Abstract

The invention provides a data acquisition method and device and a storage medium, and the method comprises the steps: transmitting request information of first data to each node, so as to enable eachnode to return the corresponding first data; and comparing and verifying the first data returned by each node according to a verification rule of a consensus rule pre-configured by the alliance chain,and confirming the verified first data as correct first data. According to the invention, the data acquired by the client from the alliance chain is ensured to be correct data.

Description

Technical field [0001] This application relates to the field of blockchain technology, and specifically relates to a data acquisition method, device and storage medium. Background technique [0002] In the existing alliance chain technology, since the node connected by the client may be faulty or a malicious node, the client cannot request correct data from the connected node. Summary of the invention [0003] In view of the aforementioned shortcomings or deficiencies in the prior art, it is desirable to provide a data acquisition method, device and storage medium that ensure that the data obtained by the client from the alliance chain is correct data. [0004] In the first aspect, the present invention provides a data acquisition method suitable for a client. The client establishes a connection with each node of the alliance chain. The above method includes: [0005] Send the request information of the first data to each node so that each node can return the corresponding first data...
