2.3. Improving Traceability with Blockchain
Traceability is one of the most compelling use cases for blockchain in supply chains. Every transaction or product movement on the blockchain is time-stamped and linked to a specific event or transaction. This makes it possible to track a product from its source, through the manufacturing process, to its final destination.
- Tracking Origins and Movements: Blockchain allows stakeholders to trace the origin and journey of a product, such as raw materials, across multiple touchpoints in the supply chain.
- Provenance Verification: For industries like luxury goods or pharmaceuticals, blockchain can authenticate the provenance of a product, ensuring its authenticity.
- Sustainability: Blockchain enables companies to demonstrate the ethical and environmental impact of their products by tracking the source of raw materials and the conditions under which they were produced.
2.4. Reducing Fraud and Counterfeiting
Since blockchain records all transactions in an immutable ledger, it is virtually impossible to alter the data. This makes it an ideal tool for combating fraud and counterfeiting in supply chains. By linking products to verified blockchain records, companies can ensure that each product is genuine and traceable to its original source.
- Example: A pharmaceutical company can use blockchain to track a drug’s entire journey from the manufacturer to the pharmacy, ensuring that the product is not tampered with or counterfeit.
- Impact: Blockchain reduces the chances of fraud, increasing trust among consumers and protecting brand integrity.
