This paper proposes a blockchain-based pharmaceutical circulation traceability system to address issues such as counterfeit drugs, lack of transparency, and traceability challenges in traditional systems. The system employs the Proof of Authority (PoA) consensus mechanism, which enhances transaction efficiency and reliability through trusted node verification, reduces computational and energy burdens, and accelerates transaction confirmation. Simulation experiments show that the PoA mechanism significantly improves transaction throughput, latency, and concurrency, meeting the system's efficiency and real-time requirements. The system aims to improve regulatory efficiency and public drug safety, with performance 30% better than existing systems. Future research will focus on optimizing PoA's decentralization, exploring cross-chain technology, and enhancing privacy protection.
