Disclosed are methods and systems for quantifying degrees of association between blockchain addresses in a weighted-linked database. The method may include: obtaining a node data set comprising one or more nodes and edges; associating a first node of the node data set with a first weight factor; identifying a first edge of the node data set, wherein the first edge comprises data indicating a source node address corresponding to the first node, a target node address corresponding to a second node of the one or more nodes in the node data set, and a first edge weight; determining a source value for the second node based on the first weight factor and the first edge weight; generating, a risk value for the second node based on the source value; and presenting, on a GUI, graphical depictions of the first node, the second node, and the first edge.
