The Rollup Coaster is a bi-weekly newsletter that dives into the fascinating world of Ethereum, exploring the latest in rollups, zero-knowledge proofs, based sequencing/preconfirmations, TEEs, MEV/PBS and much more.

This edition is written by Taiko’s Researcher Jünger.

Highlights 🎢

• Vitalik wrote a new blog post. He says that Ethereum alignment needs to be defined better. He suggests breaking alignment down into things like open-source standards, decentralization, and contributing to Ethereum and the broader world.

ZK and rollup research 🧙

• Flashbots published a research on pricing of blobs.

• Primev published a research on blob pricing in volatile market.

• Steelmanning a blob throughput increase for Pectra.

• Muhammad from Delphi, published a research on transaction ordering policies and value accrual of rollups.

• Espresso shared updates on the decentralisation of Timeboost (Arbitrum’s new transaction order), which it developed in partnership with Arbitrum.

• Joshua wrote a blog that explain some concerns of Arbitrum’s new transaction order mechanism Timeboost.

• Taiko published a blog post on Binius, an idea of building SNARKs over binary fields.

• Argument wrote a blog post about RISC-V zkVMs.

• Telos Foundation shared a new article on SNARKtor, a standart proof aggregation.

TEEs (Trusted Execution Environments) 🫣

• Flashbots is experimenting with Intel TDX to trustlessly capture bottom-of-block arbitrages without exposing frontrunning risks.

• Poetic Technologies proposed the open-source TEE initiative.
