Abstract
The traceability system is significant to consumers because it can protect the health of consumers and the stability of society. With the development of blockchain technology, it is concerned by researchers of the traceability system because of its immutability and consensus mechanism. For guaranteeing the confidentiality of core data, it is necessary to control data permissions in the supply chain. However, the existing blockchain authority management frameworks mostly concentrate on the medical field and the Internet of Things (IoT). They have to take a long time to reach consensus and store lots of data in the chain. The most important is that the number of transactions submitted per second has always been a bottleneck. In this paper, we proposed an authority management framework used to control the authority of different roles in the traceability system. It pays attention to store small amounts of data on the chain, optimize the consensus rate, and increase the number of transactions per second (TPS). We design a simple experiment to contrast the performance of our framework and the MedRec [1] framework, and the results show that our frameworkâs consensus rate and TPS are better than the MedRec [1].
