7.4 Demonstration of digital ledger transactions

Here’s a detailed guide for demonstrating digital ledger transactions in an agarwood blockchain traceability system:


1. Purpose of Digital Ledger Transactions

digital ledger (blockchain) records every action in the agarwood supply chain immutably and transparently, enabling:

  • Traceability from plantation to consumer
  • Verification of authenticity and legality
  • Automation of payments and compliance via smart contracts
  • Auditable ESG and sustainability reporting

2. Key Types of Ledger Transactions

Transaction TypeExample in Agarwood Supply Chain
Batch CreationCreating a digital twin for a harvested batch (batch ID, tree info, harvest date)
Data RecordingLogging inoculation, extraction, resin grade, lab test results
Certification UploadUploading CITES permits, e-certifications, ESG audit reports
NFT MintingCreating NFT-backed certificate for authenticity and provenance
Ownership TransferTransferring NFT or batch ownership from farmer → exporter → buyer
Payment ExecutionSmart contract triggers payment to farmer/cooperative upon verified compliance
Shipment UpdateUpdating location and storage conditions during transit
Consumer VerificationQR/NFC scan triggers read-only ledger query to verify authenticity

3. Demonstration Workflow Example

Step 1: Batch Creation

Transaction ID: 0001
Type: Batch Creation
Details: Batch #27, Tree ID A123, Plantation GPS 10.123,15.456, Species Aquilaria malaccensis
Timestamp: 2025-11-14 10:05
Recorded by: Plantation IoT Gateway

Step 2: Data Logging

Transaction ID: 0002
Type: Data Recording
Details: Inoculation with Fusarium oxysporum, 15-Aug-2025, Expected resin formation
Timestamp: 2025-11-14 10:10
Recorded by: Farm Manager

Step 3: Certification Upload

Transaction ID: 0003
Type: Permit Upload
Details: CITES Permit #PH-2025-047, Verified Grade A
Timestamp: 2025-11-14 10:15
Recorded by: Regulatory Authority Node

Step 4: NFT Minting

Transaction ID: 0004
Type: NFT Minting
Details: NFT #OUD-00027, Links to Batch #27 digital twin, Owner: Farmer Cooperative Wallet
Timestamp: 2025-11-14 10:20
Recorded by: Blockchain Smart Contract

Step 5: Ownership Transfer

Transaction ID: 0005
Type: Ownership Transfer
Details: NFT #OUD-00027 transferred from Farmer Cooperative → Exporter ABC
Timestamp: 2025-11-14 10:25
Recorded by: Blockchain Smart Contract

Step 6: Payment Execution

Transaction ID: 0006
Type: Payment Execution
Details: 50% of batch sale price released to Farmer Cooperative
Trigger: NFT ownership verification
Timestamp: 2025-11-14 10:30
Recorded by: Smart Contract

4. Features of Ledger Transactions

  1. Immutable: Once recorded, transactions cannot be altered
  2. Traceable: Every batch has a chronological record of all actions
  3. Transparent: Stakeholders can verify transactions in real time
  4. Automated: Smart contracts can trigger payments or alerts based on conditions
  5. Linked to Digital Twins & NFTs: Connects physical batches with digital verification

5. Benefits of Demonstrating Ledger Transactions

StakeholderBenefit
Farmers / CooperativesTransparent proof of work, timely payments
Exporters / BrandsVerifiable provenance, reduced fraud
InvestorsAudit-ready ESG and ROI tracking
RegulatorsSimplified monitoring of permits and compliance
ConsumersAssurance of authenticity and sustainable sourcing

6. Summary

Digital ledger transactions in agarwood supply chains:

  • Record all key activities from plantation to consumer
  • Ensure immutable proof of authenticity and compliance
  • Support smart contract automation for payments and batch verification
  • Provide real-time traceability and transparency for stakeholders
