Blockchain communication resource integration consensus method for data governance

Abstract

The invention discloses a blockchain communication resource integration consensus method for data governance, and belongs to the technical field of blockchain technology and data governance. The improved blockchain consensus mechanism is based on a PBFT consensus mechanism, specifically, all nodes are randomly divided into a plurality of groups, communication nodes and consensus nodes are selected according to the credibility, one communication node is randomly selected from the consensus nodes with the credibility being front 10% in each group, and the rest are the consensus nodes. The consensus process is divided into a request stage, a pre-preparation stage, a preparation stage, a submission stage and a reply stage; messages generated in the consensus process are all written into a local log, all nodes can view the local log, communication nodes are prevented from tampering voting information, and therefore the decentralization characteristic of the block chain is ensured. According to the method, the enthusiasm of the nodes can be greatly improved, the credible nodes can be identified, the message complexity is greatly reduced, the communication resource consumption is reduced, and the security and efficiency of the system are improved.

Description

Technical field [0001] The present invention relates to a block chain communication resource integration consensus of data management, belonging to the field of block chain technology and data management technology. Background technique [0002] The era of big data, data source is constantly generated and independently aggregated to multi-party data collectors, and data has become the key to the competition between enterprises and important factors affecting national competitiveness. The data governance has become the key areas and important ways of corporate governance and national governance. . The block chain is essentially a detrimentary distributed database that has a natural advantage in increasing the transparency of the big data value implementation process, providing feasibility in addressing the key issues of current data governance. The consensus mechanism is a consistent agreement with the block chain system. Now the common consensus mechanism of the league chain is P...

Problems solved by technology

The consensus mechanism is an agreement reached by the blockchain system. Now the common consensus mechanism of the alliance chain is PBFT, that is, the practical Byzantine fault-tolerant algorithm. In the consensus process of the ordinary PBFT algorithm, all nodes participate, resulting in high consumption of communication resources and failure to identify trusted nodes.
