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.

Highlights 🎢
- We left EthCC behind last week. There were tons of different events on tons of different topics. The topics currently discussed in the ecosystem were preconfirmations, based rollups, execution auctions and ePBS.
- Based preconfirmations have been a popular topic lately. Without changing the Ethereum protocol itself, it allow users to make transactions fast without being limited to a 12-second block time on based rollups. Based preconfirmations are now live on Helder testnet.
- Starkware’s Stwo prover now can prove 620,000 hashes in a second with Circle STARKs. They measured throughput for proving invocations of the Poseidon2 hash over M31 field on a MacPro M3.
ZK and rollup research 🧙
-
First ZK proof has been verified on Bitcoin with Stwo prover by Starkware.
-
Cysic team shared a paper called “Jolt-b”. The initial Jolt versions had limitations due to their use of Spartan and Hyrax systems, which required complex elliptic curve operations and were impractical for recursive verification. Jolt-b addresses these issues by adopting the Basefold commitment scheme and modifying the Plonky2 protocol.
-
Nexus Labs announced Nexus 2.0 zkVM. This version uses Jolt's arithmetization developed by a16z for the prover frontend. In addition, Hypernova (Nova+Sumcheck+CCS) is used for prover backend.
-
Gevulot announced ZkBoost: Proof Supply Chain Abstraction. The purpose of ZkBoost is to connect all proof networks such as proof marketplaces, prover networks and proof aggregators.
-
Polygon announced new proving system Plonky3.
-
Chainsafe shared a research on GKR, an interactive proof protocol for arithmetic circuit evaluation.
-
Warlock open-sourced new linear algebra library in Rust.
ZK and rollup updates 🗞️
-
Succinct and Nebra announced their partnership.
-
Jolt roadmap update.
-
STRK staking coming to Starknet.
-
Cairo v2.7.0 is coming.
-
CryptoHack(zk learning platform) added new challenges to the platform.
-
World Chain announced developer preview.
-
Reth 1.0.1 is out.
-
Scroll’s mainnet weekly updates.
Based sequencing and preconfirmations 😎
-
Based Preconfirmations with Multi-round MEV-Boost. This research propose multi-round MEV-Boost, a modification of MEV-Boost that enables based preconfirmations by running multiple rounds of MEV-Boost auctions within a single slot.
TEE(Trusted Execution Environments) 🫣
-
teeVM has arrived. Proofcast Labs announced their new RISC-V compatible teeVM. Similar to general zkVM, it’s allow to generate proofs of any Rust/Go/C/C++ code.
-
“Intel TDX Security and Side Channels” research posted in Flashbots forum. The research explains TDX spesific security vulnerabilities.
-
Spare Labs announced the PoC of a framework for creating app-spesific based rollups.
MEV/PBS🔍
-
Primev announced preconfirmations on mev-commit.
-
Searcher Competition in Block Building by Mamageishvili et. al. In this paper, they proposed a new architecture that allows more value to be captured by block building components.
-
Flashbots opensourced Rbuilder, an Ethereum block builder written in pure Rust.
-
ePBS notes #4 by Terence.
