Embodiment 1

[0057] see figure 1 , Figure 9 and Figure 10 , a method for tracking the flow of encrypted currency based on a graph database, the method includes steps:

[0058] S1. Obtain the address and flow of cryptocurrency in blockchain transactions;

[0059] S2. Generate a graph database with the address as the point and the flow direction as the edge;

[0060] S3. Obtain the query address of the cryptocurrency, and query the multi-level transaction path map from the query address according to the query statement of the graph database.

Embodiment 2

[0062] see figure 2 , Figure 9 and Figure 10 , a graph database-based cryptocurrency flow tracking device, including:

[0063] Obtaining module 1, which is used to obtain the addresses and flows of cryptocurrencies in blockchain transactions;

[0064] Generating module 2, which is used to generate a graph database with addresses as points and flow directions as edges;

[0065] The query module 3 is used to obtain the query address of the cryptocurrency, and query the multi-level transaction path map from the query address according to the query statement of the graph database.

[0066] In the implementation of Example 1 and Example 2, by obtaining the address and flow direction of the encrypted currency in the blockchain transaction, the graph database is generated with the address as the point and the flow direction as the edge, and the query address for the encrypted currency is obtained. According to the graph database The query statement queries the multi-level tran...

Embodiment 3

[0071] see image 3 , Figure 9 and Figure 10 , a graph database-based encrypted currency flow tracking identification method, the method includes steps:

[0072] S4. Crawl the address tags of the encrypted currency in the open source blockchain browser to generate an address tag library;

[0073] S5. Update the address tag library to the graph database.

Abstract

The invention belongs to the technical field of block chains, and provides a cryptocurrency flow direction tracking method and device based on a graph database, computer equipment and a computer readable storage medium. The method comprises the steps of obtaining an address and a flow direction of cryptocurrency in a block chain transaction, generating the graph database by taking the address as a point and the flow direction as an edge, and obtaining a query address of the cryptocurrency; querying the multi-level transaction path map starting from the query address according to the query statement of the map database, so that the multi-level transaction path map in the currency transaction network is rapidly displayed, balance transfer change of the encrypted currency address in the transaction link is tracked, full-chain query tracking is achieved, the retrieval and analysis efficiency is improved, and the technical effect of improving the correlation analysis capability is achieved.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, to a method, device, computer equipment, and computer-readable storage medium for tracking the flow of encrypted currency based on a graph database. Background technique [0002] Blockchain technology has been used in technical fields such as data tracking and certification due to its non-stringent modification and traceability of data. purpose of money. [0003] However, the current technology of tracing and tracking cryptocurrencies relies on experienced personnel to manually search the blockchain browser one path after another, and each path search can only check the relevant transactions of one cryptocurrency address to realize encryption. The single-line pursuit of currency. When such a technology faces the need for multi-level currency transaction network tracking, for example, tracking the cryptocurrency laundering network and relying on manual manual retr...
