Smart Contract System Architecture for Pharma Supply chain

Abstract

In this paper, we offer a blockchain-based approach for efficient product tracing in the pharmaceutical supply chain that uses smart contracts and decentralized storage. The smart contract ensures data provenance, eliminates the need for mediators, and provides all participants with a safe, immutable transaction history. We provide the smart contract system architecture as well as the detailed algorithms that regulate our proposed solution’s operating principles. We test and validate it to see how effective it is at improving traceability in pharmaceutical supply chains.
