- Rollups are way to "roll up" a bunch of transactions into one single piece of data to save space and processing power on the blockchain. Right now, there are 2 main rollups: ZKsnarks and Optimistic rollups and you can watch our video to learn how both work, including the benefits and drawbacks.
This channel is an absolute treasure trove of knowledge. Literally a one-stop shop for all things crypto. Thank you so much. I cannot believe this is free
By far and away the best explanation of this stuff that I've come across. Thank you!
No one can beat this style of simple explanation. Simply great!. Your are best Theo.
The best video on TH-cam explaining what ZK Rollups are! Thanks! Like always everything clear.
Excellent, succinct explanation. I neither yawned nor needed to look at code. Great job.
Awesome 👏 I have watched a lot of videos about rollups on TH-cam. I can say this is the best video of rollups on TH-cam 👏👏 Awesome. Simply explained what it is on a base level in a way that can be understood by anyone 👏👏
Great video! This is the only crypto youtube channel that I understand.
This channel is really the best channel in crypto.
Amazing Explanation bro.. Taiko takes it a step further with rollups that not only prioritize scalability but also boast a shared DA layer. This distinctive approach enhances interoperability, setting Taiko apart in the evolving blockchain landscape.
A very simple explanation of how zk-rollups work. Good work
There are interesting projects under development such as zkSync and Polygon zkEVM that I think can be really relevant to grow the whole industry.
amazing video , been watching your videos since last 2 years and still no better videos till this day explaining concepts in such easy way. Just one thing that i think you should also add documentation and papers you used for research .
AMAZING AMAZING AMAZING WORK
damn!!!! i have been really confused about this rollup stuff, everytime am doin a research they pop up. thanks to this channel for helping out.
You explain it so good now I want you to make videos explaining everything in my life to me
Where does loopring(LRC) fit in to zkrollups?!
i love how you explain. even a child can understand ❤❤
great info - i shouldve learned about zk rollups last year but this channel is helping me get over the hurdle
Incredible content - a million thankyous! Distilled down into such a digestible format to make complicated topics actually accessible and understandable! Keep killing it!
Excelent explanaition. Would love to have a written version of it, maybe on a whiteboard crypto blog? Sometimes I find it useful to read after/while I see a video to fix an idea on my mind
Thanks a lot!
The first analogy was crazy understood the basic concept right off the bat! 😅
Crystal clear to the point explanation. Thank you 😊
Your channel is amazing and still very very undervalued for the caliber of content it provides. Imamazed, cheers from Colombia, regular viewer and learner. Hope this project keeps growing and the motivation to do such easily digestible videos just keeps on growing because the way you make us understand all this crypto complexity is amazing.
Great job on this one. I’m doing a Wharton Business School course and needed some help understanding these specific points. You did a better job than the video they sent me to.
your the goat bro. cant believe your only 24. keep it up man
Probably the best explanation ever.
You guys do such a great job… can’t thank you guys enough
Best Explanation on ZKSnarks and RollUp
you guys are doing a exelent job, seriously
Best channel for real knowledge 👍
Very concise and informative! thanks!
Amazing video, it would be really helpful if you dig deeper and explain the level zero of it, I mean what technology is used for rollaps... and how exactly thay're been sent and validated...
Your videos are amazing - keep them coming!
Great overview! Best explanation on the topic!
This channel is so valuable
Sir please make vedio on roll-ups vs bitcoins lightening network 🙏🙏
I love your channel. I would like to request you for a Solana Proof of History part 2.0 video, which you promised to make in part 1 video. Thank you.
Just a situation-
In optimistic rollups if everybody thinks that somebody is checking, but as everybody thinks so, nobody is checking in reality.
So what may happen if nobody is checking but transaction gets approved as everybody thinks that a certain transaction is valid because somebody may checking?
Not sure, but my question sound's too funny. But definition love to get an answer.
i barely undestand all of this tech but i prefer zk rool sound much more effective
Thanks for the effort, it's really helpful.
Another great video!
Good analogies and examples
Brilliant video! Thanks :)
very good explanation.
you are doing a great job bro
Awesome, I want to understand is:
How can we effectively use rollups?
What are some of the networks that work as the 2 layer solution?
What I see is, rollups could effectively decrease the cost of transferring Ethereum, but how can I transfer Ethereum using it, to reduce my costs.
If you’re familiar with the DEX, DYDX, they use rollups in order to give you the same feeling as a centralized exchange, but with far cheaper fees, compared to Uniswap which does not use rollups and is on L1 eth. (Although they will be implementing a L2 soon)- I hope that helps.
Actually with a parallel computation, 1600-3000 tps can be operated on Zk roll ups .(look at the cryptomonk article on medium)
great content.
Quick question - when you mention that its added in the "data" portion - how does that work? can those rolled-up transactions be easily read just like a normal transaction?
