Time is all you need: optimizing Dutch auctions on Arbitrum

Duration: 00:00:00

Speaker: Alan Wu, Brad Bachu, Cody Born

Type: Lightning Talk

Expertise: Intermediate

Event: Devcon

Date: Nov 2024

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.

Empirical analysis of AMM loss versus rebalancing on layer 2 chains

This talk presents an empirical analysis of Loss versus Rebalancing (LVR) on Arbitrum, Base and Ethereum. It compares the realised and theoretical LVR; along with the arbitrage profits from CEX-DEX/Perpetual; then further reveals whether the frequency of delta-hedging, the pool liquidity and the block time difference lead to better or worse LVR.

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.

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.

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

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.

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.

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.

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
