Agarwood Traceability Blockchain Platform – Technical Specification
1. Objective
The Harvesting & Grading Module formalizes the economic realization event in the agarwood lifecycle.
It ensures:
- Verified harvest eligibility
- Transparent weight and yield recording
- Standardized grading documentation
- Tamper-proof valuation records
- Buyer-verifiable authenticity
This is the most critical valuation checkpoint for investors and exporters.
2. Harvest Eligibility Validation
Before harvest is permitted, the system verifies:
- Minimum post-inoculation maturation period
- Growth Monitoring compliance
- Health status above threshold
- No active compliance flags
- Plantation geo-verification
If validated, smart contract status updates to: “Harvest Approved”
3. Data Fields Captured at Harvest
A. Tree / Block Identification
| Category | Data Captured |
|---|---|
| Plantation ID | Linked to registered plantation |
| Tree or Block ID | Unique blockchain reference |
| Inoculation Event ID | Linked to induction record |
| Harvest Date | Timestamp |
| Operator ID | Digital signature |
| Supervisor ID | Co-signature |
B. Physical Yield Metrics
| Parameter | Data Captured |
|---|---|
| Total Wood Weight | kg |
| Resinous Wood Weight | kg |
| Moisture Content | % |
| Resin Density | Lab-tested |
| Wood-to-Resin Ratio | Calculated |
| Grade Classification | A / B / C / Oil-grade |
| Photo Evidence | Hashed reference |
4. Grading Framework
The grading algorithm considers:
- Resin saturation level
- Color depth
- Aroma intensity
- Density
- Resin distribution pattern
Grading can be:
- Manual expert input (digitally signed)
- AI-assisted image analysis
- Lab-verified density scoring
Final grade is locked via smart contract.
5. Blockchain Workflow
Step 1: Harvest Declaration
Field operator logs harvest via mobile app.
Step 2: Smart Contract Execution
Harvest & Grading Smart Contract:
- Validates tree eligibility
- Records weight metrics
- Anchors grading data
- Hashes lab certificates
- Generates valuation snapshot
Step 3: Batch Consolidation
Individual trees grouped into:
- Harvest Batch ID
- Export Batch ID (if applicable)
Each batch receives a unique QR-linked blockchain record.
6. On-Chain vs Off-Chain Data
On-Chain:
- Harvest Batch ID
- Linked Inoculation Event
- Grade
- Weight
- Timestamp
- Operator & Supervisor signatures
- GPS hash
Off-Chain:
- Lab analysis reports
- HD photos
- Video grading evidence
- Moisture test sheets
All off-chain documents hashed and anchored immutably.
7. Fraud Mitigation Controls
- No harvest allowed without inoculation record
- No grading allowed without harvest record
- Multi-signature validation
- Geo-verified harvesting
- Duplicate batch detection
- AI anomaly detection (e.g., unrealistic resin ratios)
This protects against artificial grade inflation.
8. Financial & Valuation Layer
The module can integrate:
- Market price feeds per grade
- Real-time valuation per batch
- Revenue forecast modeling
- Export price benchmarking
Investors can see:
- Verified asset value per hectare
- Realized yield vs predicted yield
- ROI per inoculation cycle
9. Buyer-Facing Authentication
Upon grading:
- QR code generated for batch
- Buyer scans QR
- System displays:
- Plantation origin
- Inoculation date
- Growth history
- Harvest date
- Grade certification
This increases international trust, especially in premium GCC markets.
10. Strategic Impact
This module transforms agarwood from a trust-based commodity into a data-verified asset class.
For the market:
- Reduces disputes
- Strengthens export credibility
- Supports premium pricing
For investors:
- Locks valuation event immutably
- Reduces fraud risk
- Enables securitization potential
