## Address Reuse Detection

Address reuse detection is the identification of instances where a user utilizes the same blockchain address for multiple transactions. In many protocols, reusing addresses is a significant privacy risk because it allows observers to link disparate transactions to the same entity over time.

While some users reuse addresses for convenience, it creates a trail that is easily analyzed by forensic tools. Detection of this practice is a simple but effective heuristic for clustering addresses and identifying long-term patterns of activity.

It is a common mistake that significantly reduces the efficacy of pseudonymity. Analysts use this data to build more accurate maps of user behavior and to identify the lifecycle of individual assets.
