Data processing method based on block chain network and related device

Abstract

The invention discloses a data processing method based on a block chain network and a related device. The method comprises the following steps: receiving a data acquisition request sent by a target service node; determining a target node set from the nodes included in the blockchain network according to the data type and the data identifier set of the data needing to be acquired by the target service node carried by the data acquisition request and the recorded data storage information of the nodes in the blockchain network; and sending feedback information carrying the node information included in the target node set to the target service node, wherein the feedback information is used for indicating the target service node to acquire required data from the corresponding node according tothe node information included in the target node set. By adopting the mode, the access node can be reasonably suggested for the service node, so that the data acquisition efficiency is effectively improved.

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. ...

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
