Abstract

The invention provides a query method and a system based on a multi-source data structure block chain. According to the method, a matching data structure adapting to the storage requirement and the subsequent query requirement of the information is selected according to the condition of the information needing to be loaded into the local account book of the block chain; distributing the information to a data processing node applying the matching data structure; converting the information into blocks by the distributed data processing nodes according to a matching data structure; enabling the data processing node to link the block to a local account book through hash head verification; sharing the updated local account book among the distributed nodes of the block chain, and forming a consensus for the updated local account book; and obtaining the data processing node to which the information is allocated by the distributed node according to a local account book , and querying the information from the allocated data processing node. According to the method, the compatibility of a multi-source data structure is improved, the limitation of solidification of an account book structure and a consensus mechanism of a block chain is overcome, and the flexibility and the applicability are enhanced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a query method and system based on a multi-source data structure block chain. Background technique [0002] In many scenarios such as e-commerce and Internet finance, a highly reliable, tamper-proof, and traceable information query mechanism is required, such as verifying transaction records, calling credit information, and so on. This process involves the transmission, interaction, response, storage and other links of data information. Since these links are all realized by means of the Internet, a robust, reliable and secure network architecture is the basic guarantee. [0003] The traditional network architecture is based on the background server of the relevant platform as the central node. All information is stored on the background server, and the central node responds to the query request, interacts with the terminal node as the requester, and transmits the requested ...
