Platform Services Implementation

🎬 Research Collaboration Network - Live Platform Demo

🏥 Medical Institution Service​

Core Functionality​

The Medical Institution Service manages hospital registration, doctor verification, and institutional coordination through blockchain integration.

Key Features​

Institution Registration​

async registerInstitution(institutionData: MedicalInstitution): Promise<{
  walletAddress: string;
  transactionHash: string;
  credentialHash: string;
  blockNumber?: number;
  timestamp: Date;
}>
  • Blockchain Registration: Direct integration with MedicalVerification contract
  • Credential Hashing: Secure hashing of institution credentials using keccak256
  • Real-time Verification: Immediate on-chain verification status
  • Gas Optimization: Efficient transaction handling with proper error management

Doctor Registration & Verification​

async registerDoctor(doctorData: DoctorRegistration): Promise<{
  walletAddress: string;
  transactionHash: string;
  stakeAmount: string;
  blockNumber?: number;
  timestamp: Date;
}>
  • Staking Mechanism: 0.0005 0G stake required for doctor registration
  • Institutional Backing: Verification through associated medical institutions
  • Blockchain Verification: Direct integration with MedicalCollaborationHub contract
  • Error Handling: Comprehensive error messages for insufficient funds, verification issues

Data Management​

Blockchain Cache System​

  • Performance Optimization: Local caching with blockchain as source of truth
  • Real-time Sync: Automatic synchronization with deployed contracts
  • Fallback Mechanisms: Direct blockchain queries when cache misses occur

Database Integration​

  • Supabase Integration: Structured storage for user profiles and medical metadata
  • HIPAA Compliance: Secure handling of medical professional information
  • Cross-Reference: Wallet addresses linked to institutional affiliations

🌐 Cross-Border Consultation Service​

Implementation Architecture​

class CrossBorderConsultationService {
  async createConsultation(
    patientCase: MedicalCase,
    specialists: SpecialistRequest[]
  ): Promise<ConsultationSession>;
}

Key Capabilities​

Smart Contract Deployment​

  • Dynamic Contract Creation: Consultation-specific smart contracts on 0G Chain
  • Multi-Specialist Coordination: Automated specialist matching and invitation
  • Payment Escrow: Secure payment handling through smart contracts
  • Dispute Resolution: Built-in arbitration mechanisms

Real-time Communication​

  • Encrypted Channels: Secure communication between international medical teams
  • Medical Data Sharing: HIPAA-compliant patient data transmission
  • Consent Management: Granular patient permissions for data access

🔐 Medical Authority Verification​

Global Authority Network​

interface MedicalAuthority {
  id: string;
  name: string;
  country: string;
  region: string;
  type: "licensing_board" | "medical_council" | "professional_association";
  credentials: string[];
  verificationEndpoint: string;
  isActive: boolean;
}

Implemented Authorities​

  • US Federation of State Medical Boards (FSMB)
  • UK General Medical Council (GMC)
  • European Medicines Agency (EMA)
  • Australian Health Practitioner Regulation Agency (AHPRA)
  • Canadian Medical Association (CMA)

Verification Process​

async verifyCredential(
  credentialHash: string,
  authorityId: string
): Promise<VerificationResult>
  • Credential Hash Verification: Secure verification without exposing sensitive data
  • Multi-Authority Cross-Check: Validation across multiple medical boards
  • Real-time Status Updates: Live credential status monitoring
  • Blockchain Integration: Immutable verification records on 0G Chain

💾 Data Storage Architecture​

0G Storage Integration​

// Client-side encryption before storage
const encryptedChunks = await encryptClientSide(medicalFiles, hospitalKey);

const medicalManifest = {
  caseId: generateMedicalCaseId(),
  contentHash: uploadResult.rootHash,
  encryptionMetadata: {
    algorithm: "AES-256-GCM",
    accessControlList: ["authorized_institutions"],
  },
};

Security Framework​

  • Client-Side Encryption: All medical data encrypted before transmission
  • Zero-Knowledge Architecture: Platform never accesses raw patient data
  • Granular Access Controls: Institution-level permissions with patient consent
  • GDPR Compliance: Automated compliance with international privacy regulations

Storage Configuration​

  • 0G Storage Indexer: https://indexer-storage-turbo.0g.ai
  • Redundancy: Multiple node replication for data availability
  • Performance: Sub-second medical data retrieval globally

🔗 Contract Test Service​

Real Contract Integration​

class ContractTestService {
  // Mainnet contract addresses
  RESEARCH_HUB_ADDRESS = "0x035F1565aeeB03DF80Dfe65aeBF0d03Bec5bf696";
  CLINICAL_TRIAL_HUB_ADDRESS = "0x55bA3CCf5Ac075D107e9F1843a5f3abea3C050a2";

  async testInstitutionRegistration(): Promise<TestResult>;
  async testDoctorRegistration(): Promise<TestResult>;
  async testMedicalCaseRegistration(): Promise<TestResult>;
}

Testing Capabilities​

  • End-to-End Testing: Complete workflow testing from registration to consultation
  • Gas Usage Analysis: Real transaction cost monitoring
  • Error Handling Validation: Comprehensive error scenario testing
  • Performance Metrics: Response time and throughput measurements

📱 Frontend Integration​

SvelteKit Platform​

// Wallet integration with Reown AppKit
import { walletManager } from "$lib/wallet";
import { medicalInstitutionService } from "$lib/services/medicalInstitutionService";

// Real-time blockchain interaction
const registrationResult = await medicalInstitutionService.registerDoctor(
  doctorData
);

Technology Stack​

  • Framework: SvelteKit with TypeScript
  • Styling: Tailwind CSS for responsive design
  • Web3 Integration: Ethers.js v6.13.1 with Reown AppKit
