## Description

In this powerhouse panel at Pragma Paris 2023, Polygon co-founders Sandeep Nailwal, Jordi Baylina, and Mihailo Bjelic dive deep into the technical evolution, vision, and future of Polygon and its alignment with Ethereum.

Explore how Polygon is scaling Ethereum through zkEVM, Polygon 2.0, and a unified multi-chain future built on ZK proofs. Jordi recounts the origin story of zero knowledge in Ethereum scaling, Mihailo outlines the architecture of Polygon 2.0, and Sandeep shares insights on bringing Web3 to a billion users. Learn about the POL token, interoperability layers, recursive ZK proofs, and how Polygon is building a trustless, Ethereum-secured value layer for the internet.

Whether you're a developer, founder, or protocol builder, this session is packed with cutting-edge insights on the tech, strategy, and culture powering one of Ethereum’s most important scaling ecosystems.

🇫🇷 *Pragma Paris*
Pragma Paris took place at the Pavillion Vendome in Paris on July 20, 2023, and was an in-person summit for builders and leaders in the web3 ecosystem. Watch the full Pragma Paris 2023 playlist here: https://youtube.com/playlist?list=PLXzKMXK2aHh42f0yI-hyeOCbNZpvV2fIT&si=Ez6ych6OAdn_sq1D

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