A Modest Proposal for Ethereum 2.0
Vitalik Buterin gives his talk titled, "A Modest Proposal for Ethereum 2.0"
Can we fix MEV?
MEV is problematic today. The MEV supply chain puts centralizing pressure on Ethereum. There’s also an allocation problem; proposers (not apps or users) earn nearly all MEV, though they’re merely protocol agents. Numerous proposed solutions address this (ePBS, EAs, ETs, FOCIL, BRAID...), each with tradeoffs and assumptions about whether MEV is intrinsic to blockchains or extrinsic & preventable. Research is challenging to enter w/o continuous engagement. I’ll provide an overview of the research.
Sybil-Proof Mechanisms
I discuss a fundamental impossibility result on proposer selection mechanisms: If different actors can generate different value from block proposal (or sequencing) rights, the only sybil-proof and incentive compatible way of assigning proposal rights is through an (arguably centralizing) auction. In other words, any proposer selection mechanism can at most satisfy two out of three fundamental requirements: incentive compatibility, sybil-resistance and decentralization.

Based Preconfirmations with MR-MEV-Boost
In this talk, we will analyze a simple strawman setup of based preconfirmations to highlight its challenges, such as supply chain centralization, the lack of pricing mechanisms, and latency/spam races. We will then introduce MR-MEV-Boost, a preconfirmation solution that runs multiple rounds of MEV-Boost auctions within a single slot. This solution addresses the mentioned challenges by preconfirming batches instead of individual transactions and better integrating with the L1 PBS pipeline.
The CBC Casper Roadmap
The CBC Casper roadmap is a plan to implement Proof-of-Stake and Sharding for Ethereum using “correct-by-construction” (CBC) software design methodology. This talk will share new CBC Casper research, including specifications for light clients, liveness and sharding. It will include updates on formal verification and engineering efforts, and a roadmap for (eventual) release.
Evaluating the PBS Experiment: Early insights from MEV-Boost and the Builder Market
PBS is a major change to the core Ethereum protocol. It attempts to minimise negative effects of MEV by delegating block building to a market of block builders. This talk would cover what we have learned from the rollout of mev-boost, focusing on what is happening in the builder market, and what this means for the future of in-protocol PBS. What are the main improvements that we can make to the PBS design in response to how this prototype version is performing?
Next Generation AMMs - Eliminating LVR
Loss-Versus-Rebalancing (LVR) is the most significant form of MEV, yet it has the fewest solutions addressing it. LVR remains a significant challenge for AMMs. This session delves into a comprehensive analysis of how CoW AMM addresses the problem of LVR through its unique batch mechanism. Drawing from 9 months of empirical data, the talk will explore the effectiveness of CoW AMM in mitigating LVR and offer insights into the impact of LVR resistant design on trading outcomes and market efficiency
Agent-based modeling of Execution Tickets
Execution Tickets are currently debated as one of the most promising approaches to streamline incentives at protocol level. We created a holistic overview of potential mechanism designs and implementing an agent-based model to realistically compare different mechanism designs and identify potential drawbacks early on. The agent-based modeling approach is presented together with the results. In the second part, we will guide through running the simulation in the workshop.
Bootstrapping a block builder
The sessions aims to be a practical overview of how to go from zero to having a running and reasonably competitive builder (profits may vary). It aims to answer the following questions: - What software to run? How can this be customized? - What would need to go into writing a builder from the ground up? - How does one acquire orderflow? What is the relative value of various sources of orderflow? - What infrastructure is required? How much does it cost?
