CashShuffle
privacy · bitcoin-cash
A legacy Bitcoin Cash CoinJoin protocol that coordinated equal-denomination outputs to weaken input-output ownership links.
CashShuffle coordinated several BCH users into one transaction with equal-value participant outputs. Because those outputs shared a denomination, an observer could not assign them by amount alone.
Equal denominations, change outputs, network metadata, later consolidation, and low participation can reduce privacy. CoinJoin changes transaction-graph heuristics; it does not hide the transaction or guarantee anonymity.
CashShuffle is primarily a historical predecessor to CashFusion in the BCH wallet ecosystem. CashFusion supports multiple inputs and non-uniform outputs and is the maintained privacy option in compatible current wallets.
