Enhancing Drug Supply Chain Management with a Scalable Multi-Layered Blockchain Architecture

The healthcare industry's transition to online platforms in recent years has brought attention to privacy, scalability difficulties, and data security. Blockchain technology, renowned for its segregated, impregnable, and unchangeable characteristics, arises as a feasible resolution for these urgent problems. In order to manage the drug supply chain and exchange EHRs (Electronic Health Records), a novel framework is presented in this paper. Scalability, security, traceability, data integrity, and safe data sharing are all taken care of by the system. With a focus on patient-centric healthcare, the framework implements a hierarchical structure with five layers and transactions. This is accomplished by giving patients broad access control over their medical records. This access enables more efficient operations, such as insurance claims, while upholding strong security safeguards. Our parallelism technique reduces network traffic while significantly improving scalability and transaction throughput. The Caliper benchmark performance tests show a slight rise in CPU usage for certain transactions, although parallelization significantly reduces this. The RAM needs remain relatively constant. In addition, our approach significantly decreases network congestion while increasing transaction processing speed thrice. The framework guarantees patient information confidentiality, data accuracy and consistency, user access management, and the ability to exchange information with other healthcare systems by established standards. Furthermore, it offers clarity and immediate tracking of medication distribution, enabling decision-makers to make informed decisions based on practical information. Our framework establishes a vital standard for cutting-edge, adaptable, and protected solutions as healthcare progresses.
