CashFusion
privacy · bitcoin-cash
An opt-in Bitcoin Cash CoinJoin protocol that combines many inputs and differently sized outputs to complicate transaction-link analysis.
1.general
CashFusion is a non-custodial Bitcoin Cash privacy protocol. Multiple participants collaborate on one transaction containing many inputs and outputs of varied amounts, creating many plausible input-to-output assignments for a transaction-graph analyst.
2.coordination
A coordinator helps assemble rounds, but the protocol uses blinded commitments and participant verification so the coordinator should not learn a complete ownership map or gain custody of funds. Implementations commonly use Tor to reduce network-level linkage.
3.measurement
The number of mathematically possible mappings is an upper-bound description of transaction ambiguity, not a user's guaranteed anonymity set. Amounts, timing, wallet fingerprints, coordinator observations, address reuse, exchange records, and later consolidation can eliminate possibilities.
4.safety
Participants should use maintained software, verify the transaction before signing, and preserve coin separation afterward. CashFusion improves resistance to some chain-analysis heuristics; it does not hide the transaction, remove all side channels, or make funds untraceable.
