Thanks for watching!

[@millionerbbb]

Wow! Huge thank you for all the info!

[@surojeetghosh237]

Nice explanation + tutorial

[@SZakiabba]

Did Polygon zkEVM encounter any issues or security vulnerabilities? I would like to write a research paper on it

[@justiceessiel6123]

super cool

[@nachobatero]

thankyou thankyou and thankyou

[@Alex-tsao-timi]

Hi, this is a great video to understand Polygon zkEVM, thank you for sharing! One question I have is that it seems that you can see transactions details through zkEVM Polygon scan, maybe this is very basic, but I thought all transactions with zk proof are completely private 😆, I think I miss something here, appreciate it if you can help shed some light on my confusion, thanks

[@JarrodWatts]

Thank you! ZK proofs have applications for privacy, such as hiding aspects of your identity. However, zk rollups don’t use them for privacy. Each transaction is completely visible on L2 and also gets sent to L1. They use ZK proofs to verify the validity of batches on Ethereum.

[@hyochanjang]

Do we have any mobile SDK for zkEVM to use in native app (Such as React Native)?

[@JarrodWatts]

I've been experimenting with thirdweb's React Native SDK portal.thirdweb.com/react-native

[@circleofblessing9580]

Is react query not better instead of the useState from thirdweb?

[@JarrodWatts]

You can use both - the ThirdwebProvider accepts a prop where you can pass your own react query stuff in

[@dev.soniabatista]

How can I add a Polygon zkEVM Cardona in the chainlist of thirdweb?

[@ChapperorYapper]

did you get any workaround

[@soniamarabatista77]

@@ChapperorYapperNo, I didn’t

[@justiceessiel6123]

so is zero knowledge more for scalability or proofing without showing the real thing or both

[@prontomatias3081]

The concept of zk its the proof of something even if you dont have the full knowledge of what is being proven. You still can reliably trust that proof that was provided.
The ZK proofs allow L1 (ETH) to trust L2 (Matic) and vice versa, this means that ultimately L2 will take the burden out of L1, so it makes it more scalable (throughput).

[@prontomatias3081]

I believe L2's magic its in using ZK proof of batches of transactions opposed to a single transaction in L1

[@ChapperorYapper]

seems outdated can't run yarn deploy

[@GayathriP-sw1jw]

@ChapperorYapper
Ive been getting authentication request from thirdweb dashboard when i do npm run deploy. So when i sign via wallet to authorize, it goes "Something went wrong! Unable to authenticate with the dashboard." Tried a lot of times from different browsers,the issue persists...is your issue the same?

[@miodas4559]

Do we have any updates on zkEVM? I can't seem to find any recent news about the project. Considering the significant funding it received, it's strange that it would just disappear like that.
