Advancing OP Stack to ZK Rollup: Achieving Efficiency and Security with Zero Knowled... | Devcon SEA

OP-stack based rollups now retrieve L1-to-L2 deposit transactions and L2 transactions from Blobs. Current solutions face two issues: 1) increased operational costs due to batch submission overhead or 2) protocol complexity during challenges. We'll share our experience addressing these using ZK fault proof. Our new challenge system is cost-free for users and easily extendable to ZK rollups. The presentation includes our example of switching from zkEVM to zkVM and optimizing proof generation speed Speaker(s): TA (fakedev9999) Skill level: Intermediate Track: Layer 2 Keywords: Optimistic rollups, Zk Rollups, ZKP, zkvm Follow us: https://twitter.com/efdevcon, https://twitter.com/ethereum, https://warpcast.com/devcon Learn more about devcon: https://www.devcon.org/ Learn more about ethereum: https://ethereum.org/ Visit the https://archive.devcon.org/ to gain access to the entire library of Devcon talks with the ease of filtering, playlists, personalized suggestions, decentralized access on Swarm, IPFS and more.
