This talk will discuss mehtods to empirically determine the maximal extractable amount of such CEX-DEX arbitrage value in an attempt to measure the upper bound of this LVR problem to date. The video features Ricky Yudhoyaga from Sorella Labs discussing the hidden costs associated with being a liquidity provider (LP) in cryptocurrency markets, particularly in the context of Uniswap's V2 and V3 pools. He begins by explaining the difference between passive LPs and LPs who trade against informed traders, highlighting that informed traders have market insights that LPs lack, which can lead to LPs incurring losses. Ricky introduces the concept of LP's hidden costs or LVR (Liquidity Provider's Value at Risk) and discusses methods to quantify these costs. He details three approaches: a filtered markout based on historical trades, an implied volatility-based model, and a max LVR method. The filtered markout method calculates the difference between the price at which a trade is executed and the price shortly after, adjusted for volume and whether it's a buy or sell. This method also distinguishes between informed and uninformed trades by looking for signals such as high priority fees. Ricky presents data from an open-source MEV classification tool called Brontis developed by Sorella Labs, which shows that LPs have potentially lost over $200 million since March due to not performing proper delta hedging.

ETHBerlin04 May 24-26, 2024, CIC Innovation Campus Keynote: Nick Almond - Building for Big V Value ETHBerlin04 - https://ethberlin.org A Department of Decentralization event - https://dod.ngo The video features a speaker with a background in physics and decentralized governance who has been involved in the crypto industry for several years. He shares his perspective on the current state of cryptocurrency, emphasizing the need to focus on creating value (big V value) rather than just inflating metrics such as token prices and daily active users (small v value). He discusses concepts like Goodhart's Law, which suggests that once a measure becomes a target, it ceases to be a good measure, and how this principle applies to the crypto industry's fixation on numbers. The speaker criticizes the trend of short-termism and the creation of meme coins that lack substantive use cases. He also touches upon regulatory avoidance and the superficial appeal of decentralization, suggesting that these tendencies are steering the industry away from its potential to make meaningful contributions. The talk is intended as a call to action for change, urging developers and participants in the crypto space to prioritize genuine utility and societal benefit in their projects.

ETHBerlin04 May 24-26, 2024, CIC Innovation Campus Keynote: Fatemeh Fannizadeh - We need Censorships ETHBerlin04 - https://ethberlin.org A Department of Decentralization event - https://dod.ngo The video features a speaker discussing the concept of censorship, particularly in the context of Ethereum and blockchain technology. The speaker, who is a Swiss lawyer with an Iranian background, shares personal anecdotes and touches upon philosophical aspects rather than providing legal advice. They explore what censorship entails—limiting access to data—and how it is implemented in various contexts, including on social media platforms like Instagram and in countries like Iran. The talk addresses the necessity of some level of censorship or moderation for societal functioning but emphasizes the importance of individual agency and transparency to allow informed curation. The speaker then delves into how censorship manifests in Ethereum across different layers: consensus, application (dApps), and social. Examples are given, such as validators deciding whether to process transactions from sanctioned addresses and actions taken by various platforms against Iranian users. The core issue raised is who gets to decide what is censored on the blockchain and whether such decisions are democratic or not. The speaker suggests that we should "censor blockchain censorship" to maintain an unstoppable and robust technology. They propose exploring surveillance resistance and inclusion lists as potential solutions to prevent undue censorship on Ethereum. Finally, the speaker calls for every user and application to have the option for curation and moderation, aligning with the Cypherpunk ethos of sovereignty through
