CoinJoin
Privacy● Common
A privacy technique where multiple users combine their transactions into one, making it difficult to determine which inputs paid which outputs. All participants sign; no trust or custody required. Effective when outputs are equal-sized. Implementations: Whirlpool, JoinMarket, Wasabi.
Technical Notes
Breaks common-input-ownership heuristic. Anonymity set = number of equal outputs. Coordinator can be blinded (ZeroLink) so they can't link inputs to outputs. Post-mix behavior critical: avoid recombining with toxic change. May trigger exchange scrutiny.
