Abstract: Counterfeit protection is a serious concern for businesses, as it can compromise consumer safety and damage a company's reputation. To address this issue, researchers have conducted a review of available technologies and found that blockchain-based solutions offer several advantages over traditional methods. The use of REST APIs enables secure and transparent tracking of products through the supply chain, while smart contracts facilitate automatic ownership transfers. The traceability provided by blockchain technology allows stakeholders to track a product's origin and journey, improving security and transparency. Implementing a blockchain-based supply chain management system can also improve efficiency and reduce costs associated with lost or misplaced items. This research paper advocates for businesses to invest in advanced technologies like blockchain to protect their supply chains and ensure the safety and authenticity of their products. The system described in the paper involves generating unique identification numbers (UIDs) and associating them with products during the manufacturing process with QR codes and scratchable film for consumer access, while also emphasizing the need for businesses to adopt innovative technologies to maintain competitiveness and customer trust.
