The Latest Innovations in Ethereum Explored in The Rollup Coaster #29

Rollup Coaster, a bi-weekly newsletter, takes an in-depth look at the latest developments in the Ethereum ecosystem, focusing on rollups, zero-knowledge proofs, and more. The latest version, written by Taiko researcher Jünger, is now available, according to taiko.mirror.xyz.

Highlights of the latest edition

The newsletter covers several key topics, including:

• Shared Sequencer Discussion: Rushi criticizes shared sequencers, arguing that they are a B2B model, while Jill Gunter counters that rollups don’t require giving up commission revenue. Ben Fisch summarizes Espresso’s goals.
• Milestones of Optimism: Optimism marked a significant step from Phase 1 to Phase 0 by disabling post-credit fraud proofs. Donnoh raises some questions about this move.

Zero Knowledge and Rollup Updates

• Garaga shares updates to Starknet’s cryptographic library.
• The first phase of staking on Starknet has begun.
• The Arbitrum Foundation announces a partnership with Tandem.
• Optimism adds the Alt-DA option to the OP stack.
• NEBRA launches mainnet.

Research and Publication

• Stefanos et al. published a paper analyzing ZK-Rollup, introducing a systematic methodology to evaluate two-layer solutions.
• zkMarek’s podcast explores the concept of trusted settings and security.
• The Zero Knowledge Podcast hosted by Nexus discusses formal verification, Groth16, and IVC.
• Hannes from Equilibrium dives deeper into MPC in a new blog post, discussing trust assumptions and tradeoffs.
• Bedlam Research published an article on payment mechanisms.
• Sin7y Labs shares a blog post on how to optimize Breakdown in Plonky3 and Binius.
• Erik Kadena of RiscZero discusses the evolution of Rust within zkVM.
• Timofey from Chainsafe takes a closer look at Circle STARK in a blog post.
• Ingoyama publishes a new chapter in the NTT201 book introducing ANTT (Count Theoretic Transformation).
• Guangdao introduces a novel method for constructing non-interactive zero-knowledge (NIZK) proof systems in the post-quantum home.

Base sequencing and pre-checking

• Eli5DeFi builds a sequencing-based ELI5.
• The recording of the sequencing, pre-confirmation, and promise of the “Cake Day” event has been released.
