Can Blockchain Ensure Authenticity in Retail Supply Chains?

Counterfeit goods cost the global economy over US$500 billion annually, eroding consumer trust and damaging brand reputation. Traditional supply chains often struggle to track products accurately across various intermediaries, leading to inefficiencies and vulnerabilities. Blockchain technology addresses this issue by recording every transaction in an immutable, shared ledger, fostering transparency, accountability, and product authenticity. 

Retail leaders now view blockchain as more than a technological upgrade; it is a foundation for verified provenance and enhanced consumer confidence. The emphasis is transforming how retailers create, share, and validate information throughout the supply chain, improving operational efficiency and minimising risk. 

Why Provenance Matters More Than Ever 

Consumers have moved beyond accepting a simple "authentic" label; they seek verifiable proof of a product's origins, including where, when, and how it was made. This expectation spans luxury goods, electronics, pharmaceuticals, and food items. 

Luxury brands like LVMH and Prada utilise the Aura blockchain consortium to enable customers to trace a product's journey from raw materials to retail. For instance, LVMH's blockchain platform tracks each step in producing a Louis Vuitton handbag, from material sourcing to shipping. Customers can scan a QR code to verify authenticity and view the item's history, significantly reducing the risk of counterfeit handbags in secondary markets. 

Walmart employs blockchain to trace food items such as mangoes and pork from farms to stores. The blockchain system allows Walmart to trace mango shipments in just 2.2 seconds, compared to nearly a week with traditional methods. This solution integrates farm data, logistics records, and distribution checkpoints, enabling swift action in contamination or product recalls. The model has since expanded to include leafy greens and meat products across the United States. 

For retailers, provenance data protects against counterfeits, enhances brand reputation, reinforces sustainability commitments, and mitigates operational risks by providing precise insights into product movement and handling. 

How Blockchain Strengthens Supply Chain Provenance 

Blockchain establishes a shared version of truth among suppliers, manufacturers, logistics providers, and retailers. Each transaction forms a new data block linked to the previous one. Once validated, this information cannot be altered without consensus from all parties. 

Key benefits include: 

• Transparency and Traceability: All stakeholders can view product movement in real time, eliminating information silos and reducing disputes. 
  

• Tamper-Proof Records: Immutable data is proof of origin and handling at each stage. 
  

• Faster Recalls: Retailers can quickly identify and isolate affected batches, minimising financial and reputational damage. 
  

• Simplified Audits and Compliance: Regulators can access timestamped records without manual reconciliation. 
  

By integrating blockchain with IoT sensors, RFID tags, or QR codes, retailers can connect physical goods directly to digital records, ensuring that provenance data travels with the product rather than being confined to documents or isolated systems. 

Combating Counterfeiting with Blockchain 

Counterfeiting costs fashion and electronics brands billions each year. Even advanced tags and holograms can be compromised when counterfeiters replicate packaging or exploit traceability gaps. Blockchain mitigates this risk by providing each product with a unique, verifiable digital identity. 

Each item is assigned a non-fungible identifier linked to its manufacturing data, material sources, and ownership records. When customers scan a QR code, they can confirm the product's authenticity in seconds. Any discrepancies indicate tampering or duplication. 

De Beers uses its blockchain platform Tracr to authenticate diamonds, ensuring each stone meets ethical and geological standards. Tracr tracks the diamond's journey from mine to retailer, verifying ethical sourcing and compliance with conflict-free regulations. This information is accessible to customers and regulators, bolstering confidence in the diamond industry and reducing illicit trade. 

Nike's CryptoKicks connects physical sneakers with digital tokens, confirming genuine ownership and tracking resale activity. Each pair is associated with a unique token on the blockchain, automatically updating ownership in the secondary market to prevent fraudulent reselling of counterfeit shoes. 

LVMH also extends blockchain to perfumes, where counterfeit fragrances often infiltrate the market. Each bottle receives a unique digital identity that captures production and distribution events. Retailers and customers can verify authenticity through a QR code, safeguarding brand reputation and revenue. 

This approach fosters a closed loop of trust, where retailers confirm supplier integrity, consumers validate authenticity, and counterfeiters encounter significant barriers. 

Integration Challenges and Strategic Considerations 

Despite its potential, blockchain adoption requires careful planning. Retailers face three primary challenges: 

• Data Accuracy: Blockchain ensures trust only when the input data is reliable. Companies must implement secure data capture systems, verified supplier inputs, and innovative packaging technologies. 
  

• Scalability: Managing millions of product entries daily requires high-performance systems and efficient consensus mechanisms. Hybrid setups that combine on-chain and off-chain data can help balance cost and performance. 

  
  

• Ecosystem Collaboration: The value of blockchain increases with consistent participation from suppliers, logistics partners, and regulators. Establishing clear governance structures and shared data standards is essential. 
  

Many retailers begin with pilot projects for high-value or high-risk items before scaling. Network alignment and consistent participation are crucial for long-term success. 

Illustrative Examples of Industry Momentum 

• Starbucks initiated the "Bean to Cup" program using blockchain to trace coffee from farm to consumer. The platform tracks data at every stage, including farm location, harvest date, and shipping records. Consumers can scan QR codes to learn about farmers, verify sustainable sourcing, and confirm roasting processes. Starbucks reports that this integration has strengthened supplier relationships and boosted consumer confidence in premium coffee products. 

  
  

• Carrefour employs blockchain for over 30 product lines, including poultry, dairy, and fresh produce. Each batch receives a digital record detailing farm origin, transport checkpoints, processing details, and store delivery. Shoppers can scan QR codes for full traceability, including animal welfare practices and processing dates. Carrefour's blockchain initiative has improved recall efficiency, reducing response times and minimising product wastage. 

  
  

• Amazon is exploring blockchain to validate product authenticity within its marketplace. By linking sellers' inventory to blockchain records, Amazon aims to reduce counterfeit listings and enhance trust in third-party products. The platform also tracks shipment and delivery data to prevent tampering during logistics. Early pilots have shown improved accuracy in authenticity verification, enhancing buyer confidence and reducing disputes between sellers and customers. 

  
  

The Expanding Value Network 

Blockchain offers more than transparency; it reshapes business relationships through verifiable data and automated trust. Retailers can implement smart contracts to release payments automatically when quality and delivery conditions are met, reducing disputes, improving cash flow, and strengthening supplier relationships. 

Sustainability tracking becomes precise and auditable. Brands can record carbon footprints, labour practices, and material sourcing on-chain, creating credible, data-backed ESG disclosures that align with tightening global transparency standards. 

Provenance evolves into a strategic asset, allowing retailers to convert verified authenticity into customer trust, loyalty, and operational efficiency.
