Built for the Worst Moments. Engineered for the Best Outcomes.

Every feature in VitalChain was designed for the unique demands of emergency medicine.

Access Control

Role-Based Access Control

Not everyone needs to see everything. VitalChain's granular RBAC system ensures that each responder type, from EMT-Basic to Critical Care Paramedic, sees exactly the data appropriate for their role and certification level.

  • 14 distinct responder types including paramedic, firefighter, law enforcement, and coast guard
  • 4 access tiers: Low, Medium, High, and Emergency Override
  • Emergency override for life-threatening scenarios with full audit trail
  • NPI verification via CMS NPPES Registry for provider credentialing

EMT-Basic → LOW
Paramedic → MEDIUM
Critical Care → HIGH
Emergency → OVERRIDE

Connectivity

Offline-First Architecture

Emergencies don't wait for internet. VitalChain's offline-first architecture ensures that critical patient data is always available, regardless of network connectivity; a capability unique in the emergency medical records space.

  • AES-256 encrypted local cache on responder devices
  • Priority-based eviction ensures emergency-critical data is cached longest
  • Automatic sync reconciliation when connectivity is restored
  • Hash-based offline credential verification

No signal? No problem.
Critical data stays accessible.

Safety

Clinical Decision Support

VitalChain's integrated CDSS engine provides real-time safety alerts that help responders avoid potentially dangerous clinical decisions during the most critical moments.

  • Drug-allergy conflict detection with critical safety gates
  • Drug-drug interaction warnings
  • Chronic condition alerts and critical care notes
  • Real-time clinical charting with write-back to blockchain

Intelligent alerts.
Safer decisions.

Interoperability

EHR Integration via HL7 FHIR R4

VitalChain speaks the language of modern healthcare. Bidirectional synchronization with major EHR systems means hospital data flows seamlessly into the VitalChain network and back.

  • Bidirectional sync with Epic, Cerner, and MEDITECH
  • SMART on FHIR OAuth2 Backend Services authentication
  • Conflict detection and resolution for bidirectional data flow
  • HMAC-SHA256 signed webhook notifications for sync events

Standards-based integration.

Compliance

Security & Compliance

VitalChain is built on Hyperledger Fabric; a permissioned blockchain that provides an immutable, tamper-proof audit trail for every data access event. Every interaction is logged forever.

  • Hyperledger Fabric 2.5 permissioned blockchain
  • Multi-provider authentication: SSO, CAC/PIV, FIDO2, SAML, OAuth2
  • HIPAA-compliant audit trail with accessor ID, role, and timestamp
  • Real-time anomaly detection for suspicious access patterns

Immutable. Auditable. Compliant.
Every access, logged forever.
