Where Does MEV Really Come From? Revisiting CEX-DEX Arbitrage on Ethereum by Bence Ladóczk, Miklós Rásonyi, and János Tapolcai models CEX-DEX arbitrage in a CPMM setting with stochastic jumps and estimates arbitrage profits that are orders of magnitude larger than those predicted by earlier GBM-based models.
Ethereum's Staking Ratio: The Tipping Point by pintail analyzes how Ethereum's staking ratio surpassed 1/3 due to liquid staking, rehypothecation, and restaking, and argues for adjusting the issuance curve to reduce dilution and preserve decentralization.
Stake-Based Transaction Ordering: A New Experiment on OP Mainnet by Optimism announces stake-based transaction ordering on OP Mainnet, where participants who stake OP receive top-of-block positioning for their transactions.
Introducing Privacy Boost — Optimism's First Privacy Offering by Sunnyside Labs presents Privacy Boost as a regulatory-friendly, high-performant, and composable SDK that leverages ZK and TEEs for private transactions.
Frame Transactions and the Three Gates to Privacy by Toni Wahrstätter describes how Frame transactions could improve privacy and censorship resistance in privacy protocols by reducing reliance on centralized relayers.
Optimizing Besu Performance: Parallelizing State Root Computation by Karim Taam and Améziane Hamlat explains how Besu parallelizes state root computation to reduce Ethereum block processing time by up to 40%.
ETH Rangers Program Recap by Protocol Security Team and Grants Management Team at Ethereum Foundation shares outcomes from the ETH Rangers Program and its 17 security efforts spanning vulnerability research, formal verification, incident response, and more.
A Unified Ethereum Ecosystem. Not a Hundred Islands. Powered by the Ethereum Economic Zone by Kyle Rojas describes how Ethereum Economic Zone (EEZ) reduces rollup fragmentation through real-time proving and synchronous cross-chain composability.
Proof of Time: From Untrusted to Trusted Era by OpenTTT Research Team describes how Proof-of-Time could reduce order manipulation and information asymmetry across domains beyond DeFi.
Mislav Javor published a post highlighting synergies between structured payloads in Smart Batching and universal transport in Frame transactions.
Lumi published a post summarizing proposed upgrades to reduce slot time and finality.
Oisín Kyne published a thread advocating for the inclusion of EIP-7716 in Hégota to increase penalties for correlated validators that go offline.
Indexed Podcast: The Hidden Risks of Crypto Bridges invites donnoh.eth for a conversation on interoperability, bridging risks, and the trust assumptions of cross-chain assets.
Touch Grass Podcast: Privacy Boost ft Karl and Taem invites Karl Floersch and Taem Park for a conversation on the current state of privacy on L2s, and presents Privacy Boost as an SDK for confidential EVM transactions.
