They use vertex-centric algorithms like Breadth-First Search and Depth-First Search to identify risky nodes, and graph-centric algorithms like Connected Components and Page Rank to find clusters of fraudulent actors. The data processing and serving is done through a combination of offline batch processing and real-time streaming. These algorithms have helped Robinhood save millions of dollars in potential fraud losses. ## Full article daily.dev links to this article rather than hosting it.
