ERC-3668 on Linea: built-in, trust-minimized L2 to L1 data retrieval

ERC-3668 (aka. CCIP-read) enable L1 contracts to access Linea state. No special library need to be integrated, everything is built into the protocol and secured by Linea's zero-knowledge proofs. During this presentation, we will go into the details of how this works, the benefits and use cases you can start building today.

Next Generation Based Rollups: A Practical Approach to Unifying Ethereum

I plan to speak on the concept of based sequencing (based rollups). I want to not only introduce the concept but also explain recent developments (what I like to call next generation based rollups). This includes based preconfirmations, fast->realtime proving, customizable composability, practical synchronous composability, among others. I will introduce I also plan to provide a brief summary to my Bankless Summit talk on ETH value accrual in the presence of based rollups.

The Future of Layer 2: Research, Development, and Next-Gen Technologies

Discussion around L2 blockchain research and development. What are the major challenges for L2s to advance, and what solutions are being explored? What will the L2 space look like next year and beyond? The talk will be illustrated with examples from Arbitrum’s research and development.

ZK in Rollups: Full Validity Proving on the OP Stack

Historically, zkEVM rollups have been difficult to build, requiring deep cryptography expertise that makes customization and maintainability complicated and time-consuming. With advancements in zk, zkVMs make it easy for any developer to write ZK applications with Rust. With a zkVM, we've created seamless way to upgrade ANY existing OP Stack chain to use ZKPs in just 1 hour. These rollups get fast finality, cost-effective (<0.1 cent / tx), and full EVM equivalence.

Are L2s extractive to Ethereum?

An in depth study of on chain metrics, fee markets, contracts, and wallets to answer if L2s are extractive to Ethereum

Ensuring Data Availability in L2s

The talk explores the risks associated with data availability (DA) providers in L2s, highlighting the necessary security guarantees of DA layers. It covers economic security considerations, security properties of DA attestations, and fraud detection mechanisms against data withholding attacks. The goal is to guide L2 users in understanding the different risk profiles of DA providers and assist developers and researchers in enhancing the security and functionality of L2 solutions.

L2 Specific MEV Mitigation Strategies

MEV mitigation and prevention has primarily been researched in the base L1 Ethereum layer. This talk explores L2 specific strategies, including the future in the event of decentralized sequencing. We explore emerging EIP proposals and drafts (EIP-7640), the use of intents in L2s and other new constructions.

Scaling autonomous worlds - building the foundations… and sewers for millions of inhabitants

One tends to think of Ethereum scaling in financial terms—how many transactions per second? What’s the TVL? How much liquidity? But in a possible future where Ethereum applications extend beyond finance, into areas like autonomous worlds, games, and social, what does scaling look like and what challenges await? Join us as we explore challenges, solutions, and open questions in this space—how do we bring latency down despite seconds-long block time? Could we shard an app across multiple chains?

Ecosystem Development Best Practices, and why we need to start with builders first

Given the myriad of chains out there, it is increasingly crucial for L2s to solidify their ecosystem building playbook and constantly refine it to win over (and more importantly, retain) users and builders. As an ecosystem builder in SEA (Thailand) who has worked with over 10 ecosystems including other L1s, on local, regional and global initiatives, I am excited to share the ins and outs of ecosystem building from a neutral perspective.

The Future of Light Clients

Ethereum has achieved a remarkable feat: production-ready light clients. There are now at least seven light client projects active on Ethereum today. However, light clients have kept up with Ethereum’s future, Layer 2s. Implementations for layer 2s have been mostly overlooked. This is due to both the low prioritization of work on light clients and significant technical challenges. In this talk, we will discuss the path to layer 2 light clients and our work to bring them to production in Helios.
