A blockchain is a chained data structure of distributed, decentralized storage. It is a distributed accounting book, all records are completed by a plurality of nodes together, and each node has a complete accounting book. The most significant features of the blockchain itself are distributed, decentralized, and information non-tamperable. But the data searching speed and the data formatting processing are inherently insufficient. A database is a repository built on computer storage devices that organizes, stores, and manages data according to certain data structures. The characteristics of the database comprise redundancy reduction of data, independence of the data and centralized control of the data.
The invention combines the block chain and the database, so that the database system not only has the characteristics of distribution, decentralization, information non-tampering and auditability of the block chain, but also has the characteristics of quick query and elegant data structure of the traditional database.

In a specific embodiment of the present invention, the service layer mainly implements the service logic of log system management. On one hand, the service layer receives the user operation instruction transmitted by the display layer, and then the service layer performs classification management on the operation instruction and transmits the operation instruction after the classification management to the data layer. On the other hand, the service layer receives feedback information corresponding to the user operation instruction transmitted by the data layer, and then the service layer performs classification management on the feedback information and transmits the feedback information after the classification management to the display layer. Preferably, the classification management includes content management, user management, system setting, statistical reporting, system log management, and the like.
In an embodiment of the present invention, the data layer is located between the service layer and the database, and mainly processes the operation instruction of the front-end user and the data information transmitted by the database. On one hand, the data layer receives the operation instruction after the classification management transmitted by the service layer and converts the operation instruction into a data processing operation instruction. Then, the data layer transmits the processing operation instruction to the database so as to perform corresponding operation on the data information in the database. On the other hand, the data layer receives feedback information corresponding to the user operation instruction transmitted by the database, and then transmits the feedback information to the service layer. Preferably, the design and operation of the data layer adopt a block link technology, so that the privacy of information on the block link, the security of data and the non-tamper property are ensured.
The designer stores the operation instructions related to the database in the form of data on the block chain network formed by mutually linking all the nodes of the block chain, and any node in the block chain network can acquire the instructions related to the database operation. In the invention, each instruction for database operation is recorded into one transaction, namely one transaction corresponds to one database operation, and the blockchain network records all operations for the database in a transaction mode.