Great explanation! Subbed :)
Still loving your videos :-D Question - Timepoint 4:46 - How does basically outsourcing the computing of one task to another computer do anything other than making the work of the main network faster/less burdoned? I´m really thinking regarding the idea of ETH 2.0 being more environmentally freindly on layer 2 - since you say that this is what the layer 2 scaling solution does. Seems like a lot of computing power is still burning up power
need more in depth knowledge on zk rollups
5:11 The ZK *prover* (the scaling solution) does need to see the transaction data when creating the validity proof. 'Zero knowledge' pertains to the fact that the ethereum network does not need to know the nature of the transactions to deem that the validity proof data (to be applied to the EVM) is valid. That is, Ethereum is a ZK *checker*.
Hi mate, informative video as always. Mind if I ask, what about ADA relative to this topic? From my understanding, ADA doesn't need Rollups because it has implemented the solution to scalability far ahead in its creation? CMIIW and thanks mate!!
My understanding: if ZK rollups work, then they will scale far better than Cardano or even Solana on their best days.
I still don't follow why: if a rollup contains 10 transactions then wouldn't the size of the data be 10 times the size of a regular single transaction and so take up the space of 10 transactions anyway?
Thank you for creating this content
Really good content. Congratulations!
great job
Hello! Please make a video of the new Hybrid rollups that is still developing at this time, I want to know about this projects. thanks in advance. ❤
Thank you for video 🧐
Now I understand Loopring!
good stuff mate
been in the "industry" and let me tell u I like the content. keep up
You mentioned that in optimistic rollups if the transaction is fraudulent then the validator is slashed, but before that you mentioned that there is no validator and we consider all transactions as good. So how does that work? Who is slashed?
amazing. thank you.
Thanks!
Brilliant channel
Fantastic work as always!
How are those Rollups different from lightning network?
How is it zero-knowledge if the ZK-Snark checker checks the transaction data?
These videos should be used to teach teachers how to teach LOL
Can you explain rollup for me a bit more plz? I’m kinda confused. If you make 1000 txns on the roll-up chain and settle that 1000 txns on the ETH chain, how are you avoiding paying gas fees for the 1000 txns being settle eventually on the ETH chain?
If there will actually be only 1 txn being made on the ETH chain for that 1000 txns made on the rollup chain, how does security exactly work for each transaction on the ETH chain? How are the 1000 txns exactly confirmed and secured at the transaction level per ETH addresses? Are there 1000 ETH addresses involved?..
🔥🔥🔥🔥🔥🔥
Phenomenal work.
Hedera Hashgraph already surpasses the scale of visa transactions by 74x more efficient in electricity usage.
for building a project on this ZKSnarks will you please guide us what the source to guide us?
thank you for the great explanation
I am gonna write a letter for the dog too😅
talented man, where do I support?
Subscribe and watch other videos 😍
Waiting for a ZEC video...
How can we assume that the transactions happened (in case of optimistic roll ups) as valid?
Is there no way anyone makes a fraud?
thanks
thannnnk you
So roll ups are batching?
Can you use this compare the solutions offered by Zksync and Celer Network? Both of them are rollups.
Why a lightning network is not a roll-up? Don't they do the same thing? Take a bunch of orders and execute them only once at the same time to save energy?
why will an optimistic rollups validator will get slashed on a fradulent transaction detection , as he simply does the rollup of all the transactions he got and haven't verified it at all as per the optimistic protocol????
hi. i wanted to ask if the rollups when submitted to the layer1 will through the validation process of POS. i.e having a random block proposer run through the process of validation before being added to the block
How exactly are rollups more advanced than sidechains?
nice
so what happens when eth 2.0 comes, will we still need them?
🔄 While the discussion on Bitcoin rollups unfolds, Taiko's ZK-Rollups bring a unique blend of scalability and Ethereum compatibility.
With efficient throughput and minimal data transfer to L1, Taiko offers a promising solution for the broader blockchain ecosystem.
🚀✨👍
grat video
This is the Issue with ETH. As a software developer its horrible but for the average business man you can't ignore the money that is locked in this network but that does NOT make it a good network
👍🏻
Keep up the good work guys!
Another good video. Thanks for sharing
I would love to hold and invest in Whiteboard Crypto knowledge coin supporting your free knowledge which is worth more than Gold
If i could put them in a pool which transactions fees used to support u creating the video would be amazing
Governance use of Voting on Video topics also interesting.
AMAZING CONTENT! Keep it up! :)
Smart contracts are not data.
💚 ETH to $27,000 in 2022
Thanks again guys for the video, that is really helpful! I really love the first part of sending letters in one big fat envelop analogy! in few seconds my brain just understand what rollup is in a big picture ( have been reading many articles about it but keep yawning before I could understand a thing =)).. but would optimistic rollup kind of risky though that you are trusting everyone's work without further check or validation?
