, thanks! Now I understand a little more about the blockchain 😁

Immutable was my past concern, now im all in.

Thank you, this explanation is so good for beginners and non-specialists to understand

Are there more than one Blockchain in existence, or is there just one? If I enter a unique list in the blockchain, and receive a hash, and a year later someone I do not know on the other side of the world enters the exact same list, will “the blockchain” let them know that list has already been entered and provide to them the same hash that I received?

found this one helpful after going through 10+ tutorials.

Perfectly concise video! Thank you.

Omg thank you this was so simple

What's the music in the background?

First time viewer and subscribed 🤗

Interesting stuff

I love how it explained how blockchain uses hash to generate hash in many rounds to make it secure.

Thank you very much

awesome

Good explanation. The first thing I wanna correct is, hashes don't necessarily need to be fast. There are hashes that are deliberately slowed down by design to avoid rapid brute force. A few milliseconds delay isn't going to cost a lot for genuine users, but it will definitely hurt if someone is generating a billion of them. A hash that is too fast may not be the best candidate after all. Next, it is possible to find two different inputs with the same hash due to hash collision. In fact, there are infinitely many collisions for the same hash. Also, you forgot to mention the importance of the distribution of the hash values. It should be mostly uniform. This is to make sure, it helps in collision avoidance and not cramming a specific subset (range) within the space attracting the attention of the attackers.

came for hashing,stayed for blockchain

Fantastic explanation and excellent video quality.

Absolutely brilliant video. Subscribed!

Dogecoin bought me here

Wow, That video just blew my mind and made me learn Way more than What I thought I was going to learn, and in less thanin three minutes. Insane!

Thanks for the video very much, it helps me understand what hashing is!

It is nearly impossible to find any tutorials or instructions on how to create a source video hash. This video was however an outstandingly concise explanation of what the heck blockchain is. Sigh.

Oh Lisk ....still so undervalued !
I bought lisk 4 yrs ago

Impeccable animation.

Thank you! Great simple and easy to understand video.

This is the mot educative video in the world

nice i will pass now

And then came Quantum Computing...

Superb! And also explains intro to blockchain.

nice

Really great 👌👌👌

I decided to give the like to this video within the first 10 seconds. I didn't have to think it that much.

clean videos are awesome

Hi, where can i find a book about Hashing?
