Problems solved by technology
However, when blockchain products are used in some application scenarios such as government or commercial organizations, not all blockchain participating nodes have sufficient resources and necessity to become nodes participating in blockchain consensus; Data security considerations, when personal privacy or national security-related data are involved in the blockchain system, it is not appropriate to adopt the universal data peer-to-peer blockchain deployment method
It can be seen that the single-layer (that is, peer-to-peer) P2P scheme is not suitable for the above-mentioned various application scenarios
In addition, for a blockchain network that adopts a peer-to-peer P2P scheme, nodes usually randomly obtain the data they want from other nodes, but this process usually takes a long time, which seriously affects the efficiency of data acquisition

A data processing method and related devices based on a blockchain network, wherein the method includes: receiving a data acquisition request sent by a target business node; according to the data type and data identification set of the data that the target business node needs to acquire carried by the data acquisition request; and The data storage information of the nodes in the recorded blockchain network determines the target node set from the nodes included in the blockchain network; the feedback information carrying the node information included in the target node set is sent to the target business node, and the feedback information is used for The target service node is instructed to obtain required data from corresponding nodes according to the node information included in the target node set. In this way, access nodes can be reasonably suggested for business nodes, so as to effectively improve the efficiency of data acquisition.
Description
technical field [0001] The present application relates to the field of blockchain technology, and in particular to a data processing method based on a blockchain network, a data processing device based on a blockchain network, a computer device, and a computer-readable storage medium. Background technique [0002] With the advent of the era of science and technology and the development of the mobile Internet, the pace of network change is also getting faster and faster. The process of realizing information fusion in the same field or multiple fields and providing customers with comprehensive information solutions is also facing the improvement of the system structure. , Support new challenges such as shifting the center of gravity. Therefore, as a specific implementation of distributed ledgers, blockchain technology has gradually become the preferred method for storing and transaction data in various fields by virtue of its natural advantages in storing and managing data. ...
