Problems solved by technology

However, when the number of nodes increases and the number of requests increases sharply, the performance of the highly robust Byzantine fault-tolerant algorithm will drop rapidly, and the prevention of node attacks is also relatively weak, making it difficult to meet the requirements of data security and real-time on-chain

Embodiment Construction

[0043] According to specific embodiments and drawings, the related technologies involved in the present invention are described and explained in detail. In the present invention, except for the content to be mentioned below, all other technologies and methods related to implementation conditions are common knowledge and generally accepted common sense in this field and its related fields.

[0044] The present invention proposes a method for secure real-time uploading of alliance chain data based on high robustness Byzantine fault tolerance. This method is used in the alliance chain network, and all nodes in the network follow the malicious node supervision mechanism; the network allows dynamic addition of nodes, if there are new Adding nodes to join will enter the process of dynamically adding nodes. After the increase, if the number of nodes exceeds the set threshold, the partition management and partition consensus mechanism will be started; each message in the network includ...

Abstract

The invention provides a high-robustness Byzantine fault tolerance-based alliance chain data security real-time uplink method, which sequentially comprises five steps of request forwarding, pre-preparation, preparation, submission and account book writing, and provides a dynamic view rotation and rapid batch processing mechanism. The method can improve the capability of an alliance chain network to process a large amount of data uplink requests in a short time, and can use partition management and partition consensus mechanisms under the situation of more nodes in a consensus network to realize data uplink with lower delay, thereby achieving the effect of real-time uplink. Meanwhile, a malicious node monitoring mechanism is additionally arranged in the method, so that the Byzantine behavior of malicious nodes can be prevented, and the robustness of the alliance chain network is improved.

Description

technical field [0001] The invention relates to a Byzantine fault-tolerant algorithm of a consortium chain, belongs to the technical field of block chains, and in particular relates to a method for secure real-time uploading of consortium chain data based on high robustness Byzantine fault tolerance. Background technique [0002] With the widespread popularity of the Internet in various industries, the speed and security of data transmission, storage, and security have been greatly challenged: on the one hand, data is easily intercepted by hackers during transmission, or messages cannot be delivered to the target due to network fluctuations On the other hand, due to the surge in the number of users, the speed of data processing by the server will be greatly tested, and the synchronization of data between servers will also become one of the architectural considerations. [0003] The distributed consensus network of blockchain has the characteristics of decentralization, preve...
