ProvenanceChain: Product Authenticity Tracking
How GetPost Labs approaches supply chain transparency. Blockchain-backed provenance from mine to consumer with instant QR verification.
Executive Summary
The Problem: Retailers can't prove product authenticity from source to shelf. Manual certificate verification takes 20 minutes per item and still can't catch sophisticated forgeries.
The Solution: ProvenanceChain records every supply chain touchpoint immutably on blockchain. QR code scanning provides instant verification for customers and staff.
The Outcome: Customer trust increases because provenance is verifiable, not just claimed. Returns due to authenticity concerns drop dramatically.
The Challenge
Understanding the problem space
"Customers were questioning whether our diamonds were genuine. We had no way to prove provenance from mine to display case."
— Owner, Prestige Fine Jewellers, Sydney
Product authenticity is a growing concern across luxury goods, pharmaceuticals, and food supply chains. Paper certificates can be forged. Manual verification is slow and unreliable. Customers are increasingly demanding proof, not promises.
When a competitor was exposed selling lab-grown diamonds as natural, customer trust across the entire industry dropped. Returns due to "authenticity concerns" spiked, affecting even legitimate retailers with genuine products.

Core Capabilities
How Trust Is Built
Verifiable provenance, not paper promises
Customer trust increases when authenticity is provable at every stage:
Product Verification
Customer asks "is this real?" Staff shows paper certificate. Customer has no way to verify the certificate itself.
Customer scans QR code on product tag. Full journey from mine to store displayed instantly with blockchain verification.
Certificate Validation
Staff manually checks certificate number against issuer database. Takes 20 minutes. Sophisticated forgeries still pass.
System validates certificate hash against blockchain record. Forgeries detected instantly. Result in under 2 seconds.
Dispute Resolution
Customer claims product is fake. Store has paper trail that may or may not prove authenticity. Refund given to avoid conflict.
Complete blockchain record proves every touchpoint. Disputes resolved with verifiable evidence. Returns drop from 12% to 1%.
BPMN Workflow
The business process modelled
Product Authentication Flow
User Journey
Product Authentication Journey
Scenario: Customer wants to verify authenticity of a 1.2ct diamond ring before purchase at Sydney CBD store.
Customer asks "How do I know this diamond is genuine and ethically sourced?"
Scans QR code on ring tag using tablet. ProvenanceChain instantly retrieves blockchain record
Shows complete provenance: Mined Botswana → Cut Antwerp → GIA Certified → Shipped Sydney. Each step verified on blockchain
GIA certificate #2195847362 validated. Kimberley Process compliance confirmed. No conflict diamond flags
Turns tablet to customer showing visual journey map with timestamps, photos from each stage, and certificates
Customer satisfied with transparency. Proceeds with purchase knowing full provenance
New owner registered on blockchain. Customer receives digital certificate with QR code for future verification
Outcome: Customer confident in purchase authenticity. Full chain of custody transferred. Zero returns due to authenticity concerns.
