Title:
BLOCKCHAIN ADDRESS CLASSIFICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/228392
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of computers. Disclosed are a blockchain address classification method and apparatus. One specific embodiment of the method comprises: acquiring blockchain transaction information, wherein the blockchain transaction information indicates one or more transaction input addresses and one or more transaction output addresses; constructing a transaction bipartite graph corresponding to the blockchain transaction information; obtaining, according to the transaction bipartite graph and a graph embedding algorithm, address vectors respectively corresponding to the one or more transaction input addresses and the one or more transaction output addresses; and using the address vectors as inputs of an address classifier to classify the transaction input addresses and/or the transaction output addresses by using the address classifier. The embodiment improves the accuracy of blockchain address classification.
