SOS offers a simple yet powerful solution for storing and accessing vital emergency medical information via the Stellar blockchain. The system focuses on critical data needed in emergencies:
- Blood Type
- Critical Allergies
- Current Medications
- Medical Conditions
- Emergency Contacts
Unlike traditional medical record systems that require complex integrations and permissions, SOS is designed for simplicity and universal accessibility in emergency situations.
SOS leverages Stellar's Account Data Entries as the primary storage mechanism for medical information, offering several key advantages:
- Simplicity: Minimal blockchain operations required.
- Direct Storage: Data is written directly to the blockchain.
- Universal Access: Authorized providers can access data via a web interface.
- Cost-Effective: Minimal transaction costs with maximum security.
-
Storage Layer:
- Each user has a dedicated Stellar account to store their emergency medical data.
- Data is stored using standardized keys for universal recognition (e.g.,
blood_type,allergies).
-
Access Control:
- QR codes linked to the user's Stellar account enable emergency access.
-
User Interface:
- A web application for users to create and retrieve profiles.
- Simple registration process requiring minimal personal information.
- Easy input of critical medical data through user-friendly forms.
- Generation of personalized QR codes for wallets, phone cases, or wearables.
- Instant access to critical patient information by scanning QR codes.
- Clear presentation of time-sensitive medical data (e.g., allergies, conditions).
- One-click access to emergency contacts.
- No specialized equipment required—just a web browser.
SOS addresses several critical healthcare challenges:
- Emergency Preparedness: Provides instant access to life-saving information during emergencies.
- Global Accessibility: Works across borders, languages, and healthcare systems.
- Digital Inclusion: Accessible to anyone with a smartphone.
- Traveler Security: Peace of mind for international travelers and digital nomads.
- Data Security: Protects sensitive medical information through blockchain technology.
Stellar is the ideal infrastructure for SOS due to its:
- Low Transaction Costs: Affordable even at scale (~$0.00001 per update).
- Fast Transaction Finality: Critical for emergency applications.
- Account Data Entries: Perfect for storing structured data like medical records.
- Global Accessibility: Aligns with Stellar's mission of financial inclusion.
- Simple SDK: Enables rapid development of the MVP.
| Feature | SOS Implementation | Traditional Approach |
|---|---|---|
| Data Access | Global <1s retrieval | Regional EHR lookup |
| Cost | $0.00001 per update | $5–20 EHR update fees |
| Security | Immutable audit trail | Centralized DB risks |
- Set up development environment with Stellar testnet.
- Design data schema for emergency medical information.
- Implement core Stellar account operations.
- Build user registration and profile generation interfaces.
- Develop emergency access portal for healthcare providers.
- Implement QR code generation and post scanning functionality.
- Prepare documentation and demonstration materials.
- Landing Page: A well designed page to explain SOS benefits.
- Medical Data Input: Forms for entering essential emergency information.
- QR Code Generation: Unique codes linked to users' Stellar accounts.
- Emergency Access Portal: Web interface for healthcare providers.
Post-MVP development will focus on expanding SOS capabilities:
- Expanded Medical Record Integration: Connect with existing EHR systems.
- Biometric Authentication: Enhance security for sensitive information.
- Localization: Support additional languages and regional standards.
- Provider Verification: Blockchain-based credentials for healthcare providers.
- Wearable Integration: Collaborate with medical wearables manufacturers.
SOS's sustainability model can be achieved through:
- Healthcare Organization Sponsorships: Hospitals and clinics sponsor user accounts.
- Insurance Provider Partnerships: Reduced premiums for members using SOS.
- Government Healthcare Initiatives: Public health programs funding access.
- Non-Profit Organization Support: NGOs supporting vulnerable populations.
- Travel Insurance Integration: Bundled offerings for travelers and digital nomads.
- Stellar Network community funds.
Safety On Stellar (SOS) offers an elegant solution to a universal problem—access to critical medical information during emergencies. By leveraging Stellar's blockchain capabilities, SOS ensures secure, global accessibility to life-saving data when seconds count.
This project aligns perfectly with the Better Access track of the Stellar Hackathon by democratizing access to critical medical information, showcasing how blockchain technology can address real-world healthcare challenges effectively.
