# The Rollup Coaster #20 By [Taiko Labs](https://paragraph.com/@taiko-labs) · 2024-02-19 --- **The Rollup Coaster** is a bi-weekly newsletter that dives into the fascinating world of Ethereum, exploring the latest in rollups, zero-knowledge proofs, MEV-PBS, and much more. This edition is written by Taiko’s Community Advocate [Jünger](https://twitter.com/Junger0x). Hold on tight! 🎢 _Disclaimer: This newsletter is neither financial advice, nor is indicative of Taiko’s position on any of the material presented. Please do your own research._ * * * **Highlights 🎢** ----------------- * Ethereum’s rollup-centric approach has resulted in multiple independent chains. There is an ongoing debate among researchers regarding whether the shared sequencer and shared prover can resolve this divergence. The main point of discussion is whether the shared sequencer enables synchronous composability. Dankrad argued that using a shared sequencer and prover can achieve this, as stated in his [tweet](https://twitter.com/dankrad/status/1757192131473453374). Furthermore, Justin Drake clarified this matter in his detailed Q&A article, which can be found [here](https://twitter.com/drakefjustin/status/1757348299529437509). * Justin Drake [shared](https://twitter.com/drakefjustin/status/1755929540700807211/photo/1) a photo of the first-ever SNARK proving with ASIC.
