HIPAA-Compliant Radiology Collaboration Platform with Blockchain Rewards
End-to-end design and development of a cross-platform mobile application connecting U.S. board-certified radiologists for secure, anonymized case collaboration — featuring one-to-one and group encrypted messaging, automated NPI credential verification, and a Polygon-based utility token (Radcoin) that rewards quality peer contributions with a fixed 20M token supply and community-governed distribution. Live on iOS, Android, and macOS.
Client: Radish Group LLC
The Challenge
Radiology faces a critical isolation crisis: 70% of radiologists report burnout (RSNA surveys), driven by solo reads, limited peer access, and inefficient case discussion workflows. Existing tools — grand rounds, email threads, static forums — are slow, formal, and provide no incentive for meaningful participation. The client needed a mobile-first platform that could instantly verify professional credentials via the CMS NPI Registry, fully anonymize patient data at upload, facilitate real-time encrypted one-to-one and group collaboration across subspecialties, and incentivize high-quality contributions through a transparent blockchain rewards system — all while maintaining strict HIPAA, CCPA, CIPA, CMIA, and NY SHIELD Act compliance.
The Solution
We architected a React Native cross-platform application targeting iOS, Android, and macOS (Apple Silicon), backed by Supabase for real-time database, authentication, file storage, and row-level security (RLS). The verification module integrates directly with the CMS NPI Registry for automated credential validation of attending radiologists, plus program confirmation for residents and fellows. We implemented end-to-end encrypted messaging supporting both one-on-one direct messages and WhatsApp-style group chats for residency cohorts, fellowship groups, teleradiology teams, and private study partners — all maintaining full user anonymity. The Radcoin (RAD) rewards system was built on a custom ERC-20-inspired smart contract deployed to the Polygon network for low gas fees and high throughput, with dynamic conversion rates linking quality ratings (1-10 scale) to token distribution. A comprehensive dashboard tracks Radcoin balance, comment ratings, badges, and professional milestones. The UI supports four themes (Light, Dark, Blue, Green) optimized for clinical reading environments, smart notifications keep users informed without overwhelming workflow, and all uploaded cases auto-purge after discussion with full audit logging throughout.
Key Features
Anonymized Case Sharing
Upload fully de-identified radiology images with teaching points and key findings. Post anonymously or with a verified profile to public or private group feeds. All cases auto-purge after discussion with no patient identifiers stored.
Automated NPI Verification
Real-time integration with the CMS NPI Registry validates professional credentials for attending radiologists. Residents and fellows are verified through program confirmation, ensuring a spam-free, trusted professional network.
One-to-One & Group Encrypted Chat
End-to-end encrypted messaging supporting both private one-on-one consultations and WhatsApp-inspired group chats for residency cohorts, fellowship groups, teleradiology teams, and study partners — all while maintaining full user anonymity.
Quality-Based Radcoin Rewards
Custom ERC-20-inspired smart contract on Polygon with a fixed 20M RAD supply and zero inflation. Tokens are earned only when the original case poster rates a comment highly (1-10 scale), ensuring rewards align with genuine clinical value. Dynamic conversion rates sustain the 20-year distribution model.
Multi-Theme Clinical UI
Four professionally designed themes — Light, Dark, Blue, and Green — each optimized for different radiology reading environments. Reduces eye strain during long shifts with carefully calibrated contrast and color schemes.
Professional Recognition Dashboard
Comprehensive analytics tracking Radcoin balance, comment ratings, activity history, badges, and career milestones. Builds verifiable professional reputation within the verified radiology community. CME integration planned for future releases.
Privacy-First Architecture
Auto-generated avatars protect user identity while maintaining professional connections. All cases are fully anonymized with in-app safeguards and visual prompts preventing unintended PHI uploads. Secure one-on-one and group messaging with end-to-end encryption.
Enterprise-Grade Compliance
Built on Supabase infrastructure with database-level security policies, row-level security (RLS), TLS 1.3 encrypted connections, and comprehensive audit logging. Compliant with HIPAA, CCPA/CPRA, CIPA, CMIA, and NY SHIELD Act standards.

Architecture
The platform is built on a three-tier architecture spanning mobile, backend, and blockchain layers. The React Native mobile layer delivers a native-feeling experience across iOS, Android, and macOS with four theme variants and real-time collaboration features. The Supabase backend provides PostgreSQL with row-level security (RLS), real-time subscriptions for chat and notifications, secure file storage for anonymized radiology images, and built-in authentication integrated with the custom NPI verification pipeline. The blockchain layer consists of a custom ERC-20-inspired smart contract deployed on Polygon for low-gas, high-throughput RAD token transactions, with an in-app non-custodial wallet and dynamic conversion rates that adjust based on community growth. End-to-end encryption protects all messaging channels, TLS 1.3 secures data in transit, and database-level RLS policies ensure data isolation between users — all backed by comprehensive audit logging for regulatory compliance.
Project Timeline
The project launched in phases starting Q4 2025 with the MVP including NPI verification, case posting, comment-based RAD earning, and one-to-one messaging. The Growth phase (Q1-Q2 2026) added group chats, four UI themes, and expanded the verified user base. The Expansion phase (Q3-Q4 2026) introduces sponsored cases and group chat v2. The Maturity roadmap (2027+) targets CME pathway integration and potential RAD transferability subject to governance and regulatory approval.
