CRYPTOCURRENCY TRANSACTION ANALYSIS METHOD AND SYSTEM

The present invention relates to a method and system for analyzing cryptocurrency transactions, and more particularly, a method and system for analyzing and processing cryptocurrency data using attributes of cryptocurrency to analyze a transaction flow of cryptocurrency, which has been difficult to grasp in the past. The present invention is a method of analyzing a cryptocurrency transaction by an electronic device and is characterized by including a blockchain management step of collecting distributed ledger information of a blockchain corresponding to a specific cryptocurrency and standardizing blockchain data extracted from the distributed ledger information, a multi-type data management step of collecting and standardizing multi-type data related to the cryptocurrency transaction on a Web, a graph generation step of constructing a cryptocurrency network graph using the standardized blockchain data, constructing a knowledge graph using the standardized multi-type data, and mapping the cryptocurrency network graph and the knowledge graph to generate a multi-layer based transaction analysis knowledge graph, and a graph analysis step of searching for transaction information using a first cryptocurrency address for which a fund flow is to be tracked as an input address in the transaction analysis knowledge graph, generating a fund flow graph having the input address and an output address as nodes to track a fund flow, and identifying an attribute of each node included in the fund flow graph using the knowledge graph. According to the present invention, it is possible to analyze a transaction flow of cryptocurrency and identify a transaction subject.
