What are Rollups in Crypto? ZKSnarks vs Optimistics Rollups Explained

amazing. thank you.

Good analogies and examples

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?

Smart contracts are not data.

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. ❤

Great overview! Best explanation on the topic!

This channel is really the best channel in crypto.

Great explanation! Subbed :)

So roll ups are batching?

you guys are doing a exelent job, seriously

for building a project on this ZKSnarks will you please guide us what the source to guide us?

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

nice

How are those Rollups different from lightning network?

Hedera Hashgraph already surpasses the scale of visa transactions by 74x more efficient in electricity usage.

great info - i shouldve learned about zk rollups last year but this channel is helping me get over the hurdle

How can we assume that the transactions happened (in case of optimistic roll ups) as valid?
Is there no way anyone makes a fraud?

How is it zero-knowledge if the ZK-Snark checker checks the transaction data?

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.

great job

need more in depth knowledge on zk rollups

How exactly are rollups more advanced than sidechains?

Actually with a parallel computation, 1600-3000 tps can be operated on Zk roll ups .(look at the cryptomonk article on medium)

Hey can you introduce your blonde cousin to me? She's cute.

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.

Probably the best explanation ever.

thannnnk you

Excellent, succinct explanation. I neither yawned nor needed to look at code. Great job.

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 are doing a great job bro

Incredible content - a million thankyous! Distilled down into such a digestible format to make complicated topics actually accessible and understandable! Keep killing it!

The first analogy was crazy understood the basic concept right off the bat! 😅

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?..

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?

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????

No one can beat this style of simple explanation. Simply great!. Your are best Theo.

Thank you for video 🧐

You guys do such a great job… can’t thank you guys enough

Really good content. Congratulations!

very good explanation.

Thank you for creating this content

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?

thanks

Crystal clear to the point explanation. Thank you 😊

great content.

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?
