Searcher Competition in Block Building
We study the amount of MEV captured by validators, as a function of searcher competition. The core is a suitable solution concept in this context that makes robust predictions independent of implementation details or specific mechanisms chosen. The surplus share of validators is a function of searcher competition. Searchers can obtain at most the marginal value increase of the winning block relative to the best block that can be built without them. We validate the theory empirically.
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
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.

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.
Comparing Slashing Penalties on Proof-of-Stake Networks
With the support of the Ethereum Foundation, we have performed an analysis of slashing penalties on the seventy largest proof-of-stake cryptocurrency networks. Using insights from institutional economics and game theory, we consider variance in slashing penalties in terms of the conditions that trigger slashing, the magnitude of penalties contemplated, and the limited cases where human judgment plays a role in determining such penalties.
Superliquid Mechanisms for Decentralized Stablecoins
USDC and USDT outpace decentralized stablecoins in large part due to their liquidity. This talk covers the theory, data, and risks of stablecoin liquidity innovations. This will include mint/redemption mechanism design, liquidity pool design, rehypothecation, and protocol-owned liquidity. The analysis will distill how the flexibility of decentralized stablecoin issuance mechanisms can safely be used to their advantage over centralized stablecoins, which Gyroscope v2 is putting into practice.
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.
