Embodiment 1

[0072] Step S2.1, calculate the degree of each node in the transaction network. Among them, the degree of the node is the correlation degree of the node, which means

[0074] It is easy to understand that in the Bitcoin transaction network, the higher the degree of a node, the more connected the node is,

[0075] In this embodiment, 0.05% of the nodes are selected from all nodes including the central node and the non-central node

[0076] Step S2.3, initialize the label of the central node and the label of the non-central node. initialization

[0081] In step S3, a community to be displayed is extracted from the community division result to obtain a community to be displayed. specific package

[0088] Step S4.1.2, in the process of generating the edge, query the input address of each edge in the address label set

[0090] When the number of the transaction records is greater than the preset threshold, then count the input locations of the various edges in the total edge set.

Embodiment 2

Embodiment 3

[0136] As shown in Figure 6, the present embodiment provides a digital currency transaction community identification device, which specifically includes:

[0138] The digital currency exchange as in Embodiment 1 is realized when the computer program N3 is executed by the processor N2

[0139] In addition, the method according to the embodiment of the present invention can also be implemented by means of the architecture of the device shown in FIG. 6 . Image 6

Abstract

The present invention relates to a digital currency transaction community identification method, system, device and storage medium, belonging to the field of transaction community identification and visualization, first extracting the original transaction records of Bitcoin, and preprocessing the original transaction records to obtain the processed transaction records ; Use the central node-based label propagation algorithm to divide the processed transaction records into communities to obtain the community division results; extract the communities to be analyzed from the community division results to obtain the communities to be displayed; treat the transactions that the addresses in the displayed communities participate in The records are traversed to generate the total edge set; finally, the community structure diagram is generated and displayed according to the total edge set, which realizes the visualization of the trading community, so that researchers can easily identify the structure and type of each trading community.

Description

A digital currency trading community identification method, system, device and storage medium technical field The present invention relates to the transaction community identification and visualization field of digital currency, especially relate to a kind of based on block chain The digital currency trading community identification method, system, equipment and storage medium. Background technique [0002] Digital currency is an unregulated, digital currency that is usually issued and managed by developers and is Accepted and used by members of the intended community. As a virtual digital currency for peer-to-peer transactions, Bitcoin has a strong Name, its transaction records are packaged into the blockchain by miners. In recent years, more and more researchers want to analyze Bitcoin transactions by Easy Record conducts anti-anonymity research on entities, such as entity identification, transaction pattern identification, community structure identification, etc. ...
