Keynote: Unifying Ethereum Through Intents and ERC-7683

Duration: 00:25:43

Speaker: Hart Lambur

Type: Talk

Expertise: Intermediate

Event: Devcon

Date: Nov 2024

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.

“Unified Ethereum” vs “L2 Ecosystem Competition”: Can we have both?

This panel will dig into the delicate balance of Ethereum's rollup-centric future. We'll talk about the "frenemy" dynamic between competing L2 ecosystems, and how this can lead to a fragmented user experience. We'll strategize on ways to maintain diversity while making interoperability easy for users—including a discussion on the pros/cons of supporting standards like ERC-7683. Can we get the best of both worlds: the innovation and diversity of many L2s, with the UX of a unified Ethereum?

Why ERC 7683 is broken and how to fix it

While I appreciate the authors spending time on this problem statement and thinking about standardising flows, ERC 7683 is deeply flawed it still forces offchain agents to understand the order they are trying to fulfill and it doesnt give users any guarantees of execution or understanding of whats happening under the hood, I think its because its standardising things on the "intent" layer where instead we need to standardise more downstream so information like security can be better presented

RIP-7755: Empowering Cross-Chain Interactions

Cross-chain interactions are becoming essential as Ethereum Layer 2 solutions multiply. RIP-7755 changes the game by trustlessly bridging the gap between L2 chains, allowing new use cases that rely solely on Ethereum and its rollups. In this workshop, we’ll explore RIP-7755 by building a cross-chain NFT minting app, focusing on nested storage proof implementation details to eliminate trust assumptions.

Ethereum needs native L2 preview

Ethereum needs native L2

Right now, L2beat tracks 116 L2s. However, they represent a wide range of trust assumptions, which makes assets—or more abstractly, messages—from these L2s non-fungible and thus significantly hampers interoperability. We are advocating for Ethereum to deploy a large number of native L2s, developed and governed by Ethereum's open-source developers. These L2s would be highly interoperable with L1, fulfilling Ethereum's early promise to provide sharding using L2 technology.

L2 Interoperability via Collaborative SNARKs

Can contracts across rollups interact synchronously while maintaining horizontal scalability? The L2 interoperability problem can be viewed through the lens of collaborative SNARKs, where a coordinator splits a witness over N provers who collectively generate a proof, and the work each prover does should decrease linearly in N (horizonal scaling). This talk presents a solution for the special case of L2 interoperability and motivates new design constraints for SNARKs.

The Age Of AGGREGATION

Aggregation plays a critical role in enhancing the usability and scalability of blockchain technology. In this session, we will explore the fundamental concepts of aggregation, debunk common myths, and discuss the necessity of aggregated blockchain systems for achieving real-world usage. Current scalability boundaries limit blockchain's potential, but through aggregation, we can optimize performance and usability, making blockchain technology accessible to a broader audience

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.

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?
