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.

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
A proposer's perspective on preconfirmations: a new game in town?
This talk will provide a node operator's perspective on the preconf transaction pipeline by examining incentives and infrastructure best practices. Specifically, ways node operators may attempt to earn higher revenues than peers through custom optimizations will be discussed alongside, related risks, and potential mitigations.
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?
Is multi-block MEV a thing? Insights from 2 years of MEV Boost Data
Multi-block MEV describes MEV that arises from one party controlling several consecutive slots. Currently, it is discussed as a potential blocker for several prominent mechanism designs. We analyzed two years of MEV boost data covering more than 5 million slots to investigate historical patterns of it. Amongst other findings we see less multi-slot sequences occur than randomly feasible however that payments for longer sequences are higher than average.
Latency Advantage in CEX-DEX Arbitrage
We study the effects of having latency advantage in the CEX-DEX arbitrage in the first-come first-serve transaction ordering policies. We search for optimal strategies for a trader that owns such advantage. To find optimal strategies, we simulate price changes on CEX using real data and assume DEX price does not change in the latency advantage interval. We find that optimal strategy can even be to trade right away as soon as the price difference crosses a threshold where trading is profitable

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.
