## Description

Explore the future of Ethereum scaling in this must-watch panel from Pragma Denver 2024. ETHGlobal’s Kartik Talwar moderates a powerful conversation with leaders from Polygon Labs (Sandeep Nailwal), Celo (Rene Reinsberg), Matter Labs / zkSync (Alex Gluchowski), and Offchain Labs / Arbitrum (Steven Goldfeder). Topics include rollup architecture, ZK vs. optimistic proofs, chain aggregation vs. modularity, L2 vs. L3 infrastructure, and the race to build a seamless, trustless internet.

Learn how the major Ethereum ecosystems are converging on scalability, composability, and decentralization—and what the road to a unified onchain economy really looks like.

🇺🇸 *Pragma Denver*
Pragma Denver 2024 took place at The Arch in Denver on February 28, 2024, and was an in-person summit for builders and leaders in the web3 ecosystem. Pragma is a one-stage conference with founders-only on stage, bringing together a small group of curated attendees and speakers to discuss the future of web3 and reflect on the past. Watch the full Pragma Denver playlist here: https://youtube.com/playlist?list=PLXzKMXK2aHh4lJw0vruQ4prh8iMDUk89i&si=ayJ64Sgcqew1fdFk

ETHGlobal's Pragma series takes place in cities around the world, and is designed to be a different kind of event. Ever since we first introduced our new event series, Pragma, in Tokyo in the spring of 2023, we have been fostering a curated, global community of individuals who deeply care about web3.
