Method and Apparatus for Classifying Blockchain Address

The present disclosure relates to the technical field of computers, in particular to a method and apparatus for classifying a blockchain address. The method includes: transaction vectors are generated for transaction records corresponding to each blockchain address in a blockchain address set; a corresponding address vector is generated based on the transaction vectors corresponding to a blockchain address to be classified; and the address vector of the blockchain address to be classified is input into a classifier, so as to determine a class of the blockchain address to be classified. By means of the method, equal-length vectors representing the blockchain addresses can be obtained for classification by the classifier, transaction behaviors and association relationships of participating entities in a blockchain are effectively expressed.
