Abstract
The data economy generates trillions of dollars in value annually, yet individual data creators capture almost none of it. This talk examines how Decentralized Physical Infrastructure Networks (DePIN) and blockchain technology enable new models where individuals retain ownership and control of their data while participating in value creation. Drawing from practical experience building data economy protocols, I discuss the technical architecture, token economics, and governance mechanisms that make decentralized data markets viable. Topics include privacy-preserving data sharing, fair compensation mechanisms, federated learning for collaborative AI, and real-world case studies of successful DePIN deployments. The presentation balances theoretical foundations with practical implementation lessons from deploying these systems in production.
