Talk 5

Interep aims to provide an identity solution for Ethereum users by bridging from an established digital identity source, typically a web2 platform. The product provides an identity layer in an application stack, and integrates with a privacy-focussed layer using the Semaphore framework. Interep can be used to to qualify users, or as an anti-sybil service.

Product Lead with Ethereum Foundation's Privacy and Scaling Explorations group.

Stateless Ethereum: How Verkle Trees Make Ethereum Lean and Mean

Nosy Neighbor was developed as a breadth-first fuzzing tool for the critical golang clients in the ethereum network - Prysm, Go-Ethereum, and Mev-Boost. Nosy is a very annoying (to the devs) tool that aims to find bugs the moment they are introduced. Leveraging the go/types and go/parser libraries used by the Go compiler, Nosy analyzes the AST of a repo and generates fuzz harnesses for continuous fuzzing

Come learn about Nosy's novel approach to go-fuzzing and the issues it has uncovered!

l2beat.com has established itself as the most trusted community resource assessing security assumptions of different Ethereum scaling solutions. Each such solution has a "native" bridge allowing users to move tokens to L2, but there is a plethora of other bridges available to end users. How do they compare to "native" bridges ? What risks users face sending tokens across these bridges ?

Publisher’s Denial of Digital Ownership vs Decentralization

This talks paints a big picture for ETH the asset and its macro cashflows. We discuss unique dynamics arising from:

* **fee burn** (ETH for blockspace payments)
* **issuance** (ETH for validator incentivisation)
* **staking** (ETH for economic security)
* **defi collateral** (ETH for economic bandwidth)

Funding Ethereum with the Protocol Guild

We are seeing the emergence of a specialized role on the Ethereum network dedicated to assembling the contents of each block as the ecosystem grows and the impact of "maximum extractable value" (MEV) becomes clear. This talk investigates block building after the Merge and what considerations the move to proof-of-stake brings to the process along with what norms we should strive for to avoid dangerous centralization pressures while maximizing validator profits.

Alex Stokes is a researcher at the Ethereum Foundation who believes deeply in the Ethereum vision. To achieve this vision, he has been working on scaling R&D to make the core protocol more secure and accessible to everyone. This includes tooling and testing work for the Merge, exploratory prototyping for sharding work like EIP-4844 and EIP-4895 to enable validator withdrawals after the Merge. When he is not working on Ethereum, you can find him at the nearest mountaintop.

Alex Stokes

Block building after the Merge

Maximal Extractable Value (MEV) is excess value captured by miners/validator. This excess value often comes from reordering, censoring, or inserting new transactions that allow a miner to front-run users' transactions. Is MEV *always* bad? Can it sometimes lead to good equilibria for users? We modify tools from algorithmic game theory and probability to prove some surprising paradoxes — *some* MEV improves trading efficiency in networks of automated market makers.

Cost of Feudalism: Towards a Theory of MEV

Scaling blockchains to support billions of users without compromising decentralization is one of the biggest remaining challenges in the crypto space. This talk will showcase why there is a fundamental scalability-dencentralization tradeoff for any monolithic chain, and how scalable rollups on top of decentralized settlement chains can overcome this tradeoff. What implications does this have for the future of Ethereum? Beginner friendly, with pictures!

How to Scale a Blockchain: Motivating the Ethereum Rollup-Centric Roadmap

An overview of ENS's innovations and progress in the last couple of years. Learn about how the ENS DAO is developing new approaches to decentralised governance, and how the development of ENS's offchain infrastructure makes trustless access to data held outside L1 easier for everyone - enabling both ENS's expansion to L2s and much broader applications.

No one expected MetaMask's userbase to grow from 300k to over 30 million during this last bull run. It was an incredibly optimistic time filled with boundless creativity but it was also a chaotic time that led to many having a negative experience with web3.

With the market cooling and the merge complete, let's look at how the early choices at the protocol layer shaped the user experience today and identify what's worth changing for the user experience tomorrow.

The Original Sin

Recursive zkSNARKs are poised to hit production in the next two years. We discuss how to think about the new affordances and potential applications that recursion unlocks for both scalability and privacy. These include proofs-of-proofs-of-knowledge like ETHdos, on-the-fly "programmable" SNARKs, incrementally verifiable computation, distributed proving, and tactics for reducing verification cost or proof size.

Recursive ZK Applications and Affordances

Native account abstraction on L2 is a breakthrough for the usability and security of crypto. It’s also the only way to scale self-custody. This talk explains what account abstraction is and why it matters for Dapps and their users. We’ll provide specific examples of features that it uniquely enables, such as session keys, fraud monitoring, multicall, social recovery and more. The end result is the unlocking of new experiences and use cases that can move the needle for crypto’s adoption.

Why Account Abstraction is a Game-Changer for Dapps

If Ethereum is a digital nation, millions of Africans will flock in masses to become citizens. Why? A fair chance to participate in an open borderless economy, and ultimately self-determination. Web3 is unleashing a generation of African talent trapped within the confines of the old gated economy. A new narrative places Africa differently through the Web3 lens. Why should Ethereum builders take African talent and markets seriously? Where are low hanging fruits for win-win scenarios?

Yoseph is an entrepreneur building at the intersection of Web3 and Africa, and focused on growing the borderless economy on the continent.

He co-founded and was CEO of the Edmund Hillary Fellowship (ehf.org), a community of 500+ top tier entrepreneurs and investors from 68 countries. He built a new immigration program with the New Zealand government, and ran it as a public-private partnership. Yoseph is from Ethiopia, and grew up in East Africa.

Sign in With Ethereum: the Most Powerful Protocol in #Web3?

To maximize the real-world utility of the Ethereum network, ether and ERC20 stablecoins must be increasingly used as money. This means being able to pay for goods and services without going through exchanges or banks. This talk will give a short history of the best efforts so far at onboarding merchants, dive into the anthropological reasons why this is a hard problem, and share our learnings on some recent successes on growing the number of crypto consumer purchases.

Alejandro is a co-founder of the Open Money Initiative and a product strategist at Bitrefill, the world's most popular site to buy real-world goods and services with cryptocurrency, including being able to pay water and electricity bills in El Salvador. He will talk about his observations on the ground in El Salvador, where the average citizen doesn't have a bank account, but does have a mobile phone, and a better-than-average awareness of bitcoin and its benefits.

Schelling-point based oracles, such as Kleros, can be used to attribute soulbound tokens (SBTs) to individuals based on subjective evaluations of their backgrounds and expertise. Moreover, mechanisms using SBTs can complement economic incentives in such oracles; for example, an SBT-conscious random selection process can determine the voters on a given question. We will focus on how the interplay of economic and social elements in such systems can be designed to maximize resistance to attacks.

We will take a birds-eye view of research, industry, and L1 developments on MEV. We start with the reasons behind the origins of MEV, a years-old warnings to developers. We revisit these against an explosion of research and industry interest in MEV. We cover the big picture of why these topics, including PBS, MEV auctions, MEV ethics, "fair ordering", cryptography, etc. are key to the decentralization and UX of L1. We will attempt to provide a roadmap to avoid the centralizing effects of MEV.
