Design of a Cold Chain Drug Traceability System Based on Reputation Dynamic Reserve Proof Mechanism and SPBFT Hybrid Consensus Algorithm
The research aims to design an efficient and safe cold chain drug traceability system to im-prove the transparency and credibility of the drug supply chain.A cold chain drug traceability system was designed based on reputation mechanism and Byzantine fault-tolerant aggregation signature con-sensus algorithm according to Schnorr.By combining blockchain technology and Internet of Things technology,the Byzantine fault-tolerant aggregation signature consensus algorithm based on Schnorr was adopted to improve consensus efficiency and security.At the same time,reputation mechanism was introduced to encourage nodes to participate and maintain system security.The experimental re-sults show that as the number of nodes increases,the throughput of the system decreases relatively flat,and the final average throughput can reach 516 TPS.The system has advantages in ensuring that drug traceability information is not tampered with and efficient consensus is achieved.
