Onboarding: Phone number, OTP, name, village Device-bound keypair (ed25519) Profile Creation: Land area, address, photo, payment mode, KYC/Aadhaar Collection Event: Photos/videos (geo-tagged), species, plant part, quantity, notes Auto GPS, timestamp, device ID, EXIF Event signed with private key, batch ID UUID Storage: Local DB (offline-first) IoT Inputs: Weighing scale, moisture/soil sensors, weather API

Sync Mechanism: Offline events queued, async sync SMS fallback if no internet Backend Validation: Verify signature via on-chain registry File hash stored on CouchDB Hash + metadata on blockchain Smart Contract Checks: Geo-fencing, seasonal rules, anomaly detection Valid → blockchain record, QR generated Farmer notified via SMS + dashboard

Farmer dashboard → Approved submission Farmer QR scan to transfer Processor scans Batch ID (herb, farmer ID, date) Inputs: received weight, seal ID, photo Multi-sig custody transfer event Hash recorded on-chain Payment released via 3rd party app Transaction details saved

Login (Processor role) Dashboard: view received batches Step Entry Form: - Select batch - Step type (drying, grinding, etc.) - Start/end date-time - Temp/humidity range - Post-processing weight - Storage conditions - Photos before/after - Notes, operator ID, digital signature Validation rules: - Flag anomalies (weight, sequence, photos) Compliance fields: - Equipment used - Cleaning log confirmation - Batch segregation checkbox System actions: - Record event on blockchain - Update batch timeline - Generate QR for lab transfer IoT integration: - Temp & humidity sensors auto-log

Login (LabTester role) Dashboard: scan QR, fetch batch metadata Quality Test Entry Form: - Sample receipt (weight, date/time, condition) - Tests: physicochemical, safety, authentication - Tester inputs: test name, method, equipment, results, notes, photos System actions: - Validate thresholds - AI generates report & quality score - Store hash on blockchain - Auto-generate E-certificate - Store report & certificate - Create QualityTest event on blockchain IoT integration: - Instruments auto-upload results

6. Manufacturing Workflow

Login (Manufacturer) View lab-verified batches Select batches to combine Enter product details Upload packaging photos Smart contract validations: - Valid QualityTest events - No freeze or anomalies Mint product batch token Generate & print QR Event: ProductBatchMinted

Consumer scans QR on retail packet View provenance map & photos Full timeline: collection → manufacturing Lab certificate & quality report Farmer/community profile & badges Consumer feedback form Triggers regulator alert

Login (Regulators) Monitor network health Query batch timelines & anomalies Recall/freeze suspicious batches Export compliance & sustainability reports Analytics: harvest volumes, demand forecasting, sustainability alerts
