Systems and methods for identifying patterns in blockchain activities based on multi-modal data using artificial intelligence models that compensate for training data featuring a high proportion of missing data points. For example, the system may receive blockchain activity record data for a plurality of blockchain activities involving a plurality of blockchain accounts. The system may input the data into an artificial intelligence model, wherein the artificial intelligence model is trained to identify serial relationships of related blockchain activities corresponding to inputted target blockchain activities based on proportions of digital assets at subsets of blockchain accounts of the plurality of blockchain accounts. The system may receive an output from the artificial intelligence model. The system may generate for display, in a user interface, a visualization of the target blockchain activity based on the output.
