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?

Vitalik Buterin gives his talk titled, "A Modest Proposal for Ethereum 2.0"
Does Ethereum Really Need PBS? Solving MEV at the app vs the infrastructure layer
In this talk, we will give a brief history of MEV (Maximal Extractable Value) and its influence on enshrining PBS (Proposer Builder Separation) into Ethereum. We will explore the Ethereum community’s evolving perspectives on PBS while looking at successful outcomes, unexpected consequences, and alternate solutions. Ultimately, the talk will provocatively ask: does Ethereum really need PBS at all?
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.

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.
Amplifying Consensus Participation with Blockspace Markets
In order to maximize staking participation post-merge, we need to provide capital markets for blockspace demand. This can come in the form of Yield Tokenization (e.g. Swivel, Element), blockspace reservations (e.g. Eden Network), or direct exchanges (e.g. Alkimiya), however composable infrastructure is necessary. With composable infrastructure on the capital markets layer, we can create interesting instruments such as combined staking+lending+options products, and derivative stablecoins.
The Fight for MEV
The Fight for MEV is a talk that focuses on the two most "famous" MEV solutions designs, CowSwap and Flashbots. It will go over the differences in how each model is designed, and why each solution has made those choices (users, objectives). We will end on how we see the future at CowSwap in relation to the merge, MEV, and the overall Ethereum DeFi ecosystem.
This is not MEV.
As a nascent field, cryptoeconomics is still lacking in terms of formal definitions upon which a cohesive theoretical edifice can be built. Maximal Extractable Value (MEV) is a particular example of a technical concept where there is no widely agreed upon formalization. Here, we discuss the difficulties in arriving to such a formulation, and survey some proposals. Critically, we emphasize what MEV is *not*, highlighting the critical aspects that need to be encompassed in its definition.
