Papers & Articles
- How to Serve Your Sandwich? MEV Attacks in Private L2 Mempools by Krzysztof Gogol, Manvir Schneider, Jan Gorzny, and Claudio Tessone study the feasibility, profitability, and prevalence of sandwich attacks on rollups with private mempools, and find them to be largely absent.
- Synchronous Composability Between Rollups via Realtime Proving by Jordi Baylina explores how based rollups could achieve synchronous composability by posting the DA payload and the validity proof as a single atomic unit.
- New Directions in Synchronous Composability by Jason Vranek analyzes Vitalik Buterin’s post on Combining preconfirmations with based rollups for synchronous composability and compares it with other existing designs.
- Post by Jason Vranek
- Application-controlled execution: A case study on cancel prioritization by Mike Neuder and Maryam Bahrani analyzes four proposed mechanisms for implementing Application-Controlled Execution (ACE), and how each could instantiate cancel prioritization.
- Early Rejection of Adversarial BALs by Toni Wahrstätter describes how the current BALs specification may introduce an exploit to force unnecessary work during block validation, and outlines a mitigation through a gas-budget feasibility check.
- Failure modes in EIP-8037 and state-gas scaling by Anders Elowsson review two equilibrium failure modes that arise in EIP-8037 and outlines corrective state gas scaling measures that can be deployed.
- Ethereum’s Post‑Fusaka Activity Surge: The Impact of Address Poisoning by Tanay Ved analyzes address poisoning post‑Fusaka on mainnet, and estimates that it accounts for 11% of transactions and 26% of active addresses on an average day.
- zkFOCIL: Implementation & Benchmarking Report by Shreyas Londhe and Suyash Bagad documents the implementation and benchmarking of the Linkable Ring Signature (LRS) scheme proposed in zkFOCIL, comparing prover and verifier performance across different proof systems, curves, and backends.
- Hegotá Should Complete the Holy Trinity of Censorship Resistance by Luis Bezzenberger argues that Hegotá should include both FOCIL and Universal Enshrined Encrypted Mempool to deliver strong inclusion guarantees and censorship resistance alongside ePBS.
- Native Account Abstraction: State-of-Art and Pending Proposals (Q1/26) by Mislav Javor outlines four proposals to achieve native account abstraction: Tempo Tx, EIP-8130, EIP-8141, and EIP-7701, and compares them in terms of gas sponsorship, batching, passkeys, and post-quantum readiness.
- The Option Value of Waiting in Prediction Markets - A structural theory of volume timing, entry timi by 0xnagu presents a framework for distinguishing whether late trading volume in prediction markets arises from delayed information arrival, or adverse selection that discourages early entry.
