## Content

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. 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 🎢Yet another SGX vulnerability Last week, a new invulnerability was discovered that allows you to extract the Intel SGX Fuse Key0 aka Root Provisioning Key. FK0 is unique to each chip but the key to encrypt FK0 is not unique to each chip. If attacker found the fuse encryption key (GWK, can decrpyt FK0), they can use it on every chip, as Sylvain said. Also Pratyush wrote an in-depth analysis of the breach. Mark Ermolov @_markel___ Intel HW is too complex to be absolutely secure! After years of research we finally extracted Intel SGX Fuse Key0, AKA Root Provisioning Key. Together with FK1 or Root Sealing Key (also compromised), it represents Root of Trust for SGX. Here's the key from a genuine Intel CPU 4,987 11:49 AM • Aug 26, 2024 Vitalik touched on the fact that modern computing increasingly divides tasks between flexible but less efficient ‘glue’ components and highly specialised, efficient ‘coprocessor’ components, offering advantages in terms of performance, security and accessibility.ZK and rollup research 🧙L2Beat shared a detailed post on fraud proofs.Starknet Bolt update introduced parallel execution and block packing to Starknet.Nil Foundation shared an article on sharding as parallel execution.Ed Felten shared his views on fraud proofs.150 days after Dencun.
