Abstract

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.

본 논문에서는 위조 약물, 투명성 부족 및 추적 문제 등 전통적인 시스템에서 발생하는 문제를 해결하기 위해 블록체인 기반의 의약품 유통 추적 시스템을 제안한다. 제안한 시스템은 권한 증명(PoA) 합의 메커니즘을 사용하여 신뢰할 수 있는 노드 검증을 통해 거래 효율성과 신뢰성을 향상시키고, 계산 및 에너지 부담을 줄이며, 거래 확인 속도를 가속화한다. 시뮬레이션 실험 결과, PoA 메커니즘은 거래 처리량, 지연 시간 및 동시성을 유의미하게 개선하여 시스템의 효율성 및 실시간 요구 사항을 충족하는 것으로 나타났다. 제안한 시스템은 규제 효율성 및 공공 약물 안전을 개선하는 것을 목표로 하며, 기존 시스템보다 30% 더 나은 성능을 보였다. 향후 연구에서는 PoA의 탈중앙화 최적화, 크로스 체인 기술 탐색 및 개인정보 보호 강화가 요구 된다.
