CoinJoin / Mixer Detection

Core idea

Identifies equal-value, multi-party transactions or centralised mixing services designed to break the on-chain link between sender and receiver. Detection relies on pattern recognition of output structure.

When to use

Transaction outputs show anomalous equal-value, multi-input/multi-output structures signalling deliberate obfuscation.

Avoid when

Mixer use alone is not illegal in most jurisdictions, so do not treat it as proof of a crime; however, funds touching a sanctioned mixer trigger strict-liability exposure downstream.

Example

A transaction with many equal-value inputs and outputs is flagged as a CoinJoin, and downstream tracing is treated as broken past that point absent other evidence.
