    1/15 The scalability of a #zkRollup IS NOT limited by the prove. I'm detecting some missunderstandings of how a zkRollup works. Let me explain in this thread why the prover is not the limiting factor and what are the actual limitetions of zk ( and optimistic ) rollups.

    I'm very excited to present next Thursday at "Polygon zk day" PIL (Polynomial Identity Language). The language we in @0xpolygonhermez created to define the state machines used in the zkEVM prover. People interested can register here: linktree.com/0xPolygon

    Me, together with a core team of 7 developers, just spun off from Polygon to continue the ZisK project as an independent initiative. I’ll remain co-founder and advisor at Polygon, but my main focus now shifts to @ziskvm. Excited for this new era in the blockchain journey β€” we

    1/3 In the last weeks we started the audits for the @0xPolygon #zkEVM . We are also in the final steps before before the launch of what should be the last testnet before mainnet. Here are some of the updates: * Proving time 2.5min in a 7$/h AWS instance.

    We just finished the most important upgrade of the Polygon #zkEVM since the launch. It has not been an easy task. I want to thank you to the whole @0xPolygon team for the hard work. Now it's time for the users to enjoy pairings, sha256, and more. Lets continue scaling #ethereum

    I'm thrilled to have reached this milestone. Nothing of this could have been possible without the zkEVM team and the full support @0xPolygon family.

    Yesterday, I received a prestigious prize from the telecommunications engineering and computer science community in Catalonia. I used my speech to spur the audience to dig into the blockchain tech, as it will change the way humans will organise. Thank you all, it was a honor!

    Today, in the "Polygon ZK Day", I'll explain how we are writing the zkEVM prover. As always, my goal will be to go as deep as I can in 30' but at the same time try to explain it in a way that it's understandable for average engineers. Registrations: linktree.com/0xPolygon

    This numbers are not accurate. You can check this TX: etherscan.io/tx/0x1b899b6ef… Here there are 1116 transactions and the cost is 2.27MGas. And we are not applying compression yet..

    Based on posted tx hashes, ~450k gas for 4 tx in zkEVM vs 1M gas for 512 tx in Era! πŸš€ Note: We're omitting verification cost here.

    This is not only Roman's fight, this is the full crypto industry fight. Privacy is a fundamental value required in the decentralized world we are building. I want to thank you and send full support to Roman and to all the devs and lawyers that are in the front line!
