Talk 4

Liquid staking derivatives are exciting and powerful, however come with centralization risk and the dangers of holding a derivative rather than its underlying asset.  Validator receipts present an alternative mechanism by which Ether locked in staking can be used as collateral without exposure to derivatives or loss of control of the validating funds.

A highly motivated professional with over 25 years' software engineering experience within the financial industry, Steve has a degree and a Ph.D in Computer Science. He has worked for tier one investment banks across the globe, where his main focus has been on cutting edge derivatives and software to price and manage their risk. Steve is responsible for running one of the largest Ethereum validating infrastructures in the world, and is working with institutional financial firms to make Ethereum

Validator Receipts: an Alternative to Liquid Staking Derivatives

This talk will focus on the future of (de)centralized trading, and examine how frequent batch auctions can revolutionize existing market economics by bringing fairness and protection to Ethereum’s various stakeholders. We will review why Ethereum would benefit from a global batch settlement layer, touching on MEV and unfair pricing of CFMMs.

One Block, One Batch: Examining the Potential of Frequent Batch Auctions in Ethereum

We look at the challenges of implementing various diversity-improving policies on a PoS network. Economic (dis)incentivization is a popular approach, but can be undermined by non-standard miner economics such as (cross-domain) MEV or derivatives on incentivization. As an alternative, we outline an approach to include diversity support into the consensus level without requiring changing the basic functionality of the protocol by adapting the concept of general adversary structures.

Klaus has first started working on Byzantine Consensus during his PhD in 1998, where he build a fully asynchronous consensus layer. He then explored and published in other areas of digital security including secure hardware, privacy preserving technologies, and security for critical infrastructures, before returning to further work on Byzantine fault tolerance. He currently works for Vega protocol.

Beyond Stake: Implementing Diversity Policies on PoS

Solo stakers have a lot on their plate. Keeping up with every single change, how it will affect them and what steps they need to take to ensure their operation runs smoothly is a full time job! In this talk we are going to detail very clearly everything that they should be doing, everything that's coming, what tools and projects are coming to the rescue and what they are expected to do.

He spends most of the time thinking about economics, incentives, ecosystems and outcomes.

Everything a Solo Staker Should Know for the Next Phase of Ethereum

As Ethereum looks ahead to its transition to a fully to a proof-of-stake consensus protocol, the topic of Ethereum’s supply distribution matters more than ever to network stakeholders. This is because under PoS, the amount of ETH users control directly determines how much influence they can have over the network’s consensus building process and the amount of rewards they can earn from staking. This talk dives into how distributed ETH supply on Ethereum has become over the last 7 years.

A Breakdown of Ethereum Supply Distribution Since Genesis

As a nascent field, cryptoeconomics is still lacking in terms of formal definitions upon which a cohesive theoretical edifice can be built. Maximal Extractable Value (MEV) is a particular example of a technical concept where there is no widely agreed upon formalization. Here, we discuss the difficulties in arriving to such a formulation, and survey some proposals. Critically, we emphasize what MEV is *not*, highlighting the critical aspects that need to be encompassed in its definition.

This is not MEV.

MEV has largely been a field where engineering drives science, it’s now time for science to drive engineering: we present an axiomatic formalization of MEV, the theory based on it, and the new applications that it enables.

Promoting Small and Independent Stakers: Q&A with the Ethereum Staking Protocols

Two of the biggest arguments against L2s are that they are breaking composability and interoperability. DApps are deployed as stand-alone apps in each L2 with limited ability to communicate with each other. This leads to silos and several issues in terms of capital efficiency, governance, security, user experience and maintenance.
We will explore how bridges should become the interoperability layer that will connect all the protocol “silos” across L2s, by using secure message passing.

The Layer 2 space moves at lightning speed. Just as we start to grasp a particular concept or protocol, changes and new ideas flood the ecosystem. It is exciting and fast-paced, but it can be difficult to maintain an accurate birds' eye view of current developments and upcoming themes. This lightning talk will quickly survey the Layer 2 field and make some predictions around what themes we are likely to see in the coming months.

Major Trends in the Layer 2 Ecosystem: Where We Are and Likely Upcoming Themes

In the last year we’ve seen thousands of projects and billions of dollars migrate over to rollups. Liquidity and users have started aggressively migrating, but there’s still a long way to go. In this talk we’ll cover successful use cases, pain points that make it challenging for both users and developers to onboard, and emerging projects and protocols in the layer 2 space that are showing a lot of promise.

dm3 is a protocol enabling decentralized, open, and secure messaging based on established web3 services like ENS and IPFS. It doesn't rely on any central service. The user has complete control over where their messaging data is stored. By using ENS names and ENS text records as the registry for public keys, the user owns the identity linked to their messages.
dm3 comes with a reference implementation for a standalone web application, a widget, and a delivery service.

zkEVM Vs EVM: Full Equivalence?

In general, most cross chain use cases are “asset transfer” for bridges to cross tokens from one chain to another then each application deploys the exact copy from L1 to other chains. However, ENS (Ethereum Name Service) has a set of unique challenges because ENS functions as a “global address book” to resolve addresses on any chains from any wallets. We have received lots of requests from chains and dapp developers about how to integrate ENS into their chain of choice and I am going to explain

Bridges are very complex and have under-explored security issues. The issue we are focused on with withdrawing from L2, which requires L1 to be absolutely sure of what occurred on L2 (finality was reached) and current proposals like Offchain Lab’s Arbitrum require 1 week for finality. In this talk, we discuss the three designs for “fast” withdraws that allow a user to move Layer 2 to Layer 1 instantly, while a counter-party takes the risk that the withdraw will not finalize.

The first mainstream uses of zero-knowledge(zk) proofs were for private payments in systems like Zcash and then scalability. In both, we hide data to improve privacy or validation costs. But private payments, unfortunately, have seen limited direct demand. And scalability needs faster proofs but not even zero-knowledge. What are practical zk proofs good for? This talk considers zk proofs + blockchains as a tool both for cryptocurrency and broader applications.

DAOs are cutting-edge organizational structures and there is limited precedent to help DAO stakeholders understand how to operate. DAOs are now starting to research legal, governance, treasury management, tax, and other issues, but much of the foundational learnings of DAO stakeholders are siloed within their own communities.

It’s clear for us now that tokens are the integration point for web3 and token technology should be built around this concept.
