Papers & Articles
- How Not to Be Censored: Inclusion Safety in Client-Led Consensus by Yackolley Amoussou-Guenou and Andrea Canidio derives conditions for guaranteed transaction inclusion and introduces a leaderless consensus protocol that uses block references embedded in user transactions to resolve forks.
- A game-theoretic analysis of the market microstructure in decentralized exchanges with concentrated liquidity by Mikhail Belokon and Rostislav Berezovskiy models LP competition on concentrated-liquidity DEXs, deriving optimal price ranges and showing when volatility makes LP positions unprofitable.
- In-Block Solving on Ethereum by PropellerHeads introduces Fynd In-Block Solver as an in-block re-routing system that recalculates trade routes against the block’s current state to reduce stale-route slippage and reverts.
- Reveal Optionality in Encrypted Mempools Separation, Pricing, and Blind Simultaneous Release with Post-Quantum Time-Locks by Aria Naraghi analyzes the free option to withhold transactions in encrypted mempools and proposes Blind Simultaneous Release using post-quantum time-locks and deposits to commit reveal decisions before other transactions are disclosed.
- Glamsterdam Hard Fork: When Spent Gas Comes Back by ChainSecurity analyzes how EIP-8037 and EIP-8038 could undermine existing contract protections against insufficient-gas attacks, and proposes mitigations to preserve safe failure handling.
- Keep the latest bid, not the highest by Blockspace Forum examines bid selection under ePBS and makes the case for proposers to use each builder’s latest bid instead of its highest earlier bid, allowing builders to lower their bids as market conditions change.
Posts & Threads
- lightclients published a thread reviewing how ChainSecurity’s findings were handled before Glamsterdam’s postponement on Hoodi, highlighting shortcomings in assessing the impact on existing contracts.
- Blockspace published a thread reporting that over 100,000 user transactions have been included through MPBC, with multi-party blocks accounting for 2.8% of Ethereum mainnet blocks in October.
Talks & Discussions

- FRP-XXX: Modeling Cross-Domain MEV Leakage under Concurrent 200ms L2 Native Block Regimes by @saharAP proposes a simulation study of three concurrent L2s with 200ms blocks, examining how latency and non-atomic execution could drive cross-domain MEV leakage and geographic centralization..
- Glamsterdam on Hoodi Postponed by Ethereum Foundation Protocol Cluster announces that the Hoodi Glamsterdam upgrade, previously scheduled for October 26, has been postponed to investigate EIP-8037’s interactions with mainnet contracts.
- Vulnerabilities found in Glamsterdam. Agents came to the rescue. Ethlabs Week 18. by Derek Chiang outlines ChainSecurity’s findings that delayed Glamsterdam on Hoodi, Ethlabs’ coordinated AI analysis to assess upgrade risks, and progress on FCR integrations and recursive mempool aggregation.
