Time is all you need: optimizing Dutch auctions on Arbitrum
Dutch auctions are a common approach in MEV-mitigating mechanism designs. However, little work has been done in exploring optimal auction execution times. Using simulations, we demonstrate how optimizing for a key metric — wait time — can achieve optimal execution without the complexity of existing systems.
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

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
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.
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.
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.
Keynote: The REAL state of L2s
The evolution of Layer 2 solutions has been pivotal in scaling blockchain technologies. This talk, led by L2BEAT founder Bartek Kiepuszewski, delves into the current landscape, recent advancements, and future potential of L2 ecosystems. It will try to address some myths and current challenges of the space. Some important changes to L2BEAT risk framework will also be announced.

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.
