- Full & partial withdrawals to be processed in a single queue-less pipeline
- EIP4844 (proto-danksharding) to be developed on top of withdrawals
- Block value to be added to EngineAPI to allow comparing MEV-Boost vs locally built blocks
- MEV-Boost update
- MEV-Boost:Analysis of MEV-Boost blocks: private transactions (non-public mempool) are 3.8% of MEV-Boost blocksCensorship resistance: define & measure censorship, use collective enforcement (e.g. crLists) and prepare User Activated Soft Fork to force exit & penalize censoring validatorsFlashbots builder needs to charge a fee to increase diversityBulk data export for Flashbots relay

Layer 2
- Vitalik’s proposed rollup milestones to maturity: Stage 0 (full training wheels): on-chain transactions, full rollup node, operator cannot freeze/steal user assets by censoring and no active fraud/validity proofStage 1 (limited training wheels): running fraud/validity proof with security council override and upgrade timelock greater than fraud proof periodStage 2 (no training wheels): two or more distinct fraud/validity provers, security council can adjudicate if there is a bug & provers disagree and upgrade timelock greater than 30 days
