Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0031] A consensus method for heterogeneous alliance chains, such as figure 1 As shown, the specific steps are described as follows:

[0032] (1) Grouping:

[0033] Step 1. Perform initial grouping according to the number of nodes in the initial network environment, and members of each group include A common nodes and V supervisory nodes.

[0034] The algorithm is grouped according to the number of nodes in the initial network environment. The initial division of the group is based on OmniLedger's anti-bias distributed random number for fragmentation. There are A+V members among the group members of a group. In fact, since each supervisory node is in two different groups at the same time, and the supervisory nodes of a group belong to different groups, the actual numbe...

Abstract

The invention discloses a consensus method for heterogeneous alliance chains. Based on the PBFT algorithm, combined with the RAFT algorithm, and using a layered structure, it not only effectively reduces the communication overhead of data transmission between nodes, but also makes it more suitable for application in In the Industrial Internet of Things with a large number of devices and complex communication; and the number of nodes participating in the consensus in the blockchain can be expanded, which increases scalability; in addition, the monitoring mechanism and restart mechanism are added, thereby increasing the fault tolerance rate and maintaining Security to meet the information interaction needs in the medical field.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a consensus method for heterogeneous alliance chains. Background technique [0002] How to ensure the security and privacy of medical data is a core issue in the medical industry. The storage and sharing of medical data involves multiple industries such as the government, research institutes, pharmaceutical factories, and insurance companies, and the information exchange increasingly reflects heterogeneity, complexity, and confidentiality. Traditional secure access technology cannot meet the needs of its information interaction platform for security, low cost, and good scalability. [0003] Blockchain has become the best solution for medical data storage and sharing because of its decentralization, tamper-proof, low cost and ability to manage multi-signature complex permissions, but not all blockchain solutions are suitable for medical applications field. The public cha...
