With the development of the Internet, many log data are generated in the server. How to ensure the security of log data in the server is a problem that needs to be solved. At present, log data storage in most servers relies on a centralized log database or local files. With the increase of running time and scale, there are great challenges in data security and stability. Meanwhile, attackers can tamper with the server's logs to evade tracking. To solve the above problems, this paper proposes a secure multi-level log data storage system based on permissioned blockchain and permission-less blockchain, with high throughput and low cost. In addition, different encryption methods are adopted for different levels of log data to provide higher security
