Conditional Recall
In the neon-lit nights of 2025, Johnson & Johnson unveiled X. A pill, not larger than a snowflake, but it promised a tempest of change. This miraculous drug didn't just allow people to cherry-pick memories to erase from their minds, it also can credibly leave a reminder in people's minds that those memories has been vanished, forever. We explore the game theoretic implications of a technology (such as TEEs) that allows players to commit to forget information and discuss several applications.
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.
A Modest Proposal for Ethereum 2.0
Vitalik Buterin gives his talk titled, "A Modest Proposal for Ethereum 2.0"
A DAG-Based Mechanism for Fairer and More Decentralized Reward Distribution
Ethereum rewards validators for their correct and timely votes, incentivizing honest behavior and ensuring security. Although Ethereum has advanced large-scale decentralization, its current mechanism for verifying timely attestations is not entirely decentralized. This presentation highlights a bottleneck in Ethereum's reward distribution that could compromise LMD GHOST security. We propose a distributed DAG-based reward mechanism to enhance security, fairness, and incentive compatibility.
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?
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.
Oracles for number values
We will overview the history and state of research on how to design a cryptoeconomic oracle that outputs a number value. One wants such tools for price oracles, but also for bringing other information on-chain, e.g. the damages to award from an on-chain insurance contract. We will look at approaches ranging from Vitalik's 2014 SchellingCoin proposal to ideas drawing from social choice theory, including based on recent research. We will explore tradeoffs including resistance to several attacks.
