CoinJoinXT and CoinJoin Unlimited: stealthier Bitcoin mixing

Performing CoinJoins is one of the simplest and most effective ways for individuals to secure their privacy on-chain. CoinJoins allow users to mix their funds with those of other participants in a single transaction, obscuring the relationship between the transaction’s inputs and outputs and rendering the common-input heuristic useless.

Equal-output CoinJoins, which are the most common CoinJoin variant, are potentially detectable on-chain due to their unique structure in which the transaction contains a number of equally-sized outputs.
