Mixing / Tumbling (CoinJoin)

concept

Core idea

Pools multiple users’ funds into a single equal-value, multi-party transaction, or routes through a custodial tumbler, so outputs can’t be matched back to specific inputs.

When to use

Equal-value, multi-input/multi-output transaction structure; treat downstream funds as unattributable past this point absent other evidence.

Example

Equal-value inputs from many parties produce equal-value outputs, severing the link between who sent and who received.
