Blockchain Based Log System

The logging system records the logs generated by the software so that the administrator can handle the problems that occur. However, the traditional log system is not secure enough and the stored logs are easily falsified. As a decentralized distributed storage technology, the blockchain can ensure that the blockchain network works normally in the presence of a few malicious nodes or failed nodes. So we use the blockchain to store the logs, which improves the security of the log system. In order to improve the performance of the blockchain, we use a voting-based consensus algorithm as a blockchain consistency protocol. This article introduces the architecture and implementation of the log system and verifies the feasibility of the system through experiments.
