Building Consumer Apps For A User Owned Privacy First Web - Yaniv Tal

Thu, Oct 2, 2025, 12:00 AM

Yaniv Tal, founder of The Graph, discusses building consumer apps for a user-owned, privacy-first Web3. He highlights the dominance of Web2 apps, emphasizing the need for user freedom and data ownership in Web3. Yaniv introduces knowledge graphs as a core primitive for interoperable, composable data across applications, crucial for both public and private data. He unveils GRC20, a new standard for interoperable knowledge graphs, and Hyperraph, a local-first framework enabling real-time, privacy-preserving, and interoperable Web3 consumer apps. Hyperraph leverages CRDTs and end-to-end encryption for private data, and GRC20/IPFS for public data, allowing developers to build open, interconnected apps on Ethereum. Yaniv demonstrates building a fashion app using these tools, showcasing rapid development and collaboration. He encourages developers to join the ETHGlobal hackathon, aiming to expand Ethereum’s ecosystem beyond DeFi to diverse, user-empowering applications. 00:00 Introduction 00:33 Yaniv Tal’s Background & Motivation 01:19 Web2 vs Web3 Consumer Apps 02:13 The Value of User Freedom & Data Ownership 03:14 Introduction to Knowledge Graphs 04:13 Open, Interconnected Knowledge Graphs 05:12 Privacy, Permissions, and Interoperability 06:05 GRC20: Standard for Knowledge Graphs 06:43 The Role of Frameworks in App Growth 07:47 Announcing Hyperraph: Local-First Web3 Framework 08:39 Privacy, Real-Time Sync, and Data Interoperability 09:03 Building Apps with Hyperraph (Demo) 11:00 Organizing Public Knowledge & Data Sets 11:34 Private Data Spaces & Collaboration 12:47 Expanding App Possibilities on Ethereum 13:15 Hyperraph Team & Hackathon Invitation 13:59 Call to Action & Closing Remarks _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *Pragma Cannes* Pragma Cannes 2025 was held on July 3rd at the Carlton Cannes in Cannes, France and was an in-person summit for builders and leaders in the web3 ecosystem.
