## Description

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.
