1. A method for verifying a virtual avatar, comprising:
determining, based on the virtual avatar and a plurality of reference images in an image library, a first similarity set comprising a plurality of similarities between the virtual avatar and the plurality of reference images;
selecting a plurality of candidate images from the plurality of reference images based on the first similarity set and a predetermined number;
determining a second similarity set comprising a plurality of similarities between the virtual avatar and the plurality of candidate images;
determining a verification result for the virtual avatar based on a subset in the first similarity set that is associated with the plurality of candidate images, and the second similarity set; and
generating a non-fungible token for the virtual avatar based on the verification result;
wherein determining a verification result for the virtual avatar comprises:
merging the subset and the second similarity set to obtain a third similarity set;
determining the verification result to be normal in response to absence of a similarity in the third similarity set that exceeds a threshold value; and
determining the verification result to be abnormal in response to presence of a similarity in the third similarity set that exceeds the threshold value.
