In this fireside chat, Kartik Talwar interviews Jordi Baylina from the Gnosis team about the Ethereum Economic Zone (EEZ), a new protocol for synchronous cross-chain communication between Ethereum rollups. Jordi explains that EEZ enables smart contracts on different chains to call each other as if they were on the same chain — not just token transfers but any arbitrary contract call including voting, NFT operations, and more. This is made possible by breakthroughs in real-time ZK proving, where a full Ethereum block can now be proved with just 12 GPUs, down from 128 six months prior. Jordi walks through the technical architecture: when a cross-chain call happens, an execution table is stored on L1, zero-knowledge proved, and resolved within Ethereum's 12-second block time. Transactions between L2s are effectively free, limited only by GPU hardware. EEZ is permissionless — anyone can create a rollup, even non-EVM chains, as long as they support the call interface. Built by a nonprofit association with no token and no monetization, the project currently has a working internal DevNet with plans to open it publicly soon. Jordi flags block builder centralization as his primary concern, noting that validators must choose responsibly to preserve Ethereum's decentralization values. 00:00 Introduction 00:10 Welcome and What Is the Ethereum Economic Zone 01:12 Synchronous Cross-Chain Calls: The Core Idea 02:04 What Changed: Real-Time ZK Proving Breakthroughs 03:16 From 128 GPUs to 12: Engineering Progress 04:39 Two Years of Latency Reduction Work 06:14 How EEZ Differs from Bridges and Other Solutions 07:14 Nonprofit Structure: No Token, No Monetization 08:20 Connecting L1 to L2 and L2 to L2 09:25 Any Call Data Works: Not Just Token Transfers 09:59 Permissionless Rollup Creation and Non-EVM Support 11:45 How Real-Time Proving Works in Practice 14:39 Scaling: One Proof for All Instructions 15:37 Free Transactions Between L2s 16:38 Does EEZ Help or Fragment Ethereum 18:06 Concerns: Block Builder Centralization 19:35 Validator Responsibility and Decentralization 21:02 Project Status: DevNet Live, Public Access Soon 22:16 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *Pragma Cannes 2026* Pragma Cannes 2026 was held on April 2nd at the JW Marriott Hotel in Cannes, France and was an in-person summit for builders and leaders in the web3 ecosystem.
