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.
Crypto Twitter is Wrong: This is How Rollups *Really* Work
It's 2024, L2s are a critical part of the Ethereum scaling roadmap, and everyone *still* gets Rollups completely wrong. If you think that Optimistic Rollups and ZK Rollups are real things, that Rollups need sequencers to create blocks, or that Rollups need proofs to be secure, you've been completely and utterly bamboozled by the Crypto Twitter intelligentsia. It's time we take back the truth - this is How Rollups *Really* Work.
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.
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.
Speedrun Rollups: A Beginner's Guide to L2s, ZK, and WTF People are Talking About on Panels
The L2 landscape has grown, both in terms of size, but also the development of the tech and the new problems that need to be solved. This talk aims to take you from zero to hero, equipping you with the history, development, and current state of L2s, so you can maximize your Devcon experience without having to carry around a dictionary to understand WTF people are talking about.
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.
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.
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.
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.
