Problems solved by technology

[0006] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a trusted log recording method based on the block chain, which is used to solve the problem that the existing distributed log system and the existing block chain infrastructure model are not suitable for The log system and the practical Byzantine fault-tolerant algorithm have the problem that the consensus rate decreases significantly with the increase of the number of nodes in the system

Embodiment

[0054] A blockchain-based approach to trusted logging such as figure 1 shown, including the following steps,

[0055] S1. Register and review ordinary nodes, and the ordinary nodes that pass the review will be managed at the management node of the blockchain system, specifically:

[0056] Ordinary nodes submit node information to the management terminal, the administrator logs in to the management terminal to review the node information, and writes the node information into the database after the review is passed; the node information includes IP address, node public key, node access address, operation authority, The organization to which the node belongs;

[0057] The common nodes are reviewed, and the normal nodes that pass the review are managed by the management node of the blockchain system. The management includes dynamic registration / deregistration, key distribution, authority distribution, and authority query.

[0058] S2. For ordinary nodes that have successfully re...

Abstract

The invention discloses a trusted log recording method based on blockchain, provides an overall framework suitable for a distributed log system based on blockchain, and provides each module and each log in the overall architecture. Layered specific design; especially in the consensus layer of the distributed accounting module, the traditional practical Byzantine fault-tolerant algorithm is improved by combining multi-version concurrency control methods, random algorithms and event monitoring mechanisms. The invention is used to solve the lack of trusted log function for further consensus verification of the correctness of the log generated by the node and the operation authority of the node in the existing distributed system, and to improve the problem of large communication volume of the traditional practical Byzantine fault tolerance algorithm.

Description

technical field [0001] The invention relates to the research field of computer application system log processing, in particular to a blockchain-based trusted log recording method and system. Background technique [0002] With the rapid development of computer technology and the continuous improvement of Internet speed, various computer application systems emerge in an endless stream, and the log system is a very important functional component in a complete application system. It provides functions such as log collection, log storage, log query, and log analysis. The application system can track and trace the user's various operation processes in the system through log query, and at the same time provide abnormal alarms through log analysis. Currently, mainstream open source distributed log systems include Scribe, Chukwa, Kafka, and Flume systems. [0003] The Scribe system is an open-source real-time distributed log collection system developed by Facebook during the operat...
