Medicine Supply Chain Management Using Blockchain

The prevalence of counterfeit medicines poses a significant threat to public health and safety, largely due to the opaque nature of traditional medicine supply chains. This research introduces a blockchain-based solution designed to bring transparency, traceability, and enhanced security to the medicine distribution process. The proposed system records every transaction in the supply chain, thereby preventing tampering and ensuring the authenticity of pharmaceutical products. Smart contracts are utilized to automate the verification and transfer of products between stakeholders such as manufacturers, distributors, and retailers. A decentralized application (DApp) was developed using React to facilitate user interaction, while the backend was implemented using the Truffle framework and connected to a local Ethereum blockchain via Ganache and Web3.js. The system supports real-time tracking of medicines and reduces dependency on intermediaries, which not only improves operational efficiency but also enhances the overall integrity of the supply chain. This blockchain-based approach represents a significant advancement over conventional methods by offering a transparent, tamper-resistant, and verifiable solution for medicine supply chain management.
