   ## Summary
   
   This PR implements the IPFS/Filecoin integration for encrypted storage as described in issue #12. It enables the platform to store large datasets off-chain while maintaining on-chain metadata and ensuring data availability.
   
   ## Changes Made
   
   ### Smart Contract Updates (Soroban)
   - ✅ **Store IPFS hash (CID)** in Soroban contract
   - ✅ **Ensure CID immutability** once analytics task starts
   - ✅ **Implement Data Availability** check before running queries
   - ✅ **Support versioning** of datasets for historical analytics
   - ✅ **Handle decryption keys** via on-chain/off-chain hybrid model
   
   ### Backend Service Integration
   - ✅ **Automate pinning** of datasets via Pinata service
   - ✅ **IPFS service** with upload, pin, and retrieval capabilities
   - ✅ **Filecoin deal monitoring** for long-term storage
   - ✅ **Encryption key management** with secure hashing
   
   ### API Endpoints
   - `POST /api/v1/ipfs/upload` - Upload and pin files
   - `GET /api/v1/ipfs/availability/:cid` - Check data availability
   - `POST /api/v1/ipfs/pin/:cid` - Pin existing CIDs
   - `GET /api/v1/ipfs/deals/:cid` - Get Filecoin deals
   - `POST /api/v1/ipfs/batch-pin` - Batch pinning operations
   - `POST /api/v1/ipfs/verify-key` - Verify decryption keys
   
   ### Documentation
   - ✅ **Comprehensive documentation** for third-party auditors
   - ✅ **API reference** with examples
   - ✅ **Security guidelines** and best practices
   - ✅ **Troubleshooting guide** and monitoring setup
   
   ## Key Features
   
   ### 🔐 Security
   - End-to-end encryption before IPFS upload
   - Hybrid key management (on-chain hashes, off-chain keys)
   - Content addressing ensures data integrity
   - Access control and audit trails
   
   ### 📊 Data Availability
   - Automatic Pinata pinning for persistence
   - Filecoin deal monitoring for long-term storage
   - Regular availability checks and alerts
   - Automated re-pinning of unavailable content
   
   ### 🔄 Version Control
   - Dataset versioning for historical analytics
   - Immutable CIDs once analysis starts
   - Traceable dataset lineage
   - Rollback capabilities
   
   ### 📈 Monitoring
   - Real-time availability status
   - Pin status monitoring
   - Filecoin deal tracking
   - Performance metrics and alerting
   
   ## Configuration
   
   Add these environment variables to your `.env` file:
   
   ```env
   # IPFS Configuration
   IPFS_GATEWAY_URL=http://localhost:5001
   IPFS_PUBLIC_GATEWAY=https://gateway.pinata.cloud
   
   # Pinata Configuration
   PINATA_API_KEY=your_pinata_api_key
   PINATA_SECRET_KEY=your_pinata_secret_key
   
   # Filecoin Configuration
   FILECOIN_ENABLED=true
   FILECOIN_MIN_DEAL_DURATION=525600

   Testing

   The implementation includes:

   • Comprehensive error handling
   • Input validation and sanitization
   • Type safety with TypeScript
   • Security best practices

   Impact

   This implementation enables:

   • Scalable storage for large datasets
   • Reduced on-chain costs by storing data off-chain
   • Enhanced privacy through encryption
   • Improved reliability with pinning and Filecoin deals
   • Audit compliance with comprehensive logging

   Breaking Changes

   • The request_analysis function now requires an IPFS CID parameter
   • New dependencies added to backend package.json
   • Additional environment variables required

   Documentation

   See docs/ipfs-filecoin-integration.md for detailed documentation.
