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, MEV/PBS/SUAVE, and much more.

This edition is written by Taiko’s Community Advocate Jünger.

• a16z introduced Losso and Jolt a year ago. Lasso was a new lookup argument with fast proving and Jolt was a zkVM that planned to be built on Lasso. Last week, they announced the initial design of Jolt that is more efficient* than the current zkVMs.

  *Jolt has no precompiles right now. Brendan commented on this issue.

• EIP-3074 got approved to go live in the next Ethereum upgrade! EIP-3074 is gives EOAs smart contract capabilities. This means that it will provide a significant user experience on rollups as well as Ethereum. Cygar shared a high-level overview of 3074.

• a16z published a new study called "Atomic and Fair Data Exchange via Blockchain”. Through this protocol, data behind blobs can be purchased from full nodes. This means that it is possible for a blobs KZG commitment to exist, and it is possible to get the full data behind that commitment.

• Salus Security team shared a study that categorizes vulnerabilities, such as integrity, soundness, and information leakage. The study proposes a comprehensive defense strategy that includes a strong security audit process and a robust network security ecosystem to address the complex and rapidly evolving nature of ZKP implementation.

• Orbiter shared a blog post that explains how Rapidsnarks, a prover written in C++, can be accelerated using Icicle, a GPU library for zero-knowledge proof acceleration.

• The Gevulot team has introduced custom prover sets to enhance the system's flexibility and efficiency. This allows for a modular approach to data storage and the integration of specific external software, catering precisely to diverse user needs.

• Researchers have developed a protocol called 

• Arbitrum BOLD, interactive fraud proofs for optimistic rollups, now live on testnet.

• Aligned Layer (a verification layer) announced collaboration with Ingonyama.

• Optimism shared a blog post on Fault Proof Virtual Machine (FPVM) implementation.

• The Risc0 team shared a blog post explaining why you should choose Risc0's zkVM as your ZK toolkit.

• Reth(Ethereum in Rust) is now in AlphaNet!

• zkSync enabled validium mode on ZK Stack.

Preconfirmation is an early commitment of transaction execution requested by the user and committed by an actor who has a full or partial monopoly on the next rollup sequence. It means that it is possible to provide fast and secure transactions without a centralized sequencer through Ethereum's security.

• Justin Drake gave a presentation on real-time proofing and real-time settlement with zkASIC chips at Ethereum Sequencing and Preconfirmations Call #6.

• Cairo, implemented based preconfirmations by leveraging EigenLayer. You can read the full article here.

• Rohan has published a detailed article on based preconfirmations: Based Preconfs FAQ.

• Wahrstätter analyzed correlated attestation penalties and their impact on today's betting landscape.

• Blob Preconfirmations with Inclusion Lists to Mitigate Blob Contention and Censorship.

• All resources about SUAVE: SUAVE wiki.

• FHE Summit at ETHcc

• The recordings of ZKAccelerate organized by Ingonyama in Athens can be viewed here.
