MyPDx

MyPDx is a blockchain-based personal health wallet developed through a collaboration between Molecular You, University of British Columbia, StonePaper, and Canada's Digital Technology Supercluster. The platform leverages Hyperledger Indy to implement a self-sovereign identity solution that gives individuals control over their healthcare data while enabling secure sharing with researchers and healthcare providers.

The technical architecture employs a permissioned blockchain network using Practical Byzantine Fault Tolerant consensus among nodes. Key features include:

• Verifiable Credentials for authenticating health data claims
• Privacy-enhancing technologies like selective disclosure and zero-knowledge proofs
• Decentralized Identifiers (DIDs) for peer-to-peer connections
• Role-based access control for patients, researchers, and healthcare providers
• De-identified data sharing capabilities for research purposes

The project received $1.5M in funding, including $0.6M from the Digital Technology Supercluster, and has conducted pilot testing with several partners including a major pharmaceutical company. Notable collaborators include representatives from the Government of British Columbia, Roche Canada, IBM, DNAstack, Microbiome Insights and Microsoft. While initially developed as a research project, MyPDx is transitioning toward commercialization with a focus on improving user experience around the verification processes while maintaining strong privacy guarantees.
