What is Proof of History & How it Actually Works (Animated)

The proof of history is a way of keeping time in a blockchain. the most important thing is that it is not a consensus mechanism. It is a way for leaders to know when to start producing a block, and a way for validators to verify that the leader produced the block in his turn. In this video, we explain what is proof of history, and how It actually works.

So the validator proves that he was occupied fore some time and the logged money could not be used to generate another block. This is super smart and prevents Validators from Validating many blocks with the same money.

nicely done 👍 by far the best explanation of POH

[@Pepote14]

congratulations for this piece of art, it will save a lot of time for people when trying to understand this concepts

[@alanforest7659]

you really put the effort, very well done, thank you 👌

[@sergey_zatsepin]

Thanks! Things start to be clearer

[@parrotfiki]

Your channel deserves more views and subscribers👍 it's the interesting content

[@leetcodeforbeginners]

Best video explaining the concept

[@oinkybob7180]

definitely the best explanation of POH out there.

[@zoechrysostom6463]

Thank you for this explanation. First video that explained in-depth but without being technical !

[@Cryptobie]

We’re glad you enjoyed it!

[@SkullTrapmusic]

Best video explaining proof of history

[@faisalsheikh7846]

Incredible information mam keep it up your video quality and information is phenomenal don't give keep going mam

[@tstone1445]

great explanation

[@valentinfournier7662]

So what happens to the transactions and the blockchain when block 2 and 3 are invalidated ?

[@manirkm1]

Good explanantion

[@coldxois]

thanks

Now im reading about poh and it states that it is a consensus mechanism please help understand this sonce you stated its not

[@alterpub2]

I didn't get the idea why I can't parallel CPU calculations BUT can make parallel GPU ones. If my 2nd CPU thread has to wait for hash #25 to start work, but my 2nd GPU doesn't need it at the same time? That sounds weird.

[@Cryptobie]

The Hashes themselves are calculated with CPU cores, but verified with GPU cores, during verification, the GPU with all its cores have all the hashes already calculated, so the separate cores dont have to wait. But at first during calculating these hashes, each CPU core needs to wait to get the previous hash. I hope that makes sense for you 😀

[@ichristwin]

Finally! 🙇, A video that actually explains PoH. Thank you!

[@akshaypriyal1993]

Very nice video. Well explained!
One suggestion: Please avoid useless animation; it distracts. For example, from ~ 3:30 onwards and till 4:10 or so, the moving magnifying glasses at the top were of no use but were constantly distracting.

[@sv6k0a39]

I still don't understand. Still aped life savings into Solana. 👌

[@m3s69ll]

i get this but isn't this already part of Proof of Work?

[@mounirattieh8122]

right
