Keynote: Unifying Ethereum Through Intents and ERC-7683

Ethereum has scaled with a diverse ecosystem of L2s—but this created a new challenge: how can this fragmented landscape of potentially millions of rollups feel like a **unified Ethereum**? In this talk, I’ll discuss how intent-based architectures—and new standards like ERC-7683—can help unify Ethereum while maintaining the benefits of Ethereum’s rollup centric architecture.

Beyond recursive proving for Starknet

Recursive proving is very cool tech enabling very large proofs or combining many different statements into a single proof. Beyond recursive proving, statements can be combined in interesting ways to further reduce system overheads such as data availability compression and layer1 state updates as well as various privacy concepts. In this session we'll discuss some of these technologies and how they are being applied in Starknet to achieve various user and system benefits.

A Revenue Model for Based Rollups

We outline the costs that a based rollup has, followed by the paths it has to revenue generation, revenue capture and finally revenue redistribution. We demonstrate that based rollup costs are front-loaded and non-negligible. Based rollups must pay for ZK-provers, app- and user-onboarding, R&D, etc, as well as L1 fees. We consider several continuous and once-off revenue models, and compare the pros and cons of each according to several key properties that based rollups are expected to have.

Advancing OP Stack to ZK Rollup: Achieving Efficiency and Security with Zero Knowledge Proofs

OP-stack based rollups now retrieve L1-to-L2 deposit transactions and L2 transactions from Blobs. Current solutions face two issues: 1) increased operational costs due to batch submission overhead or 2) protocol complexity during challenges. We'll share our experience addressing these using ZK fault proof. Our new challenge system is cost-free for users and easily extendable to ZK rollups. The presentation includes our example of switching from zkEVM to zkVM and optimizing proof generation speed

Decentralize your sequencer -- A guide for L2’s

This talk will act as a river guide exploring the design space for L2 sequencer decentralization. It will cover: 1. Should L2’s care about decentralizing a sequencer? 2. What does it mean for UX? 3. Forced Inclusion ≠ Decentralised sequencing 4. ELI5 the approaches being taken by L2's 5. Based rollups to the rescue? 6. What are for optimistic / zk and / privacy rollups 7. L2 Consensus networks are not the solution 8. Decentralisation is not just about sequencing rights

Public-Private Hybrid Rollups

We posit that it is a best practice that rollups have privacy capabilities. We'll focus on zero-knowledge and its role in enhancing privacy and how to deal with the need for public state for shared use cases. We'll delve into the interaction between public and private execution environments, detailing how such disparate execution environments can be combined.

The rise of Appchains: from L2s to Rollup Clusters

Ethereum's rollup-centric approach has led to the emergence of L2 Rollup Clusters reducing fees but creating fragmented liquidity and a less seamless user experience. Third-party bridges, though helpful, are cumbersome, vulnerable to hacks ($2B losses to date), and costly, leading to high fees. In this keynote, Alex will discuss how native interoperability, with ZK at its core, can resolve fragmentation, enabling Clusters to collaborate instead of competing for users and liquidity, ultimately dr

The Three Transitions: Cross-Chain Smart Wallets with Privacy

Last year, Vitalik outlined ["The Three Transitions"](https://vitalik.eth.limo/general/2023/06/09/three_transitions.html) ahead for the Ethereum stack: moving to L2s, smart wallets, and private transactions. The Base team has built [Keyspace](https://docs.key.space/), a cross-chain keystore that helps all wallets makes these transitions. Come learn about how Keyspace works and how Keyspace helps smart wallets sync signers and send private transactions in a multichain world.

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.

Defragmenting Ethereum - Interoperability and the Superchain

With the proliferation of L2s and Dencun (4844), Ethereum has scaled. However, we have a new challenge -- fragmentation. Now we're introducing various interoperability standards across Ethereum and Superchain ecosystem from intents to low latency cross chain bridging primitives. What are these standards and what will enable? How can we create scalable and composable blockspace which enables application developers to onboard the rest of the internet?
