Blockchain technology is proving transformative in various industries by enhancing supply chain transparency, traceability, and efficiency. Here are some case studies and real-world applications illustrating how blockchain has been applied to tackle specific challenges and improve operations in supply chains globally.



1. Walmart and IBM’s Food Trust Blockchain



  • Objective: Improve food safety and traceability.

  • Solution: Walmart partnered with IBM to develop the Food Trust Blockchain, which tracks food items from farm to table. This initiative addresses food safety issues by quickly identifying sources of contamination and reducing food waste.

  • Outcome: Walmart was able to reduce the time needed to trace food origins from seven days to just 2.2 seconds. By accessing complete supply chain information, Walmart can quickly respond to foodborne illness outbreaks, minimizing risks to consumers and reducing recall costs.





2. Maersk and IBM’s TradeLens



  • Objective: Enhance transparency and efficiency in global shipping.

  • Solution: TradeLens is a blockchain-powered platform created by Maersk and IBM to streamline supply chain processes in the shipping industry. It enables stakeholders, including shippers, port operators, customs officials, and logistics providers, to access a shared, real-time record of shipment data.

  • Outcome: By digitizing and automating paper-based processes, TradeLens has reduced transit times and paperwork, leading to an approximate 40% improvement in shipping efficiency. It also allows for quicker customs clearance, reducing delays at ports and saving costs across the shipping ecosystem.





3. Provenance: Transparency in Ethical Sourcing



  • Objective: Ensure ethical and sustainable sourcing in consumer goods.

  • Solution: Provenance is a blockchain platform that helps brands track product origins and verify ethical standards, like fair labor practices and environmentally friendly sourcing. Provenance focuses on supply chains for goods like tuna, coffee, and clothing, providing consumers with transparent product histories.

  • Outcome: The platform has successfully empowered companies like Unilever and The Co-operative to validate and share the ethical origins of their products with consumers. This boosts customer trust and loyalty by allowing consumers to make informed purchasing decisions.





4. De Beers’ Tracr Platform for Diamond Traceability



  • Objective: Prevent conflict diamonds from entering the market and assure diamond authenticity.

  • Solution: De Beers created Tracr, a blockchain-based system, to trace diamonds from mine to retail, ensuring they are conflict-free and meet industry standards. Each diamond is given a unique identification code, recorded on the blockchain to authenticate its journey through the supply chain.

  • Outcome: Tracr enhances transparency and boosts consumer trust in De Beers’ diamonds by verifying that the diamonds are ethically sourced. The platform has been particularly effective in increasing customer confidence and deterring copyright diamond sales.





5. Pharmaceutical Industry: copyright and MediLedger



  • Objective: Combat copyright drugs and improve pharmaceutical supply chain security.

  • Solution: copyright and other pharmaceutical companies joined the MediLedger Network, a blockchain-based platform designed to verify drug authenticity and track medications from manufacturing to the point of sale. This platform addresses the issue of copyright drugs entering the market by verifying the legitimacy of pharmaceutical products.

  • Outcome: MediLedger provides a secure, tamper-proof record of each drug’s journey, reducing the risk of copyright medications and allowing stakeholders to verify product authenticity. The platform has successfully streamlined compliance with regulatory requirements, including the Drug Supply Chain Security Act (DSCSA) in the United States.





6. Ford and IBM: Tracking Cobalt for Ethical Sourcing



  • Objective: Ensure ethical sourcing of cobalt for electric vehicle (EV) batteries.

  • Solution: Ford partnered with IBM to create a blockchain system for tracking cobalt mined in the Democratic Republic of Congo, where ethical and environmental concerns about mining practices are prevalent. Blockchain technology allows Ford to verify that the cobalt used in their EV batteries is sourced responsibly.

  • Outcome: By using blockchain to document and trace each step of the cobalt supply chain, Ford can ensure that materials used are sourced ethically. This provides transparency and builds consumer trust, as Ford can prove their commitment to responsible sourcing.





7. Nestlé and OpenSC: Blockchain for Sustainable Food Tracking



  • Objective: Promote sustainable sourcing and offer transparency to consumers.

  • Solution: Nestlé partnered with OpenSC, a blockchain platform for tracking food origins and sustainability. They began by tracking milk from New Zealand and soon expanded to palm oil from America. This blockchain system allows consumers to see the sustainable journey of the products they buy.

  • Outcome: The project provided Nestlé with a way to authenticate their sustainability claims, enhancing transparency and encouraging ethical consumerism. Through OpenSC’s blockchain, consumers can scan a product to view its entire journey, reinforcing Nestlé’s commitment to sustainability.





8. Bumble Bee Foods: Blockchain for Seafood Traceability



  • Objective: Improve transparency in seafood sourcing and prevent illegal fishing practices.

  • Solution: Bumble Bee Foods uses blockchain to trace yellowfin tuna from Indonesian waters to grocery stores. With the help of the SAP Cloud Platform blockchain, the company records each step of the tuna’s journey, from fishing vessel to store shelves.

  • Outcome: By providing a complete view of each tuna’s journey, Bumble Bee enhances transparency and consumer confidence. Shoppers can access details about the product’s origin and journey, supporting ethical and sustainable fishing practices and reducing the risk of illegally sourced seafood in the supply chain.





9. Honeywell: Blockchain in the Aerospace Industry



  • Objective: Improve transparency and efficiency in parts traceability.

  • Solution: Honeywell uses blockchain to track and authenticate aerospace parts. Through a platform called GoDirect Trade, Honeywell ensures that parts are genuine and meet industry standards, giving airlines, suppliers, and buyers verifiable data on each part’s history.

  • Outcome: The platform has cut down on paperwork, reduced lead times, and allowed buyers to confirm the authenticity of each part in real-time. This improves safety in the aerospace industry and reduces risks related to copyright or non-compliant parts.


Blockchain technology is transforming supply chain management across industries by enhancing transparency, security, and efficiency. These case studies demonstrate that blockchain can address diverse challenges, from product traceability in food safety to ethical sourcing in the mining and manufacturing sectors. As blockchain adoption grows, it will continue to reshape supply chains globally, creating more transparent, secure, and ethical practices across industries Live Draw Taiwan.

With real-world applications already delivering positive results, blockchain promises to play a vital role in the future of supply chain management, providing stakeholders and consumers with reliable, accessible, and verifiable data throughout product lifecycles.
