6.3 How buyers verify on-chain data

Buyer Verification of On-Chain Data in Agarwood Supply Chains

From Plantation to Purchase – Transparency You Can Trust

1. What On-Chain Data Means

  • “On-chain” refers to information stored on a blockchain, which is immutable, time-stamped, and tamper-proof.
  • In agarwood supply chains, this includes:
    • Tree UTIDs and seed source
    • Inoculation records (BarIno System)
    • Harvest events and batch creation
    • Chip grading, resin classification, and oil distillation
    • Packaging, labeling, and export documentation

Key Feature: Once recorded, on-chain data cannot be altered or deleted, ensuring buyers access verified, trustworthy information.

2. Buyer Verification Methods

MethodHow It WorksBenefits
QR Code ScanBuyer scans QR code on package or batch label → instantly retrieves linked on-chain recordQuick, accessible verification of tree origin, batch, and quality
Blockchain Ledger AccessBuyer logs into blockchain platform → searches by Batch ID, UTID, or shipment IDFull audit trail: planting → inoculation → harvest → processing → packaging
Digital Certificate / Proof-of-OriginSystem generates a PDF or digital certificate signed by blockchainEasy to share, official, and tamper-proof
Mobile App VerificationBuyer uses a traceability app → scans batch/tree QR or enters ID → sees history, grades, and legal complianceIntuitive, mobile-friendly, supports multiple batches

3. What Buyers Can Verify On-Chain

  • Origin & Seed Source: Confirms species, nursery, and plantation
  • Tree & Batch Integrity: UTIDs linked to harvest events and batch IDs
  • Inoculation & Resin Development: Type, date, operator, and method
  • Quality & Grading: Chip grade, resin classification, oil batch parameters
  • Compliance & Legal Status: CITES, DENR, CNC, ECC permits, and export-ready documentation
  • Chain of Custody: Every transfer, storage, and processing event, with timestamps

4. Sample Buyer Verification Workflow

  1. Buyer scans QR code on batch
  2. Mobile app or platform opens on-chain record
  3. Buyer sees:
    • Tree IDs, batch ID, and GPS plot location
    • Inoculation history (BarIno System)
    • Chip grading, resin classification, oil distillation
    • Packaging & legal compliance data
  4. Buyer confirms all data matches quality, quantity, and origin
  5. Buyer approves purchase, confident in traceability and premium authenticity

Visual Concept:

Package QR → Scan → On-chain Record → Tree/Bath Verification → Inoculation → Harvest → Grade → Packaging → Compliance → Buyer Confidence

5. Farmer Tips for Buyer Verification

  • Ensure all tree, batch, and processing records are on-chain before sale
  • Print or attach QR codes clearly on packages
  • Use mobile-friendly apps for buyer access
  • Consolidate batch certificates and legal documents digitally linked to blockchain
  • Maintain operator verification logs for audit purposes

6. Benefits of On-Chain Verification for Buyers

  • Confidence in product authenticity and traceable origin
  • Proof of compliance with CITES and local regulations
  • Premium pricing justified by verifiable quality and provenance
  • Fraud prevention: prevents substitution or mislabeling
  • Audit-ready: every step can be independently verified

Key Message

“Buyers can verify every tree, batch, and harvest on-chain in real time. QR codes, blockchain records, and digital certificates guarantee traceability, authenticity, and premium value from seedling to final product.”
