The Rollup Coaster, a bi-weekly newsletter, offers an in-depth look into the latest advancements within the Ethereum ecosystem, focusing on rollups, zero-knowledge proofs, and more. The latest edition, authored by Taiko’s researcher Jünger, is now available, according to taiko.mirror.xyz.

Highlights from the Latest Edition

The newsletter covers several key topics, including:

• Shared Sequencer Debates: Rushi critiques shared sequencers, arguing they are a B2B model, while Jill Gunter counters that rollups do not need to give up their fee revenue. Ben Fisch summarizes Espresso’s objectives.
• Optimism’s Milestone: Optimism deactivated fraud proofs after audits, marking a significant step from Stage 1 to Stage 0. Donnoh raises some questions regarding this move.

Zero-Knowledge and Rollup Updates

• Garaga shares updates on Starknet’s cryptography library.
• The first stage of staking on Starknet has commenced.
• Arbitrum Foundation announces its partnership with Tandem.
• Optimism adds Alt-DA options to OP Stack.
• NEBRA launches its mainnet.

Research and Publications

• Stefanos et al. publish a paper analyzing ZK-Rollups, introducing a systematic methodology for evaluating Layer 2 solutions.
• zkMarek’s podcast explores the concept of trusted setups and their security.
• The Zero Knowledge Podcast, hosted by Nexus, discusses formal verification, Groth16, and IVC.
• Hannes from Equilibrium dives into MPC in a new blog post, discussing trust assumptions and trade-offs.
• Bedlam Research publishes an article on settlement mechanisms.
• Sin7y Labs shares a blog post on optimizing Breakdown in Plonky3 and Binius.
