Blockchain traceability refers to the use of blockchain technology to create transparent, immutable records of products and transactions across supply chains. By recording each step of a product’s journey—from raw material sourcing to final delivery—blockchain enhances accountability, reduces fraud, and improves consumer trust. This technology holds significant potential for sectors such as food safety, pharmaceuticals, and luxury goods, where provenance and authenticity are critical. Policy implications of blockchain traceability revolve around regulatory adaptation and data governance. Governments and regulatory bodies need to establish frameworks that recognize blockchain records as valid legal evidence, ensuring interoperability and standardization across industries. Privacy concerns also arise, as sensitive business and personal data are recorded on distributed ledgers, necessitating policies that balance transparency with data protection. Additionally, policymakers must address the environmental impact of blockchain operations, promoting sustainable practices within the technology’s infrastructure. Overall, integrating blockchain traceability into regulatory systems can strengthen supply chain oversight, combat counterfeit goods, and enhance consumer protection, but requires careful policy design to maximize benefits while mitigating risks.
