Problems solved by technology

Most of the existing consortium chains divide the entire blockchain network into different consensus groups, and realize the expansion of transaction throughput by diverting transactions to different blockchains. However, it is difficult to achieve global The consistency of transactions, while the relatively fixed consensus members lead to a decrease in the fairness of the consensus process restricts the application of technology and the promotion of business

Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] At present, the medical industry suffers from large-scale data quality problems - partly due to the fact that multiple medical institutions have not done global consistent verification of the EHR (electronic medical record) of the same patient, so that the medical institutions cannot obtain the latest version of the patient's EHR when the patient sees a doctor, and cannot Accurately diagnose the patient's condition.

[0046] This embodiment provides a dynamic consensus method of the alliance chain based on the primary and secondary layers, which is used to solve the data quality problem in the medical industry. The schematic diagram of the two-layer alliance chain architecture is as follows figure 1 As shown, the two-layer consortium chain includes the main layer blockchain and the sub-layer blockchain; Each medical institution has a unique iden...

Abstract

The invention discloses a consortium chain dynamic consensus method based on the primary and secondary double layers, which belongs to the technical field of blockchain. The method of the present invention is based on the main layer-sub-layer double-layer alliance chain structure, the main layer blockchain stores and maintains the global business data of the alliance, and the sub-layer blockchain maintains its own local business data by each subject. The selection process of consensus nodes is divided into dynamic selection of verification nodes and construction nodes to improve the flexibility of the alliance chain. The method of the invention realizes the scalability and consistency of transactions by means of the double-layer structure of the blockchain and the dynamic selection of consensus nodes, improves the business processing efficiency of the alliance chain, and realizes the easy scalability and high availability of the alliance chain system. , to enhance the ability of blockchain technology to support big data services and respond to various business scenarios.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a dynamic consensus method of an alliance chain based on a master-slave layer. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method for programming and manipulating dat...
